Preferred Music Genre Benefits During Strength Tests: Increased Maximal Strength and Strength-Endurance and Reduced Perceived Exertion.

Abstract

The ability to increase muscle strength seems to be influenced by extrinsic factors such as the characteristics of an exercise environment. Given that many people train while listening to music, the music environment is an important research topic. However, no studies have investigated whether a preferred music genre differentially affects strength production when compared to a non-preferred music genre. This study evaluated the influence of listening to varied conditions of musical genre preference on maximal strength and strength-endurance testing, and on ratings of perceived exertion (RPE). We submitted 20 young men to three different listening conditions during strength testing: (a) preferred music genre (PMG), (b) non-preferred music genre (NPMG), and (c) no music (NM), with the order of these conditions randomized. We measured maximal strength with a handgrip dynamometer, strength-endurance through the participant's maximal repetition execution in the lat-pulldown exercise, and RPE by participant-completed Borg's scales at the end of the strength tests. Using three-way analyses of variances (ANOVAs) and a significance level of p < 0.05, we found that participants produced higher maximal strength, performed more repetitions of the lat-pulldown exercise, and reported decreased RPE in the PMG condition, compared to the NPMG (maximal strength p < 0.01, strength-endurance p < 0.01, RPE p = 0.016) and NM (maximal strength p < 0.01, strength-endurance p < 0.01, RPE p = 0.023) conditions. Individually determined PMG appears to improve maximal strength and strength-endurance performance during exercise, and to decrease RPE in the PMG condition.
