Listening to music while working out measurably improves physical performance.
Listening to music while exercising doesn't just relieve boredom — it can help improve the quality of your workout by increasing your stamina and putting you in a better mood.
In particular, music that is motivational or synchronized with your exercise is shown to have physical and psychological effects. When a song has a strong, steady beat, for example, you can pedal or run to the beat of that music, which tends to feel satisfying and may inspire you to exercise more. The lyrics or catchy rhythm of motivational music inspires you to exercise longer or work harder during your exercise routine.
Studies show that faster-paced music tends to help improve athletic performance when a person engages in low-to-moderate level exercise, either by increasing distance traveled, pace, or repetitions completed. For example, a 2006 study that looked at the effect of music on the selection of treadmill speed found that while listening to fast-paced music, participants increased their pace and distance traveled without becoming more tired. Other studies drew similar conclusions, suggesting that listening to music with more beats per minute can enhance physical performance during low-to-moderate level exercise.
Several studies have shown how the exact tempo, as measured in beats per minute, affects one's level of exercise. These studies determined that the ideal tempo necessary for maximum performance depends on the type of exercise. A 2011 study showed that in order to achieve the best performance for cycling (which was calculated by measuring exercise intensity through heart rate), the preferred tempo is between 125 and 140 beats per minute. A study published in 2014 showed that the best music tempo for enhanced performance on the treadmill is between 123 and 131 bpm. A plausible reason for why different types of exercise have different ideal tempos is related to one's ability to keep time with the beat of the music, synchronizing strides, or pedaling to the beat of the music. Since pace differs on the treadmill versus the exercise bike or elliptical, music of different tempos is needed to achieve ideal performance for various workouts.
Researchers have recently begun to pursue more detailed explanations as to why music can improve exercise performance. A 2010 study led by sports psychologist C.I. Karageorghis states that music can improve athletic performance in two ways: it can either delay fatigue or increase work capacity. According to this study, the effects of music lead to "higher-than-expected levels of endurance, power, productivity, or strength."
North and Hargreaves suggest that music distracts from pain endured during exercise through competing for sensory stimuli because it is easier to forget about pain or fatigue when a song you enjoy is distracting you.
