    Mechanistic Bases for Effects of Nitrate Supplementation on Metabolism

    Stephen J. Bailey, Anni Vanhatalo, Paul G. Winyard, Andrew M. Jones, FACSM. University of Exeter, Exeter, United Kingdom.

    (No relationships reported)

    We have previously reported that dietary supplementation with nitrate (NO3-)-rich beetroot juice can reduce the oxygen cost of exercise in association with a reduced ATP cost of muscle force production. Dietary supplementation with sodium nitrate (NaNO3-) has also been shown to improve exercise efficiency by increasing the mitochondrial P/O ratio, determined in isolated human mitochondria in situ. Recent data from our laboratory indicates that dietary NO3- supplementation can also reduce the oxygen cost of exercise in older humans, but the mechanistic bases for this effect has yet to be investigated.

    PURPOSE: To investigate the mechanistic bases for the improved exercise efficiency observed after dietary NO3- supplementation in younger and older adult humans in vivo using 31P-MRS.

    METHODS: In a double-blind, crossover study, eight younger adults (age: 19-45 yrs) and twelve older adults (age: 60-70 yrs) consumed 2 × 70 mL per day of either a concentrated NO3--rich beetroot juice (BR; ∼0.3 g NO3-) or a NO3–depleted beetroot juice placebo (PL; ∼0.00074 mg NO3-) for three consecutive days. On the third day of each dietary intervention period, subjects completed two 24 s bouts of high-intensity single-legged knee-extensor exercise in the supine body position within the bore of a 1.5-T superconducting magnet. Muscle oxidative function was estimated in vivo from the post-exercise recovery time constant (τ) of intramuscular phosphocreatine (PCr).

    RESULTS: The PCr recovery τ was not different after NO3–rich beetroot juice (BR) supplementation compared to NO3–depleted beetroot juice (PL) supplementation in either younger (BR: 24 ± 4 s vs. PL: 24 ± 3 s) or older (BR: 37 ± 15 s vs. PL: 35 ± 10 s) adults (P>0.05).

    CONCLUSIONS: The intramuscular PCr recovery τ after short-duration, high-intensity exercise, which provides a non-invasive assessment of the muscle oxidative function in vivo, was not significantly impacted by NO3- supplementation in either younger or older adults. These data suggest that the mechanistic bases for the improved exercise efficiency after dietary NO3- supplementation is not related to muscle oxidative function as assessed by the PCr recovery τ and does not change with the process of aging.

    Effects of Nitrate Supplementation in Normoxia and Hypoxia

    Anni Vanhatalo, Jonathan Fulford, Stephen J. Bailey, Paul G. Winyard, Andrew M. Jones, FACSM. University of Exeter, Exeter, United Kingdom.

    (No relationships reported)

    Hypoxia is associated with a reduction in the maximal oxidative metabolic rate which is reflected in a slowing of phosphocreatine (PCr) recovery kinetics following exercise. Nitric oxide (NO) is a key signalling molecule for hypoxic vasodilatation and it also modulates mitochondrial O2 consumption. Dietary nitrate intake, which increases nitrite and NO bioavailability, might therefore improve O2 delivery to active muscle during hypoxic exercise. Indeed, it has been shown that nitrate supplementation attenuates the detrimental effects of hypoxia on exercise tolerance and [PCr] recovery kinetics. To what extent these effects can be attributed to changes in muscle energy metabolism and/or improved O2 delivery, however, is not clear.

    PURPOSE: To investigate the inter-related effects of dietary nitrate supplementation on muscle energy metabolism and blood flow under conditions of limited O2 availability.

    METHODS: Following ethical approval, eight moderately trained volunteers were tested in a double-blind, randomised crossover study design. Subjects were tested in normoxia (21% O2 in balance N2) and in hypoxia (13% O2) following nitrate and placebo supplementation. The exercise protocol consisted of a constant-work-rate bout of heavy intensity exercise and short bouts of high-intensity knee-extension exercise for the assessment of [PCr] recovery time constant. Muscle metabolism was assessed during and after exercise using calibrated 31P-magnetic resonance spectroscopy and muscle blood flow and oxygenation were assessed using a range of non-invasive nuclear magnetic resonance techniques.

    RESULTS: The PCr recovery time constant was reduced (P<0.05) in hypoxia (29 ± 5 s) compared to normoxia (23 ± 5 s) and hypoxia following nitrate supplementation (24 ± 5 s). Novel data will be presented which describe indices of haemodynamics in large vessels, tissue oxygenation and inflow, and microvascular perfusion.

    CONCLUSIONS: The findings of this study build upon recent work showing that the deleterious effects of systemic hypoxia on muscle energetics and exercise tolerance may be ameliorated by increasing NO availability by a simple dietary intervention. Dietary nitrate could therefore promote exercise tolerance at moderate to high altitude and in disease conditions where O2 delivery to muscle is reduced.

    Diet Impacts Blood Flow Control and Matching Muscle O2 Delivery-to-Utilization

    Nitric oxide (NO) modulates skeletal muscle hemodynamic and metabolic control. Nitrate supplementation elevates NO bioavailability following its reduction to nitrite and NO via NO synthase-independent pathways. Recently, dietary nitrate supplementation has been reported to reduce blood pressure, lower the O2 cost of exercise and increase exercise tolerance. However, it is unknown whether a nitrate-rich diet modulates muscle blood flow (BF) and local O2 delivery-utilization matching (i.e., microvascular O2 pressure; PO2mv) during metabolic transients.

    PURPOSE: To test the hypotheses that acute dietary nitrate supplementation (1) decreases mean arterial pressure (MAP) while preserving resting and exercising skeletal muscle BF and (2) elevates PO2mv from rest to contractions.

    METHODS: Young male Sprague-Dawley rats were randomized into control (n=10) or nitrate-supplemented (beetroot juice, BR; n=12) groups. Either untreated or nitrate supplemented (0.1625 mmol nitrate/day) tap water was available ad libitum for 3 days. Following supplementation, hindlimb muscle BF was measured using radiolabeled microspheres at rest and during submaximal treadmill running (20 m/min, 5% grade) and PO2mv was assessed via phosphorescence quenching in the spinotrapezius muscle at rest and during 1 Hz twitch contractions.

