Brief Summary

This project is a consequence of the research chair project studying the same phenomenon in adult volleyball players. The project will make use of and be part of the routine medical screening that is taken by the young players of the first degree of the Leuven Volleyball School, Belgium. All young players must undergo a routine medical investigation and movement screening. This is obliged by the law. The current project will use these data. Outcome parameters will be used to advice the trainer staff of the school to adjust their training interventions. This is normal routine too as the involved medical department has been advising the school for many years. Players will be followed up for 6 weeks. After those 6 weeks, the movement screening will be repeated to evaluate the change in the different outcome parameters. This last screening is not part of a normal routine as players normally are investigated more in a subjective way. The medical team and school want to change that routine.

Data will be used to further improve training modalities and sports performance and reduce injury risk in these young athletes.

Primary Outcome Measures
NameTimeMethod
Change of joint mobilityDifference between baseline and 6 weeks

Mobility will be assessed by using goniometer measurements (degrees of movement)

Change of strengthDifference between baseline and 6 weeks

Strength will be assessed by using handheld dynamo-meter data (Newton)

Change in lower limb joint angles during a single leg drop vertical jumpDifference between baseline and 6 weeks

Movement quality is measured using joint angles (trunk, pelvis, hip, knee, ankle)

Change in lumbopelvic stability scoreDifference between baseline and 6 weeks

Lumbopelvic stability is scored using 9 clinical tests (Bend knee fall out, Active straight leg raise, prone knee bend, sitting knee extension, standing bow, pelvic tilt, one leg stance, backward rocking, forward rocking). Each test is given a score between 0 (poor performance) and 2 (good performance) adding up to a total score of 18.

Change in lower limb joint angles during a drop jumpDifference between baseline and 6 weeks

Movement quality is measured using joint angles (trunk, pelvis, hip, knee, ankle)

Change in balance scoreDifference between baseline and 6 weeks

Stability is measured using the score on the Star Excursion Balance Test (numeric score on balance scale)

Secondary Outcome Measures

Baseline data on joint mobility (joint angles), strength (N), balance (Star Excursion Balance Test Score, lumbopelvic control scores) and joint angles during a drop jump and single leg drop vertical jump) are all visualized on a web diagram per athlete
