The Impact of Beef on Muscle Fatigue in Older Adults

Study overview

The goal of this controlled-feeding cross-over diet intervention is to compare a beef diet to a vegetarian diet on muscle fatigue in older adults. The aims are: AIM 1: To test the hypothesis that muscle fatigue is attenuated in older adults consuming beef compared to older adults consuming a plant-based diet. AIM2: To test the hypothesis that daily beef consumption improves biochemical indicators related to muscle fatigue. Participants will be randomized to consume either a beef-based diet or vegetarian diet under controlled-feeding conditions for 8 weeks. After a 2-week washout period, participants will cross-over to consume either the beef diet or vegetarian diet for 8 weeks. Body composition and functional muscle outcomes will be measured during each 8-week feeding period. Blood samples will also be collected.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
