Concurrent Exercise in Combination With Music Listening in Female Breast Cancer Survivors

"Anaerobic training sessions follow a circuit design alternating upper body, lower body, and core exercises with dumbbells, barbells, and kettlebells. Participants complete 3 sets of 10-15 repetitions per exercise, performed consecutively without rest, at 60-80% of their one-repetition maximum (1RM). Two participants perform the same exercise simultaneously at each station. Load progression is applied by increasing resistance by 10% after successfully completing 3 sets of 12 repetitions across two consecutive sessions.~Sessions begin with a 5-minute warm-up at 50-65% of maximal heart rate (HRmax), followed by nine resistance exercises: kettlebell squats, static plank, bench press, weighted lunges, quadruped superman, seated row, weighted glute bridge, leg raises, and shoulder press. Exercises alternate muscle groups to optimize recovery.~Additionally, participants engage in self-selected aerobic exercise (walking, running, rowing, swimming, or stationary cycling) twice weekly at 65-80"

During the warm-up phase, participants will engage in individual passive music listening, tailored to their personal musical preferences. The music will be delivered via MP3 players or smartphones, where a personalized playlist containing the participant's favorite tracks has been preloaded. Subsequently, during the circuit training session, a group background music playlist will be played through speakers. This heterogeneous playlist is compiled based on the collective musical preferences of all participants. Finally, during the cool-down phase, a common background music selection will be used, featuring a different repertoire from earlier phases. The cool-down will include guided muscle relaxation and breathing exercises assisted by the background music.
