The Effects of High Intensity Interval Exercise in Obese

In the HIIE 1 session, all the subjects performed 10 stimuli of 1 min at high intensity (92% of VO2Max) with passive recovery (without exercise) of 1 min.

In the HIIE 3 session, the subjects performed the same stimulus of the HIIE1, but with passive recovery of 3 min. Both protocols started with a warm-up of 5 min at 50% of the VO2Peak performed on a T2-100 GE Healthcare® treadmill (Lynn Medical, Wixon, Michigan, USA).

In the control session, participants remained seated for 30 min. During HIIE 1 and 2, HR and RPE were assessed immediately after stimulus intervals (ten measurements at each HIIE). In all sessions, the subjects remained in supine position to obtain hemodynamic measurements which were obtained before and at 10 min, 30 min and 60 min after the HIIE and control sessions.
