About

The aim of the current study is to determine the effect of time of day on the muscle and metabolic responses to resistance exercises in obese or overweight adults. To achieve this aim we have the following objectives:

1. Compare the effects of resistance exercise training performed in the morning vs the evening on insulin sensitivity
2. Compare the effects of resistance exercise training performed in the morning vs the evening on gains in muscle mass and strength
3. Compare the acute glucose responses to resistance exercise performed in the morning vs the evening
