An exercise movement typically involves two phases: a lowering phase and a rising phase. The lowering phase is termed the eccentric phase of the movement and the rising phase is the concentric phase of the movement. During the eccentric phase of the movement, the muscle lengthens while contracting, and during the concentric phase, the muscle shortens while contracting. Much of the research comparing eccentric and concentric contractions has concluded that eccentric training is superior to concentric and traditional training in producing greater hypertrophic, strength, and power adaptations. Music can enhance athletic performance. Some athletes include music as a pre-game ritual in which they get aroused for the competition. Given the research stating that music acts as an ergogenic aid, and other research demonstrating that eccentric exercise produces superior adaptations when compared to concentric exercise, the purpose of this study was to investigate the effects that self-selected music could have on isolated eccentric (SSECC) bench press repetitions to failure when compared to concentric (CON) and eccentric (ECC) bench press repetitions to failure without music. Eleven healthy male collegiate football athletes (age: 20.91 ± 1.58 years; height: 185.42 ± 5.45 cm; weight: 101.95 ± 21.11 kg) were tested. Each participant completed a total of four sessions that were each separated by at least 48 hours to allow for sufficient recovery. The purpose of the first visit was to measure the 1RM for the bench press, and for the participants to become familiarized with the experimental methods. The subsequent three sessions were done in a randomized order. The participants performed a concentric (CON) bench press session with no music, an eccentric (ECC) bench press session with no music, and a self-selected music eccentric bench press (SSECC) session where the participants listened to a playlist composed of songs that they self selected. A repetition of the concentric (CON) condition was defined as a participant beginning the movement with a loaded barbell at the chest (which the spotters lowered) and ending the movement by pushing the barbell as quickly as possible until the elbows were locked out. A failed repetition was defined as the participant being unable to lift the barbell until the elbows were completely extended. A repetition of the eccentric conditions (ECC; SSECC) was defined as the participant beginning the movement by holding a loaded barbell with elbows fully extended and lowering the barbell in a controlled manner for three seconds until the barbell touched the chest.RMANOVA statistics were utilized with a confidence level set at p < 0.05. Effect sizes were also calculated, with a small effect size being d = 0.2, a medium being d = 0.5, and a large being d = 0.8 (Cohen, 1988).The results indicated that the mean number of repetitions for each condition was as follows: CON = 2.36 ± 1.57; ECC = 6.45 ± 3.56; SSECC = 9.00 ± 3.07 (p = 0.001; ES = 0.735; F = 27.80). There was a statistically significant difference between CON and ECC (p = 0.002) and between CON and SSECC (p = 0.001). However, there was no statistically significant difference despite a trend between ECC and SSECC (p = 0.096). Between the CON and ECC conditions, there was a 173% difference in mean repetitions. Between the CON and SSECC conditions, there was a 281% difference in mean repetitions. Between the ECC and SSECC conditions, there was a 39.5% difference in mean repetitions. The results of this study indicate that self-selected music does enhance eccentric bench press performance. Though eccentric repetitions can produce greater forces than concentric repetitions and are also more resistant to fatigue, eccentric exercise while listening to self-selected music can further improve performance than both concentric and eccentric exercise.
