On the Role of Lyrics in the Music-Exercise Performance RelationshipSanchez, Xavier; Moss, Samantha L.; Twist, Craig; Karageorghis, Costas I.; University of Groningen; University of Chester; Brunel University (Elsevier, 2013-10-27)Objectives. To examine the role of the musical constituent of lyrics with reference to a range of psychological, psychophysical, and physiological variables during submaximal cycling ergometry. Design. Two-factor (Condition x Time) within-subject counterbalanced design. Method. Twenty five participants performed three 6-min cycling trials at a power output corresponding to 75% of their maximum heart rate under conditions of music with lyrics, same music without lyrics, and a no-music control. Cycling cadence, heart rate, and perceived exertion were recorded at 2-min intervals during each trial. Positive and negative affect was assessed before and after each trial. Results. A significant (p = .006) Condition x Time interaction emerged for cadence wherein participants cycled at a higher rate at the end of the task under music with lyrics. Main effects were found for perceived exertion and heart rate, both of which increased from min 2 through to min 6, and for affect: positive affect increased and negative affect decreased from pre- to post-trials. Conclusions. Participants pedalled faster in both music conditions while perceived exertion and heart rate did not differ across conditions. The inclusion of lyrics influenced cycling performance only at min 6 and had no bearing on the remaining dependent variables throughout the duration of the task. The impact of lyrical content in the music-exercise performance relationship warrants further attention in order that we might better understand its role.
