It was aimed to compare the knee joint isokinetic strength ratios of elite athletes in different snow branches and evaluate the relationship between them. In the scope of snow branches (alpine skiing, ski running, snowboarding, ski jumping and biathlon), the mean age is 18.3±2.2 years, theme an height is 171.47±4.91 cm, and theme an body weight is 65.65±10,85 kg 40 male athletes were included. The athletes' knee flexion/extension muscle strengths were measured as 5 repetitions at an angular speed of 60°/sec and 15 repetitions at an angular velocity of 180°/sec. One way anova analysis was used to determine the differences between the groups knee joint flexor/extensor muscle strengths. Poct hoc Tukey analysis was applied to determine the difference between branches. There is significant difference in the dominant, non-dominant extensor muscles of the branches at 60-180°/sec angular velocity (p0.05). The strength of the knee joint extensor muscles of ski jumping athletes is lower compared to other branches; A force imbalance was detected in the H/Q ratios of alpine skiing and cross-country skiing athletes at an angular speed of 60°/sec, against the detriment of alpine skiing. When it is necessary to determine strength imbalance in athletes, it is recommended to perform corrective exercises to eliminate H/Q disproportion.
