Publication date: April 2019Source: Science & Sports, Volume 34, Issue 2Author(s): N. Olivier, F. DaussinSummaryObjectiveEvaluate the shoulder isokinetic strength of high-level female water polo players.MethodsTwo groups were compared: a control group of noncompetitive females (n = 10), and members of the French women's national water polo (n = 18). Isokinetic measurements focused on the shoulder internal rotators (IR) and external rotators (ER), the evaluations were realized at 60°·s−1 and 240°·s−1 in the concentric mode and at 60°·s−1 in the eccen...
