Music is used to distract, energize, and entertain during exercise by producing positive psychological and physiological responses. Specifically, listening to music during exercise enhances performance, increases motivation, improves affect, and optimizes arousal. Researchers have identified several elements of music that may moderate this relationship, including lyrics. However, few studies to date have examined the influence of motivational lyrics on psychological and physiological states during exercise. Thus, the primary purpose was to investigate the effects of lyrics in music on motivation, affect, arousal, and perceived exertion during moderate intensity cycling. Thirty (Mage = 21.0 ± 2.9 years old) college-aged individuals performed three, 8-min acute bouts of moderate-intensity exercise on a cycle ergometer during music with lyrics (ML), music without lyrics (MNL), and no music control (MC) conditions. Measures of motivation, affect, arousal, and perceived exertion were taken before and after a 6-min warm-up, every 2-min during the exercise bout, and following a 2-min cool-down. For ML and MNL conditions, participants reported higher motivation, affect, and arousal during exercise relative to the MC condition. As expected, RPE increased throughout the exercise period, with no condition differences observed. Additionally, there were no differences in responses between the ML and MNL conditions. Collectively, these results suggest that music, regardless of lyrical content, can enhance psychological responses during exercise. The current findings may help address common exercise barriers and inform exercise practitioners on music selection to improve exercise adherence.
