核心肌群訓練對於花式滑冰跳躍落地?定性及下肢肌肉活化的影響

PURPOSES: Figure skating has become a popular sport in Taiwan over the last decade. Many young skaters have actively participated in championships on both national and international levels. However, the fundamentals of skating techniques and the sport cultures in Taiwan have not yet reached its optimal potential. Skaters frequently reach the training plateau and waste tons of time in try-and-errors, especially in jumping skills, which plays a critical role in the competitions. The motion of which is the most technical difficult to acquire and is one of the highest scoring elements. A precise core balance control is the key to a successful jump. Based on these observations, this study aims to evaluate the progression of the skaters' on-ice jumping stability during take-off and landing by intervening with a programmed suspension training exercise that is designed to enhance the skaters' core muscle strengths and coordination abilities. The purpose is to understand the effect of core muscle training exercise on the skaters' jumping performance. METHODS: The study recruited figure skaters whose skating skills must meet one of the two following criteria during the time of their participations: 1. The skater had been actively competing in the National Taiwan Figure Skating Championship- ISU Freestyle level 5 or above; 2. The skater had been actively competing in the ISU International Figure Skating Championship. A total of 12 skaters participated (11 females and 1 male) in a 6-week TRX training program. A wireless tri-axial accelerometry and surface electromyography were used to measure the skater's body stability and core muscle activations during on-ice jumping in order to evaluate the skaters' jumping performance. RESULTS: The results showed an increase in skaters' jumping stability and power after the 6-week training. Additionally, after training, the skaters' core muscle strengths and activation timing had significantly improved during jumping. CONCLUSIONS: Intervened with a 6-week TRX suspension training exercise on figure skaters can enhance body control, body coordination, skating performance and reduce the risk of sport injuries. As a result, the training intervention has a positive effect on the overall skating performance.
