The purpose of this study is to investigate the effects of music tempo on heart rate (HR), HR variability (HRV), lactate levels, and aerobic capacity during walking exercise in male college students. Ten male college students randomly participated in three experiments using various music tempos on a treadmill device to prevent data contamination between measurements by allowing a 2-week interval. Walking exercise was performed at a moderate intensity of 60%-70% maximum HR for 30 min, with participants divided into three groups based on music tempo: exercise group with fast tempo music (ExF, 120-160 bpm), exercise group with slow tempo music (ExS, 60-70 bpm), and exercise group without music (Ex). The study was designed using a randomized crossover method. Two-way repeated measures analysis of variance (ANOVA) assessed group-by-time interactions, and one-way ANOVA was used to compare differences between groups. analysis was performed using Tukey honestly significant difference. As a result, the ExF group had higher HR, ventilation, metabolic equivalent, and oxygen up-take during treadmill exercise than the ExS or Ex group. But there was no significant interaction of HR and HRV during recovery according to music tempo. HRV was significantly higher in the ExF group during exercise when compared to other groups. Blood lactate concentration was significantly decreased in the ExS group. These findings provide new information that music tempo type applied during treadmill exercise might have a positive effect on the maximum oxygen intake and lactate accumulation in the recovery phase.
本研究旨在调查音乐节奏对男性大学生步行运动期间心率（HR）、心率变异性（HRV）、乳酸水平和有氧能力的影响。十名男性大学生随机参与了三项实验，在跑步机设备上使用不同的音乐节奏，并设置两周的间隔期以防止测量之间的数据污染。步行运动以最大心率的60%-70%的中等强度进行30分钟，参与者根据音乐节奏分为三组：快节奏音乐运动组（ExF，120-160次/分钟）、慢节奏音乐运动组（ExS，60-70次/分钟）和无音乐运动组（Ex）。该研究采用随机交叉设计方法。双向重复测量方差分析（ANOVA）评估组间与时间的交互作用，单向ANOVA用于比较组间差异。使用Tukey真实显著差异进行分析。结果显示，在跑步机运动期间，ExF组的心率、通气量、代谢当量和摄氧量均高于ExS组或Ex组。但在恢复过程中，根据音乐节奏，心率和心率变异性没有显著的交互作用。与其他组相比，ExF组在运动期间的心率变异性显著更高。ExS组的血乳酸浓度显著降低。这些发现提供了新的信息，即在跑步机运动期间应用的音乐节奏类型可能对恢复阶段的最大摄氧量和乳酸积累有积极影响。
