Research has demonstrated the effects of music on exercise performance such as heart rate, cadence, and rate of perceived exertion. Specifically, music tempo is considered a significant factor influencing physiologic changes and is measured in beats per minute (bpm). The preference for music with fast tempos may be due to a stimulus that increases physiological arousal. However, results have differed depending on population, exercise modality, and experimental protocol. PURPOSE: The purpose of this study was to determine the differences in heart rate and pedal frequency on a cycle ergometer with and without music. METHODS: Participants (N=20) were collegiate level students who were recreationally active and met physical activity standards. Each participant completed two 20 minute cycle sessions, one while listening to a predetermined music playlist and the second without any music. The predetermined music playlist included 4 songs at tempos of 77 bpm, 132 bpm, 82 bpm, and 126 bpm. Participants pedaled at a self-selected frequency. Heart rate and pedal frequency were recorded for each minute of exercise. A paired T-Test was used to determine statistical significance between variables (p<0.05). Analysis of Variance was also used to determine statistical significance between heart rate and music tempo (p<0.05) RESULTS: Results from this study show average heart rate with music at 140 ± 15.7 bpm and without music 130 ± 15.7 bpm. Pedal frequency averaged 62.7 ± 10.7 and 57.8 ± 7.5 revolutions with music and without respectively. There was a statistically significant difference between heart rate (p<0.01) and pedal frequency (p=0.01) from music to no music. A statistically significant difference in heart rate was observed between the music tempo groups, F = 24.51, p = 0.001, with a large effect size, η2 = 0.304. Bonferroni post-hoc tests indicated the heart rates for 77 bpm (126 ± 19), 132 bpm (140 ± 16), and 82 bpm (145 ± 17) was significantly higher than each other (p<0.01). CONCLUSION: The results indicate that music increased heart rate and pedal frequency significantly compared to no music. Additionally, there was a significant difference in music tempo on heart rate. The results from this study support the notion that music does increase physiologic changes during exercise.
