The research aims to identify the effect of using massage methods during the training period on some indicators of muscle fatigue for decathlon players. The researchers used the experimental approach with an experimental design for one experimental group using pre-post measurement, representing the research population of decathlon players under 18 years of age who are registered with the Egyptian Athletics Federation in Training season 2022/2023 AD, and the research sample was chosen intentionally, as the number of members of the total research sample reached (7) players, (2) who are members of the exploratory study sample, and thus the number of members of the basic research sample became (5) one experimental group, and the most important indicated The results indicate that the proposed hospital program had a positive impact on all the variables under study (blood pressure - pulse - dehydrogenase enzyme - lactic acid). The highest percentage of improvement was in the variable (lactic acid) by (22.83) and the lowest percentage of improvement was in the variable (pulse after exertion). (With a ratio of (1.20), there is an improvement in the post-measurement over the pre-measurement in the lactic acid variable as a result of using massage methods.
