Abstract EN

The objective of this study was to know the effectiveness of using high intensity interval and repetitive training exercises in developing Using high-intensity interval and repetitive training exercises to develop specific strength yield for the lower body parts (strength endurance, speed strength, explosive power) and its impact on the aim accuracy from high jumping position U21 hand-ball players of Wadi Seli team - Chlef.

the sample members were picked by the intentional method and consisted of (20) players of the same age, weight, length, and specific strength tests, and it was shown that there are no statistical significance differences for these specifications.

Then they were divided into two groups (10) players each.

The study procedures included setting two training programs using repetitive training and high intensity interval training, the researcher used the experimental approach that which suitable for our research.

Pre-tests were ran on the groups (strength endurance, speed strength, explosive power and aiming accuracy tests).

After (06) weeks of training according to the program, post-tests were run, and It was found that there are statistical significance differences at the significance level 0.

05 in favor of the experimental group.

The results of high intensity interval training were better than those of repetitive method for strength endurance, and there were also statistically significant differences for experimental group in the method of repetitive training in the development of speed-strength and explosive strength with an ence of statistical significant differences in the strength endurance for this group.
