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

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 2D and 3D joint angles of different movements together with kinetics [ Time Frame: 1 day ]
    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.


Secondary Outcome Measures :
  1. muscle strength [ Time Frame: 1 day ]
    isokinetic measurements (expressed in Nm)

  2. muscle strength [ Time Frame: 1 day ]
    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.

  3. joint stability [ Time Frame: 1 day ]
    nominal scale (good, poor)

  4. joint control [ Time Frame: 1 day ]
    nominal scale (good, poor)

  5. prevalence injury past [ Time Frame: 1 day ]
    interview (frequency/percentage of occurrence)

  6. prevalence injury present [ Time Frame: 1 day ]
    interview (yes/no)

  7. (segmental) length [ Time Frame: 1 day ]
    Meter

  8. weight [ Time Frame: 1 day ]
    Kg

  9. Body mass index [ Time Frame: 1 day ]
    Kg/m²
