Sport-specific periodization programs are becoming increasingly popular among youth, collegiate, and professional athletes. These programs aim to systematically, and appropriately, induce training stimuli to optimize fitness gains without inducing a state of overtraining. Technological advances have made it increasingly easy for sport scientists to accurately assess both physiological and mechanical load in training and competition as a means of monitoring acute and chronic load.

PURPOSE: The aim of this study was to examine inflammatory markers and mediators of innate and natural immunity before and after an individualized soccer-specific running program. We hypothesized that our methodological approach to the training periodization would not significantly alter markers of inflammation or immunity between pre- and post-training.

METHODS: Sixteen male athletes completed pre- and post-training measures of fitness (Yo-Yo Intermittent Recovery Test 1; YYIR1), body composition (BodPod), and heart rate variability (HRV) following a six-week training program. Indices of HRV and complexity were assessed during an orthostatic challenge. Fasting blood draws were performed pre- and post-training. A Luminex MAGPIX multiplex reader was used to run a 21-analyte panel of inflammatory and immunological markers. Multivariate equivalence tests were performed using R 3.2.2 to assess similarity.

RESULTS: Training increased YYIR1 scores (18.4%; p<0.001) and a decrease in body adiposity from 11.8% (±3.7) to 9.6% (±2.9) (p=0.001). Significant main effects were reported for HR (p=0.034) and ApEn (p=0.026). HR was significantly reduced in the standing position during post-training measures (p=0.002) while ApEn (p<0.001) was significantly higher. Multivariate equivalence tests indicate similarity between pre- and post-training markers of inflammation and immunity.

CONCLUSION: Our results suggest that an individualized sport-specific training program can significantly improve fitness and athletic performance without adversely affecting innate immunity or the inflammatory response. Concurrent consideration of the results suggests that we were able to optimize training in highly trained collegiate athletes without invoking chronic stress, thus, reducing risk of injury and optimizing performance.
