LANGUAGE NOTE | Document text in English; abstract also in Chinese.

A proper and systematic use of physical training can enhance physiological improvement. The present study was aimed to investigate the effects of formal training programs on different physical and physiological profiles of prepubescent tribal boys at different age group. The study was conducted on 69 young boys who were divided into three subgroups i.e. Group-I (n=23, age=9.3±0.19), Group-II (n=18, age=10.1±0.86), Group-III (n=28, age=11±0.22) according to their chronological age. All the boys were inducted in Tripura sports school having formal training of 18 months. Another 64 boys were also chosen as control group (sedentary in nature) from the same community. They were also divided into three subgroups as per their respective test groups. All the boys including sedentary groups belong to similar socio-economic status and dietary habits. Tests were conducted three times in 18 months duration on test groups and twice in control groups to evaluate the height, weight, hand grip strength, body fat%, endurance ability, speed ability, explosive power of the lower extremities and hemoglobin% of all the boys. The result of the present study revealed that almost all the parameters were increased significantly in all three test groups after 18 months duration, except body fat% which was found to be changes insignificantly in group II boys. When the comparison was made among the groups, it was observed that in pre training, all the parameters were changed significantly at p<0.01 & body fat% at p<0.05 level except 800m run and standing broad jump (SBJ) respectively. Significant differences were also observed following 18 months of training in height, hemoglobin percent, 800m run at the level of p< 0.05 and weight, hand grip strength, 30m flying start, aerobic capacity, SBJ at p<0.01 levels, except body fat% which was found to be statistically insignificant. All the parameters were found to be more in Test group-III as compared to other two groups. Prior to training no such significant differences were observed in above parameters with respect to control group. Following 18 months of training, a significant difference was found with respect to control group in all parameters except height, weight (Gr-I & Gr- II) & body fat%. However the increase in above anthropometric and physiological parameters may only because of the augmenting effect of training or due merely because of their growth & development. It has been reported that moderate physical training is necessary for normal growth & development and it is more pronounced in the subject who belongs at the trigger point of adolescence. So it may be concluded that under same nutritional status the effect of formal training is more effective in higher age group as compared to the lower age group.
