When It HIITs, You Feel No Pain: Psychological and Psychophysiological Effects of Respite-Active Music in High-Intensity Interval Training.

ABSTRACT

The authors investigated the effects of respite-active music (i.e., music used for active recovery in between high-intensity exercise bouts) on psychological and psychophysiological outcomes. Participants (N = 24) made four laboratory visits for a habituation, medium- and fast-tempo music conditions, and a no-music control. A high-intensity interval-training protocol comprising 8 × 60-s exercise bouts at 100% Wmax with 90-s active recovery was administered. Measures were taken at the end of exercise bouts and recovery periods (rating of perceived exertion [RPE], state attention, and core affect) and then upon cessation of the protocol (enjoyment and remembered pleasure). Heart rate was measured throughout. Medium-tempo music enhanced affective valence during exercise and recovery, while both music conditions increased dissociation (only during recovery), enjoyment, and remembered pleasure relative to control. Medium-tempo music lowered RPE relative to control, but the heart rate results were inconclusive. As predicted, medium-tempo music, in particular, had a meaningful effect on a range of psychological outcomes.
