The aim of the study is to examine the relationship between the concentric and eccentric strengths of the knee flexor and extensor muscles and competition performance in elite short track speed skating athletes. Nine elite male speed skating athletes between the ages of 18-22 were included in the study. In order to determine the competition performances of the athletes, 500 m, 1000 m and 1500 m times were taken. Height and body weight measurements were taken from the athletes on the first day of laboratory tests. ISOMED 2000 isokinetic strength device was used to determine the concentric and eccentric muscle strength of the athletes. Isokinetic strength measurements were performed in concentric/concentric and eccentric/eccentric modes for 8 repetitions at a speed of 60o/sec. Measurements were made in the flexion/extension movement of the knee joint. Isokinetic measurements were taken on two separate days, and distance measurements were taken on three separate days. SPSS v25 statistical program was used to analyze the data obtained. Pearson Correlation analysis was performed to reveal the relationship between variables. In statistical analysis, the significance level was determined as 0.05. As a result of the research, it was determined that there is a statistically moderately significant relationship between the concentric and eccentric strength of the knee flexor and extensor muscles and the 500 m distance performance. However, no significant relationship was found with 1000 m and 1500 m distance performances.
