Vertical jump and shot speed, efficacy and accuracy in water polo
We have evaluated water polo vertical jump and shooting success determinants, their interplay, identified its main variables and proposed a predictive model. Twenty two sub elite players (23.23+ 7.22yrs and 13.0+ 5.4yrs of experience) were tested for absolute vertical jump (146.41+ 6.96cm) relative jump (considering trunk and upper limb length) and handgrip strength (54.97+ 5.26kgf) Shooting speed (radar) efficacy and accuracy were also assessed. Players with higher trunk and upper limb length were those who had less elevation out of the water (R=0.60, p=0.004) and relative jump and body mass were the explanatory main variables of absolute vertical jump (r2=0.41, p=0.003) Shot speed to goal was 18.66+ 1.37 and 18.37+ 1.27m.s 1 (with and without previous displacement) with players attaining 50.0+ 33.7 and 59.09+ 34.02% of shot efficacy. Towards canvas target, shot speed was 17.47+ 1.61 and 17.26+ 1.69m.s 1, and players were 24.6+ 18.5 and 27.3+ 20.0% accurate. Handgrip strength was highlighted as the main variable for shot speed situations and predictive models were found, which did not occur regarding efficacy and accuracy 'without displacement' However, a model has been found for shot accuracy toward canvas 'with previous displacement' (r2=0.34; p=0.003) in which handgrip strength is focused. Results found are important to monitoring and better plan the training process for the enhancement of team performance.
