Primary Outcome Measures

Name	Time	Method
<p>The Visual Analogue Scale (VAS) for pain will be used as the main study outcome<br /><br>in both parts of the study. With this measure subjects indicate on a continuous<br /><br>line between two end points their level of pain. The VAS pain scale is a valid<br /><br>and reliable measure of chronic and acute pain intensity (Bijur, Silver, &<br /><br>Gallagher, 2001) (Downie et al., 1978).<br /><br><br /><br>In the first part, the primary study parameter is the VAS pain score after ten<br /><br>single leg decline squats. In the second part of the study, the primary study<br /><br>parameter is the difference between the baseline and the intervention week in<br /><br>the average score on the VAS pain scale during sports.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>In the first part of the study, the secondary study parameter is the VAS pain<br /><br>score after the maximal vertical jump test and the triple hop test.<br /><br>Furthermore, the height in meters of the highest jump during the maximal<br /><br>vertical jump test for each condition and the distance in meters that is<br /><br>covered by three jumps during the triple hop test are considered secondary<br /><br>study outcomes.<br /><br><br /><br>In the second part of the study, the difference in average VAS pain score<br /><br>between the baseline week and the intervention week in the two hours after<br /><br>sports and the next morning are secondary study parameters. The difference in<br /><br>sports participation (the number and duration of training/matches and missed<br /><br>training/matches a week) between the baseline week and the intervention week is<br /><br>also a secondary study outcome.</p><br>
