Introduction: Despite of several diagnostic tools in sport, test results do not determine team line-up. There are obviously factors influencing match performance that cannot be measured yet. Nevertheless, diagnostics are essential for systematic training and its evaluation. In female soccer, a lack of money is responsible for insuffiecient testing. A sprint test with changes in direction is a typical test for team sport attendees and does not require an expensive setup. The aim of the current study was to modify a common sprint test setup by adding information about the speed profile. This could allow assumptions about the demands on the energy system and lower limb strenght. Methods: 26 female soccer players (playing in second or third German league) participated voluntarily in this study. As pretests, a field level test protocoll, a treadmill ramp test protocoll and a Counter-Movement-Jump (CMJ) were conducted. After a warm-up the participants performed an 80 m sprint with two changes in direction of 180 degrees. A LAVEG laser gun was used to gauge the speed profile and the alactice time was determined based on the model of Heck and Schulz (2002). Further parameters measured were heart rate, blood lactate concentration, maximal velocity and interims of the sprint. Results: The analysis showed a correlation between the interims of the sprint and the generated W/kg in the CMJ. A linear regression showed that at least 30 % of the variance of the sprint interims could be explained by the generated W/kg. In addition large differences between the alactic time could be observed. Discussion: The influence of the physical precondition seems to play a significant role concerning the sprint performance. Adapting a common sprint test protocol could easily help diagnosticians to get more information at lower expenses. Future research may enable scientists to identify different types of athletes concerning especially the use of the energy system. Therefore they could provide more appropriate training recommendations for coaches. ABSTRACT FROM AUTHOR
