크로스컨트리 스키 국가대표와 상비군 선수의 주기별 스프린트 심폐기능지표와 신체구성 변화에 관한 연구

The purpose of this study was to investigate difference of sprint cardiorespiratory index and body composition according to period in national and reserve cross-country skier. A total of 10 cross-country skiers(national 5, reserve 5) were recruited via advice and request cooperation. The measurement variable was heart-rate and body fat(%). The subjects visited to our laboratory three times(spring, summer, and fall season). Body fat was measured every visit to the laboratory and heart rate was measured after sprint exercise. As results, repeated measures analysis of variance showed that recovery heart rate(RHR) have significant difference according to measured time and period. And RHR was significantly low in national group(NP) than reserve group(RG). On the other hand, body fat(%) was significantly high in national group(NP) than reserve group(RG). In conclusion, it was confirmed that the sprint recovery ability of the cross-country skier influenced the performance between the national player and the standing player. In addition, in order to maintain the international level of performance, both the national players and the top athletes should take priority in controlling the body fat percentage.
