High-intensity interval training (HIIT) is highly beneficial for health and fitness and is well tolerated. Treadmill-based HIIT normally includes running interspersed with walking. The purpose of this study was to compare ungraded running and graded walking HIIT on perceived exertion, affective valence, and enjoyment. Thirty-four active, healthy adults completed maximal testing and two 20-min HIIT trials alternating between 85% of VO2peak and a comfortable walking speed. Affective valence, enjoyment, and perceived exertion, both overall (ratings of perceived exertion [RPE]-O) and legs only (RPE-L), were measured. RPE-O and affective valence were similar between HIIT trials (p > .05), RPE-L was higher for walk HIIT (p < .05), and enjoyment was higher for run HIIT (p < .05). Findings indicate that both walk and run HIIT produce exertion, affective, and enjoyment responses that are positive and possibly supportive of exercise behavior. Walk HIIT may be desirable for individuals who are unable or do not want to run.

高强度间歇训练的心理反应:等效代谢负荷下分级步行和不分级跑步的比较。

高强度间歇训练 (HIIT) 对健康和健身非常有益,并且耐受性良好。基于跑步机的 HIIT 通常包括跑步和步行。本研究的目的是比较不分级跑步和分级步行 HIIT 对感知用力、情感效价和享受的影响。34 名活跃的健康成年人完成了极限测试和两项 20 分钟 HIIT 试验,交替使用 85% 的 VO2peak 和舒适的步行速度。测量了总体(感知用力评分[RPE]-O)和仅腿部(RPE-L)的情感效价、享受和感知用力。HIIT 试验之间的 RPE-O 和情感效价相似 (p > .05),步行 HIIT 的 RPE-L 较高 (p < .05),跑步 HIIT 的享受度较高 (p < .05)。研究结果表明,步行和跑步 HIIT 都会产生积极的、可能支持锻炼行为的努力、情感和享受反应。对于无法或不想跑步的人来说,步行 HIIT 可能是理想的选择。
