Clinical Trial Summary

The chronic phase of the study will evaluate the effects of pre-exercise and post-exercise ingestion of a multi-ingredient supplement on adaptations to a 6-week exercise program consisting of both resistance training and high intensity aerobic exercise, using a randomized, double-blind, placebo-controlled design. Participants will complete an enrollment/familiarization visit, a baseline testing session, followed by a 6-week supervised exercise intervention, and post-testing session identical to baseline testing. Participants will be randomized during the baseline session to groups receiving either 1) Active Treatment (pre-post supplementation), 2) placebo (noncaloric beverage), or 3) control, not participating in exercise or consuming a treatment. During the supervised 6-week resistance training program, participants will complete a moderate-intensity warm-up, a full-body resistance training workout (2 x per week) and an interval training session (1 x per week). Thirty-minutes prior to each training session, and within 15 minutes post-exercise, participants will consume their randomly assigned treatment beverage. Body composition, blood markers of muscle damage/recovery, strength, and performance tests will be measured before (baseline) and after training (Post) to evaluate the effects of supplementation. All data collection will be conducted by the Principal Investigator and Research Assistants. All subjects will report to the Applied Physiology Laboratory and Human Performance Center in Fetzer Hall for all testing and training sessions, which will span approximately 8 weeks.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Strength	Change from baseline in strength by measuring 1 repetition maximum for leg press and bench press	baseline, week 8
Secondary	Muscle soreness	Change from baseline on muscle soreness using visual analog scale (a horizontal 100 mm line where zero will represent no soreness and one-hundred will represent maximum amount of soreness. Participants will be asked to place a single vertical that represents their current soreness. The scale will be measured with a calibrated ruler with the higher numbers representing more soreness.)	baseline, week 8
Secondary	Recovery	Change from baseline on muscle damage by measuring creatine kinase and isoprostanes	baseline, week 8
Secondary	Training Volume	Change from baseline in total training volume measured by product of sets x repetitions completed x external load used in exercise routine	baseline, week 8
Secondary	Performance	Change from baseline on performance by measuring countermovement vertical jump	baseline, week 8
Secondary	Body Composition	Change from baseline in body composition using DXA measurements fat mass (kg) and lean mass (kg)	baseline, week 8
