Importance of Jumping Ability in Handball Throwing Speed and Accuracy

Throwing the ball to score a goal in handball is a critical action for success in offensive play. Speed and accuracy are two determining factors for successful throws. While there is substantial research on the importance of these factors, discrepancies exist regarding their relationship. This study aims to analyze the impact of jumping ability on throwing speed and accuracy across different competitive levels in handball. Thirty-five male handball players were recruited from amateur and professional levels. Jumping ability was assessed and throwing speed and accuracy were measured using a high-performance sports radar. Significant differences (p < 0.05) were found between amateur and professional groups in countermovement jump (CMJ) and throwing speed jump. The comparative analysis revealed significant differences in throwing speed and in correct and incorrect throws, with large to very large effect sizes. Pearson's r correlation indicated significant correlations between throwing speed jump and CMJ, countermovement jump left (CMJL), and countermovement jump right (CMJR), and between throwing speed deficit and CMJL in the total sample. The results show that professional handball players exhibit higher throwing accuracy and speed compared to amateurs. Throwing speed and accuracy are positively correlated with performance in male handball players.
