背越式跳高过杆技术教学,一 般采用先双脚跳背越式过海绵垫和过杆练习,待背越挺髋、后屈膝、压肩、收腿过杆动作熟练掌握之后,再通过短助跑单腿起跳等背越横杆的练习巩固背越式过杆技术。而单脚起跳背越过杆与双脚起跳背越过杆技术有较大差别,所以学生尽管双脚起跳背越式过杆技术已经掌握了,一进入短助跑单脚起跳过杆总会出现一些技术变形,成为背越式跳高过杆技术教学的一个难点。 单脚起跳背越过杆与双脚起跳背越横杆的判别主要有两点:第一,单脚起跳不像双脚起跳那样背对横杆,而是身体侧对横杆,在空中要转体形成背对横杆姿势,所以在起跳中要注意有助于空中转体的动能形成。第二,
Back to the type of high jump over the pole teaching, the general use of the first double jump over the sponge pad and over the pole exercise, to be back more hip, knee flexion, shoulder pressure, leg movements over the mastery, and then short Run-back single-leg take-off and other cross-bar exercises to consolidate the back-style over-rod technology. However, the single-jump take-off over the pole and the two-leg take-off and back over the pole technique are quite different. Therefore, although the two-legged take-off and back-over technique has been mastered, students always have some technology Deformation, a back-style high jump over a teaching difficult. One-foot take-off jump across the pole and two-leg take-off Behind the crossbar discrimination there are two main points: First, single-foot take-off is not like the feet off the back of the bar, but the body side of the bar, to be turned in the air Body back to the bar to form the posture, so take care to take off in the jump to help form the kinetic energy of the air swivel. second,
