Winter sports realistic simulations are technologies that make users feel reality and they are used in various fields. In the case of sports simulation, studies are being conducted to synchronize with the actual environment as much as possible. In this study, EMG analysis was performed to make conditions similar to actual environment using EMG in snow. As a result of the analysis, the biathlon did not move only by the flexion and the extension of the knee. There were results with kinematic characteristics. First, because of more load o n the lateral aspect o f the vastus l ateralis o f the lower limb, EMG test r esults were higher. Second, triceps brachii or biceps brachii were higher in upper limb according to the elbow flexion and extension. These results suggest that it is possible to provide a more realistic simulator environment regardless of seasonal and environmental changes of biathlon.
