Comparison of Muscle Strength, Flexibility and Proprioception of Bow and Draw Arms in Archers

Öz

The aim is to examine isometric muscle strength, flexibility and proprioception sense of shoulder joint of bow and drawing arm in archers. Twenty-one archers (9-female, 12-male) in national team included in study. Isometric muscle strength of shoulder abductor-adductor muscles of athletes evaluated with IsoMed2000 device at 90º abduction angle. Flexibility measured using C7-T5 reference points. The proprioception sensation evaluated by digital inclinometer with active reposition test and the measurements performed at 60º-90º-120º target shoulder abduction angle. The data between groups analyzed by using Mann Whitney-U test and within groups by using Wilcoxon Signed Ranks test. Findings of study showed strength of bow arm shoulder abductor muscles was higher than drawing arm, strength of drawing arm shoulder adductor muscles was higher than bow arm, and external rotator muscles flexibility of drawing arm shoulder was higher than bow arm (p<0.05). Shoulder proprioception sense and flexibility of internal rotator muscles of bow arm and drawing arm were similar (p>0.05). Male and female athletes’ bow and drawing arm isometric muscle strength is different in favor of male archers (p<0,05), flexibility of external rotator muscles is different in favor of female archers (p<0,05), flexibility of internal rotator muscles and proprioception sense between gender found to be similar (p>0.05). It is determined isometric muscle strength of bow arm shoulder abductor and drawing arm shoulder adductor muscles in archers was higher than other side. It is determined isometric muscle strength of shoulder abductor and adductor muscles of male athletes was higher compared to female athletes, and flexibility of shoulder external rotator muscles of female athletes was higher than male athletes.

Okçularda Tutuş ve Çekme Kollarının Omuz Eklemi Kas Kuvveti, Esneklik ve Propriosepsiyon Duyusunun Karşılaştırılması

Öz

Bu çalışmanın amacı okçularda çekiş kolu ile tutuş kolunun omuz eklemi izometrik kas kuvveti, esneklik ve propriyosepsiyon duyusunun incelenmesidir. Çalışmamıza milli takım düzeyinde 21 okçu (9 kadın, 12 erkek) katıldı. Sporcuların omuz abdüktör ve addüktör kaslarının izometrik kas kuvveti 90º abdüksiyon açısında IsoMed 2000 cihazı ile değerlendirildi. Esneklik ölçümleri C7-T5 referans noktaları kullanılarak yapıldı. Propriyosepsiyon duyusu dijital inklinometre ile aktif repozisyon testi ile değerlendirildi ve ölçümler 60º-90º-120º hedef omuz abdüksiyon açısında yapıldı. Verilerin analizi gruplar arası ve grup içi olmasına göre Mann Whitney-U testi ve Wilcoxon Signed Ranks test kullanılarak yapıldı. Çalışmamız sonucunda tutuş kolu omuz abdüktör kaslarının kuvvetinin çekiş koluna göre, çekiş kolu omuz addüktör kaslarının kuvvetinin tutuş koluna göre daha fazla olduğu, çekiş kolu omuz eksternal rotatör kaslarının esnekliğinin daha fazla olduğu belirlendi (p<0,05). Çekiş kolu ve tutuş kolunun omuz propriosepsiyon duyusu ve internal rotatör kaslarının esnekliğinin birbirine benzer olduğu belirlendi (p>0,05). Kadın ve erkek sporcuların çekiş kolu ve tutuş kolu izometrik kas kuvvetinin erkekler lehine farklı olduğu (p<0,05), eksternal rotatör kaslarının esnekliğinin kadınlar lehine farklı olduğu (p<0,05), internal rotatör kaslarının esnekliği ve propriosepsiyon duyusunun ise cinsiyetler arasında birbirine benzer olduğu belirlendi (p>0,05). Okçularda tutuş kolu omuz abdüktör ve çekiş kolu omuz addüktör kaslarının izometrik kas kuvveti ile çekiş kolu omuz eksternal rotatör kaslarının esnekliğinin diğer tarafa göre daha fazla olduğu belirlendi. Erkek sporcuların omuz abdüktör ve addüktör kaslarının izometrik kas kuvvetinin kadın sporculara göre, kadın sporcuların omuz eksternal rotatör kaslarının esnekliğinin erkek sporculara göre daha fazla olduğu belirlendi.
