This research aims to explore more deeply the impact of functional training on improving the physical abilities of combat sport athletes. By analyzing and evaluating various related studies, the results of this research will provide in-depth insight into the effectiveness and relevance of functional training in the context of athlete development in combat sports. This type of research is a literature review, by searching for articles via Google Scholar. The search results found 5 articles from 2022 - 2023 that were in accordance with the topic of this research (Table 1). The types of combat sports that have been identified are judo, martial arts, wrestling, sambo, taekwondo. The conclusion of this research is that functional training is a training method that focuses on improving the performance of combat sport athletes because it involves certain muscles or movements according to the type of combat sport. The type of training applied in this training can be adjusted to the athlete's condition or periodization phase, of course with clear objectives. So the advantage of functional training is that it can adapt from other training methods such as body weight, machine assistance or other equipment. However, from further analysis of the sample and research results, it appears that athletes who undergo functional training are athletes who are trained or have had a lot of competition experience. The opinion of the results of this research is that functional training is specifically for athletes who are experienced or have had a lot of training hours.
