Cohorts and Interventions

Group / Cohort	Intervention / Treatment
female players; national team players	Other: advise for exercices given by team staff; To respond to questions asked: it is not the investigator who decides on the intervention, but the daily team staff (e.g. trainer, coach, PT,.....). So no predetermined intervention is provided
male players; national team players	Other: advise for exercices given by team staff; To respond to questions asked: it is not the investigator who decides on the intervention, but the daily team staff (e.g. trainer, coach, PT,.....). So no predetermined intervention is provided

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
2D and 3D joint angles of different movements together with kinetics	kinematics and kinetics with regard to gait, running, jumping and arm movements. This means for example joint angles (measured by 3D motion analyses data, 2D measurement data) and kinetics (joint moments, pressure plate measurements) Time frames: these data will recorded by one measurement session. For information of clinicaltrials.gov (also other outcome measures): at this point it really is an observational study. It is a kind of "service project" for an elite athletes team. Advice is provided, but not as is meant within a real clinical trial. It might evolve to such a project, but at this state it is not the case.	1 day

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
muscle strength	isokinetic measurements (expressed in Nm)	1 day
muscle strength	isokinetic measurements (ratio agonist/antagonist as for example ratio between knee flexors/extensors) Time frames: these data will be recorded during one measurement session. This is during same session as for primary outcome measure.	1 day
joint stability	nominal scale (good, poor)	1 day
joint control	nominal scale (good, poor)	1 day
prevalence injury past	interview (frequency/percentage of occurrence)	1 day
prevalence injury present	interview (yes/no)	1 day
(segmental) length	Meter	1 day
weight	Kg	1 day
Body mass index	Kg/m²	1 day