    RESULTS: Despite reduced MAP at rest (↓15%) and during treadmill running (↓10%; p<0.05 for both), all 28 examined individual hindlimb muscles or muscle parts showed no changes in BF both at rest and during exercise after BR supplementation. Moreover, BR supplementation improved PO2mv kinetics during contractions in the spinotrapezius muscle by lowering the amplitude of PO2mv fall by 23% and slowing the relative rate of PO2mv fall by 31% (p<0.05 for both).

    CONCLUSIONS: Dietary nitrate supplementation with BR (1) did not change exercising muscle BF despite reduced MAP and (2) increased muscle microvascular oxygenation (improved PO2mv kinetics) following the onset of contractions. As dictated by Fick’s law of diffusion, elevated driving pressure of O2 in the microcirculation facilitates transcapillary O2 flux and likely constitutes an important mechanism for improved metabolic control and enhanced exercise tolerance following a nitrate-rich diet.

    A Flexible Approach to Diet is Beneficial for Exercise-Induced Weight Loss

    Jackson H. Coppock, John M. Jakicic, FACSM. University of Pittsburgh, Pittsburgh, PA.

    (No relationships reported)

    Two-thirds of adults in the US are overweight or obese and at an increased risk for chronic diseases such as diabetes, CVD, and some cancers. Physical activity (PA) is a common approach to weight loss in the lay public, but PA in the absence of dietary intervention produces varied results. Dietary restraint (DR) often increases in individuals seeking weight loss, even in the absence of dietary intervention. However, the type of restraint (rigid or flexible) appears to influence the resulting weight outcomes and may help explain the range of weight changes resulting from exercise.

    PURPOSE: The purpose of this investigation is to determine whether individuals who lose, maintain, or gain weight in the context of a PA only intervention experience differential changes in their eating behaviors, specifically rigid and flexible control of eating.

    METHODS: Participants (n = 159; BMI = 27±1.73 kg/m2; age = 45.5±7.69 years) were enrolled in an 18-month PA intervention with no dietary component. At 18-months, subjects were retrospectively grouped as having lost > 3% of baseline weight (WL), remained weight stable within±3% (WS), or gained >3% of baseline weight (WG). FC and RC were assessed using the three-factor eating inventory questionnaire, and physical activity (kcal/week) was assessed using the Paffenbarger Questionnaire. Body weight, FC, RC and PA were assessed at baseline and 18 months.

    RESULTS: ANOVA revealed a significant difference in weight change at 18 months between groups (WL = -7.16± 3.43 kg; WM = -0.061± 1.73 kg; WG = 5.07± 2.15 kg; p < 0.001). The increase in PA at 18 months was greater in WL and WM (830.4±1257 and 786±995 kcal/week) than in WG (283±1517 kcal/week) (p = 0.068). The increase in FC was significantly greater in WL (1.75±1.89) compared to both WM (0.69±1.79) and WG (0.98±1.52) (p = 0.005). There was no significant difference between weight loss groups for change in RC (WL = 1.15±1.79; WM = 0.80±1.32; WG = 1.02±1.57, p = 0.465).

    CONCLUSIONS: Dietary restraint appears to influence weight changes resulting from PA intervention. These data suggest that individuals who successfully lose weight by targeting PA benefit from adopting a flexible approach to dietary change, while adopting a rigid approach to diet may not be effective for weight loss.

    Predictors of Weight and Waist Circumference Changes in Abdominally Obese Women: Exercise or Diet Factors?

    Whitney M. Sweat, Kari D. Pilolla, Melissa K. Princehouse, Melinda M. Manore, FACSM. Oregon State University, Corvallis, OR.

    (No relationships reported)

    Obesity and increased waist circumference (WC) increases risk for metabolic syndrome (MetS) and associated chronic diseases. Low-energy dense (LED) diets, emphasizing whole food eating patterns, have not been examined in combination with moderate (Mod)-high (Hi) intensity physical activity (PA) or dietary protein levels to determine their impact on changes in body weight (BW) and WC.

    PURPOSE: To determine the effect of two 16-wk diet and PA interventions, differing in protein intake, on BW, WC, dietary patterns, energy density (ED), and min of Mod-Hi PA.

    METHODS: Healthy, abdominally obese (WC ≥80cm) women (n=38; 34±10y) were randomly assigned to either a 15 or 25% energy from protein diet. Individualized LED diets plans decreased energy intake (EI) by ∼300kcal/d; PA 5 d/wk (30-60 min/d) consisted of supervised Zumba classes (Hi PA, ≥65%HRmax; ≥6METs) and self-selected Mod intensity PA (≥3METs). Servings of fruits/vegetables (F+V), whole grains (WG), and low-fat/fat-free dairy (LFD), fiber, high calorie beverages (BEV), ED, and PA were monitored before (T1), during (T2) and after (T3) the intervention using repeated measures ANOVA.

    RESULTS: At T1, groups did not differ in dietary patterns, PA, BW or WC. Groups responded similarly to the interventions; data were combined, with BW and WC decreasing (p<0.0001) by -4.8±2.7kg and -7.1±3.6cm, respectively. Comparing T1 vs. T2, there were increases (p<0.0001) in F+V (Δ=+1.5 ser/d), WG (Δ=+1.0 ser/d), LFD (Δ=+0.5 ser/d), fiber (Δ=+5.7g/1000kcal), and decreases in BEV (Δ=-165kcal/d) and ED (Δ=-0.55kcal/g). During the intervention Hi PA was 87min/wk; total min of all Mod PA increased by 75 min/d (p<0.0001); VO2max improved from 29.3±4.7 (T1) to 34.4±5.3 (T3) mL/kg/min (p<0.0001). Significant predictors of BW loss were increases in F+V and LFD, and decreases in EI and ED, while predictors of reduced WC were increases in WG, fiber, LFD, and min/wk of Hi intensity PA (Zumba).

