Abstract

Purpose: Research shows the benefits of whey isolate protein powder and casein protein powder supplementation in regard to body composition and resting metabolic rate; however, minimal research exists comparing the effectiveness of whey to casein supplementation. Methods: Eighteen (18) physically trained, healthy individuals (23±3.1 yrs.; 171.7cm; 12 males; 6 females) completed a randomized two condition [Combat 100% Isolate (Whey) versus Combat 100% (Casein)] by two time point [Pre-, Post-] intervention. The intervention consisted of subjects supplementing on either whey or casein in conjunction with resistance training over an 8-week period. Pre and post testing included % body fat and metabolic rate. Results: A 2x2, repeated-measures analysis of variance (ANOVA) demonstrated non-significant (p ≥ 0.05) effects on changes in % body fat and resting metabolic rate following the 8-week intervention. Conclusions: The data concludes no differences in the effects of whey versus casein protein supplementation in physically active, healthy individuals
