A common barrier to exercise is "lack of time". Accordingly, interest in low-volume, high-intensity training has grown exponentially since this activity is considered time-efficient. However, the high-intensity nature of this exercise may frequently result in feelings of displeasure creating another barrier for many people. The purpose of this study was to compare affective (pleasure-displeasure) responses to three low-volume, high-intensity exercise conditions, including a novel shortened-sprint protocol. Using a within-subjects, randomised crossover experiment, healthy participants ( = 36) undertook a single bout of: 1) traditional reduced-exertion, high-intensity interval training (TREHIT), 2) a novel, shortened-sprint REHIT (SSREHIT) protocol, and 3) sprint continuous training (SCT). Affect and perceived efforts were recorded throughout exercise using the Feeling Scale (FS) and the 15-point Borg Rating of Perceived Exertion (RPE) scale, respectively. Enjoyment was recorded 5 min post-exercise using the Exercise Enjoyment Scale (EES). Differences were found for FS (condition by time interaction: = 0.01, = 0.26), RPE ( = 0.01, = 0.23), and enjoyment ( < 0.01) with all outcomes favouring SSREHIT. Shortened-sprint protocols may diminish feelings of displeasure and might be a time-efficient yet tolerable exercise choice to help motivate some people to increase their physical activity and fitness.
锻炼的一个常见障碍是“缺乏时间”。因此，自从这种活动被认为是高效省时的，人们对低容量、高强度训练的兴趣呈指数级增长。然而，这种运动的高强度性质可能经常导致不愉快的感觉，这对许多人来说是另一个障碍。本研究的目的是比较三种低容量、高强度运动条件（包括一种新的缩短冲刺方案）的情感（愉快-不愉快）反应。使用单因素、随机交叉实验，健康参与者（n=36）进行了单次以下三种运动之一：1）传统低强度、高强度间歇训练（TREHIT），2）新的缩短冲刺 REHIT（SSREHIT）方案，和 3）冲刺连续训练（SCT）。使用感觉量表（FS）和 15 点 Borg 感知用力等级（RPE）量表分别在运动过程中记录情感和感知用力。运动后 5 分钟使用运动享受量表（EES）记录运动享受程度。FS（条件与时间交互：p=0.01，ηp2=0.26）、RPE（p=0.01，ηp2=0.23）和运动享受（p<0.01）存在差异，所有结果均有利于 SSREHIT。缩短冲刺方案可能会减少不愉快的感觉，并且可能是一种高效且可耐受的运动选择，可以帮助激发一些人增加他们的体育活动和健康。
