fa عمومى General كاربردي Applicable <div style="text-align: justify;"><strong>Purpose: </strong>This study aimed to compare the effect of 4 weeks of suspension exercises with TRX and hopping on the static and dynamic balance of male college athletes.<br> <strong>Methods:</strong> This was a quasi-experimental study. In total, 36 male volleyball, basketball, soccer and handball players of the University of Tehran with an age range between 20 and 28 years were selected purposefully and then randomly assigned into 3 groups of control (n=12), TRX suspension exercise (n=12), and hopping exercise (n=12). The exercise groups performed hopping and TRX exercise 3 sessions a week for 4 weeks (12 sessions). Static and dynamic balance of the participants were measured before and after 4 weeks of suspension exercises with TRX and hopping using Biodex balance system. For data analysis paired t test, ANCOVA and Bonferroni test were performed in SPSS. P&le;0.05 was considered as the significant level.<br> <strong>Results:</strong> The scores of the general indicator of the static and dynamic balance test in the 2 exercise groups showed significant improvements, compared to the control group (P&le;0.05). However, there was no significant difference between the effect of hopping and TRX exercise on the static and dynamic balance of the athletes (P>0.05).<br> <strong>Conclusion:</strong> Four weeks of hopping and TRX exercise significantly improves the static and dynamic balance of college athletes; Athletes and coaches can use both of these 2 sets of exercises for improving the static and dynamic balance and for prevention of injury.</div> TRX exercises, Total body resistance exercises, Hopping exercises, Balance 241 250 http://ptj.uswr.ac.ir/browse.php?a_code=A-10-364-1&slc_lang=fa&sid=1 Mehdi Aslani مهدی اصلانی aslani_mehdi92@yahoo.com 0000-0001-7744-2542 No Department of Sport Pathology and Corrective Exercises, Faculty of Physical Education and Sport Sciences, University of Tehran, Tehran, Iran. دانشجوی کارشناسی ارشد آسیب‌شناسی و حرکات اصلاحی، دانشکده تربیت بدنی و علوم ورزشی، دانشگاه تهران، تهران، ایران Homan Minoonejad هومن مینونژاد h.minoonejad@ut.ac.ir 0000-0002-5983-8102 Yes Department of Sport Pathology and Corrective Exercises, Faculty of Physical Education and Sport Sciences, University of Tehran, Tehran, Iran. استادیار گروه آسیب شناسی ورزشی و حرکات اصلاحی، دانشکده تربیت بدنی و علوم ورزشی، دانشگاه تهران، تهران، ایران Reza Rajabi رضا رجبی rrajabi@ut.ac.ir 0000-0002-0464-5688 No Department of Sport Pathology and Corrective Exercises, Faculty of Physical Education and Sport Sciences, University of Tehran, Tehran, Iran. استاد گروه آسیب شناسی ورزشی و حرکات اصلاحی، دانشکده تربیت بدنی و علوم ورزشی، دانشگاه تهران، تهران، ایران
