Introduction: The current study aimed to evaluate the effects of different musical intensities on performance and cardiovascular responses after incremental exercise in male athletes.  Materials and Methods: In this quasi-experimental study with a cross-over design, 15 male athletes were voluntarily selected. The study subjects performed Bruce protocol, along with listening to progressive music, slow music, and without music until exhaustion.  Results: This study indicated that systolic and diastolic blood pressure, maximum oxygen consumption, maximum heart rate, and time to exhaustion insignificantly decreased while listening to slow music, compared to the no music (P=0.134, P=0.993, P=0.999, P=0.160, P=0.819, respectively). Furthermore, while listening to progressive music, compared to no music, the systolic and diastolic blood pressure, as well as maximum heart rate insignificantly increased (P=0.735, P=0.999, P=0.496, respectively); the maximum oxygen consumption and the time of exhaustion significantly increased in the study subjects (P=0.043, P=0.008 respectively). Moreover, while listening to progressive music, compared to slow music, the systolic blood pressure, maximum oxygen consumption, maximum heart rate, and the time of exhaustion significantly increased (P=0.004, P=0.009, P=0.002, P=0.001 respectively); however, diastolic blood pressure presented an insignificant decrease (P=0.253).  Conclusion: The obtained findings revealed that listening to progressive music can affect physiological factors and performance during exercising. It increases the athlete’s motivation and postpones the time to exhaustion to continue exercising; however, listening to slow music creates a state of relaxation during exercise and reduces heart rate. As a result, individuals with hypertension can decline their blood pressure during endurance exercise by listening to soft music.

Football stadiums are the main infrastructures of this popular sport in the society. The purpose of this study is to provide a Pattern for cultural promotion in football fans in stadiums in Iran, which was done by qualitative research method and using grounded theory approach. Through snowball sampling and by conducting 21 semi-structured interviews with university professors and experts in football and culture theoretical saturation was achieved. The results of data analysis in 3 stages of open-coding, axial-coding and selective coding indicate 28 categories that these findings are within the framework of the final model including: Hooliganism, behavioral factors, media, managerial challenges, infrastructural factors and Juridical and legal as causal factors; the nature of football, advocacy and government actions and policy making as context factors; Celebrities, social contexts, economic conditions, Trends and interest, cultural and social and technology as an intervener; manpower, education and training, media, cyberspace, structural strategies and Infrastructural strategies as appropriate ways to promote the level of culture in football fans in stadiums as strategies. According to the proposed pattern, promoting the cultural level of the spectators, marketing development, Exercise promotion, financial development, social progress, the growth of moral security and growth of behavioral security in Iran can be mentioned as positive consequences of promoting cultural levels in football fan in stadiums.
