Abstract

The research aims to:

1. The effect of phosphonate storage variation training on flexibility in weightlifting athletes.
2. The effect of phosphonate storage variation training on regular lifts in weightlifting athletes.

The researcher used the experimental method using a two-group equivalent approach, where the two groups were equivalent in all conditions except for the experimental variable, which affected the experimental group to reveal the difference between them.
The researcher defined the research community as the (18) weightlifters from the Hashemite Club and Al-Madhita Club in Babil Governorate. The research sample was intentionally selected and divided into two groups: an experimental group and a control group, each containing (9) weightlifters. This was done to ensure their cooperation in a manner that served the research purpose. In order to begin with a single starting point, and for the experimental method to have an impact on creating differences between the two groups, the researcher conducted a homogeneity and equivalence test. The researcher conducted pre-tests on the research sample (18 weightlifters). The researcher also developed exercises to develop the research variables (under study) for the experimental group. The training loads prepared for the phosphogyne storage variation training with weights were applied during the special preparation period. The researcher concluded:
- Phosphagen storage variation training significantly impacted the development of maximum strength due to its inclusion of maximum intensity and high repetition, which led to this development.
- The development of maximum strength created a good foundation for developing flexibility by utilizing the training loads used in phosphogyne storage variation training.
- This led to no significant differences between the research sample members in the research variables under study.
The study recommended:
 

1. Emphasis should be placed on developing weightlifters and developing systematic scientific programs for this purpose.
2. Evaluating the performance of weightlifters using quantitative and qualitative kinetic analysis, taking this into account when developing training programs.
