Abstract

The overhead throw in water polo is the most effective and frequently used method of propelling the ball and scoring goals. Related research has usually examined throws performed on land and this information is then adopted for modelling the overhead throw in water polo. However, the benefits derived from this method of performance modelling are doubtful since the throw performed in water differs markedly from the on-land version. This study sought to examine the relationship between muscular strength and morphology of elite water polo players (n=21) with overhead throwing velocity. An eight week, intervention strength training program comprising exercises using the `Nautilus system and emphasising upper body strength development was performed on one group of players. A control group, who did not supplement their regular swimming and game practice with specific strength training, were used for comparison. Significant relationships (p<0.01) with throwing velocity were found to exist for standing height, body mass, lean body mass, stem length, biacromical width, arm girth and forearm extension strength. Following the strength training intervention program no change in overhead throwing velocity was recorded for either the treatment or control group, although significant increases (p<0.01) in arm girth, mesomorphy and arm medial rotation strength were demonstrated by the treatment group alone.
