Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Sit-to-Stand Chair Test	The change in muscle strength observed in each diet condition will be evaluated through the Sit-To-Stand Chair Test. The number of times a participant comes to a full standing position (from a seated position) in 60 seconds will be recorded.	Weeks 0, 4, 8
Primary	Change in 6-minute walk	The change in muscle strength observed in each diet condition will be evaluated through the 6-Minute-Walk-Test. The distance walked by a participant during the 6 minute test period will be recorded.	Weeks 0, 4, 8
Primary	Retention of Participants	The percentage of randomized participants completing the 16-week diet intervention trial.	Through study completion, approximately 16 weeks
Primary	Adherence to Study Diets	Participant adherence to the study diets will be evaluated.	Through study completion, approximately 16 weeks
Secondary	Change in Lactate	Measures of muscle fatigue will be evaluated through blood biomarkers.	Weeks 0, 4, 8
Secondary	Change in Beta-Alanine	Measures of muscle fatigue will be evaluated through blood biomarkers.	Weeks 0, 4, 8
Secondary	Change in Carnosine	Measures of muscle fatigue will be evaluated through blood biomarkers.	Weeks 0, 4, 8
Secondary	Change in Amino Acids	Measures of muscle fatigue will be evaluated through blood biomarkers.	Weeks 0, 4, 8
