The value of strength‐diagnostic for the structure of jump training in volleyball

The action height in volleyball is of crucial importance to the success in offensive situations such as attack and block. Apart from the time‐to‐contact requirement aligned course of motion (technique of jumping), a set of strength parameters have a performance‐diagnostic function. Therefore, more isometric and dynamic strength abilities were examined in connection to the jump strength performance. The collective consisted of 46 international women players. Beyond that, the changes of the ascertained strength parameters were evaluated in the season and in the long‐term development of individual cases. The conclusion can be drawn that common strength‐diagnostic procedures only supply the coach with information difficult to interpret and do not include direct information for organizing jump‐strength training. Jumping is obviously best trained and diagnosed by jumping.
