摘要

在滑冰中,高无氧需求是成功可能性的决定性因素,然而,在年轻的类别中很少研究。本研究旨在分析青春期前女孩轮滑训练的无氧性能。通过随机抽样,对44名在苏克雷-哥伦比亚省练习轮滑的7至10岁女孩进行了评估,这些女孩都在性成熟阶段进行了第1阶段的鞣革。采用适用于儿童人群的RAST测试和myjump2©应用程序测量的Abalakov双足跳(ABK)、右单足跳(RUJ)和左单足跳(LuJ)。在统计分析中,使用SPSS©25.0版本的程序进行方差分析和年龄间跳跃力量和高度的相关性分析。可以观察到,7岁和8岁的女孩比其他组表现出更好的动力生产能力,差异p<。8 ~ 10岁女生的疲劳指数为0.05。相关性p <。ABK、RUJ和LuJ的绝对功率(W/kg)与相对功率(W/kg)之间存在显著性差异。结果表明,跳台产生的机械动力的提高增加了青春期前女孩练习速滑的无氧动力提高的概率。

Anaerobic performance in prepubertal girls practicing racing skating
A high anaerobic demand in skating is a determining factor in the possibilities of success, however, it has been little studied in younger categories. the present study aimed to analyze the anaerobic performance in prepubertal girls who practice roller skating. through a random sampling, 44 girls between 7 and 10 years old, who practice roller speed skating in the Department of Sucre-Colombia, all with tanner stage 1 for sexual maturation, were evaluated. The RAST test adapted to pediatric population and the Abalakov bipodal jumps (ABK) and right unipodal jumps (RUJ) and left unipodal jumps (LuJ) measured by the myjump2 © application were applied. In the statistical analysis, the SPSS © version 25.0 program was used to perform the analysis of variance and the correlation between the power and height of jumps between ages. It can be observed that girls of 7 and 8 years old, present better power production in comparison with the other groups, differences p<.05 were found in the fatigue index between girls of 8 and 10 years old. Correlations p<.05 were found between absolute power (W) and relative power (W/kg) with ABK, RUJ and with LuJ. It is concluded that the improvement of the mechanical power produced in jumps increases the probabilities of improvement of the anaerobic power in the group of prepubertal girls evaluated who practice racing skating.
