OBJECTIVES: To compare the affective responses and enjoyments to acute high-intensity training (HIIT) with short or long intervals in young and obese females.
METHODS: Participants completed two bouts of HIIT which were separated over 48 hours respectively. The exercise protocols were cycling on an ergometer at 90%VO2peak intensity for 4 minutes with 3 minutes recovery(Low-frequency interval, Group L) or 40 seconds cycling with 30 seconds recovery (High-frequency interval, Group H) until 200 KJ mechanical work was completed. At the time of 0%, 25%, 50%, 75% and 100% work was completed, the feeling scale (FS), rating of perceived exertion (RPE) were recorded, and the blood lactic acids (LA) were measured when the 50% and 100% work was completed. The physical activity enjoyment scale (PAES) was recorded 5 minutes after the exercise.
RESULTS: Before the exercise, there were no significant differences between the group H and L in terms of the HR, RPE, FS and LA. When 25%, 50%, 75% and 100% of work was completed, the HR and the RPE in group H were all lower than the corresponding time point in group L. The LA in group H was lower than the corresponding values in group L when 50% and 100% work was completed. At the time of 75% and 100% work was completed, the FS in group H was higher than group L, although there were no significant differences at the time of 25% and 50% work done between the two groups. By the end of exercise, the PAES score in group H was higher than group L.
CONCLUSIONS: Increasing the frequency of interval could increase the positive feeling during HIIT and improve the physical activity enjoyment.
