Abstract:
The current research aims at improving the throwing distance of female shot putters through designing a specific training program based on biomechanical variables and identifying its effects on the digital record of shot put. The researchers used the experimental approach (one-group design) with pre- and post-measurements and the descriptive approach (case analysis). For biomechanical analysis, “Fadia Saad Ibrahim”, an international athlete who is Egypt’s champion, All Arabs Champion and holder of African third rank, was chosen for analyzing her performance. The researchers chose (8) shot putters from Kafr Al-Shaikh Sportive Club. Only the best two trials of each athlete were analyzed and therefore (16) trials were analyzed. Results indicated that the specific training program based on biomechanical analysis has led to statistically significant differences between pre- and post-measurements in favor of post-measurements on the following variables: Projection angle and velocity, altitude of projection point, duration of pushing phase, digital level. Beginning of glide phase: angles of knee and hip joints, Resultant velocity of thigh, shank, trunk and CG. Resultant momentum of shank and trunk. End of glide and beginning of push: hip and knee joints’ angles, knee angular velocity, resultant velocity of upper arm, thigh, shank, foot, trunk and CG. Resultant acceleration of trunk and CG, Resultant force of shank and trunk, CG momentum. End of pushing: elbow, hip and knee angles. knee angular velocity. Resultant velocity of forearm, upper arm, thigh, shank, trunk and CG. Resultant acceleration of forearm, thigh and trunk, resultant force of thigh and trunk. Momentum of forearm, thigh, trunk and CG.
