Summary

The purpose of this study is twofold: (1) to determine whether breaking up prolonged sitting with aerobic or sprint cycling breaks reduces postprandial blood glucose, insulin, CRP, and blood pressure, which are established risk markers for cardiometabolic diseases; and (2) to assess substrate oxidation during this period in order to identify which exercise condition promotes the greatest increase in fat oxidation.

Conditions

  • Cardiovascular Risk Markers
  • Substrate Oxidation
  • Postprandial Metabolism
  • Exercise Physiology

Interventions

OTHER

Aerobic Exercise Intervention

In the aerobic exercise condition, participants will perform 2 minutes of moderate-intensity continuous cycling.

OTHER

Sprint Exercise Intervention

In the sprint condition, participants will complete a 10-second all-out sprint, as determined during the preliminary test.

OTHER

Sedentary Behaviour Intervention

Participants will remain seated for a total duration of 7 hours. During this period, they will be instructed to minimize excessive movement and will only be permitted to rise from the chair for voiding purposes.
