Prevention in Volleyball Players

Around ten teams will be recruted among the clubs in the Province of Liege. They will be divided into two groups (blind): an intervention group and a control group.

Each month, both groups will be asked to fill in a form with the potential injuries they experienced during the past month.

• Intervention group :

All the teams included in the intervention group will be asked to follow a warm-up prevention program (about 15 minutes) at least twice a week, at the beginning of the training session.

At the beginning of the season, one experimenter will go to the different clubs in order to present the program, to explain the exercises and to correct the players while doint the exercises.

During the season, the same experimenter will go to the clubs at regular intervals to make sure that the players are well doing the program and to assess the compliance.

• Control group :

The objective of the control group is to estimate the prevalence of shoulder injuries in a group without any prevention implementation. The players of this group will jus have to answer the monthly questionnaire about the potential injuries they experienced during the previous month.