    CONCLUSIONS: For abdominally obese women, an intervention focused on LED foods and Hi intensity PA significantly reduced BW and WC and improved dietary patterns regardless of protein intake. Helping clients identify a few key factors that positively change BW and WC may improve weight loss success, while reducing MetS risk factors.

    Ghrelin Is Associated With Compensatory Appetite Responses To Exercise In Obese Adults

    Exercise is promoted as a method of weight loss for obese people, but often results in lower than expected weight loss. Ghrelin is a hormone associated with the drive to eat but paradoxically excess body weight is associated with lower ghrelin levels. Controlled exercise training has been shown to affect appetite including increased sensations of fasting hunger but also increased satiety after meals. The mechanism behind these changes - and specifically the role of ghrelin - is unknown.

    PURPOSE: To examine the role of ghrelin in appetite and compensatory energy intake (EI) following a 12 week mandatory program of exercise training in obese adults.

    METHODS: A 12-week, fixed energy expenditure (EE), supervised exercise intervention was conducted in 49 overweight and obese individuals (M:17, F:32; Mean Age, 43yrs; Mean BMI, 31kg/m2). Exercise was individually prescribed to achieve a gross EE of 2500kcal/week. At week 0 and 12, body composition, fasting ghrelin (n=30), subjective appetite ratings, satiety effect of a fixed breakfast and 24hr EI were objectively measured.

    RESULTS: We observed significant decreases in BMI, BM, %BF, FM and WC (all p<0.001), and increases in FFM (p<0.05). After exercise training, 24hr EI did not change (-83.3±62.4kcal, p=0.151). However, fasting ghrelin (66.4±26.3pg/ml) and fasting hunger (8.47±3.3mm) had increased (all p<0.05), whilst the post-ingestive satiating power of food increased (p<0.05). Changes in ghrelin levels were negatively associated with changes in BMI (r=-0.374), %BF (r=-0.371) and FM (r=-0.365) and positively associated with hunger (r=0.409) (all p=<0.05).

    CONCLUSIONS: Exercise training should be advocated as a method to improve appetite regulation in obese adults. In this 12-week program of supervised exercise, body mass was reduced which was related to an increase (i.e. normalisation) in fasting levels of ghrelin. Intuitively, the increase in ghrelin was positively associated with a compensatory increase in hunger, however, any effect on food intake was countered by a dual action increase in postprandial satiety. Therefore exercise has a sensitising action on physiological regulation of ghrelin and appetite without a concomitant increase in EI.

    Neither Ca2+ release nor AMPK-activation suffices to stimulate skeletal muscle glucose transport.

    Ca2+ is believed to mediate feed-forward stimulation of glucose transport during skeletal muscle contraction which is subsequently adjusted to the actual substrate demand of the working muscle by poorly defined metabolic feed-back signals which may include AMP-activated protein kinase (AMPK).

    PURPOSE: To investigate the relative sufficiency of Ca2+ and metabolic feedback to increase glucose transport.

    METHODS: Combined BTS and blebbistatin (Bleb) was used to inhibit slow and fast myosin class II (MyoII) ATPase isoforms to nearly prevent tension development in incubated mouse slow-twitch soleus and fast-twitch EDL muscles. This was combined with either the SERCA inhibitor cyclopiazonic acid (CPA), to block ATP-consuming Ca2+ reuptake and elicit a sustained low-level increase in cytosolic Ca2+, or one of three ex vivo contraction-protocols representing work-intensities of 0.1, 0.3 and 0.7% net stimulation time (NST).

    RESULTS: With MyoII inhibitors present, CPA-stimulated glucose uptake was 30% of control in soleus, paralleled by reductions in energy turnover and AMPK Thr172 phosphorylation. None of these parameters changed in EDL, despite Ca2+ activation of eukaryotic elongation factor 2 (eEF2) Thr56 phosphorylation. MyoII inhibition abolished contraction-stimulated glucose uptake at the 0.1% NST intensity in both muscles, had an ∼50% inhibitory effect at the 0.3% NST intensity and caused a 35% reduction in soleus, but not EDL, at the 0.7% NST intensity. Energy turnover and AMPK Thr172 phosphorylation were reduced by MyoII inhibition at all contraction-intensities. However, AMPK Thr172 and downstream ACC Ser212 phosphorylation still increased significantly at the lowest 0.1% NST contraction-intensity when no increase in glucose transport was detectable.

    CONCLUSIONS: These data indicate that increased Ca2+ and AMPK activation are not sufficient signals to stimulate glucose transport in skeletal muscle.

    Rac1-activation is a Novel Candidate for Regulating Glucose Metabolism in Response to Contraction in Skeletal Muscle

    The cortical actin-cytoskeleton and the actin-regulatory GTPase Rac1 are required for insulin-stimulated GLUT4 translocation and glucose uptake in cell culture and mature muscle. Failure of insulin to cue actin-remodelling has been proposed as a major defective step in insulin resistant states. In humans, exercise can stimulate glucose uptake in insulin-resistant muscle and acutely reverse insulin resistance but it is hitherto uninvestigated whether contraction-stimulated glucose uptake requires an intact actin-cytoskeleton and whether exercise activates Rac1.

    PURPOSE: To investigate the involvement of the actin-cytoskeleton and Rac1 in regulation of insulin and contraction-stimulated glucose uptake in skeletal muscle.

    METHODS: Rac1-activity was measured using a commercially available ELISA kit. To investigate the involvement of the actin-cytoskeleton and Rac1 in regulating insulin and contraction-induced glucose uptake, 2-deoxyglucose uptake was measured in incubated mouse soleus and EDL muscles pretreated with or without the actin-depolymerising agent latrunculin B or two structurally different Rac1 inhibitors (NSC23766 and Rac1 inhibitor II).

