通常认为机体的年龄越小,身体柔韧性越好,训练效果一般在幼年时期最为显著,儿童少年时期是发展柔韧素质的最佳阶段.然而,在民族健身操的课堂教学中,以“碾、拧、伸、韧”等动作内容教学.结果表明:4项身体素质的纵劈叉、转肩柔韧、俯卧背伸和坐位体前屈的总体平均数∑di都有大幅度的提升,配对t检验表明身体柔韧性虽受年龄的影响,但有针对性的训练能得到有效提高,女生的年龄与身体柔韧素质未呈反比关系.
It is generally believed that the younger the body, the better the body flexibility, the training effect is generally the most significant in infancy, and the best stage for the development of flexible quality in children and adolescents.However, in the national aerobics class teaching, The results showed that the overall average Σdi of 4 physical fitness longitudinal splits, flexible shoulders, prone dorsiflexion and sitting anterior body flexion increased significantly with paired t Test showed that although the flexibility of the body affected by age, but the targeted training can be effectively improved, the girl’s age and physical fitness is not inversely proportional relationship.
