Methods

Music Tempo & Heart Rate (HR)Waterhouse and colleagues4 found that one’s heart rate was affected by the tempo of the music they were listening to while performing a cycling task. An increase in music tempo (10%) resulted in an increased HR, while a decreased tempo (10%) resulted in a lowering of HR. However, HR increased significantly when music tempo was higher, whether it was the song’s actual tempo or the track’s tempo was artificially increased. In a more recent study, the opposite was found where those that listened to slow/soft music actually had a higher HR. The research found that soft/slow music lowers arousal physiologically during submaximal exercise, thus increasing performance and HR1.

In the current society, health and fitness are at an all-time premium3.

Large amounts of money are being spent on shoes, supplements, and other training aids that are proposed to improve performance. However, one training tool that many swear by and cannot do without is music. Can music affect one’s performance? A number of studies have been performed to determine music’s influence on the body and mind.

Music Tempo & Perception of ExertionMusic tempo has also been shown to affect the level of effort that one believes they are putting forth. Yamashita and colleagues5 found that when performing a cycle ergometer task at a 40% max level (low intensity), those listening to music were found to have a lower perception of effort (i.e., believed the task to be easier) than those without music. However, this effect was not found when participants performed at a higher intensity (60%).

Time EstimationOne hypothesis for why music may play a role in physical performance is that it may distract you from the task. The cognitive-time model suggests that the more information processing that is required, the more the internal cognitive timer is distracted2. According to Sucala, as the information load increases (as with the addition of music), the timer becomes distracted, and we are less able to keep up with time2. This distraction could be beneficial to someone performing a tedious exercise task.

Experimental Paradigm & Time EstimationTime estimation is experimentally studied using two main paradigms, retrospective and prospective. In the prospective paradigm, participants are informed in advance that they will be asked to make judgments regarding the perceived duration of elapsed time. In the retrospective paradigm, participants are asked their perceptions of elapsed time without advance notice6.

To determine whether music tempo and/or experimental paradigm (prospective or retrospective) affect HR, perception of fatigue, and

perception of time (time estimation) in a physical task.

Participants: 24 healthy volunteers (12 male, 12 female), ranging 18-51 years of age

The following steps were followed for each trial (repeated 3 times):1. Check HR (trial did not begin until HR returned to resting/baseline)2. Instructions (based on paradigm):

a. Prospective: Participants informed that after the trial, they would be asked to estimate how long the trial lasted

b. Retrospective:i. 1st trial – Given no prior information/instructionsii. 2nd or 3rd trial – Participants informed that they would be asked to provide their

motivation level following the trial3. Participants instructed to pedal at a comfortable rate for the duration of the trial, and music started

(headphones).4. Recorded distance person pedaled, RPM & HR at specific time, and RPE (every 3 minutes)5. Follow up questions

There has been a great deal of value placed on physical performance in recent years, with athletes searching for anything that will give them a competitive advantage, and the “weekend warrior” looking for ways to improve their health/fitness.3 Music has become a popular strategy in both arenas. However, given the various dimensions of music (e.g., tempo, volume, genre), it has been difficult to determine what aspects of music, if any, affect performance. Previous research has shown a connection between music tempo and performance4, but further examination is needed to determine the extent/cause of that relationship. Purpose: The purpose of this study is to examine the effect that music tempo has on task performance, HR, and perceptions (i.e., fatigue and time estimation) in either a retrospective or prospective testing design. Methods: Participants were asked to perform three bouts of a cycling task, while listening to no music, slow music, or fast tempo music. Participants’ heart rate, speed, and perceptions of exertion were recorded within each condition. In addition, participants were asked to estimate the amount of elapsed time in either a prospective (knowing in advance that they were going to be asked) or retrospective (not knowing that they would be asked) manner. Data Analysis: 3 x 2 x 5 (Music Condition x Paradigm x Time) repeated measures ANOVAs were used to analyze each dependent measure. A univariate analysis of variance was used for time estimation. Results: No significant interaction or main effects for HR, distance, RPE, or time estimation. There was a significant interaction of music condition and time for RPM. Participants’ revolutions per minute (RPM) were affected by music, however that same change was not found in the resulting distance, suggesting the change was not sustained throughout the trial. Conclusion: Music was not found to have a consistent effect on performance in this contrived research environment. Future studies should examine “real world” exercise environments, to determine music’s effect when participants are intrinsically motivated to perform.

Possible reasons for differencesIt is hypothesized that because RPM was a moment-in-time measure (pace measured at that moment), and distance was a cumulative measure, music only had a momentary effect. When RPM measurements were collected (every 3 minutes), participants seem to have pedaled more slowly or quickly (depending on condition), but did not continue this through the remainder of the time block. Participants may not have actively thought about the music and the task itself until the researcher stood by them to take the measurements.

Contrary to previous research (and our hypotheses), performance was not affected by music tempo. The distance pedaled, heart rate (HR), and perception of exertion (RPE) were found to be statistically the same no matter what music tempo was being listened to. Participants’ revolutions per minute (RPM) was found to be affected by music over time, as participants increased their revolutions across the trial in the fast music condition and decreased their revolutions in the slow music condition. This was an encouraging result, until we recognized that distance pedaled had not changed across the same period of time (see Figure 2). If participants were pedaling faster, their distance should have also increased.

Conclusion

Experimental Paradigms: Participants were assigned to one of the following groups, representing the time estimation paradigm in each trial:o Group A: Prospective, Retrospective, Prospectiveo Group B: Retrospective, Prospective, Retrospective

Music Conditions: Participants performed a trial with each of the following music conditions (counterbalanced order). Songs were obscure (to limit recognition) and non-vocal (in order to remove effect of lyrics):o Slow Tempo (~110 bpm)o Fast Tempo (~150 bpm)o No Music (noise cancellation)

Borg RPE Scale: Used to measure participants’ perception of exertion.o Numbers ranging from 6 to 20 (6 = not doing exercise, 20 = maximal exertion)

The current research found that music tempo, while engaged, influences RPM while pedaling on a recumbent bike. This experiment tested participants in a contrived setting where they were to pedal on a stationary bike with no real incentive/motivation other than to assist the researcher and to have a possibility of randomly winning a gift card. This is most likely why participants were not as engaged in the task/music until attention was shown to them (measurements). However, in a “real-world” exercise scenario, the person is exercising for their benefit, therefore potentially more engaged throughout. Future research should examine music’s effect on performance/perceptions in an actual exercise environment.

Task: Pedal at a comfortable pace on recumbent bike for three 15 minute trials, while listening to a series of songs (headphones)
