Psychophysiological effects of music on acute recovery from high-intensity interval training

Abstract

Numerous studies have examined the multifarious effects of music applied during exercise but few have assessed the efficacy of music as an aid to recovery. Music might facilitate physiological recovery via the entrainment of respiratory rhythms with music tempo. High-intensity exercise training is not typically associated with positive affective responses, and methods of assuaging this warrant further exploration. This study assessed the psychophysiological effects of music on acute recovery and prevalence of entrainment in-between bouts of high-intensity exercise. Thirteen male runners (Mage=20.2±1.9years; BMI=21.7±1.7; V̇O2 max=61.6±6.1ml·kg·min-1) completed three exercise sessions comprising 5×5-min bouts of high-intensity intervals interspersed with a 3-min passive recovery period. During recovery, participants were administered positively-valenced music of a slow-tempo (55-65bpm), fast-tempo (125-135bpm), or a no-music control. A range of measures including affective responses, RPE, cardiorespiratory indices (gas exchange and pulmonary ventilation), and music tempo-respiratory entrainment were recorded during exercise and recovery. Fast-tempo, positively-valenced music resulted in higher Feeling Scale scores throughout recovery periods (p<0.01, ηp2=0.38). There were significant differences in HR during initial recovery periods (p<0.05, ηp2=0.16), but no other music-moderated differences in cardiorespiratory responses. In conclusion, fast-tempo, positively-valenced music applied during recovery periods engenders a more pleasant experience. However, there is limited evidence that music expedites cardiorespiratory recovery in-between bouts of high-intensity exercise. These findings have implications for athletic training strategies and individuals seeking to make high-intensity exercise sessions more pleasant.
