Physiologic and Perceptual Responses During Resistance Exercise With Self-Selected and Nonpreferred Music.

Self-selected music resulted in greater repetitions for squat and deadlift exercises compared to nonpreferred music.

• A significant trial × exercise interaction was found (p = 0.016)
• Greater repetitions were performed for squat during SSM than NON (p = 0.005)
• Greater repetitions were performed for deadlift during SSM than NON (p = 0.011)
• No significant difference in repetitions was observed for bench press or bent-over rows
• Subjects completed 3 sets to failure of each exercise

Motivation and enjoyment decreased significantly during nonpreferred music but remained stable during self-selected music.

• Significant trial × time interactions were found for both motivation (p < 0.001) and enjoyment (p < 0.001)
• No significant changes from pre- to postexercise were observed for motivation and enjoyment during SSM
• Significant decreases in motivation and enjoyment occurred during NON from pre- to postexercise
• Assessments were taken before the warm-up, after each exercise, and after the session

Self-selected music was associated with higher focus and energy levels compared to nonpreferred music.

• Main effects favoring SSM were found for focus (p = 0.023) and energy (p = 0.020)
• These perceptual measures were assessed before the warm-up, after each exercise, and after the session
• No significant effects of sex were observed for these variables

Self-selected music did not increase physiological strain or perceived exertion compared to nonpreferred music.

• No significant effects were noted for heart rate, muscle oxygen saturation, muscle activation, or ventilation
• Rating of perceived exertion was recorded after each set and showed no significant differences between conditions
• No fatigue differences were observed between SSM and NON conditions
• The additional repetitions performed during SSM were achieved without increases in exertion or fatigue

No sex differences were observed in any measured variable across the entire study.

• The study included 9 men and 10 women who were all resistance-trained
• No effects of sex were observed for any physiological, perceptual, or performance variable
• Data were analyzed using 3-way analysis of variance with post hoc Bonferroni-adjusted comparisons

The study used a counterbalanced crossover design with resistance-trained participants performing multi-exercise sessions under two music conditions.

• Nineteen resistance-trained subjects (9 men, 10 women) participated
• On visit 1, body composition was assessed and 1 repetition maximum was estimated for squat, bench press, deadlift, and bent-over rows
• Subjects created a 5-song self-selected music playlist and identified their least preferred genre for a nonpreferred playlist
• On 2 subsequent visits, subjects completed 3 sets to failure of each exercise while listening to SSM or NON in counterbalanced order
• Blood lactate, focus, energy, fatigue, motivation, and enjoyment were assessed before warm-up, after each exercise, and after the session
