结局指标
主要结局
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.
时间窗: Baseline, Week 2, 4, 8 and 12
Body strength will be evaluated using Repetition maximum (1-RM) and bench and leg press exercise testing. 1-RM in weight training is the maximum amount of weight one can lift in a single repetition for a given exercise
次要结局
- 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.(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.(Baseline and Week 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.(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.(Baseline, Week 2, 4, 8 and 12)
- 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(Baseline, Week 2, 4, 8 and 12)
