Abstract des Autors

The aim of this study is to search the relationship between antropometric parameters and muscular strength. During 1994-1996 we consider 563 children, 286 boys and 277 girls, age between 10 and 12 years. The group is evaluated by a jump test (drop jump test of C. Bosco): we pay particular attention to contact time to the floor (TC), to fly time (TV) and to different strategies of jump. Antropometric parameters analysed are height, weight, limb's and trunk's length. The results are analysed and compared with each other by statistic analysis (variance and regression, significance value for p<0.05). No significant difference between male and female, in each age was found. The only improve in TC and the higher value in TV is observed in both sport groups at the age of 12, when limbs are lengthier than trunk. The performance of the group of eleven years old (boys and girls) is worse than the other ones. In conclusion, in accordance to the literature, neuromotory ability of children practising sport is significantly better than that of sedentary groups, even if each subject uses, during jump, a different postural control and strategy of motion.
