**5. Conclusions**

In conclusion, our study clearly demonstrated the importance of anthropometry, jumping performance, and maximal isometric strength to handball performance. In future sports practice, more emphasis should be given to handball-specific resistance training for players to gain more muscle mass of lower (legs and pelvis) and upper limbs (shoulders and arms), which will afterwards manifest in better jumping, sprinting, and shooting performance. Special consideration must be given to resistance training of pivots and goalkeepers to improve their muscle strength and shooting performance [2], as they were outperformed by wings and backcourt players. Furthermore, we also propose the routine inclusion of isometric measurement of shoulder and knee joint maximal torques to monitor changes of maximal muscle strength during the course of the handball season and to detect potential muscle imbalances, which may contribute to higher injury incidence. In line with this, more studies on elite and sub-elite handball players should be conducted to provide new practical evidence of the importance of isokinetic testing and to further determine several important aspects of physical performance in relation to handball shooting performance.
