Athlete and (a type of supplement) - Essay Example The study aimed to asses the effect of these on strength, body composition, and plasma glutamine levels during a 10 week, supervised resistance training program. The results revealed that there was no change in plasma glutamine levels in either group. The group, which received whey isolate, showed a significantly greater gain in lean mass, change in fat mass and improvements in strength, when compared to the group, which received casein. Burke et al., 2001, assessed the muscular adaptations, which occurred in 36 males randomly assigned to supplementation with whey protein alone, whey protein and creatine monohydrate, or placebo. The results indicated that the group, which supplemented with whey protein, had greater improvement in knee extension peak torque and lean tissue mass than those who trained with placebo. Those who supplemented with a combination of whey protein and creatine had greater increases in lean tissue mass and bench press than those who supplemented with only whey protein or placebo. However, it was noted that not all strength measures were improved with supplementation; the group who supplemented with creatine and/or whey protein and the placebo group had similar increases in squat strength and knee flexion peak torque. Cribb et al., 2007, aimed to examine the effects of whey protein (WP) and creatine monohydrate (CrM) (both separately and in combination), on body composition, muscle strength, fiber-specific hypertrophy (i.e., type I, IIa, IIx), and contractile protein accrual during a 11-week structured, supervised RE program. This was a double-blind randomized study involving resistance-trained males placed into one of the four groups: creatine/carbohydrate (CrCHO), creatine/whey protein (CrWP), whey protein (WP) only, or carbohydrate only (CHO). Assessments (completed the week before and after the RE program) included strength (1RM, three exercises), body composition (DEXA), and vastus lateralis
