Inclusion Criteria * Being physically inactive (not doing at least 150 minutes/week of structured exercise). * Being sedentary (having a daily sedentary time/day for \>7 hours). * Having a BMI between 25 and 29.9 kg/m2. * Having a history of regular menstrual cycles for female participants. * Having medical examination approval. Exclusion Criteria * Taking any acute or chronic medication or supplement that may affect metabolism. * Having an acute or chronic illness that limits exercise (musculoskeletal problems, cardiovascular disorders, respiratory problems, etc.). * Consuming tobacco products. * Meeting 3 or more of the metabolic syndrome criteria (waist circumference of 102 cm or more in men, 88 cm or more in women, triglyceride level of 150 mg/dL or higher, HDL cholesterol level below 40 mg/dL in men and 50 mg/dL in women, blood pressure of 130/85 mmHg or higher, fasting blood glucose level of 100 mg/dL (5.6 mg/L) or higher).
What this study is about
In the sponsor’s own words, from the registry.
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.
