| Abstract | ||
| The purpose of this study was to examine the relationship between the rate of force development with two legs jump (2LEG) and one leg jump from three steps running (1LEG) for Egyptian handball national team players. Fifteen elite male handball players from the Egyptian handball national team (age=22.8 ± 2.1 y; height=187.1 ± 7.2 cm; mass=88.9 ± 10.1 kg) volunteered in this study. Each player performed three trials of vertical jump (VJ) with two legs and three trials one leg jump from three steps running (1LEG). The best trial was selected for analysis. Wireless accelerometer data (Beanair AX-3DS 24G) were processed using Smoothing Moving Average filter (Sigview 2.5 software) to calibrate Peak of Force (PF) and Time to Peak force (TPF) with a force platform data (Bertec). The results showed that rate of force development (RFD) has a relationship between the two legs jump (2LEG) and one leg jump from three steps running (1LEG) performance. The rate of force development (RFD) had a relationship with 2LEG and 1LEG performance. In high level handball, the rate of force development is the most important ability in most game situations; it gives the player an advantage to accelerate, decelerate or jump and shooting in less time. Therefore it can be used as an indicator for efficiency for all power activities and as a differential parameter between different classes of players in handball. | ||
