Brief Summary
The objective of this project is to determine the effect of 9 months of progressive resistance training with daily whey protein supplements on the body composition (changes in muscle and fat) in young adults. The investigators hypothesize that those individuals who receive whey protein supplements will have larger gains in muscle and larger losses of fat tissue in response to resistance training compared to those who receive supplements of soy or carbohydrate.
