A influência da música em alto volume no desempenho de força e na percepção subjetiva de esforço

Abstract

Different studies suggest that listening to music during physical activity can distract from the discomfort associated with physical effort and fatigue, improving performance and contributing to a reduction in the rating of perceived exertion (RPE). In this context, the purpose of the study was to investigate the influence of loud music on resistance training performance and RPE during resistance exercises. Additionally, the study aimed to analyze whether the inclusion or removal of music throughout the protocol can alter performance and RPE when compared to protocols in which music was absent or present throughout the entire experimental session. Eighteen trained male individuals participated in the study (23.83 ± 4.69 years; 78.06 ± 8.63 kg; 177.16 ± 7.22 cm), undergoing six experimental sessions. In session 1, familiarization with the 1-repetition maximum (1RM) test and anchoring of RPE in the barbell bench press exercise was performed; in session 2, the 1RM test and RPE anchoring were conducted. In sessions 3, 4, 5, and 6, the volunteers performed the four experimental conditions, randomly allocated. In Sessions 3, 4, 5, and 6, participants completed the four experimental conditions randomized as follows: music throughout the protocol (WM); no music throughout the protocol (NM); the first three sets without music and the last three sets with music (NM/WM); and the first three sets with music and the last three sets without music (WM/NM). In all sessions, 6 sets were performed until muscle failure, with 50% of 1RM and a 3-minute rest between each set. The data were expressed as mean ± standard deviation, and the variables analyzed in the four sessions were the number of repetitions and RPE.The results for the total number of repetitions showed that only the WM x NM condition (85,78 ± 15,47 x 80,67 ± 15,21) presented a statistically significant difference (p=0,028). For the average number of repetitions, ANOVA showed no interaction in any of the comparisons (WM x NM; WM x WM/NM; NM x NM/WM). However, ANOVA showed a main effect of condition for the WM x NM analysis (14,29 ± 5,47 x 13,44 ± 5,38; p= 0.028). For the RPE, ANOVA showed no interaction between conditions and sets; however, a main effect of sets was found (p=0.0003), regardless of the condition, indicating an increase in RPE over time. In this sense, the present study concluded that loud music is not capable of altering RPE in any of the conditions. Additionally, for strength endurance performance data, when analyzing the WM x NM session, the results show a statistically significant difference for the WM session, differences that are not found in the sessions where music is added or removed throughout the protocol.
