关于少年田径运动员心功指数评价标准的研究

A Study on Estimation Standard of Heart Function Index for Youth Track and Fields Athletes

对1303名少年田径运动员进行了30秒钟30次蹲起机能试验,用所测心功指数进行检验分析表明:无论按生日年龄还是按骨龄年龄分组,同一年龄,同一性别中,男女少年中长跑运动员与男女短跨,投掷运动员的心功指数均值,在绝大多数性别年龄组均存在显著性差异(P<0.05),(P<0.01)。而在年龄、性别之间,以及生日年龄和骨骼年龄之间不存在显著性差异。运用离差法制定了少年田径运动员心功能指数评价表,供机能评定和选材参考。

Youth 1308 track and field athletes were tested while performing a squat-stand test for 30 times within 30 seconds. The results show significant differences (p<0. 05;P<0. 01) of mean heart function index between male and female youth middle and distance runners and hurdlers and throwers in the same age and sex group, no matter whether those groups are divided according to calendar or bone age. However,there is no significant difference between the age and sex,or calendar age and bone age. An estimating table of heart function index for youth track and field athletes was developed to offer reference for functional evaluation and talent identification of athletes.
