Summary

The purpose of this study is to investigate the effects of a single session of at-home bodyweight interval exercise, performed in the fasted or fed state, on postprandial glycemic management, post-exercise fat oxidation, and overall perceptions of appetite in recreationally active females. This is a remote/online study and does not involve any visits to the laboratory.

Detailed description

Following the acquisition of informed consent via videoconferencing, eligibility to participate in the study will be determined using questionnaires. If inclusion criteria is met, participants will undergo virtual exercise familiarization by following a pre-recorded instructional video. Eligible participants will be assigned, in a random order, to two metabolic trials at least 3 days apart in the follicular phase of the same menstrual cycle. These visits will be online with an investigator on videoconferencing. The two trials involve: 1) Exercise followed by breakfast; and 2) Breakfast followed by exercise. Various outcomes will be measured throughout the metabolic trials including: blood sugar, fat oxidation and appetite. All research tools needed to acquire these methods will be delivered to participants' place of residence.
