AKUT STATİK GERME EGZERSİZLERİNİN İZOKİNETİK ARALIKTAKİ PİK TORK VE İZOMETRİK DİZ EKSTANSİYON-FLEKSİYON KUVVETİNE ETKİSİ

Öz: Bu araştırmanın amacı akut statik germe uygulamasının diz ekstansiyon-fleksiyon hareketinde hızın sabit kaldığı izokinetik aralıktaki pik tork ve izometrik pik kuvvete olan etkilerini araştırmaktır. Araştırmaya l4 sağlıklı erkek (20,4:lzl,2 yaş; 70,1:t2,7 kg Vücut ağırlığı; l76,4:t3,6 cm boy uzunlugu) gönüllü olarak katıldı. Gönüllüler ısınmanın ardından izokinetik dinamometrede (Cybex NORM Computerized Sports Medicine Inc. USA) 2100/sn ve 60n/sn hızda izokinetik konsantrik diz ekstansiyon- fleksiyon; ve son olarak da izometrik maksimal ekstansiyon- fleksiyon hareketi yaptılar. Kuvvet ölçümlerinden sonra 3x30 sn süre ile quadriceps ve hamstring kas gruplarına statik germe uygulaması yaptırıldı. Germe uygulamasının ardından kuvvet ölçümleri tekrar edildi. Sonuçlar ortalama standart hata olarak verildi ve germe öncesi- sonrası kuvvet değerleri paired testi ile analiz edildi. Germe egzersizi sonrasında 210°/sn ve 60°/sn hızda izokinetik aralığa ait ekstansiyon ve fleksiyon hareketlerinde pik tork değerlerinde azalma tespit edildi (p

EFFECT OF ACUTE STATIC STRETCH EXERCISES ON ISOKINETIC PEAK TORQUE AT LOAD RANGE AND ISOMETRIC KNEE EXTENSION-FLEXION STRENGTH

Abstract: The purpose of this study was to investigate the effect of acute static stretch on knee isokinetic extension-flexion peak torque at the load range and isometric strength. 14 healthy men (20,4:kl,2 year, 70,1:l:2,7 kg, l76,4:l:3,6 cm) participated in the study voluntarily. After warming up, subjects were tested for isokinetic concentric (210"/ sec, 60“ /sec respectively) and isometric knee extensionflexion by isokinetic dynamometer (Cybex NORM Computerized Sports Medicine Inc. USA). After strength measurements, subjects stretched quadriceps and hamstring muscle groups for 3x30 sec, respectively. In the end, strength measurements were repeated using the same procedure. The results are presented iSEM and the strength values before and after stretch were analysed by paired test. Peak torque values at 210°/sec ve 60"/sec during knee extension-flexion at isokinetic load range decreased after stretch exercise (p
