The effect of plyometric exercises on some aspects of muscle strength and snatch performance among lifters

Abstract

Weightlifting depends on strength, muscular and explosive ability, and correct skill performance, which is represented by lifting the highest weights in the snatch and clean. There are many aspects of muscular strength, including maximum and explosive strength, which are among the basic components of lifters.

Recent changes have occurred in the process of preparing lifters, especially in the part related to developing muscular and explosive strength, and one of the most recent changes is the practice of plyometric exercises in different methods. The researchers chose two training methods for plyometric exercises, one of which was performing the exercises using body weight, and the other was performing the same exercises by adding additional weight to the body weight. Hence, the importance of the research became clear, so that these exercises were different and varied within the training program and intensified with training units for lifters to develop aspects of muscular strength, which is of utmost importance in achievement. For lifters, especially the snatch, which is the first lift in competitions. This is to supplement the training process in weightlifting, improve their physical abilities, and develop their skill and achievement performance in a scientific manner.

The research aims to identify the differences between the pre- and post-tests between the two experimental and control groups for each of the variables of aspects of muscular strength and snatch achievement among lifters.

And to identify the rate of development for the two experimental groups due to the effect of plyometric exercises for all research variables.

And to identify the size of the effect for the two experimental groups on the effect of plyometric exercises on all variables of aspects of muscular strength and achievement among lifters.
