Abstract des Autors

Explosive and elastic strength evaluation by means of squat jump and counter-movement jump represent a part of physical fitness in prepubescent age. The aim of the study is jump testing in this age during a follow-up period after school training. The results show a progressive increase in jump capacity with growing (since 9 to 11 years) without a substantial difference between male and female. Prepubescent demonstrates a progressive increment in jump performance after 3 months, above all for male (7.5%) and also for female (1.9%). The results are very similar to other jump testing in prepubescent age, but further studies are necessary for the comparison of different training in the development of explosive strength.
