摘要
为探讨不同年龄中小学生柔韧素质的发展规律,以期为中小学生发展柔韧素质提供理论支撑,对连云港市2010年5 654名小学一年级～高中三年级(对应6～18岁)学生的坐位体前屈数据进行分析。结果表明:6～18岁年龄段男女生随着年龄的增长,柔韧素质总体上呈现增长的趋势。但在柔韧素质的发展过程中,出现"双降双升"现象。第一次"降升"发生在6～15岁,即男生在6～10岁、女生在6～11岁,柔韧素质呈现第一次下降,并分别在10、11岁降到整个年龄段的最低值,之后开始回升,到15岁时达到一个高位,形成了第一个"V"型;第二次"降升"发生在15～18岁,即15岁过后,男女生柔韧素质开始第二次下降,到16岁(男生)、17岁(女生)时降到一个低位(但该值仍高于6岁水平),之后又开始回升,形成了第二个"V"型。认为:6～18岁年龄段学生柔韧素质的第一次下降发生在进入青春期之前,是幼儿骨骼与神经、肌肉发育不相协调的结果;第一次上升发生在开始进入青春期到全面进入青春期期间,是体内激素作用下形成的身体增长全面进入人生第二个发育高峰期的结果;至于柔韧素质保持在高位的第二次降、升的原因,尚有待探讨。
In order to probe into the law of school students＇ flexibility quality development in differ- ent ages, expecting to provide the theory support for the school students＇ developing flxibility quality, the paper makes an analysis of the sit - and - reach data from 5654 students in Lianyungang ranging from grade 1 in primary school to grade 3 in senior high school （corresponding from age 6 to 18 ）in 2010. The result shows that the students＇ flexibility quality generally takes the tendency of going up with the rising of ages from age 6 to 18. But in the process of the development there appears the phenomena of bi - falling and bi - rising. The first falling - rising happens in ages from 6 to 15, namely, the boy from age 6 to 10 and the girl students from age 6 to 11 take the falling of the flexibil- ity quality for the first time, and reaches to the lowest in age 10 and 11 begins to rise again until age 15 to the highest, forming the first V shape. accordingly. After The second falling that, it - risinghappens in ages from 15 to 18, namely, after age 15, the flexibility quality begins to fall for the sec- ond time and reaches to the lowest（ still higher than age 6） in age 16 （boys）and 17 （girls）. After that it begins to rise again, forming the second V shape. The paper finds the first fall from age 6 to 18 happens before entering adolescence. This is the result of lack of harmony between the baby skel- eton and nerves and muscle development. The first rise happens from entering adolescence to all - round adolescence. This is the result of entering the second all - round development peak formed by the body increase in the function of harmone. The reason why the flexibility quality appears the sec- ond fall -rise when buoying up needs to be further researched.
