通过对手球罚点球中的速度和角度的测量，研究了肌肉疲劳和不同场地位置的不同任务对这些变量的影响。对乌拉圭国家女子手球队10名运动员的抛球运动进行了平面二维运动学分析。考虑到比赛时间和球员的位置，使用配对样本t检验（p <0.05）分析球速和输出角度。在比赛的前半段，与后半段相比，速度明显更高（p = 0.0006）。根据场地位置的不同，速度也有显著差异（p = 0.00015），背部投掷比翅膀投掷快。投掷角度在比赛时间和位置上没有差异（分别为p = 0.43和p = 0.63）。比赛中速度的变化可能是由于肌肉疲劳增加的影响。发现这个变量的差异，根据现场的位置是一致的功能球员在比赛中进行。拍摄角度的微小变化被解释为不受肌肉疲劳影响的技术优势的指示。
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.
