【摘要】：目的:对现有国民体质监测(幼儿部分)中使用的反映灵敏协调能力的指标——双脚连续跳进行改良。方法:对1 261名3~6岁幼儿进行现有灵敏协调能力评价方法(50 cm间距设置双脚连续跳)的测试与分析;提出改良间距设置的双脚连续跳测试方法,将相邻软方包之间的间距设置为60 cm和70 cm,在219名4.5~6.5岁幼儿中对原方法和改良后的方法进行测试与效果分析;在61名4.5~6.5岁幼儿中获取其完成不同间距设置双脚连续跳的运动学参数,以验证改良方法的效度。结果:现行双脚连续跳测试的成绩虽随着年龄的增长而增长,但此方法无法很好的区分年龄相近的幼儿能力上的差异;且无法对同一年龄却具有不同灵敏协调能力发育水平的幼儿进行很好的区分。对不同间距设置的双脚连续跳进行运动学参数分析,结果显示:1)60 cm间距双脚连续跳的着地时间最短,50 cm间距双脚连续跳着地时间最长。2)50 cm、60cm和70 cm间距双脚连续跳的跳跃距离与间距设置的差值分别为1.4cm、1.1 cm和0.1 cm,跳跃距离的变异系数分别为0.12、0.10和0.12。3)60 cm间距双脚连续跳的着地角和离地角最小,70 cm间距次之,50 cm间距最大。结论:改良的双脚连续跳测试方法在4.5~6.5岁幼儿中具有较好的普适性,4.5~6.5岁幼儿宜选用60 cm间距双脚连续跳进行测试。
[Abstract]:Objective: to improve the sensitivity and coordination of the existing national physique monitoring (children's part) - a double foot continuous jump for improvement. Methods: 1261 3~6 years old children were tested and analyzed for the current sensitive coordination evaluation method (50 cm spacing setting double foot jump), and a double foot continuous jump test with improved spacing was proposed. Test method, the distance between adjacent soft packets is set to 60 cm and 70 cm, the original method and the improved method are tested and analyzed in 219 4.5~6.5 years old children. In 61 4.5~6.5 years old children, their kinematic parameters are obtained to complete the double foot jump at different distances, so as to verify the validity of the improved method. Results: the current double feet. The results of continuous jump test increase with age, but this method can not distinguish the differences of young children with similar age, and can not make a good distinction between children with different agility and coordination ability at the same age. The results are as follows: 1) the ground time of the 60 cm spaced double foot continuous jump is the shortest, the 50 cm distance between the feet is the longest time of.2) 50 cm, the difference between the jump distance and the distance between the 60cm and the 70 cm distance between the feet is 1.4cm, 1.1 cm and 0.1 cm respectively, the variation coefficients of the jumping distance are 0.12,0.10 and 0.12.3) and the 60 cm spacing is continuous. The jumping angle and the ground angle are the smallest, the 70 cm distance is the second and the 50 cm distance is the largest. Conclusion: the improved double foot continuous jumping test method has a good universality in the young children of 4.5~6.5 years old, and the children of 4.5~6.5 years old should choose the double foot jump of 60 cm spacing to carry on the test.
