关于确定什么样的运动生理状态将有助于提高长跑运动成绩的文章,以前多是针对1500米以上距离而言的,而对800米跑则很少有人关注。因此,以下的研究文章将就800米跑中已经确定的运动生理特征与体表成分之间的相互关系作一番调查,包括体表成分,最大吸氧量,(VO_(2max)),省力跑等。请11名男子短跑运动员进行数次100米和300米的冲刺性表演赛跑,并将所得到的数据进行逐步分段的多重回归分析。我们用800米跑所用时间作为一个可变参数,用上面提到的100米和300米跑的次数,体脂率,省力跑和最大吸氧量等数据作为独立的变量,占总参数的比例很大(r~2=0.89)。当把最大吸氧量,体脂率,省力跑等参数填进一个数表模型进行比较分析时(该数表模型包含有100米和300米跑所用时间的参数,其参数是总参数的85％,(?)~2=0.85),所得出的参数并没有什么新的意义。这些数据再一次证明了这一观点:在800米跑中,肌肉里的三磷酸腺苷(ATP)很大一部分是通过无氧代谢途径即糖酵解途径产生并对机体起作用的。
Articles on determining what kind of exercise physiology will help improve long-distance athletic performance are mostly for distances above 1,500 meters, while few are for 800-meter runs. Therefore, the following research article will investigate the relationship between the physical characteristics and the body surface composition determined in the 800-meter run, including body composition, maximum oxygen uptake (VO_ (2max)), labor saving Run and so on. Eleven male sprinters were asked to run several sprint races of 100 meters and 300 meters, and the data obtained were subjected to stepwise and multiple regression analysis. We use 800 m running time as a variable parameter, with the above-mentioned 100 and 300 meters running frequency, body fat rate, labor-saving and maximum oxygen uptake and other data as independent variables, the ratio of the total parameters Large (r ~ 2 = 0.89). When the maximum oxygen uptake, body fat rate, labor-saving running and other parameters into a table model for comparative analysis (the table model contains 100 meters and 300 meters run time parameters, the parameters of the total parameters of 85 %, (?) ~ 2 = 0.85), the resulting parameters have no new meaning. These data once again prove the point: In the 800-meter run, a large part of the ATP in the muscle is produced by the anaerobic metabolic pathway, the glycolysis pathway, and acts on the body.
