优秀赛艇运动员专项有氧能力对高原训练应答的差异

The Different Response to 8-weeks Altitude Training of Elite Rowers' Aerobic Performance

目的:研究我国优秀赛艇运动员专项有氧能力在8周高原训练后的应答差异及其与促红细胞生成素等的关系。方法:以备战2016年里约奥运会的39名优秀赛艇运动员为研究对象,进行8周高原训练。结果:(1)测功仪6 km成绩总体提高0.10%,应答者平均提高0.67%,不应答者总体下降0.91%;(2)高原训练的第3天,促红细胞生成素和血红蛋白浓度总体分别提高38.41%、4.05%;高原训练的第15天与第3天相比,促红细胞生成素和血红蛋白浓度总体分别下降17.25%、0.58%。结论:(1)赛艇运动员的专项有氧能力变化经过高原训练呈现明显的个体差异;(2)高原训练的应答者与不应答者在高原训练过程中的促红细胞生成素和血红蛋白浓度表现不同的变化规律。(3)2组运动员高原训练第3天促红细胞生成素应激程度和第15天的适应程度存在明显不同,但与专项有氧能力的改善并无明显的线性关系。

Objective:to analyze the different response to 8-week altitude training of elite rowers’aerobic performance and its relations with EPO and Hgb.Methods:The subjects were 39 rowers preparing for Olympic Games in 2016.They took part in altitude training for 8 weeks.Results:①The overall result of 6 km ergometer increased by 0.10%,with the respondent increasing by 0.67%and non-respondent decreasing by 0.91%.②At the 3rd day of the altitude training,there was an increase of 38.41%and 4.05%for EPO and Hgb,respectively,and a decrease of 17.25%and 0.58%at the 15th day,respectively,compared with the 3rd day.Conclusions:①The Chinese elite rowers’aerobic capacity change shows individual differences after the altitude training.②The respondents and non-respondents show different changes of EPO and Hgb during the altitude training.③The rowers’EPO of 3rd and 15th day during the altitude training are different between the two groups,but no linear relation with the change of aerobic performance.