    RESULTS: In humans, Rac1 activity was increased by 1.3-fold in vastus lateralis after 2 hour hyperinsulinemic euglycemic clamp (P=0.01). Interestingly, also 45 min of inclined (15 %) walking exercise at ∼ 70 % VO2 peak increased Rac1 activity by 1.4- and 1.3-fold in human soleus (P<0.01) and gastrocnemius (P<0.05), respectively. In mice, an exercise bout of 70% max running speed increased Rac1 activity 1.9-fold (p<0.05) in gastrocnemius muscle. In incubated mouse muscle, latrunculin B inhibited insulin-stimulated glucose uptake by 50 % and 60 %, and contraction-induced uptake by 100 % and 70 %, in soleus and EDL, respectively. In addition, inhibition of Rac1 decreased contraction-stimulated glucose uptake by 50-80 % and 30-50 % in soleus and EDL, respectively, suggesting that the involvement of the actin-cytoskeleton in glucose uptake may be mediated through Rac1-activation.

    CONCLUSIONS: These data show for the first time that exercise and insulin in humans and exercise in mouse increase muscle Rac1 activity and suggest that both insulin- and contraction-stimulated glucose uptake require an intact actin-cytoskeleton regulated by Rac1.

    The Interplay Between NCoR1 and PGC-1α Regulates Skeletal Muscle Oxidative Metabolism

    INTRODUCTION: The metabolic fitness of skeletal muscle is an essential factor in the modulation of whole body energy homeostasis. In fact, an impairment of skeletal muscle energy metabolism has a direct impact on the prevalence to metabolic diseases. The regulation of muscle function relies to a great extent in the action of different transcription factors and coregulators. The proliferator-activated receptor (PPAR) γ coactivator 1α (PGC-1α) has been shown to play a key role in the control of muscle function by increasing gene transcription. Conversely, the nuclear receptor corepressor 1 (NCoR1) has the ability to promote transcriptional repression by assembling a large protein complex. However, its role in muscle physiology only starts to be explored.

    PURPOSE: The aim of this study was to investigate the physiological role of NCoR1 in skeletal muscle.

    METHODS: To specifically study NCoR1 in skeletal muscle we have used NCoR1 muscle-specific knockout (MKO) mice. Whole body energy homeostasis and muscle function of MKO mice was assessed during basal conditions, exercise and ex vivo. Moreover, molecular and bioinformatics analysis of MKO skeletal muscle was performed. Finally, C2C12 myotubes were used to study the mechanisms by which NCoR1 regulates muscle oxidative metabolism.

    RESULTS: We have found that NCoR1 deletion in striated muscle does not affect body composition and basal energy metabolism. Nonetheless, similar to endurance athletes, MKO mice exhibited an improved insulin tolerance test, peak oxygen uptake and ex vivo fatigue resistance. Furthermore, mRNA content of mitochondrial enzymes and the proportion of oxidative fibers were increased in MKO animals. Consistently with the role of PGC-1α in skeletal muscle, we have found that the up-regulation of mitochondrial enzymes induced by NCoR1 knockdown in cultured myotubes was ERRα-PGC-1α dependent.

    CONCLUSIONS: Taken together, these data indicate that NCoR1 regulates skeletal muscle oxidative metabolism in an opposite way to the ERRα-PGC-1α complex, emerging thus as a new potential therapeutic target for metabolic diseases.

    Age-related differences in the senescent CD8+ T-cell response to acute exercise: are they infectious?

    Richard J. Simpson, Austin B. Bigley, Guillaume Spielmann, Emily C.P. LaVoy, Mark Morrison, Mira Momcilovic. University of Houson, Houston, TX.

    (No relationships reported)

    Acute-exercise elicits a preferential mobilization of memory and senescent subsets of CD8+ T-cells into the blood. Although this response is affected by age, latent cytomegalovirus (CMV) infection in young people also amplifies the mobilization and proportional shifts of these cells with exercise. As CMV prevalence increases with age, the CD8+ T-cell response to acute exercise may be a property of CMV infection and not age per se.

    PURPOSE: To determine the impact of age and latent CMV infection on the response of CD8+ T-cells and their subsets to an acute bout of aerobic exercise.

    METHODS: 16 young (Y; 20-35yrs) and 16 older (O; 50-64yrs) healthy men (n=32) completed a 30-minute cycling protocol at 80% maximum power. 8 participants in both Y and O were seropositive (pos) for latent CMV infection (n=16). Blood lymphocytes isolated before, immediately after and 1h after exercise were surface stained and analyzed by 4-color flow cytometry for numbers and proportions of CD3+/CD8+ T-cells and naïve (KLRG1-/CD28+), memory (KLRG1+/CD28+) and senescent (KLRG1+/CD28-) CD8+ T-cell subsets. Main effects of exercise, age, CMV and interaction effects were determined using linear mixed model analysis.

    RESULTS: Relative physiological responses to exercise were not affected by age or CMV infection. Exercise increased numbers of senescent, memory and naïve CD8+ T-cells, which returned to (naïve) or fell below (memory; senescent) baseline values 1h later. Main effects of age (+32%), CMV (+24%), and an age x CMV interaction were found for proportions of senescent CD8+ T-cells. CMVpos had an amplified mobilization (ingress; 61% v 29%) and extravasation (egress; 66% v 30%) of senescent cells as a percentage of all CD8+ T-cells compared to CMVneg. No differences were found between Yneg and Oneg for the ingress (29% v 29%) or egress (31% v 29%) of senescent CD8+ T-cells. However, this response was greater in Opos than Ypos for ingress (66% v 55%) and egress (82% v 50%).

    CONCLUSIONS: Latent CMV infection has a remarkable effect on the mobilization of CD8+ T-cells and their subsets in response to acute aerobic exercise. Because no age-related differences to exercise exist in the absence of CMV, these data indicate that latent CMV infection is the driving force behind the apparent age-related effects on the CD8+ T-cell response to acute aerobic exercise.

    Acute Exercise Increases Cytokine Expression In Late But Not Early Differentiated CD8+ T-cells In Humans

    Emily C. LaVoy, Richard J. Simpson. University of Houston, Houston, TX.

    (No relationships reported)

    Acute exercise preferentially mobilizes antigen-experienced CD8+ T cells into the blood compartment, which could have important implications for post-exercise immune surveillance. Although acute exercise alters type 1 and type 2 cytokine expression in total CD8+ T cells, it is unknown if this response is due to a shift in the proportions of early and late differentiated CD8+ T cells, as late differentiated cells are mobilized in relatively greater numbers in response to exercise.

