影响400米成绩的因素较多,如力量,速度,柔韧,耐力等,但是到了一定水平后,成绩却增长缓慢,有人认为这是出现了速度障碍,也有自身原因,如贫血、缺钙等,如在学生身体健康的状态下,400米成绩女生达到了1分3秒左右,男生达到了53秒左右,如需继续提高就应该从某一两个方面进行突破,成绩就会进一步提高。一、确定好有效距离,进一步提高强度要求对于400米来说,有效距离应该是指在400米以内的距离,如100米、150米、200米、300米等。有人说超过400米以上的距离也应该有效,如500米、
There are many factors affecting the performance of 400 meters, such as strength, speed, flexibility, endurance and so on, but to a certain level, the performance has increased slowly, some people think this is a speed barrier, but also have their own reasons, such as anemia, calcium deficiency, Such as the students in good health state, the results of girls in 400 meters reached 1 minute 3 seconds or so, the boys reached 53 seconds or so, if you want to continue to improve it should be a breakthrough from one or two aspects, the result will be further improved. First, determine the effective distance to further enhance the strength requirements For 400 meters, the effective distance should be within 400 meters, such as 100 meters, 150 meters, 200 meters, 300 meters and so on. Some people say that more than 400 meters above the distance should also be effective, such as 500 meters,
