Abstract

Amaç: Literatürde, üniversite basketbol oyuncularında omuz kompleksindeki sporla ilgili adaptasyonlara ilişkin bilgiler sınırlıdır. Bu nedenle bu çalışmada üniversite basketbol oyuncularının baskın ve baskın olmayan omuzlarının rotasyonel kas kuvveti, eklem hareket açıklığı (EHA) akromiyohumeral mesafe (AHD) değerlerinin değerlendirilmesi ve yaralanma risk faktörleri açısından ekstremiteler arası farkların ortaya konması amaçlandı.
Gereç ve Yöntem: Çalışmaya 20 üniversite basketbol oyuncusu (10 erkek, 10 kadın; yaş=20,2±1,8 yıl; vücut kitle indeksi=21,1±2,22 kg/m2) dahil edildi. AHM değerleri, omuz dış (ER) ve iç rotasyon (IR) izometrik ve konsantrik kas kuvvetleri ile omuz ER, IR ve toplam rotasyonel EHA’ları bilateral olarak ölçüldü.
Bulgular: AHM değerleri baskın tarafta omuz 0° (p<0,001) ve 60° abduksiyon pozisyonlarında (p<0,001) daha fazlaydı. Ancak baskın omuzlarda, omuz abduksiyonu 0°'den 60°'ye ilerlendiğinde daha fazla AHM azalması görüldü (p=0,01). Baskın omuzda, izometrik ER kuvvetinin (p=0,006), ER/IR oranının (p=0,001), konsantrik ER kuvvetinin (p<0,001) ve ER/IR oranının (p<0,001) ve ER EHA’nın (p<0,001) daha fazla olduğunu bulduk. Ayrıca AHM değerleri, baskın taraftaki (p=0,012, r=0,552) ve baskın olmayan taraftaki (p=0,041, r=0,461) izometrik ER kuvvetiyle ve baskın taraf (p=0,017, r=0,526) ve baskın olmayan taraf (p=0,013, r=0,545) izometrik ER/IR kuvvet oranıyla da ilişkiliydi.
Sonuç: Üniversite basketbol oyuncuları baskın taraflarında daha güçlü ER kas kuvveti, daha yüksek ER/IR kuvvet oranı, artmış ER EHA ve daha geniş AHM değerleri gösterdi. Ayrıca, daha yüksek ER kas kuvveti ve ER/IR kuvvet oranı daha yüksek AHM ile ilişkiliydi.

Association Between Acromiohumeral Distance, Shoulder Rotational Strength, And Range of Movements in University Basketball Players: A Cross-Sectional Study

Abstract

Objective: Limited information exists regarding the sports-related adaptations at the shoulder complex in university basketball players. Therefore, this study aimed to evaluate the shoulder rotational muscle strength, range of movements (ROM), and acromiohumeral distance (AHD) values to interpret side-to-side differences regarding injury risk factors in throwing and non-throwing shoulders of university basketball players.
Materials and Methods: Twenty university basketball players (10 males, 10 females; age=20.2±1.8 years; body mass index=21.1±2.22 kg/m2) were included. AHD values, isometric and concentric strengths of shoulder external (ER) and internal rotation (IR), and shoulder ER, IR, and total rotational ROM were measured bilaterally.
Results: AHD was greater on the throwing side at 0° (p<0.001) and 60° of shoulder abduction positions (p<0.001). However, throwing shoulders demonstrated more AHD reduction from 0° to 60° of shoulder abduction (p=0.01). We found greater isometric ER strength (p=0.006), ER/IR ratio (p=0.001), concentric ER strength (p<0.001), concentric ER/IR ratio (p<0.001), and ER ROM (p<0.001) in the throwing shoulders. Besides, AHD was correlated with isometric ER strength on the throwing side (p=0.012, r=0.552) and non-throwing side (p=0.041, r=0.461), also, isometric ER/IR strength ratio on the throwing side (p=0.017, r=0.526) and the non-throwing side (p=0.013, r=0.545).
Conclusion: University basketball players demonstrated stronger ER muscle strength, higher ER/IR strength, increased ER ROM, and wider AHD values on the throwing shoulders. Moreover, greater ER muscle strength and ER/IR strength ratio were associated with greater AHD.
