تاثير هشت هفته تمرينات با كش بر حس عمقي مفصل شانه بازيكنان نخبه مرد بسكتبال با ويلچر

The effect of eight weeks of elastic-band exercises on the proprioception of the shoulder in in elite male wheelchair basketball players

زمينه و هدف مفصل شانه ورزشكاران بسكتبال با ويلچر به علت حركات پرتابي بالاي سر، فعاليت هاي تكراري راندن ويلچر و تحمل وزن بدن، متحمل فشارها و آسيب هاي زيادي مي شود كه منجر به كاهش حس عمقي خواهد شد. هدف اين پژوهش بررسي تاثير هشت هفته برنامه تمرينات با كش بر حس عمقي مفصل شانه ورزشكاران نخبه مرد بسكتبال با ويلچر بود. روش بررسي 14 بازيكن (8 نفر گروه تمرين، 6 نفر گروه كنترل) از 2 باشگاه در استان تهران در اين پژوهش شركت كردند. تيم ها به دو گروه مداخله و كنترل تقسيم شدند. در ابتدا با دستگاه آيزوكنتيك بايودكس، حس عمقي عضلات چرخاننده هاي داخلي و خارجي دست برتر بازيكنان، از دو روش حس موقعيت مفصل (JPS) و آستانه تشخيص حركت (TTDM) به وسيله دستگاه آيزوكنتيك بايودكس سيستم 4 اندازه گيري شد، سپس گروه مداخله به مدت هشت هفته برنامه پيشگيري از آسيب شانه با كش را اجرا كردند و در انتها از هر دو گروه مجددا با دستگاه آيزوكنتيك آزمون گرفته شد. يافته ها نتايج پژوهش نشان داد كه اين برنامه تمريني باعث افزايش حس عمقي چرخش دهنده هاي داخلي و خارجي مي شود (05/0

Back ground and aim The shoulder joints of Wheelchair basketball athletes are subjected to a lot of pressure and injuries due to overhead throwing movements, repetitive activities, wheelchair propulsion and body weight-bearing, which can lead to a decrease in proprioception.The aim of this study was to investigate the effect of eight weeks of Thera-band exercise program on the proprioception of the shoulder joint for the elite male in wheelchair basketball athletes. Materials and Methods 14 athletes (8 intervention group, 6 control group) participated in this study from two clubs in Tehran province. The teams were divided into intervention and control groups. Initially, the proprioception of internal and external rotation of dominant shoulder was measured using isokinetic Biodex system 4 by two methods of joint position sense (JPS) and threshold to detect movement (TTDM). Then the intervention group performed a shoulder injury prevention program with a Thera-band for eight weeks, and at the end, both groups were tested again by isokinetic Biodex system 4. Results The results of this study showed that this training program increases the proprioception of internal and external rotation of dominant shoulder (P <0.05). Conclusion The findings of this study suggest that the shoulder injury prevention training program by using Thera-band has been effective on proprioception of internal and external rotations of the wheelchair basketball athletes' shoulders. Therefore, to wheelchair basketball coaches and athletes and athletes of other sports and non-athlete wheelchairs are recommended to perform this exercise program to improve the proprioception of the shoulder muscles.
