To compare performance and muscle architecture changes in starters and nonstarters during a National Collegiate Athletic Association Division I women's soccer season.

‍

28 females (av. 20 years old) were assessed on NeuroTracker baselines, vertical jump power, repeated line drills and reaction time at preseason, midseason, and postseason. Muscle architecture changes using ultrasonography were assessed at preseason and postseason.

‍

Both starters and non-starters showed similar status or improvements on all assessments across the season, except for line drills performance, which showed greater improvements for starters. NeuroTracker and reaction time performance improved regardless of playtime. Results of muscle architecture analysis indicated that practice training alone provide sufficient stimulus for improving muscle quality during the competitive season. Overall starters did not display significant benefits from competition over athletes who performed training only.

To analyze the repeated effect of stroboscopic vision training on perceptual-cognitive and anticipation skills in soccer players.

‍

28 male soccer players randomized into two groups: Stroboscopic vision training and control groups. The trained group completed 8-weeks of stroboscopic training. Pre post assessments were completed for both groups, which included NeuroTracker baselines and assessments decision-making and anticipation skills.

‍

Both groups improved by similar amounts in NeuroTracker baselines and decision-making. However the trained group showed a larger improvement in anticipation skill than the control group. The findings suggest that stroboscopic vision training does not improve perceptual-cognitive functions or decision-making, but may aid anticipation skills in soccer athletes.

To examine the effects of 14-days ATP supplementation (adenosine 5′-triphosphate) on NeuroTracker visual tracking speed, reaction time, mood and cognition in a double-blind crossover study.

‍

22 adults were randomized to either an active PeakATP® group or a placebo control group and supplemented for 14-days. They then tested on 3 minutes of maximum intensity cycling. Pre, immediately post, and 60-minutes post, all participants completed a NeuroTracker baseline, a visuomotor reaction test (Dynavision D2), a Profile of Mood States Questionnaire and a cognition assessment (ANAM). After another 14 days of no supplementation, the active and control groups were then reversed and the whole procedure was repeated.

‍

NeuroTracker results improved on the second testing procedure, however average differences between active and control groups were negligible. No significant interactions were found on the other assessments, apart from reaction time performance, which improved meaningfully with post ATP supplementation. The results suggest ATP may help decrease fatigue related effects from intense bouts of exercise, but not higher-level cognitive functions.
