프리스타일스키 우수선수들의 세부종목별 균형능력, 하지 근기능 및 유산소 능력 특성 분석

Abstract

This study aimed to analyze the differences and characteristics of the balance ability, lower extremity muscle function, and aerobic capacity of players in Mogul, Park & Pipe, and Ski Cross among freestyle skiing events, thereby providing basic data for the development of training programs to improve the technical skills of those players in each event. It measured 40 national representative junior skiers, registered in the Korea Ski Association, from the freestyle events of Mogul, Park & Pipe, and Ski Cross.BR Static balance and dynamic balance abilities, and the isokinetic muscular power and muscular endurance of the hip and knee joints were measured for the balance ability and lower extremity muscle function, respectively. In addition, regarding the aerobic capacity, VO₂peak and HRpeak were measured by incremental step-loading tests.BR The results showed that there was a significant difference in the static balance ability of the skiers in each event, (p.01) and the post-hoc analysis results showed that the static balance ability of the Mogul skiers was significantly higher than that of the Park & Pipe and Ski Cross skiers (p.05). It was also found that there was a significant difference in all the items of the lower extremity muscle function of the skiers by event, except the knee joint of 300°/sec (muscular endurance) (p.05). The post-hoc analysis results showed that the lower extremity muscle function of the Mogul skiers was significantly higher than that of the Park & Pipe skiers (p.05) in all items, except the knee joint of 180°/sec Extension and of 300°/sec(muscular endurance) (p.05). In addition, it was found that the Ski Cross skiers had significantly higher 45°/sec Flexion(muscular power) and 300°/sec Flexion(muscular endurance) of hip joints than those of the Park & Pipe skiers (p.05). The comparison of the aerobic capacity showed that there was a significant difference in VO₂peak for each event (p.05).BR In conclusion, the characteristics of physical factors affecting high performance in each of freestyle skiing events were different, and it is considered that subsequent studies need to develop exercise programs for each event and then verify their effects, based on the results of this study.
