The effect of two methods of ballistic resistance training on some aspects of upper body strength in the long jump for Specialized School athletes

Abstract

The importance of the current study lies in it conducting a comparison between two training methods of ballistic resistance for the school athletes specialized in the long jump. The first method use the medical balls with different weights, while the second method use the ballistic tapes with different resistances on the basis of the original tape length and its percentage of stretching. The goal of the research is to explore the effects of these two methods to develop specific aspects of the muscular strength of the arms. The study sample was intentionally selected from the Specialized School athletes for gifted and strong saliva in the long jump Nineveh Branch, which numbered 10 athletes, and was divided randomly into two experimental groups with (5) athletes for each group. Equivalence was made for the two study groups in my tests (explosive force, and the distinctive force of velocity for the arms). The probability value appeared respectively (0.608) and (0.667), which is not significant, indicating that the two groups are equal. The ballistic resistance curriculum was initially implemented as part of the main section of the trainer curriculum unit for a period of 9 weeks. The sample conducted the tests in the pre and post measurements (the test of throwing a medical ball with the arms to the farthest distance), (and the test of throwing the medical ball against the wall at a distance of (1.5 m) continuously for 10 seconds) The results of the study showed that there were significant differences in favor of the ballistic tapes, with a marked improvement in the explosive power and the force characterized by the velocity of the arms. The study concluded that the method of ballistic resistance using tapes is distinguished from the method of using medical balls. The study focused in its recommendations on long jump trainers to use ballistic style exercises with tape for the arms at the end of the special preparation period and to combine them with the trainer's training program.
