PROBLEM. The characteristics demands of the load of the common sport games are different, but many similarities are obvious. 'They all require a high ability of anticipation. reaction- and action speed. Many actions like dribbling, feint. tracing and attacking adversary are carried out with highest intensity (speed) in combination with rapid changes in direction of motion In split seconds decisions between alternative movements must be reached and go into action. The available speed tests were not able to satis6 these requirements (e.g. 1, 2). The aim of this study was to evaluate tests for speed-diagnostics. which consider the specific demands of the sport games soccer, handball, tennis. MEI'HODS The length of the run and the kind of changes of direction depends on the conditions of the sport game For the time recording we used a measuring system of 4 double lightbars Each run starts from a defined position on a contact platform. The starts were free selected and/or given by an optical signal. The following abilities here recorded differently in separate tests: 4 the ability to start and accelerate straight on. I3 the ability to start. decelerate. accelerate in connection with changes in direction of motion the ability to react in connection \kith selection and following game specific movement. calculated by test-retest correlation coefficient To check the selectivity of the tests analysis of variance were used to calculate significant differences. KESliL.T.5 - the reliability of the evaluated tests are in the range of rtt = 72 - .98. and therefore altogether acceptable - the selectivity of the tests is also acceptable in general ( exception. test .4 for Tennis plavers). - the great intraindividuell differences between runners with turns to the left and right. as well as between the players within a team illustrate the necessarity from precise diagnostics A few number of training sessions will eliminate individual deficits
