Abstract (2. Language): 
The aim of this study was to investigate relationships between isokinetic paramaters and velocity variables at the different phases of 100m sprint running in the competition phase of sprinters. Thirteen male sprinters from Turkey Track&Field I. and II. Cups voluntarily participated to the study (Age: 22.2±2.7yr, Personnel best 100m result: 10.93±0.21s, Body height: 176.3±2.8cm, Body weight: 74.4±4.7kg, Training age: 4.9±2.8yr). Anthropometric measurements were applied to sprinters. Knee extensionflexion isokinetic muscle strength at different angular velocities (60, 180, and 300°.s- 1) and 100m sprint running including 10m velocity were tested in sprinters. Pearson correlation analysis was utilized for relationships between isokinetic parameters and velocity variables. V40-50m has significant positive relationship with dominant leg knee flexion torque at 600.sn-1 angular velocity (p<.05). V100m, Vmax, and other velocity variables from V0-10m to V50-60m had significant positive relationships with nondominant leg knee extension torque at 1800.sn-1 angular velocity (p<.05). Dominant knee extension torque has significant positive relationships with V0-10, V20-30m and V30-40m. Dominant knee flexion torque has significant positive relationships with V10-20m, V20-30m and V30-40m (p<.05). V100m, V20-30m, and V30-40m velocity variables have positive significant relationships with dominant knee extension and flexion torques at 3000.sn-1 angular velocity (p<.05). In conclusion, relationships between peak torques and velocity variables of 100m sprint running especially in acceleration part were increased and isokinetic peak torque was decreased when angular velocity was increased at the competition phase by elite Turkish sprinters but isokinetic strength criteria and velocity variable correlations didn’t show parallelism for dominant and non dominant leg. It was stated that detailed studies are necessary for relationship between sprint velocity variables and isokinetic strength criteria depending dominant and non dominant leg.

Abstract (Original Language): 
Bu çalışmanın amacı, sprinterlerin müsabaka dönemi izokinetik kriterler ve 100m sprint koşunun çeşitli evrelerindeki hız değişkenleri ilişkilerinin incelenmesidir. Çalışmaya Türkiye Atletizm Birinci ve İkinci Ligi yarışlarında yer alan gönüllü 13 erkek sprinter katılmıştır (Yaş: 22.2±2.7 yıl, En iyi 100m derecesi: 10.93±0.21sn, Boy uzunluğu: 176.3±2.8cm, Vücut ağırlığı: 74.4±4.7kg, Antrenman yaşı: 4.9±2.8yıl). Sprinterlere antropometrik ölçümler, farklı açısal hızlarda (60, 180, 300°sn-1) diz ekstansiyonfleksiyon izokinetik kas kuvveti ve her 10m hızın belirlendiği 100m sprint koşu testleri uygulanmıştır. İzokinetik parametre ve hız değişkenleri ilişkileri Pearson korelasyon analiziyle incelenmiştir. V40-50m ile 600.sn-1 açısal hızda baskın bacak (BB) fleksiyon torku arasında istatistiksel olarak anlamlı pozitif ilişki bulunmuştur (p<.05). V100m, Vmaks, V0-10m’’den V50-60m’ye kadar hız değişkenlerinin tümü 1800.sn-1 açısal hızda baskın olmayan bacak (BOB) diz ekstansiyon torkuyla istatistiksel olarak anlamlı pozitif ilişkiye sahiptir (p<.05). V0-10m, V20-30m ve V30-40m hız değişkenleri BB diz ekstansiyon torkuyla, V10-20m, V20-30m ve V30-40m hız değişkenleri BB diz fleksiyon torkuyla istatistiksel olarak anlamlı pozitif ilişki (p<0.05) sergilemiştir. V100m, V20- 30m, V30-40m hız değişkenleri 3000.sn-1 açısal hızda BB diz ekstansiyon ve fleksiyon torklarıyla istatistiksel olarak anlamlı pozitif ilişki sergilemiştir (p<.05). Sonuç olarak, elit Türk sprinterlerde müsabaka döneminde açısal hız artışına bağlı olarak izokinetik zirve tork azalmış ve bir kısım izokinetik kriterlerle 100m sprint koşusunun özellikle ivmelenme bölümü hız değişkenleri ilişkisi artış sergilemiştir. Fakat her iki bacağın izokinetik kuvvet kriterlerinin hız değişkenleriyle sergilediği ilişki benzerlik göstermediğinden baskın ve baskın olmayan bacağa dayalı izokinetik kuvvet kriterleri ve sprint hız değişkenleri ilişkisine yönelik ayrıntılı çalışmalara ihtiyaç olduğu belirlenmiştir.