    PURPOSE: To determine if an exercise induced shift in the proportions of early (CD27+) and late (CD27-) differentiated cells influences intracellular cytokine expression of pan CD8+ T cells, and to determine if the cytokine response to acute exercise is influenced by the proportion of late differentiated cells in resting blood.

    METHODS: 16 trained male cyclists (33±5 yrs) cycled 60 min at 95% maximal steady state. Blood samples were collected before, immediately after, and 1h after exercise. Isolated lymphocytes were cultured 13h at 37°C with and without 2.5 μg/ml PHA and assessed for CD8+ T cell differentiation markers and intracellular cytokine expression by flow cytometry.

    RESULTS: Independently of PHA stimulation, exercise increased the frequency and proportion of CD8+ T cells expressing IL-2, IFN-γ, TNF-α, IL-6, IL-4, and IL-10 1h post exercise. The elevated cytokine expression was localized to late differentiated CD27- CD8+ T cells. Strikingly, this cytokine response was absent in subjects with elevated late:early differentiated T cell ratios (n=8) despite their greater ingress (118 v 62 cells/μl) and subsequent egress (-152 v -75 cells/μl) of CD27-CD8+ T cells in response to exercise.

    CONCLUSIONS: Exercise increases expression of both anti- and pro-inflammatory cytokines in CD8+ T cells during the recovery phase of exercise. This effect is localized to a population of late differentiated CD27- T cells, indicating that the response is not due to proportional shifts in early and late differentiated T cells with exercise. Cytokine expressing cells did not change with exercise in individuals with elevated proportions of late differentiated CD8+T cells at rest. Whether this is due to a mobilization of exhausted T cells or to a more rapid extravasation (<60min) of the cytokine expressing cells in these subjects remains to be determined.

    Confidence Matters, but what Kind and When? Exploring Different Types of Self-Efficacy for Exercise

    Terra Murray. Athabasca University, Athabasca, AB, Canada.

    (No relationships reported)

    Self-efficacy is generally considered a robust predictor of exercise behavior. More recent research is beginning to explore different types of self-efficacy related to exercise, including task, coping and scheduling self-efficacy. Different types of self-efficacy may be important correlates of exercise in different groups of individuals.

    PURPOSE: To explore different types of self-efficacy in relation to exercise in two separate groups of people, those from the community (study 1) and those attending a CR program (study 2).

    METHODS: Study 1 (N = 350) utilized a one time, cross sectional survey. In study 2 (N = 107) a prospective design was used. Measures were assessed prior to beginning, end and 1 month post rehabilitation.

    RESULTS: In study 1, scheduling self-efficacy (along with a distal control belief, personal constraints) mediated the relationship between indictors of socioeconomic status and exercise. In study 2, results showed that no type of self-efficacy predicted exercise during rehabilitation. However, scheduling self-efficacy predicted exercise after rehabilitation.

    CONCLUSIONS: Findings from both studies support conceptualising self-efficacy in terms of multiple dimensions. Further, results from study 2 suggest that there may be different motivational influences on exercise performed during rehabilitation and on exercise performed once rehabilitation is completed.

    Multiple Levels Of Influence On The Physical Activity And Sedentary Behaviors Of Adolescents Residing In Hawaii: The Health Action And Research Training (hart) Project

    Karly S. Geller. Miami University, Oxford, OH.

    (No relationships reported)

    There is emerging recognition that the youth obesity challenge is multifaceted, requiring analysis at multiple levels of influence. One appropriate comprehensive approach is the social ecological framework, targeting influential health factors at multiple levels of influence. The current research examined the relationship- and community-level factors to determine the most salient influences on participating adolescents’ multiple health behaviors. Qualitative and quantitative data were collected in two separate studies. Study I gathered descriptive data during school via surveys and corresponding focus groups. Participating high school students (N=42; 86% female; 86% Filipino; mean age=16.5, SD=0.6) were trained in research methods, and conducted student-led interviews with his/her parent (N=31) about health behavior and parents’ perceived influence. Among a similar sample of youth (N=88; 75% female; 68% Filipino; mean age=16.2 SD=0.6). In Study II, multiple linear regression models were used to estimate mean differences in the metabolic equivalents (METs) of adolescents’ physical activity levels and minutes of sedentary screen time for residing in an area with additional supportive physical activity resources (e.g., gyms, beach parks, etc.). Study I results demonstrated that participating adolescents were more likely to be sedentary with their parents and more physically active with their peers. In Study II, accessibility to greater resources within walking distance of adolescents’ home was positively associated with their MET walking minutes, moderate PA MET minutes, and vigorous PA MET minutes, and total screen minutes per day (all ps<0.00). Further research is needed to determine the contribution of parental/peer influences and community-level accessibility to resources in determining minority adolescents’ multiple health behavior. This study serves as a foundation for future research, leading to the development, implementation, and evaluation of health promotion strategies that would benefit adolescents with similar backgrounds. This project was supported by a postdoctoral fellowship on grant R25 CA90956 from the National Cancer Institute. Thanks to Dr. Claudio Nigg for his contribution to this project.

    PURPOSE: Motivation is a critical factor in supporting sustained exercise participation, which in turn is associated with important health outcomes. Self-determination theory (SDT) is a well-known theoretical framework that explores motivational mechanisms linked to physical activity (PA) adoption and maintenance. SDT-based research has grown considerably in recent years. This study presents a broad review of published empirical data, examining relations between key SDT-based constructs and exercise behavioral outcomes.

    METHODS: This systematic review includes 66 empirical studies published up to June 2011, including experimental, cross-sectional, and prospective studies that have measured exercise causality orientations, need support and need satisfaction, exercise motives/goals, and exercise self-regulations and motivation. We also studied SDT-based interventions aimed at increasing exercise behavior. In all studies, actual or self-reported exercise, including attendance, was analyzed as dependent variable. Findings are summarized based on quantitative analysis of the evidence.

