The effect of strength exercises by decentralization stretching (p.n.f) on some elements of physical fitness for the skill of shooting from jumping for young handball players

Abstract

The purpose of this paper is to preparing decentralization stretching (p.n.f) exercises in some elements of physical fitness for the jumping skill of young handball players, identifying the effect of decentralization  stretching (p.n.f) on some elements of physical fitness for the shooting skill of young handball players, and identifying the superiority of the two groups (experimental and control) in some elements of physical fitness for the skill of shooting from jumping for young handball players. The researchers used the experimental method in the manner of two equal groups for his belief that it is the best and most appropriate way to solve the problem presented in the research. One of the most important results reached by the researcher is that: Stretching, and decentralization (p.n.f) exercises have a positive effect in developing some elements of physical fitness (Kinematic stretcher, instantaneous strength, Speed  characteristic  strength   of the muscles working on them for the skill of shooting from jumping in handball), the amount of development, and some elements of physical fitness, (Kinematic stretcher, instantaneous strength, Speed characteristic strength) in the experimental group that used, stretching exercises (p.n.f) was greater, compared to the control group. One of the most important recommendations recommended by the researchers is that: The use of stretching decentralization (p.n.f) exercises in a contraction-relaxation (CR) manner, which has a significant impact on developing some elements of physical fitness for handball players, youth, especially strength and flexibility, and using stretching decentralization (p.n.f) in one way, CR on another skill of handball.
