Background: There is a limited amount of research investigating the psychological effects of music on anaerobic performance, in particular isometric contraction exercises. Aims: The aim of the present study was to investigate the psychological effect of self-selected music on performance, affect and mood state during a front elbow plank. Method: Undergraduate sport students studying at the University of Chichester (n = 22; 9 Male, 13 Female) were required to hold the front elbow plank until voluntary physical exhaustion was reached under three experimental conditions (music, white noise and no-music) as part of a repeated measures design. Testing order was randomised to control for the learning effect. Plank performance time (PPT) was measured using the total PPT reached before voluntary physical exhaustion was met. Affective state was measured using The Feeling Scale (valence) and The Felt Arousal Scale (arousal) at four time points. (T1) immediately pre, (T2) mid-point, (T3) immediately post, and (T4) 10-minutes post exercise. Mood was measured using the POMS-sf, immediately pre (T1) and 10-minutes post (T2) exercise. Results: A one-way repeated-measures analysis of variance (ANOVA) revealed that PPT was significantly longer in the music condition compared to the control condition (p = .023). A series of two-way repeated-measures ANOVA’s revealed that condition had a non-significant effect on Valence and Arousal. Time Point had a significant effect on Valence (p < .001) and Arousal (p < .001). But no significant condition*time point interaction was found for Valence or Arousal (p < .05). Total Mood Disturbance (TMD) was not significantly affected by Condition or Time Point (p < .05), but an overall condition*time point interaction was found (p = .022). Conclusion: Listening to music significantly increases plank performance time and reduces total mood disturbance compared to white noise or no-music. Yet listening to music does not significantly affect valence or arousal.
