Effects of Omega-3 and Whey Protein Supplementation on Lean Mass in Older Adults
Study Details
Study Description
Brief Summary
To evaluate the effect of omega-3 supplementation combined with whey protein intake on lean mass and strength gains in older adults performing resistance exercise. Participants will be randomized into the 4 groups. The placebo group will receive 4 g per day of corn oil and 40 g per day of maltodextrin. The omega 3 + placebo group will receive 4 g per day of fish oil and 40 g per day of maltodextrin. The whey protein + placebo group will receive 40g per day of whey and 4g per day of corn oil. The omega 3 + whey group will receive 4g per day of fish oil and 40g per day of protein. All will perform the same exercise protocol for 12 weeks
