Research aim :
The research aims to determine the effect of training on the muscle groups of strength and balance, both static and dynamic, on the skill performance level of kickboxing players
Search assumptions :
- There are statistically significant differences between the means of the measurements (pre-test - post-test) in muscle strength measurements, favoring the means of the post-test measurements for the sample under study.
- There are statistically significant differences between the means of the measurements (pre-test - post-test) in both static and dynamic balance, favoring the means of the post-test measurements for the sample under study.
- There are statistically significant differences between the means of the measurements (pre-test - post-test) in skill performance, favoring the means of the post-test measurements for the sample under study.

Research method :
Research procedures :
The experimental method was used with a one-group design employing pre-test and post-test measurements.
sample of research :
The research community includes kickboxing players in the Cairo area at the Military Institution Club, aged between 18 and 20 years, who are registered with the Egyptian Kickboxing Federation for the year 2022/2023. The size of the primary sample reached 8 players, and 2 players were used in the exploratory study, making the total sample size 10 players.
