They were divided into two groups, one experimental and the other a control group, each group consisted of (12) players. The researcher used the following statistical treatments: the mean - the standard deviation - the median - the torsion coefficient - the "T" test - the correlation coefficient - the equation of improvement rates. Among the most important findings and conclusions: - The use of cluster training is positively influences development of the rebound force index (vertical - horizontal) and Speed , speed FootWork to cadet of Taekwondo The researcher recommends the importance of: - use of cluster training for cadit in Taekwondo because of its influence on the rebound force index (vertical - horizontal) and Speed , speed FootWork - The need for taekwondo trainers to use cluster training during their implementation of training programs because of its effective impact.
