只有在专项身体训练水平较高的条件下,三级跳远运动员才能取得优异成绩。三级跳远的特点是助跑时的高速度和踏跳时的极大紧张。因此在提高运动技术水平过程中专项身体训练水平的提高具有决定性意义。 1966年德·依利耶夫对三级跳远运动员的专项身体训练水平结构作了因素分析,选出了3个正交因素,它们是速度能力(100米跑成绩),力量能力(抓举、挺 Only in the special level of physical training under the conditions of triple jump athletes can achieve excellent results. Triple jump is characterized by high speed when running and great treading when jumping. Therefore, it is of decisive significance to improve the level of special physical training in the process of improving the level of sports skills. In 1966, De Ilyev made a factor analysis on the level structure of special physical training for triple-jump athletes. Three orthogonal factors were selected. They were speed ability (100-meter run), strength (snatch,
