Angle and speed in female handball penalty throwing: Effects of fatigue and player position
Abstract:The speed and angle of ball throwing in handball penalty were measured and the effects of the muscular fatigue and the differential tasks implied in the different field positions on these variables were studied. The ball thrown by ten players of the female Uruguayan national handball team were 2-D kinematically analysed in the lateral plane. Ball speed and output angle were analysed taking into account the match time and the player's position, either back or wing, using paired sample t-test (p<0.05). A significantly higher speed (p=0.0006) during the first half of match time, compared to the second, was found. Significant difference in the speed according to the position in the field was also warranted (p=0.00015), with backs throwing faster than wings. The throwing angle showed no differences for match time and position (p=0.43 and p=0.63, respectively). The variation in speed during the match could be due to the effect of the increase in muscular fatigue. The difference found for this variable according to the field position is congruent with the function players carried out during the match. The small variations in the shot angles are interpreted as indicative of technique predominance not affected by muscular fatigue.
