为探讨我国优秀单板U型场地滑雪运动员身体成分特征,采用文献资料、实验检测和数理统计等方法对我国单板U型场地滑雪运动员的身体成分进行调查,并按照性别以及运动员级别的不同进行统计分析。结果表明:我国单板U型场地滑雪运动员肌肉、骨骼发育水平良好、肌肉增厚以及骨骼和关节较大,身材不太细长身高每单位重量大,四肢重量相对大身体形态偏向瘦小;运动员身体较为强壮、体质好,骨骼肌的收缩有力、运动员有氧耐力和运动能力较高、运动员身体皮下脂肪含量较大;其身体成分变化以身高体重的不断增加、瘦体重小幅递减后的快速增高、脂肪重量和体脂百分比快速递增后的平缓下降为主要特征。同时依据研究中发现的不足之处提出加强体能训练;调整饮食结构;完善训练计划等建议,为促进我国单板U型场地滑雪运动的发展提供参考。
In order to explore the characteristics of body composition of excellent snowboard athletes in China, the author used the methods of literature, experiment and mathematical statistics to investigate the body composition of snowboard athletes in China. The differences were classified according to sex and athlete level Statistical Analysis. The results showed that the veneer U-shaped skier in our country had good muscular and skeletal development, thickening of the muscle, larger bones and joints, less slender body height and weight per unit weight, Strong body constitution, strong contraction of skeletal muscle, athletes aerobic endurance and high exercise capacity, athletes body subcutaneous fat content larger; changes in body composition with increasing height and weight, lean mass slightly decreased after the rapid increase, The main feature is the gentle decline after fat weight and body fat percent increase rapidly. At the same time, based on the deficiencies found in the study, it is suggested that strengthening physical fitness training, adjusting diet structure, improving training plan and so on, which will provide reference for promoting the development of snowboarding in veneer U-shaped field in our country.
