| Abstract | ||||
| This research aims to identify the effectiveness of core muscle Exercises on the muscle strength level (legs, trunk, and arms) and the performance level of the jump shooting skill for female handball players, as well as some biomechanical variables associated with the skill performance (performance stages time distribution, the body’s movement course horizontal displacement value, the shooting hand movement horizontal displacement value, the body’s gravity center height on the vertical axis at the elevation moment value, the elevated foot at the body launch moment vertical velocity components value, the shooting arm at the ball release moment horizontal velocity components value, the fixed shooting leg, the free leg, and the elevated foot joints angular change value, some body positions and parts angular change values percentages). The researcher used the descriptive approach through biomechanical analysis of the jump shooting skill, and the experimental method of one-group design on a sample of (7) female national players in the Helwan University team for handball, who performed (3) shooting attempts, before and after the application of core muscle Exercises. and the researcher used strength and muscle ability tests, and skill level tests for the jump shot skill. The Exercises program consisted of (30) units for (10) weeks period, with (3) Training units per week, and a capacity of (60) minutes per unit. The results showed improvement in the biomechanical variables (under study), strength and muscle ability measurements (legs, trunk, and arms) and the jump shooting skill performance of the research sample players. | ||||
