负重训练对河南省中学中长跑运动员成绩的影响

对河南省9所中学的54名800 m跑成绩无显著差异的男生中长跑运动员,采用可调节沙袋衣负重训练,通过正交法设计实验,选取3个因素,各分3种水平:A速度训练(60 m×8、100 m×6、150 m×4)、B负重量(0％、3％、5％)、C耐力训练(1 500m、2 000m、3 000 m),进行8周的实验统计,每周五测...

Effect of Loading Training to Performance of Middle-distance Race Athletes of Henan Middle School

In 9 middle schools of Henan 800 m there are no significant differences in scores of 54 man middle-long-distance athletes.By orthogonal design experiments,The research selects the three factors and three levels: loading weight(0%,3%,5%),velocity training(60 m×8,150 m×6,200 m×5),endurance training(1 500 m,2 000 m,3 000 m).Test statistics are for 8 weeks,measuring 800 m results and data analysis in every Friday.The results show that the impact factors are loading weight,velocity training,endurance training in descent sequence;the best training programs is A2B2C3;the adjustable loading training suits can promote the 800m performance.
