High intensity interval exercise sessions with interval sets over 3 min may provide superior cardiorespiratory fitness benefits. To our knowledge, the exercise enjoyment of interval sets over 3 min is not yet elucidated. The aim of this study was to examine exercise enjoyment following one session with four intervals of 4 min high intensity exercise (HIIE) versus one session of 45 min moderate intensity continuous exercise (CE) in iso-caloric conditions using a randomized crossover design.
Seven young healthy participants were recruited to undergo two different exercise sessions in a randomized order: (1) 4 × 4 min intervals at >90% of maximum heart rate (HR ) with 3 min of rest between interval sets, and (2) 45 min CE at 70% of HR . Peak oxygen uptake and HR were evaluated prior to the experiment. The participants reported their perceived exercise enjoyment using the 18-item physical activity enjoyment scale (PACES) questionnaire and their rating of perceived exertion (RPE) using Borg's 6-20 scale.
There was no difference in the PACES score between the high intensity interval exercise session [median: 95.5 (inter-quartile range: 21.8)] and the moderate intensity CE session [91.0 (13.5), = 0.36, = -0.22]. The participants reported a higher RPE in the high intensity interval exercise session [16.5 (2.0)] compared with the CE session [9.0 (2.0), = 0.01, = -0.88].
Similar exercise enjoyment was reported following four high intensity intervals of 4 min compared with a moderate intensity CE session in this randomized crossover study with iso-caloric conditions. If enjoyment is a mediating factor for engaging in exercise, one should expect a similar probability of exercise adherence following high intensity 4 min intervals and continuous moderate intensity exercise when prescribing aerobic exercise as preventive medicine.
包含时长超过3分钟的间歇组的高强度间歇训练可能会带来更显著的心肺适能益处。据我们所知，时长超过3分钟的间歇组训练的运动愉悦感尚未得到阐明。本研究的目的是采用随机交叉设计，在等热量条件下，比较一次包含四个4分钟高强度运动（HIIE）间歇组的训练与一次45分钟中等强度持续运动（CE）后的运动愉悦感。
招募了七名年轻健康的参与者，让他们以随机顺序进行两种不同的训练：（1）以超过最大心率（HR）90%的强度进行4组4分钟的训练，组间休息3分钟；（2）以HR的70%的强度进行45分钟的持续运动。在实验前评估峰值摄氧量和HR。参与者使用18项体育活动愉悦感量表（PACES）问卷报告他们的运动愉悦感，并使用Borg的6 - 20量表报告他们的主观用力程度（RPE）。
高强度间歇训练组的PACES得分[中位数：95.5（四分位间距：21.8）]与中等强度持续运动组[91.0（13.5）]之间没有差异，P = 0.36，效应量 = -0.22。与持续运动组[9.0（2.0）]相比，参与者报告在高强度间歇训练组中的主观用力程度更高[16.5（2.0）]，P = 0.01，效应量 = -0.88。
在这项等热量条件下的随机交叉研究中，与中等强度持续运动组相比，在进行四个4分钟的高强度间歇训练后，报告的运动愉悦感相似。如果愉悦感是参与运动的一个中介因素，那么在将有氧运动作为预防医学手段进行处方时，高强度4分钟间歇训练和持续中等强度运动后的运动坚持概率应该相似。
