Throwing in handball is the most decisive action in success or failure in the offensive phases of the game. In order to study and analyse this, it is necessary to measure the throwing speed during the competition. This research aimed to achieve two objectives; the first one, to compare the average throwing speed between the first and the second half of the organized offensive phase during the 2013 Men´s World Handball Championship. The second, to describe the throwing speed between the first and the second half during the 2013 Men´s World Handball Championship with respect to its effectiveness (a goal/not a goal). Throwing speeds were registered in 47 matches in the 2013 World Handball Championship using a radar (StalkerPro S.A., Plano), with a frequency of 100 Hz and a sensitivity of 0.045 m/sec-1, fixed on a tripod behind the goal. Statistical analysis was carried out using SPSS software (version 22). The Kolgomorov-Smirnov test was used to check normality and homogeneity. The results show non-parametric variables. Subsequently, the variables were analysed with the Mann-Whitney U-test. Statistically significant differences were not found in the average throwing speed between the first and the second half of the matches of the World Championship, nor in its throwing effectiveness. These results show that fatigue is not a variable that influences the throwing
The studies that analyse the throwing speed in the different positions on the field in high-performance handball are scarce. These contributions are nonexistent if the analysis refers to the throwing speed during the competition. For this reason, the objective of this research was to analyse the throwing speed in the central positions during the matches at the 23rd Men´s World Handball Championship. Three thousand two hundred and forty-two throws in the matches of this championship were analysed. The throwing positions tested were the left back, the centre back and the right back. A radar (StalkerPro S.A., Plano), with a frequency of 100 Hz and a sensitivity of 0.045 m/s1, fixed on a tripod behind the goal, was used. Analysis was performed using SPSS software (version 22). The variables were analysed with the Mann-Whitney Utest. Statistically significant differences were not found among all the throws carried out by the participating teams in the championship. There are statistically significant differences in the throwing speed between the best 8 teams with respect to the other 8 teams of the championship in the central position in the first half of the match (p>0,05), both for the total number of throws and the effectiveness (goal/not a goal). The best teams obtain higher throwing speed in the central position, but there is no difference in relation to
Este estudio describe la estructura antropométrica de los mejores jugadores de waterpolo españoles en las categorías júnior y sénior; y en segundo lugar, pretende determinar si existen diferencias antropométricas, en la composición corporal y en el somatotipo entre ambas categorías. La muestra empleada en este estudio fueron 23 jugadores de la selección española de waterpolo, de ellos, 9 jugadores de categoría júnior y 14 sénior. Las diferencias estadísticas más significantes, entre ambas categorías, son en aquellas variables que guardan relación indirecta con los niveles de fuerza y con la experiencia. Los jugadores de la categoría júnior presentan un somatotipo mesomórfico equilibrado, mientras que los jugadores de la categoría sénior presentan un somatotipo endo-mesomórfico.