    RESULTS: Results show consistent positive relations between more autonomous forms of motivation and exercise, with a trend towards identified regulation predicting initial/short-term adoption more strongly than intrinsic motivation, and the latter being more predictive of long-term exercise adherence. Perceived competence satisfaction in exercise and more intrinsic motives/goals to be physically active (affiliation, skill development) consistently predicted exercise participation across diverse samples and settings. Mixed evidence was found regarding the role of other types of motives/goals (health/fitness and body-related goals), and the specific nature and consequences of introjected regulation. Most of these studies used descriptive designs but similar results are found across cross-sectional, prospective, and experimental designs.

    CONCLUSIONS: Overall, the literature provides supportive evidence for the value of SDT in explaining exercise` behavior, demonstrating the relevance of developing autonomous regulations and addressing the nature of exercise goals in fostering adherence. Results are discussed in the context of refining SDT application to PA research and promotion.

    The Influence of Hydrostatic Pressure on Human Embryonic Stem Cell Chondrogenesis

    Jennifer K. Lee. University of California Davis, Davis, CA.

    (No relationships reported)

    Current cartilage tissue engineering efforts are subject to the limitations of a renewable cell source, as primary cells are difficult to obtain and often de-differentiate in culture. As a solution, our lab has turned to human embryonic stem cells (hESCs) to generate large numbers of cells for our tissue engineering purposes. We have successfully differentiated hESCs into chondroprogenitor cells and applied them to a self-assembly protocol to form tissue-engineered cartilage constructs. In our primary cell work, we show that mechanical stimuli can improve the properties of our cartilage neotissue.

    PURPOSE: This work aims to enhance the biochemical and biomechanical properties of cartilage tissue generated from hESCs. As joint loading of articular cartilage generates hydrostatic pressure (HP), HP application to hESCs during differentiation is hypothesized to beneficially enhance the expression of cartilaginous markers.

    METHODS: hESCs are differentiated in 1% FBS and 10ng/mL TGF-β1 for 3 weeks as embryoid bodies (EBs). Static HP at 0, 1, and 5MPa is applied for 1 hour per day, during days 15-21 of EB differentiation. EBs are subsequently dissociated into a single cell solution and seeded into non-adherent agarose wells as part of our self-assembly process, and cultured for 4 weeks in chemically-defined, chondrogenic media. The constructs are analyzed at t=4 weeks for biomechanical and biochemical properties. Histology is performed on representative EBs after 3 weeks of differentiation, as well as on constructs at t=4wks.

    RESULTS: All EBs stain positively for total collagen and glycosaminoglycans (GAGs), and negatively for calcification. Construct histology demonstrates presence of collagen and absence of calcification. Minimal GAG staining was present in constructs. After 4 weeks, gross morphology of loaded constructs exhibit significantly greater diameter and weight increases over controls.

    CONCLUSIONS: HP application below physiological levels reveals beneficial results in affecting hESC chondrogenesis, and can cause significant changes in properties of tissue engineered cartilage. The successful combination of HP with chondrogenic stimuli for hESC-based differentiation moves cartilage tissue engineering closer towards establishing clinical solutions for cartilage healing.

    Hypoxia as a method of promoting collagen crosslinking in native and engineered articular cartilage.

    Eleftherios A. Makris, Kyriacos A. Athanasiou. University of California Davis, Davis, CA.

    (No relationships reported)

    The poor ability of articular cartilage (AC) to repair following disease and injury makes the tissue a key target for cell-based regenerative strategies. Hypoxia has been shown to increase collagen pyridinoline (PYR) crosslinks via upregulation of lysyl oxidase (LOX), though this has not been confirmed with chondrocytes.

    PURPOSE: To employ hypoxia-induced LOX crosslinking of cartilage matrix for improving mechanical properties of native and engineered AC.

    METHODS: AC explants from the patellofemoral groove of 6 juvenile calves were cultured for 2 weeks under either hypoxic (4% O2) or normoxic (21% O2) conditions with or without 0.25 mM beta-aminopropionitrile (BAPN), a known LOX inhibitor. Tissue engineered AC contructs formed using a scaffoldless, self-assmebly method were incubated at 4% O2 continuously during 1st and 3rd week, 3rd and 4th week, 4th week, or at 21% O2 continuously during a 4-week culture period. The effects of the applied factors on mechanical properties, biochemical content (collagen, glycosaminoglycans (GAG), DNA, and PYR), and LOX gene expression were evaluated.

    RESULTS: Real time PCR results showed increased LOX gene expression for all hypoxia treated groups. In native AC, a significantly higher amount of PYR was detected in the hypoxia-treated group without BAPN inhibition (43%, p<0.05). Concomitant with the increases in crosslinks, tensile mechanical properties were observed for hypoxia-treated AC (138%) without significant increases in collagen or GAG content. For AC constructs crosslink’s and tensile properties only increased for hypoxia treatment during the 3rd and 4th weeks (16% and 79% respectively, p<0,05). This treatment also resulted in increased cell number per construct (70%) while no significant increases were detected in collagen or GAG content. BAPN abolished all increases in crosslink’s and tensile properties in the applied groups.

    CONCLUSIONS: Hypoxia has been successfully employed for increasing native and engineered AC mechanical properties. Results show that this occurs though LOX-mediated collagen crosslinking, since this process appears to be inhibited by BAPN. The results are clinically significant for AC repair as both AC graft and engineered tissue mechanical properties may be improved using hypoxia for the purpose of transplantation.

    Aging is associated with a reduction in the body’s capacity to dissipate heat as evidenced by an attenuated skin blood flow and sweating response during passive heat exposure. To date however, few studies have examined age-related changes in thermoregulatory function during exercise in the heat in older adults, especially in older females.

    PURPOSE: To investigate the effects of age progression on whole-body heat loss during intermittent exercise in the heat in young and older females.

