Summary

This study compares aerobic exercise training performed before breakfast (i.e., in the fasted state) to similar training performed after breakfast in people with type 1 diabetes. Training will take place over 12 weeks.

Conditions

  • Diabetes Mellitus, Type 1

Interventions

BEHAVIORAL

Fasted Exercise

Participants will complete three sessions of combined resistance-aerobic exercise per week. Sessions will always start with resistance training followed by aerobic training, and will increase in duration throughout the intervention period, so that by the final three weeks of the intervention, all participants accumulate 150 minutes per week of moderate intensity aerobic exercise and 75 minutes of resistance exercise per week. Participants will complete three distinct resistance exercise sessions per week, which will increase in load, but decrease in repetition range throughout the trial. The aerobic component of the exercise sessions will increase in duration from 35 to 50 minutes per session. Participants will walk on a treadmill at a speed and incline that corresponds to 70-80% of ventilatory threshold.

BEHAVIORAL

Postprandial Exercise

Participants will complete three sessions of combined resistance-aerobic exercise per week. Sessions will always start with resistance training followed by aerobic training, and will increase in duration throughout the intervention period, so that by the final three weeks of the intervention, all participants accumulate 150 minutes per week of moderate intensity aerobic exercise and 75 minutes of resistance exercise per week. Participants will complete three distinct resistance exercise sessions per week, which will increase in load, but decrease in repetition range throughout the trial. The aerobic component of the exercise sessions will increase in duration from 35 to 50 minutes per session. Participants will walk on a treadmill at a speed and incline that corresponds to 70-80% of ventilatory threshold.
