Summary

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

Conditions

• Metabolic Disease

Interventions

Type	Name	Description
BEHAVIORAL	Exercise training	Exercise will consist of 1 set x 9 exercises x 3 sessions per week x 6 weeks. The load to be used during training will be calculated as 80% of one-repetition maximum (1RM) with each set performed to failure. 1RM will be re-tested on week 3, and the load adjusted accordingly, and upon completion of the study. During the training period, all sessions of training will be supervised by the researcher. The following exercises will be performed: Bench press, biceps curl, lat pull down, overhead press, lateral raise, leg extension, leg curl and calf raise.
