ÖZET
 Amaç: Bu çalışma erkek sporcularda kuadriseps (Q) açısı ile kuadriseps kasının konsantrik ve eksantrik kas kuvveti arasındaki ilişkinin incelenmesi amacıyla yapıldı. Gereç ve Yöntemler: Çalışmaya, kış sporları (n=28), jimnastik (n=17), atletizm (atlamalar n=20, atmalar n=14, koşmalar n=8), karate (n=22) ve tekvando (n=36) branşından olmak üzere toplam 145 erkek sporcu dâhil edildi. Sporcuların Q açısı değeri, gonyometre ile sırtüstü (pasif) ve ayakta (aktif) ölçüldü. Kuadriseps kas kuvveti, IsoMed 2000® izokinetik dinamometre (Ferstl, Almanya) ile 60º/sn ve 180º/sn hızlarda konsantrik ve eksantrik olarak değerlendirildi. Değişkenler arasındaki ilişkiyi incelemek amacıyla Spearman korelasyon analizi kullanıldı. Anlamlılık düzeyi p<0,05 olarak alındı. Bulgular: Tüm sporcuların Q açısı ile kuadriseps kas kuvveti arasındaki ilişki incelendiğinde, sağ tarafta pasif Q açısı ile 60º/sn ve 180º/sn açısal hızlarda diz ekstansörlerinin eksantrik kuvveti arasında istatistiksel olarak anlamlı negatif yönde çok zayıf ilişki olduğu belirlendi (p<0,05). Branşlar tek tek incelendiğinde ise Q açısı ile kas kuvveti arasında farklı ilişkiler olduğu belirlendi. Sonuç: Q açısı ile kas kuvveti arasındaki ilişkinin genel olarak yorumlanamayacağı, branşa özel yorumlanması gerektiğini düşünmekteyiz. Q açısı, kuadriseps kas kuvveti ile ilişkili olabilir, ancak spor branşına göre bu ilişki değişebilir.

ABSTRACT
 Objective: This study was conducted to investigate the relationship between quadriceps (Q) angle and concentric and eccentric muscle strength of male athletes. Material and Methods: A total of 145 male athletes were included to this study [winter sports (n=28), gymnastics (n=17), athletics (jumping n=20, throwing n=14, running n=8), karate (n=22), and taekwondo (n=36)]. The Q angle of the athletes were measured in supine position (passive) and in standing position (active) with a goniometer. Quadriceps muscle strength was evaluated by IsoMed 2000® isokinetic dynamometer (Ferstl, Germany) concentrically and eccentrically at 60º/sec and 180º/sec angular velocities. In order to examine the relationship between variables Spearman correlation analysis was used. Significance level was taken as p<0.05. Results: When the relationship between Q angle and quadriceps muscle strength of all athletes was examined, it was found that there was a statistically significant negative weak correlation between passive Q angle and eccentric strength of knee extensors at angular velocities of 60º/sec and 180º/sec on right side (p<0.05). When the branches were examined one by one, it was determined that there were different relationships between Q angle and muscle strength. Conclusion: We think that the relationship between the Q angle and muscle strength cannot be interpreted in general and should be interpreted in a specific way to the sport branches. The Q angle may be related to quadriceps muscle strength, but may vary depending on the sport branch.
