This study examined the effects of lyrical music compared to non-lyrical music on 5 km running performance. Thirteen subjects with an average age of 33.5 ± 8.3 years of age ran three separate 5 km time trials. The first trial acted as a familiarization trial where no music was present, followed by either a lyrical or non-lyrical music trial in a random counterbalanced order. Trial times, RPE, HR, and questionnaire information was analyzed using paired samples t-tests, ANOVA, and multivariate regression analyses. Lyrical music showed a significant improvement over non-lyrical music improving performance time compared to non-lyrical music, on average by 36 ± 41s (p=.000). While not statistically significant, a trend showing lyrical music was faster than no music, followed by the slowest trial of non-lyrical music. No change was detected in HR, or RPE at the 3.05 km mark suggesting that at the end although subjects were working harder (indicated by the faster completion times) they do not perceive themselves to be working harder. A correlation between increased mileage and the decreased effects of music as an ergogenic aid was seen (p=.044 r=.638) which supports previous research. This study suggests that lyrical music may improve 5 km running performance compared to no lyrical music.
