简要总结
High-intensity interval exercise (HIIT), as compared to moderate intensity continuous training (MICT), is a time-efficient strategy to decrease total and abdominal fat mass (FM). However, the mechanisms underlying such adaptations are not yet elucidated and research are still needed to establish the optimal HIIT according to subject characteristics. The aim of this study was to compare acute HIIE and MICE cycling exercises on enjoyment, post-exercise substrate oxidation, appetite and energy intakes over 24h in postmenopausal women with overweight or obesity. It is hypothesized that compared with the traditional MICE, HIIE could favor greater enjoyment, higher 2h-post-exercise fat oxidation and a similar energy intakes over 24h despite different post-exercise appetite perceptions.
详细描述
The aim of this study was to compare acute HIIE and MICE cycling exercises on enjoyment, post-exercise substrate oxidation, and appetite and energy intakes over 24h in postmenopausal women with overweight or obesity.
Using a randomized crossover design, 12 postmenopausal women completed 3 cycling exercises at 6-days intervals:
i) Moderate Intensity Continuous Exercise (MICE) which consisted of 35 min cycling at 60-65% theorical Peak Heart Rate (thPHR) ii) High Intensity Interval Exercise 1 (HIIE 1) 60 cycles of speeding up for 8 s at 80-90%thPHR followed by pedaling slowly for 12 s (20min) iii) High Intensity Interval Exercise 2 (HIIE 2) which consisted of repeated 10 x 1min at 80-90% thPHR followed by pedaling slowly for 1min.
Substrate oxidation (CHO and FAT) were measured at rest and 2h- post exercise. Enjoyment, perceived exertion and appetite were recorded and post-exercise energy intakes were assessed over 24h.
