短跑中高水平运动员的最高步频每秒可达4.5-5.5步,全程保持这样的节奏只有在经过相当的训练后才有可能。我们对使用“牵引”器时在运动员大腿上固定环圈(500克)和弹性拉杆的方法增加负荷的条件下各种练习对短跑运动学的影响进行了研究,这些研究能弄清与短跑运动员的训练条件相同的情况。参加实验的是7名健将级和预备健将级短跑运动员。实验中研究了在自然条件下和在借助训练器人为地减轻运动员体重10-15%以及以运动员体重的5%、10%和15%的力量作前
Sprinter high-level athletes in the highest pace of up to 4.5-5.5 steps per second, the entire process to maintain such a rhythm only after considerable training is possible. We studied the effects of various exercises on sprint kinematics with increased load on the rings (500 grams) and elastic tie rods on the athlete’s thigh when using a “tractor”, and these studies shed light on the importance of working with sprinters The same training conditions. To participate in the experiment is 7 athlete-level and prepare healthy sprint class athlete. Experiments were conducted to study the effect of artificially reducing the weight of athletes by 10-15% and by 5%, 10% and 15% of the weight of athletes under natural conditions and with a trainer
