The influence of the force-velocity mechanical properties of upper limb on throwing performance in young experienced handball players

(Der Einfluss der mechanischen Eigenschaften von Kraft und Geschwindigkeit der oberen Gliedmaßen auf die Wurfleistung bei jungen, erfahrenen Handballspielern)

INTRODUCTION: Overarm throwing is considered one of the most critical actions in handball sports related to the gain of competition, which requires the players to throw as fast and accurately as possible to score a goal. It is well known that the overarm throw is a typical ballistics movement that requires the athlete to accelerate a given ball as much as possible to reach the highest throwing velocity in the shortest amount of time (1). Although previous studies have proposed fundamental methods for quantifying upper-limb explosive capacity, such as the ballistics bench press, the Force-Velocity (F-V) mechanical properties obtained during the ballistics bench press have not explored its association with the throwing performance. Thus, the present study aimed to investigate the F-V mechanical properties obtained during the ballistics bench press with a different type of throwing performance in handball players METHODS: Twenty-seven French national second-division male handball players (age: 20.0 ± 3.2 years, height: 180.5 ± 6.3 cm, weight: 73.9 ± 7.9 kg) volunteered for the investigation. Force-Velocity (F-V) mechanical parameters (i.e., theoretical maximal force [F0], velocity [V0], power [Pmax]) of the upper limb were obtained during the single-arm ballistics bench-press for the dominant arm according to the validated method (2). The throwing performance was assessed by the maximal standing and 3-step running throwing velocity using a Stalker ® ATS II radar gun. RESULTS: The simple linear correlation analysis found that the V0 was significantly correlated with standing throwing velocity (r2 = 0.51, f2 = 1.04, p < 0.001) and 3-step running throwing velocity (r2 = 0.46, f2 = 0.85, p < 0.001). Additionally, a significant correlation was found between the 3-step running throwing velocity and the Pmax (r2 = 0.18, f2 = 0.22). In contrast, no significant correlation was found between other mechanical properties and throwing performance. CONCLUSION: The main results of the present study showed the importance of the upper limb F-V profile assessment in predicting throwing performance, especially the V0. In short, the handball players revealed higher V0 during the ballistics bench press, which could also perform the faster-throwing performance. This finding demonstrated that the mechanical parameters obtained from the ballistics bench press should be used to evaluate the upper-limb explosive capacity and allow the coach to design the particular training session to improve the explosive capacity of the upper limb to enhance the throwing performance.
