Music in the eye of the beholder: a pupillometric study on preferred background music, attentional state, and arousal

Impact of Augmented Feedback and Music During the Bench Press Resistance Exercise: Does Their Combination Compromise Mechanical Performance?

BACKGROUND

Verbal feedback (knowledge of results [KR]) and listening to music are common ergogenic strategies used to boost athlete performance during resistance exercise. No previous research has explored their effects when both strategies are combined in the same exercise session (KR+music). This study aimed to examine the impact of providing KR, listening to music, and their combined effects on: (1) mechanical responses (number of repetitions, fastest velocity, and average velocity in a set), and (2) perceptual responses (feeling scale [FS], rating of perceived exertion [RPE], and rate of perceived discomfort [RPD]) when a determined percentage of velocity loss (%VL) is prescribed.

HYPOTHESIS

Providing KR or listening to music would provide an ergogenic effect on these outcomes whereas KR+music can compromise mechanical performance.

STUDY DESIGN

Cross-sectional study.

LEVEL OF EVIDENCE

Level 3.

METHODS

Fifteen recreational resistance-trained men were tested on 5 occasions separated by a 48 to 72 hour washout period. The first session was used to determine the bench press 1-repetition maximum (1RM) strength. The 4 experimental sessions were identical (4 sets at 70% 1RM with a 20%VL during bench press exercise) except for the intervention (ie, control, KR, music, and KR+music) used randomly on each session.

RESULTS

The findings revealed that: (1) mechanical performance was significantly greater for the music condition (from 5.7% to 20.4%), followed by the KR+music (from 4.9% to 15.4%) and KR (from -0.4% to 8.1%) condition, and (2) greater FS values were found for music compared with control condition, while no significant differences were reported for RPE or RPD.

CONCLUSION

Listening to music enhances bench press performance and mood; adding KR does not compromise these benefits.

CLINICAL RELEVANCE

Recreational athlete performance may benefit from listening to music, and KR+music does not compromise this effect. However, athlete preference should take priority when implementing these ergogenic strategies.

The role of mood and arousal in the effect of background music on attentional state and performance during a sustained attention task

Across two online experiments, this study explored the effect of preferred background music on attentional state and performance, as well as on mood and arousal, during a vigilance task. It extended recent laboratory findings-showing an increase in task-focus and decrease in mind-wandering states with music-to environments with more distractions around participants. Participants-people who normally listen to background music during attention-demanding tasks-completed the vigilance task in their homes both with and without their chosen music and reported their attentional state, subjective arousal, and mood valence throughout the task. Experiment 1 compared music to relative silence and Experiment 2 compared music against the backdrop of continuous noise to continuous noise alone. In both experiments, music decreased mind-wandering and increased task-focus. Unlike in previous laboratory studies, in both experiments music also led to faster reaction times while increasing low-arousal external-distraction states. Importantly, mood and arousal increased with music and were shown to mediate its effects on reaction time and for the first time attentional state, both separately and together. Serial mediation effects were mostly confined to models where mood was entered first and arousal second and were consistent with the mood-arousal account of the impact of background music listening.
