Abstract

INTRODUCTION Sprint and vertical jumping abilities are usually improved by jumping exercises [2], and can be classified in general, special and specific. The general exercises are divided into analytical and global, the special in general and oriented, and the specific in pure and analytical [1]. The aim of this work is to evaluate the vertical jumping ability related to special-general exercises and special-soccer oriented exercises.? METHODS 46 amateur soccer players (19.1?4.8 yr; height 176.8?5.8; weight 69.6?7.8) were tested with the Optojump (Microgate, Bolzano, Italy) [3], measuring the vertical jump height in two different jumping exercises. Every jumping session was made up of 3 trials, and the average jump height value has been computed for every one. Special-general exercises squat jumps (SJ) and counter movement jumps (CMJ), both with arms swing, have been performed. In the SJ the subjects started to jump from a standard position (sitting on a bench top 50 cm). The special-oriented exercises have been performed in the same way but with one variation: the ball has been throw by the coach from a distance of about 3 m, giving a task to hit the ball as high as possible (SJball - CMJball). Every trial has been executed after a rest of 30 seconds, while the recovery period between every session was one minute. The data were analyzed using paired T-test using SPSS software v. 17 (SPSS Inc, Chicago, IL). The significant level was set up to p<.05.
