In this issue we bring you five original research reports all having used observational methods - two prospective, one retrospective and two cross-sectional designs. Each provide great examples of the power and use of observational designs in hypothesis generation and preliminary testing of highly relevant and important clinical hypotheses. Arena et al report on a prospective observational study to describe and compare preseason and postseason blood pressure (BP) measures among collegiate athletes and correlate BP measurement and BMI across a season. Byrd  et al retrospectively evaluate the effect of a one-month physical therapy based outpatient program on exercise capacity, symptoms, quality of life (QOL) and examine predictors of functional outcome changes in adults awaiting lung transplantation. Pepin et al study the association between functional ability and physical activity in individuals with transtibial amputations and highlight a need to consider long term implications of functional gait speed and balance on the likelihood of sedentary behavior including the hypothesized dynamic feedback loop of possible functional decline.  Himes et al report on the relationship among lower extremity blood flow, strength and fall risk in adults enrolled in phase II cardiac rehabilitation.  And Blackwood et al examine relationships between cognitive performance and physical mobility in community-dwelling older adults with and without CVD.
