Milk Protein Feeding After Aerobic Exercise in Older Adults With Pre-diabetes Taking the Biguanide Metformin

Participant gender:
All
Summary
The investigators propose that post-exercise milk protein feeding will enhance the mitochondrial protein synthesis (biogenesis) response to an exercise-training program. In addition, the investigators propose that this stimulatory effect of protein feeding will overcome the potential blunting effect of metformin on exercise responses. The investigators will investigate these outcomes over a 12-week exercise-training program in older adults with pre-diabetes with or without metformin treatment.
