Age effect v juniorskom tenise

Abstract

The first publications about the theory of the age effect (theory of the influence of age) appeared in sports science in the 80´s of the last century. Though it was not as long as the last few years we have encountered with a research of this particular topic more regularly. The theory is based on the assumption that the athletes born at the beginning of the calendar year are, mainly in the junior age, more successful than later born athletes. This has been shown in many studies especially in ice hockey, soccer, tennis but also in other sports. This theme hasn´t been revealed in Czech kinanthropology yet, in priciple of which we aim to present using carried out on the elite junior female players. The purpose of this study was to verify the influence of the age effect on the participants of the World Junior Tennis Finals (WJTF - tennis teams Championships U14) from 2007 to 2011.
