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.

Outcome Measures

Primary Outcomes (6)

• Change of joint mobility

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

  Difference between baseline and 6 weeks

• Change of strength

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

  Difference between baseline and 6 weeks

• Change in balance score

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

  Difference between baseline and 6 weeks

• Change in lower limb joint angles during a single leg drop vertical jump

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

  Difference between baseline and 6 weeks

• Change in lumbopelvic stability score

  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.

  Difference between baseline and 6 weeks

• Change in lower limb joint angles during a drop jump

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

  Difference between baseline and 6 weeks

Secondary Outcomes (2)

• Individualized web diagram of all outcome measurements

  Baseline

• Number of injuries

Interventions

Training intervention OTHER

Based on the baseline screening, which is part of the normal prevention routine within the school, all athletes are given individual advice with regard to points of attention within training. For example: those athletes with reduced balance, will get more balance training. Intervention is individual as said and will be guided and supervised by the physical trainer and medical staff of the school.
