The purpose of the study was to investigate the effect of vocal and instrumental music on various physiological parameters during submaximal exercise. Each subject underwent three sessions of exercise protocol without music, with vocal music, and instrumental versions of same piece of music. The protocol consisted of 10 min treadmill exercise at 70% HR(max) and 20 min of recovery. Minute to minute heart rate and breath by breath recording of respiratory parameters, rate of energy expenditure and perceived exertion levels were measured. Music, irrespective of the presence or absence of lyrics, enabled the subjects to exercise at a significantly lower heart rate and oxygen consumption, reduced the metabolic cost and perceived exertion levels of exercise (P < 0.05). There was faster recovery of systolic and diastolic blood pressures and exertion levels during the post exercise period. Music having a relaxant effect could have probably increased the parasympathetic activation leading to these effects.
该研究的目的是调查在次最大运动期间声乐和器乐对各种生理参数的影响。每位受试者进行了三个阶段的运动方案，分别是无音乐、有声乐以及同一首乐曲的器乐版本。该方案包括在70%最大心率下进行10分钟的跑步机运动以及20分钟的恢复时间。测量每分钟的心率以及逐次呼吸记录的呼吸参数、能量消耗率和主观用力程度。无论有无歌词，音乐都能使受试者以显著更低的心率和耗氧量进行运动，降低运动的代谢成本和主观用力程度（P<0.05）。在运动后阶段，收缩压和舒张压以及用力程度的恢复更快。具有放松作用的音乐可能增加了副交感神经激活，从而导致了这些效果。
