Resistance Exercise, Metabolism and Time of Day

The Impact of the Time of Day on Metabolic Responses to Resistance Exercise in Adults Who Are Obese or Overweight: a Randomised Controlled Trial

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

Inclusion Criteria:

• pass the physical activity readiness questionnaire
• body mass index (BMI) >27kg/m² and limited to 40 kg/m².

Exclusion Criteria:

• Prior surgery for weight loss
• Prior history of heart, lung, cancer, endocrine or liver disease
• Participating in more than 1 hour structured exercise training per week
