The Relationship between Knee Flexor-Extensor Muscle Strength and Balance Ability in Elite Gymnasts

Objective: The aim of this study was to determine the relationship between balance skill and concentric and eccentric isokinetic knee muscle strength in elite gymnasts. Materials and Methods: A total of 30 (17 males, 13 females) elite gymnasts were included in the study. Y-balance test, isokinetic concentric and eccentric muscle strength measurements were applied to the subjects on different days. Pearson correlation analysis was used to determine the relationship between isokinetic muscle strength and balance ability. The relationship between isokinetic muscle strength and total balance scores of each extremity was evaluated by simple linear regression analysis. Results: Statistically significant, weak and moderate correlations were found between isokinetic muscle strength and balance ability (r=0.36-0.66). As a result of simple linear regression analysis, significant relationships were found between concentric and eccentric isokinetic muscle strength of right and left knees, and total balance score (adjusted R2 =0.16-0.41). Conclusion: Weak and moderate relationships between balance skill and isokinetic knee muscle strength was determined in elite gymnasts. It is concluded that knee joint muscle strength is related to balance ability. However, the level of relationship might vary according to the type of strength and balance exercises.

Jimnastik Sporcularında Diz Fleksör-Ekstansör Kas Kuvvetinin Denge ile İlişkisi

Amaç: Çalışmanın amacı elit jimnastik sporcularında denge becerisi ile diz çevresi konsantrik ve eksantrik izokinetik kas kuvveti arasındaki ilişkiyi belirlemektir. Gereç ve Yöntem: Çalışmaya 30 (17 erkek, 13 kadın) elit jimnastik sporcusu alındı. Katılımcılara farklı günlerde Y Denge Testi, izokinetik konsantrik kas kuvveti ölçümü ve izokinetik eksantrik kas kuvveti ölçümü yapıldı. İzokinetik kas kuvveti ile denge becerisi arasındaki ilişkiyi belirlemek amacıyla Pearson korelasyon analizi kullanıldı. Her bir bacağın izokinetik kas kuvveti ile toplam denge skorları arasındaki ilişki basit doğrusal regresyon analizi ile değerlendirildi. Bulgular: İzokinetik kas kuvveti ve denge becerisi arasında istatistiksel olarak anlamlı zayıf ve orta düzeyde korelasyonlar saptandı (r=0.36-0.66). Basit doğrusal regresyon analizi sonucunda sağ ve sol diz konsantrik ve eksantrik izokinetik kas kuvveti ile toplam denge skoru arasında anlamlı ilişki bulundu (düzeltilmiş R2 =0.16-0.41). Sonuç: Elit jimnastik sporcularında denge becerisi ile diz çevresi izokinetik kas kuvveti arasında zayıf ve orta düzeyde ilişki saptandı. Çalışma sonucunda diz eklemi kas kuvvetinin denge becerisi ile ilişkili olduğu, ancak ilişki düzeyinin kuvvet ve denge egzersizinin türüne göre değişiklik gösterebileceği sonucuna varıldı.
