Study Overview
Brief Summary
The overall aim of this project is to compare protein supplementation on performance, recovery, and body composition changes in adolescent soccer players between the whey protein and the control group in response to the 10-12-week intervention.
Detailed Description
Informed Consent, Parental Permission and Assent: These will be obtained over Zoom, prior to participation in any study procedures.
Randomization: Randomization will occur following baseline testing. Participants will be randomized via random number generator stratified by sex, into either the whey protein supplement group or the placebo (isocaloric) control group.
Baseline and Post-Intervention testing will occur over a single day for each participant.
Baseline:
All athletes will report to testing facilities for a single blood draw to measure inflammatory biomarkers and a body composition assessment (via BodPod) to measure fat mass and fat free mass. Participants will then be escorted to a track where they will run a 30-yard dash to assess their speed and a 1.5-mile run to assess their estimated maximal rate of oxygen consumption (VO2max). Participants will then be transferred back to the testing facility where they will undergo assessment of lower body muscle fatigue (via HumacNorm).
