The effect of training with a weight vest in terms of mechanical energy to developing some biomechanical indicators among specialized school athletes in the 100m event

Abstract

Trainers and researchers in the sports field usually search for everything new and modern to improve sports performance and training. The weight vest represents a modern trend in training, as exercise programs must be combined to suit the requirements of the sport practiced and take into account two important principles, the principle of muscle function and the principle of specificity, while improving neuromuscular compatibility. Maintaining the balance and stability of the body, and training with a weighted vest helps in accustoming the working muscles to performing at a speed higher than the ability of the players’ biomechanical variables, which prompted the researcher to study this problem and find successful solutions to it. The study aimed to prepare weight bra exercises and determine their effect on the biomechanical variables and kinetic energy of the players. The experiment was applied to a sample of (8) players from the Specialized School of Athletics in the 100 m event. The researcher assumed that there were significant differences in the research variables between the pre- and post-tests, and the researcher concluded that the weight bra had an effective effect. In improving biomechanical indicators and improving mechanical energy, the researcher recommended the necessity of adopting weight-bearing chest exercises in other track and field events.
