大学生板鞋运动员身体形态及体能特征

调查男女大学生板鞋运动员身体形态及体能特征。受试者为大学生板鞋运动员18名(男、女各9名)。身体形态测定项目包括身高、体质量、腰围、臀围、WHR(腰围/臀围)、上臂围、大腿围、体脂肪率以及LBM等指标。体力测定包括最大无氧能力、最大吸氧量(VO2max)、血乳酸(La)、心率(HR)及运动成绩等指标。研究结果发现,大学生板鞋运动员的身体形态各指标的特征、最大血乳酸浓度、VO2max,与同年龄同性别的体育系大学生比较没有明显的差异。但是大学生板鞋运动员的无氧功率,与同年龄同性别的体育系大学生比较有明显的差异。大学生板鞋运动员的VO2max和最大无氧能力都存在性别的差异。以上结果表明,大学生板鞋运动以乳酸供能为主,建议采用最大无氧功率评定板鞋运动员的最大无氧能力,这对板鞋运动员的选材和专项运动能力的评定具有重要的意义。

Characteristics of the body shape and physical strength of college board-shoe players

By measuring the body shape indexes of 9 male and 9 female college board-shoe players,such as body height,body mass,waistline,hip circumference WHR(waistline/hip circumference),upper-arm circumference,thigh circumference,body fat radio and LBM,and their physical strength indexes,such as maximum anaerobic ca-pacity,maximum oxygen intake(VO2max),blood lactic acid,heart rate(HR) and sports performance,the authors investigated the characteristics of the body shape and physical strength of the male and female college board-shoe players,and revealed the following findings: There is no significant difference between various body shape indexes,maximum blood lactic acid and VO2max of the college board-shoe players and those of college students at the same age and with the same gender in the physical education department;however,there is a significant difference be-tween the anaerobic power of the college board-shoe players and that of college students at the same age and with the same gender in the physical education department;there is a sexual difference in both VO2max and maximum anaerobic capacity between the college board-shoe players.The said findings indicate that lactic acid is mainly de-pended on to provide energy for the college board-shoe game.It will be significantly meaningful for the selection of board-shoe players and the evaluation of their specialized athletic capacity to use maximum anaerobic power to evaluate the maximum anaerobic capacity of board-shoe players as suggested by the authors.
