It is supposed that, through considering the former results comprehensively, for promoting the flexibility, it is important to make the unfoldness of the extension sides of the disci intervertebrales large, and also it is needed to develop the muscular strength and the elasticity of extensor-muscle. Then, taking these factors into account, the gymnastic training that the author designed was given to the subjects. And the experimental study was tried to test whether such training develops the flexibility or not.
A. Statistical results ;
1. By giving the gymnastic training every day for about more than two weeks, the flexibility (trunk flexion, extension, side-ward bend) are developed.that is;
a. The amount of development of flexibility in the traine1 group was significant statistically but not significant in the control group, at significance level 0.05.
b. The mean of the trained group after training for two weeks was higher than that of the control group. The difference between the two means were significant statistically at significance level 0.05
c. In the trained group after training all the subjects have showed the development of flexibility but only 40% of subjects showed its development in the control group.
B. Electromyographical results ;
a. The electromyographic discharge of post-training has showed more increase remarkably than the EMG of pre-training. Furthermore, it was observed powerful and thick
b. In the EMG of post-training, the joining of new secondary movers and the pause of the antagonist discharge were come out. And then the coordination among the connected muscles for flexibility and the intensification of function of the connected muscles were observed in the EMG after the gymnastic training.