    METHODS: Direct and indirect calorimetry was used to measure changes in body heat content and metabolic heat production (M-W). Core temperature (Trec) was measured continuously. Five young (Y) (24±3 years) and five older (O) (54±9 years) healthy females matched for body surface area (Y: 1.61±0.04, O: 1.65±0.09) performed four successive bouts of 15-min cycling (Ex1, Ex2, Ex3, Ex4) at a constant rate of heat production (300 W) at 35°C and 20% relative humidity. Each exercise bout was separated by 15 minutes of rest (R1, R2, R3) with a final rest period of one hour (R4).

    RESULTS: Body heat content (kJ) during Ex1 (Y: 114±9, O: 130±10), Ex2 (Y: 78±8, O: 91±7), Ex3 (Y: 72±7, O: 88±8) and Ex4 (Y: 76±6, O: 89±6) were greater in older versus younger females. The older females also had a greater net change in body heat content following each exercise/rest cycle; Ex1/R1 (Y; 93±10, O; 114±11), Ex2/R2 (Y: 41±8, O; 56±7), Ex3/R3 (Y: 31±12, O; 43±10) and Ex4/R4 (Y: 5±19, O; 46±13). The changes in body heat content were paralleled by a larger increase in core temperature from baseline in the older group at the end of Ex4 (Y: +0.59±0.09, O: +0.68±0.07) and following the 1-hour recovery period (Y: +0.22±0.08, O: +0.40±0.05).

    CONCLUSIONS: These findings suggest that older females matched for weight and body composition have a lower capacity for whole body heat loss compared to younger females during intermittent exercise in the heat performed at a fixed rate of metabolic heat production.

    Reflex Cutaneous Vasodilation is Preserved in Human Skin Through Middle Age

    Anna E. Stanhewicz, Lacy A. Holowatz, W. Larry Kenney, FACSM. The Pennsylvania State University, University Park, PA.

    (No relationships reported)

    Thermoregulatory reflex cutaneous vasodilation is attenuated with primary human aging. Studies examining the age-related decrement in control of skin blood flow have been conducted in subjects aged 65-85 years compared to an 18-30 year old group; however little is known about the middle-aged cohort.

    PURPOSE: To retrospectively examine the magnitude of reflex cutaneous vasodilation in three distinct age cohorts (young, middle-aged, advanced age). We hypothesized that the decline in reflex vasodilation would fall on an aging continuum with skin blood flow in middle-aged subjects between that of the young and advanced age cohorts.

    METHODS: We retrospectively analyzed data from three distinct cohorts: 31 young (Y, 18-26 years), 39 middle-aged (MA, 45-56 years) and 31 advanced aged (AA, 65-81 years) men and women. In all protocols subjects were passively heated (water-perfused suit) to increase oral temperature (Tor) by 0.8-1.0°C to induce reflex cutaneous vasodilation. Red blood cell flux was measured as an index of skin blood flow on the ventral forearm by Laser-Doppler Flowmetry (LDF) and cutaneous vascular conductance was calculated (CVC = LDF/MAP) and normalized to maximal (%CVCmax).

    RESULTS: Reflex vasodilation was attenuated in the AA cohort starting at a 0.4°C rise in Tor (p<0.05). There were no differences between the Y and MA cohorts in either %CVCmax or absolute CVC (all p>0.05) across the rise in body temperature. With a 1.0°C rise in Tor %CVCmax was reduced in AA compared to MA and Y cohorts (AA: 32 ± 2 vs. Y: 52 ± 3 and MA: 52 ± 2%CVCmax, both p < 0.05). Further, there were no differences between groups in absolute CVCmax (Y: 1.8 ± 1 vs. MA: 1.7 ± 1 and AA: 1.7 ± 1 CVC; p>0.05).

    CONCLUSIONS: Reflex cutaneous vasodilation is preserved in healthy human skin through middle-age.

    Effects of Aging on Local Heat Loss Responses During Intermittent Exercise in the Heat

    Jill M. Stapleton1, Robert Boushel2, Glen Kenny1. 1University of Ottawa, Ottawa, ON, Canada. 2University of Copenhagen, Copenhagen, Denmark.

    (No relationships reported)

    Older adults typically exhibit reduced local sweat rates (LSR) and skin blood flow (SkBF) during exercise compared to younger individuals. Previous studies have compared responses during exercise at a set percentage of VO2max. As such, the attenuated heat loss responses may simply be due to a lower heat production.

    PURPOSE: To determine if older adults performing heavy intermittent exercise in a hot environment (35ºC, 30% RH) have a similar capacity to dissipate heat regardless of age-related reductions of VO2max.

    METHODS: Seven young (Y) and eight old (O) subjects completed 3 x 15 min cycling, at a rate of metabolic heat production of 584 ± 26 W, separated by 15 min recovery in the heat. Forearm LSR and SkBF, and esophageal temperature (Tes) were measured continuously. Blood pressure was measured at 5 min intervals. Cutaneous vascular conductance (CVC) was calculated as SkBF/mean arterial pressure (MAP). Onset thresholds for LSR and CVC were calculated for each exercise bout.

    RESULTS: Values are mean ± SD. Young and old subjects differed in age (Y: 22 ± 2, O: 64 ± 6) and VO2max (Y: 48.9 ± 9.2, O: 38.5 ± 6.6), but in no other physical characteristics (i.e., height, weight, body fat). Tes was lower at baseline for O compared to Y (O: 36.92 ± 0.21, Y: 37.17 ± 0.22°C, p=0.027), but increased significantly greater from baseline during the second (O: 1.09 ± 0.17, Y: 0.79 ± 0.23°C, p=0.008) and third (O: 1.11 ± 0.30, Y: 0.83 ± 0.19°C, p=0.0433) exercise bouts. LSR was lower in O during the first exercise bout (O: 0.73 ± 0.23, Y: 0.94 ± 0.18 mg/cm2/min, p=0.039) only. The onset Tes threshold for LSR was lower for O compared to Y during the first exercise bout (O: 36.97 ± 0.22, Y: 37.18 ± 0.20°C, p=0.047) only. The %change in CVC from baseline was similar for both groups during each exercise bout (O: 48.8 ± 19.5, 61.9 ± 19.1, 64.0 ± 18.3; Y: 56.9 ± 15.8, 61.8 ± 14.2, 64.4 ± 12.1%). The onset Tes threshold for CVC was lower for O compared to Y during the first exercise bout (O: 36.97 ± 0.22, Y: 37.17 ± 0.24°C, p=0.023) only.

