The aim of this study was to investigate the effect of different music rhythms on cardio respiratory responses during incremental exercises in young men. For this purpose, 17 non-athlete healthy males (ages: 19.76±0.97 yr, height: 176±6.72 cm, weight: 68.5±5.95 kg) voluntarily participated in this study. They performed Bruce protocol until exhaustion with no music, slow music and fast music conditions through counter balance format. All cardio respiratory indexes were measured in the 3rd, 6th and 9th time intervals. Each time interval was 72 hours. The results showed that listening to music (fast and slow) during incremental exercise significantly decreased perceived exertion (P=0.001) and respiratory rate per minute (P=0.0001) in the third stage, heart output, VO2, heart rate, ventilation per minute in all stages of test (P?0.05). But there was no significant change in Vo2max (P=0.764), maximum heart rate (P=0.478), stroke volume and tidal volume in all stages of the test (P<0.05). It can be concluded that music may influence perceived exertion in moderate intensity exercises. Probably, maximum levels of some cardiovascular variables are less influenced by music.
