الملخص EN

The development and improvement of personal achievement a main goal for each athlete and coach, the successful coach derives its success through briefed on all that is new, and this study was conducted to develop the recipe(muscle power) and know the rang of effect in the development of achievement for the snatch in weightlifting, and weightlifting game its individual and numbering games affected by the ways and means of modern training that contribute to raising the level of achievement and achieve high numbers during competitions and various tournaments and depth jump exercises by different heights was used in order to develop muscle power.

The aim of the research to detect the following: 1- Preparation depth jump exercises from different heights.

2- Identify the effect depth jump exercises from different heights on the muscle power (for legs and arms).

3- Identify the effect depth jump exercises from different height on the achievement in lifting the snatch.

The researcher had hypothesized the following: 1- There are significant differences in muscle power for legs and arms between the pre-test and post-test, and for the sake of post-test.

2- There are significant differences in achievement (snatch lifting) between pre-test and taught post-test, and for the sake of post-test.

3- There are significant differences between the controller group and the experimental and for the sake of experimental group.

The researcher used the experimental method for suitability nature of the research, the research community has be from the team Erbil weightlifting players for the youth and adult population (12) lifters, either research sample was included (10) lifter chosen by intentional way divide to two groups experimental and controller groups and equal and unequal ruled out as a researcher (2) lifter for the implementation of exploratory testing.

The researcher had reached the following conclusions: 1- depth jump exercises resulted to develop experimental group in all the research variables (the muscle power of legs and the muscle power of the arms) which was the difference between the two tests the pre-test and post-test dimensional for post-test.

2- There has been no development of muscular power of arms and achievement (snatch) for the control group between pre-test and posttest And researcher recommended the following: 1- Focus on the muscle power training for lifter mainly because it connects the power and speed in the one dynamic movement.

2- Addition depth jump exercises to coaches program to develop the muscle power for weightlifting lifter in the preparation period the public and private.

And insert these exercises in training programs throughout the season training according the preparation levels
