الملخص EN

The target of the study was to identify the effect of weight training in Different Proportions on the muscular balance of flexor and extensors muscles of the arms and the effectiveness of skill performance of the boxers.

The experimental method was used on an intentional sample of boxing players at Al-Raaed Sports Club in Saudi Arabia under 19 years old.

The basic study sample consisted of (6) boxers.

Weight training was used at various percentages during the special preparation period within their training program for 10 weeks.

After the completion of weight training exercises in different percentages, the post measurements were carried out for the study sample, statistically processing the data and discussing the results.

Conclusion: - Weight training in different proportions increased the strength of the flexor muscles of the forearm of the left arm of the boxing players to 30.7 kg, increased the strength of the extensor muscles to 27.2 kg, increased the strength flexor muscles of the forearm of the right arm of the boxing players to 36.8 kg, and increased the strength of the extensor muscles to 33.3 kg which improved muscular balance between them.

- Weight training in different proportions of flexor and arm muscles helped improving the aggressive behavior coefficient by 0.263 degree and the defensive behavior factor by 0.217 degree and the tactical activity factor by 0.480.

Recommendation:  Using weight training in different proportions of the flexor and extensor muscles of the arm according to the strength of each muscle to improve muscular balance among them within the training programs of the boxers under investigation.
