Onset of Muscle Soreness (DOMS) for players of athletes at the National Center for Sports Talent Care

Abstract

The first chapter included an introduction to the research, which included the role of performing regular resistance exercises with high intensity (75-95%) of an individual’s maximum performance for one reptation max (1RM), which works to develop the muscular strength in general of the muscles of young weightlifters and the importance of using PBFR bands that accompany performing low-intensity resistance exercises that were added to the training curriculum approved by the sample coach. The research problem lies in the effect that performing regular resistance exercises with high intensity (75-95) % of the individual’s maximum performance for (1RM), Which causes the phenomenon of Delayed Onset of Muscle Soreness (DOMS), as a result of tissue damage, which is accompanied by the occurrence of local inflammation in the muscle tissue, which negatively affects the process of rapid recovery and the return of the production of muscle strength to the muscles of the selected arms. The objective of the research is the effect of using bands to restrict blood flow in a practical way (PBFR), which accompanied to performance of low-intensity resistance exercises on the Delayed Onset of Muscle Soreness (DOMS) for the research sample under study. As for the study hypotheses, they stated that there are no statistically significant differences between the results of the pre- and post-tests of the experimental research group due to the effect of using bands to restrict blood flow in the practical way (PBFR) which accompanied to performance of low-intensity resistance exercises on the indicator of (DOMS) for the sample under study. The third chapter included the use of the experimental method, while the design was one-group, in which the main experiment was applied to the experimental research sample, which consisted of (8) young weightlifters from the weight center, one of the national centers for caring for sports talent, and the dependent variable was measured before and after the effect of the independent variable. The fourth chapter, the statistical portfolio program (IBM SPSS Statistics 23.0) was used in order to extract the statistical coefficients required in the current study, and the results were discussed based on relevant reliable scientific sources. In the fifth chapter, the researchers concluded that there is a positive effect using bands that restrict blood flow in this way. The process (PBFR), which is accompanied by performing low-intensity resistance exercises, reduces the index of (DOMS), by reducing the occurrence of tissue damage in the muscle fiber.
