Study 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.

Primary Outcome

Oxygen consumption was assessed via high-resolution mitochondrial respirometry in permeabilized skeletal muscle. This outcome was assessed via 2 different protocols; Protocol 1 was a substrate-uncoupler-inhibitor titration (SUIT) and Protocol 2 was an adenosine diphosphate (ADP) titration. These data are reported as the percent change from baseline compared to 12 weeks.
