Effects of functional strength exercises on the performance level of some physical variables and defense skills of handball goalkeepers

The research aims to design a training program 
using functional strength training to identify:
1-The impact of the training of the functional force on some physical variables of the goalkeeper of the goal (muscle strength, reaction speed compatibility balance flexibility agility) under consideration.
2- The impact of the training of the functional force on the level of performance of some of the defense skills of the goalkeeper of the game (defensive move defense of the arm foot defense arm defense foot defense of the arm and foot) under consideration.
Research hypotheses:
1-There are statistically significant differences between the pre-measurement and post-measurement of the experimental group in the physical variables in question for the benefit of telemetry.
2-There are statistically significant differences between the pre and post-measurement of the experimental group in the defense skill variables under consideration in favor of the post.

Functional strength exercises
It is an integrated, multi-level (frontal, cross-sectional) movement that includes acceleration, stabilization and deceleration, with the aim of improving motor ability, central force (ie, spine and mid-body) and neuromuscular efficiency. (19: 87.(
