The purpose of this study was to examine the effect of sport enjoyment on leisure identity and ski participation. To collect data, the purposive sampling method was used. The collected 256 samples of advanced level skiers were analyzed using SPSS 12.0 program. Through statistical analysis, following results were extracted. First, some factors of sport enjoyment had differences in the mean score based on some demographical characteristics. However, leisure identity had no difference. The degree of ski participation had some differences in the mean score based on some demographical characteristics. Second, some factors of sport enjoyment influenced leisure identity. Third, some factors of sport enjoyment influenced the degree of ski participation. The results of this study are expected to be used for understanding advanced level skiers and satisfying the needs of advanced level skiers.

Objective: The purpose of this study was to confirm that the cross-country ski sprint course in PyeongChang, where the 2018 Winter Olympics course was to utilize wearable devices equipped with inertial measurement unit (IMU), global positioning system (GPS) and heart rates sensor. Method: For the data collection, two national level cross-country (XC) skiers performed classic technique on the entire sprint course. We analyzed cycle characteristics, range of motion on double poling (DP) technique, average velocity, and displacement of 3 points according to the terrain. Results: The absolute cycle time gradually decreased during starting, middle and finish sections. While the length of the DP increased and the heart rates tended to increase for men skier. In addition, the results indicated that range of motion of knee joint during starting and finish section decreased more than middle section. The errors of latitude and longitude data collected through GPS were within 3 m from 3 points. Conclusion: Through the first case study in Korea, which analyzed the location and condition of XC skiers in the entire sprint course in real time, confirmed that feedback was available in the field using various wearable sensors.
