Effect of 18 Days Sub-altitude Training on Physiological Function and Sports Performance of Figure Skaters
【Abstract】Objective: To figure out the effect of 18 days altitude training on physiological function and sports performance of figure skaters. Methods: Ten figure skaters of the national youth team completed 18-day sub-altitude training in Xinjiang Ice Sports Center at the altitude of 1 650 m. During the sub-altitude training, skaters’ morning heart rate (HR) and SpO2 were tested every day; their exercise ability was measured before, during and after 18 days sub-altitude training, the indexes include blood biochemical indexes, aerobic capacity (YOYO test) and specific abilities (specific test). Statistical analysis was performed by repeated measures ANOVA and paired T test. Results: 1) During the sub-altitude training period, the morning HR of figure skaters reached the highest on the 2nd and 3rd days, and then it decreased. The level of SpO2 gradually increased, and kept above 97% after the 9 th day. 2) During the sub-altitude training period, athletes’ HTC increased significantly, but other blood indicators did not change. 3) After the sub-altitude training, athletes’ aerobic ability was improved, they finished more steps and longer distance in YOYO test. The average HR, the HR immediately after exercise and the lactic acid level immediately after exercise remained unchanged when the difficulty of special ice test increased. Conclusions: 1) During 18 days sub-altitude training period, skaters’ morning HR gradually decreased, SpO2 increased, which indicated that the figure skaters were adapted to the sub-altitude training environment. 2) After 18 days sub-altitude training, the aerobic ability of figure skaters has been improved to a certain extent, and the specific ability has a tendency to improve.
