The purpose of this study is to determine the effects of a protein supplementation protocol through a period of muscular disuse in maintaining muscle mass, strength, jump force production, and cross-sectional area in the collegiate population. Two groups of healthy collegiate participants underwent two weeks of unilateral lower limb suspension (ULLS), during which the control group consumed a normal diet and the treatment group received an additional 75 g of protein supplementation. Lean mass, strength, and force production were measured between dietary intakes at baseline and following immobilization. Muscle area was lost between both groups following ULLS (treatment, - 282.8 ± 57.8, p=0.004; control, -349.6 ± 54.8, p=0.001). Between-group analyses did not demonstrate significant results in any of the outcome measures following ULLS; however, there was as trend towards significance in the treatment group of maintaining total lean mass (p=0.08) and leg lean mass (p=0.01) when compared to the control group. Further studies may improve upon the current study design to determine the efficacy of protein supplementation in the active, collegiate population during periods of immobilization with the goal of improving rehabilitation outcomes in this population.
