Enjoyment and affective responses to two regimes of high intensity interval training in inactive women with obesity

This study examined changes in enjoyment, affective valence, and rating of perceived exertion (RPE) in obese women performing two regimes of high intensity interval training (HIIT) differing in structure and volume.
