E-mail address: [email protected] (P. Edouard) Opinion/Feedback Hamstring muscle injury is the main injury related to athletics, but also other sports including acceleration and sprints, with important consequences (time loss of sport and re-injury risk). In a prevention approach, a better knowledge of risk factors and mechanisms of these lesions seem relevant, and it can pass through a better understanding of the biomechanical and muscular determinants of performance in sprint and acceleration. The ability to produce a horizontal force on the ground [i.e. orienting the total push backward (or ground force reaction forward)], and to do so despite the increase in running speed, is an important determinant of sprint performance. The hamstring muscles seem to play an important role in this key ability. Evaluation of mechanical properties of sprint including the force-velocity profile and maximum theoretical horizontal force (FH0) and maximum theoretical speed (V0) in sprint is possible in real-practice conditions with simple tools. Studies have reported a change in the forcevelocity profile and decrease in FH0 following hamstring muscle injury, which could be a consequence of the injury. This approach to analyse the hamstring propulsion function at a maximum acceleration sprint looks promising given the very functional and ecological character in a field evaluation, close links between the function and strength of hamstring and the horizontal force sprint, and these encouraging preliminary scientific results. This force-velocity profile evaluation could be used to guide the return to sprint and allow

authorisation to maximum sprint after hamstring muscle injury, but also to screen athletes at risk of hamstring muscle injury.

E-mail address: [email protected] (J. Caquot) Objective The jumper-Knee is common among basketball player’s with adverse consequences on the practice. For the sake of prevention, it seems interesting to study its importance in the younger categories. The aim of the present study was to collect epidemiological data on pain below patella in France hope Championship basketball. Material and methods We conducted a sectional survey by questionnaire, a given day. We sent ten questionnaires to the attention of players and a questionnaire to the attention of the coaches of the 18 participating training centers at the Championship of France pro A hope. The survey took place between November and December 2015. Questionnaires were developed with the help of professionals and tested by 10 players and 1 coach of the regional championship before being sent.
