Abstract

This study aimed to examine the relationships between static and dynamic shooting performance and upper-extremity time to peak torque (TPT) and peak torque angle (PTA) in wheelchair basketball players. Fifteen volunteer athletes competing in the Turkish Wheelchair Basketball Super League participated in the study. Isokinetic measurements of elbow flexion/extension and shoulder horizontal abduction/adduction were performed at angular velocities of 60, 180, and 300°/s. Static and dynamic shooting performance was calculated as the ratio of successful shots to total shots during 24-second shooting tests. Pearson correlation analysis was used to analyze the data, and the Benjamini–Hochberg false discovery rate (FDR) correction was applied for multiple comparisons. The findings indicated that static shooting performance was significantly associated with TPT and PTA values of elbow extension on the non-dominant side, TPT during shoulder horizontal abduction on the dominant side, and PTA during elbow flexion on the dominant side. Dynamic shooting performance was particularly associated with TPT variables during elbow extension, elbow flexion, and shoulder horizontal abduction on the dominant side. These results suggest that shooting performance in wheelchair basketball may be related not only to torque magnitude but also to the temporal and angular characteristics of torque production. However, because the study used a correlational design, the findings should not be interpreted causally.

Özet

Bu çalışmanın amacı, tekerlekli sandalye basketbolcularında statik ve dinamik şut performansı ile üst ekstremiteye ait zirve torka ulaşma süresi (TPT) ve zirve torka ulaşma açısı (PTA) arasındaki ilişkileri incelemektir. Araştırmaya Türkiye Tekerlekli Sandalye Basketbol Süper Ligi’nde mücadele eden 15 gönüllü sporcu katıldı. Sporcuların dirsek fleksiyon/ekstansiyon ve omuz horizontal abdüksiyon/addüksiyon hareketlerine ait izokinetik ölçümleri 60, 180 ve 300°/sn açısal hızlarda değerlendirildi. Statik ve dinamik şut performansı, 24 saniyelik testlerde isabetli şut sayısının toplam şut sayısına oranlanmasıyla hesaplandı. Verilerin analizinde Pearson korelasyon analizi kullanıldı ve çoklu karşılaştırmalarda Benjamini–Hochberg FDR düzeltmesi uygulandı. Bulgular, statik şut performansının baskın olmayan taraf dirsek ekstansiyon TPT ve PTA değerleri, baskın taraf horizontal abdüksiyon TPT değeri ve baskın taraf dirsek fleksiyon PTA değeri ile anlamlı ilişkiler gösterdiğini ortaya koydu. Dinamik şut performansı ise özellikle baskın taraf dirsek ekstansiyon, dirsek fleksiyon ve horizontal abdüksiyon hareketlerine ait TPT değişkenleriyle ilişkili bulundu. Bu sonuçlar, tekerlekli sandalye basketbolunda şut performansının yalnızca tork büyüklüğüyle değil, tork üretiminin zamansal ve açısal özellikleriyle de ilişkili olabileceğini göstermektedir. Ancak çalışma ilişkisel tasarıma sahip olduğundan bulgular nedensel biçimde yorumlanmamalıdır.
