| Abstract | ||
| Biomechanics aims for analyzing sports performance for the ability of error correction to achieve peak performance and success levels. The aim of this study was to compare between the anticipation time and kinematic factors in the movement of high level and beginner female goalkeepers’ center of mass when making a long-distance throw in handball. The sample group was composed of 14 female goalkeepers "7 high level and 7 beginners" and field players as shooters. A force platform was used to measure the force of the goalkeepers’ reaction movements, while the throwers’ movements were recorded with high-speed cameras. The high level female goalkeepers began to move 193 ± 67 ms before the ball was released, with a 67% success rate of ball interception. The beginner female goalkeepers began their movement 209 ± 127 ms with a 24% success rate. The time taken by high level female goalkeepers to begin a vertical movement of their CM, relative to the moment of the ball’s release, was less than the time taken by beginner goalkeepers (77 ± 70 vs. 141 ± 108 ms respectively). The analysis of the velocity and movement indicates that expert high level female goalkeepers waited longer time before moving than do inexperienced beginner female goalkeepers.. | ||
