Trial overview
Official title: A randomized, double-blind, placebo-controlled, three-arm trial to evaluate the effect of using whey protein and creatine supplements on muscular strength in weight-training adult males
Trial description: The purpose of this study was to evaluate the effect of combined whey protein and creatine supplement, as compared with whey protein supplement alone, on change in upper and lower body strength.
Primary purpose:
Basic Science
Trial design:
Parallel Assignment
Masking:
Triple (Participant, Care Provider, Investigator)
Allocation:
Randomized
Primary outcomes:
To evaluate the effect of combined whey protein and creatine supplement, as compared with whey protein supplement alone, on change in upper body strength from Baseline to Week 4.
Timeframe: Baseline, Week 2, 4, 8 and 12
Secondary outcomes:
To evaluate the effect of combined whey protein and creatine supplement, as compared with whey protein supplement alone, on changes in upper and lower body strength from Baseline through Week 12
Timeframe: Baseline, Week 2, 4, 8 and 12
To evaluate the effect of combined whey protein and creatine supplement, as compared with placebo, on changes in upper and lower body strength from Baseline through Week 12.
Timeframe: Baseline, Week 2, 4, 8 and 12
To compare changes in upper and lower body strength from Baseline through Week 12, between combined whey protein and creatine supplement, whey protein supplement alone, and placebo.
Timeframe: Baseline, Week 2, 4, 8 and 12
To compare changes in upper and lower body endurance from Baseline through Week 12, between combined whey protein and creatine supplement, whey protein supplement alone, and placebo.
Timeframe: Baseline, Week 2, 4, 8 and 12
To compare the changes in lean vs. fat body mass composition from Baseline to Week 12 between combined whey protein and creatine supplement, whey protein supplement alone, and placebo.