    CONCLUSIONS: Working at a set rate of metabolic heat production allows for the evaluation of heat loss responses while working in the heat, regardless of aerobic capacity. Despite the older adults working at a greater percentage of VO2max and having a greater change in Tes, they were not able to achieve the same capacity for heat loss compared to the younger group.

    PURPOSE: We have reported that maternal exercise during pregnancy results in decreased fetal and infant heart rate (HR) and increased heart rate variability (HRV) when compared to women who did not exercise. Using this same cohort, we explored whether maternal pre-pregnancy BMI has an influence on fetal cardiac autonomic control at 36 weeks gestational age.

    METHODS: We performed a secondary analysis of the data using Spearman’s correlations. Women were classified as healthy weight (HW) if their pre-pregnancy BMI was between 18.5-24.9, and OW/OB if their BMI exceeded 25.0. Women were assigned to the Exercise group if they continued moderate to vigorous aerobic exercise throughout their pregnancy for a minimum of 30 minutes, 3 times a week. Women in the Control group did not report the activity described above. The number of subjects per BMI-physical activity category is as follows: HW Exercise (n=19), HW Control (n=14), OW/OB Exercise (n=5) OW/OB Control (n=13). We used metrics of rate (HR), metrics describing short-term HRV, overall HRV and a metric of vagal function.

    RESULTS: We found that maternal pre-pregnancy BMI did not influence fetal HR and HRV. Correlations showed that fetal HR is significantly influenced by maternal exercise duration (p=0.02) and maternal resting HR (p=0.01), but not maternal BMI or age. Fetal measures of HRV show that maternal exercise duration is a significant predictor of increased HRV (p<0.01), but not her BMI, age, or resting HR (p>0.12). There were no significant differences or correlations with sympathovagal balance.

    CONCLUSIONS: Maternal exercise has a significant effect on fetal cardiac autonomic control that persists to the post-natal period. Although there are trends related to maternal BMI, no significant association with pre-pregnancy BMI and fetal cardiac metrics were seen, suggesting that exposure to maternal exercise throughout gestation has a greater influence on cardiac autonomic development of the offspring. Our study is limited by the small number of subjects and with a primary aim to understand the effects of maternal exercise, not pre-pregnancy BMI on fetal HR and HRV. These findings suggest that maternal aerobic activity while pregnant is a factor in fetal cardiac autonomic control and not pre-pregnancy BMI classification.

    Obesity during pregnancy increases risk of gestational diabetes and preeclampsia, but little is known on how metabolic characteristics during pregnancy may vary by weight status.

    PURPOSE: To examine relations between current weight status and metabolic characteristics among pregnant women.

    METHODS: In this cross-sectional study, self-reported data on pregnancy trimester, personal and family history of high blood pressure, cholesterol, and diabetes, and measured total (TC) and high density lipoprotein cholesterol (HDLc), body mass index (BMI), and c-reactive protein (CRP) were abstracted for pregnant women in NHANES 1999-2006 (n=1173 with complete lipid values). Women were classified as currently healthy weight (<25kg/m2), overweight (25-<30 kg/m2) or obese (30+ kg/m2). Characteristics were compared across weight categories using chi-square statistics and ANOVA. For variables that may change during pregnancy, trimester-specific values were also compared across weight groups. All analyses were weighted to account for the complex sampling frames of NHANES.

    RESULTS: There were 354 (33%) healthy weight, 407 (30%) overweight, and 412 (37%) obese women. Compared to healthy weight women, overweight and obese women had significantly higher prevalence of personal history of high blood pressure (3.5% vs. 8.2% vs. 13.7% for healthy weight, overweight and obese, respectively) and family history of diabetes (34.0% vs. 45.1% vs. 60.4%) (p<0.05). Mean TC was significantly higher among overweight vs. healthy weight women (mean=225, 95%CI: 217-232 vs. 207, 197-216 mg/dl, respectively) while mean HDLc was significantly lower in obese vs. normal weight women (61, 59-64 vs. 68, 65-70 mg/dl, respectively) (p<0.05). Both obese and overweight women had significantly higher mean CRP compared to healthy weight (1.107, 0.92-1.29 and 0.781, 0.50-1.06 vs. 0.401, 0.32-0.48 mg/dl, respectively, p<0.05). In trimester specific analyses, CRP was significantly higher among overweight women in the 1st trimester only and in all trimesters for obese women. HDLc was significantly lower among obese women in the 2nd and 3rd trimesters.

    CONCLUSIONS: In addition to higher rates of personal and family history of metabolic disease, obese pregnant women have less favorable HDLc and CRP levels which may contribute to disease risk.

    Exercise Prescription for Overweight/Obese Pregnant Women

    With the increasing prevalence of obesity world-wide, a healthy lifestyle for pregnant women with a pre-pregnancy body mass index (BMI) of 25 to 29.9 kg/m2 (overweight) and ≥30 kg/m2 (obese) should be initiated. A healthy lifestyle approach appears imperative, yet few studies have initiated an intervention of nutrition control and physical activity for overweight and obese pregnant women. Before initiating a lifestyle change it is important that pregnant women be medically pre-screened by their health care provider using the PARmed-X for pregnancy (www.csep.ca). Once a low-risk pregnancy has been established, walking in combination with nutritional control may be effective in preventing excessive weight gain in overweight and obese women. Maternal exercise prescription should use the FITT principle, with a frequency of 3 to 4 times per week, starting at 25 minutes per session. Intensity based on a target heart rate zone of 110-131 beats per minute for women 20-29 years of age and 108-127 beats per minute for women 30-39 years of age, coupled with use of the rating of perceived exertion scale and the “Talk Test”, can be used in conjunction with a walking program. Further studies are necessary to assist this vulnerable population group in prevention of excessive weight gain during pregnancy and to help them adopt a healthy lifestyle during this time for their future health and the health of their children.
