The self-myofascial release program in this study was constructed by referring to the National Academy of Sports Medicine policy using a foam roller. The exercise program was applied 3 times a week for 30 minutes for 12 weeks after general training.<br> <strong>Results. </strong>The functions of all variables in the exercise group improved, and the functions of all variables in the control group decreased. As a result of the EX test, dynamic stability was most significantly improved (t=-8.165, p=0.001), and the variable that showed a significant difference according to the interaction effect between groups was dynamic stability (F=10.238, p=0.006)., the joint range (F=4.900, p=0.042).<br> <strong>Conclusion. </strong>It can be seen that the effects on variables between groups differ sharply depending on whether or not self-myofascial release is performed.</div> Professional Futsal Players, Self-Myofascial Release, Performance, Speed, Agility, Quickness, Dynamic Balance, Reaction Time 0 0 http://aassjournal.com/browse.php?a_code=A-11-1538-6&slc_lang=en&sid=1 Hong Yang yanghong7182@naver.com 100319475328460013215 100319475328460013215 No Korea Institute for Applied Anatomy, College of Sports Science, National Sport University of Korea, Yangjaedero 1239, Songpagu, Seoul, Korea Seongoh Kwon humil@naver.com 100319475328460013216 100319475328460013216 Yes Department of Neurosurgery, CHA Gumi Medical Center, CHA University, Pocheon, Korea.
