The Effects of Different Strength Training Methods on Muscle Strength and Explosive Power Performance in Combat Sports Athletes: A Systematic Review and Meta-Analysis
This systematic review and meta-analysis of 28 randomized controlled trials demonstrates that various strength training methods significantly enhance muscle strength and explosive power in combat sports athletes, with compound training proving most effective for strength and core training for explosive power, while also revealing distinct performance benefits for ground-based versus stand-up combat sports.

In the high-stakes world of combat sports, from the mat of a wrestling match to the ring of a boxing bout, victory often hinges on two physical qualities: the ability to push or pull with immense force, and the ability to unleash that force in a split second. Athletes in these disciplines need raw strength to control an opponent or hold a position, but they also need explosive power to strike, kick, or throw with speed and impact. For decades, coaches and trainers have debated the best way to build these traits. Some swear by heavy lifting to build a foundation of maximum strength, while others argue that jumping and throwing drills are the only way to teach the body to move fast. The reality is that combat sports are not all the same; a judoka grappling on the ground faces different physical demands than a boxer throwing punches while standing. Until now, there has been no clear consensus on which training methods work best for which type of fighter, leaving many athletes to guess at the most effective path to improvement.
A team of researchers set out to solve this puzzle by gathering and analyzing data from twenty-eight different scientific studies involving over six hundred combat athletes. They looked at a wide variety of training programs, ranging from traditional weightlifting and explosive jumping exercises to specialized core stability work and complex combinations of both. By comparing the results across these studies, they could determine not just if strength training works, but exactly which methods produce the biggest gains in strength and explosive power for different types of fighters. Their findings offer a clear roadmap for how athletes should train based on the specific demands of their sport.
The analysis confirmed that strength training, in almost any form, significantly improves both muscle strength and explosive power in combat athletes. However, the type of training that yields the best results depends heavily on whether the athlete competes in a standing or ground-based discipline. For fighters who spend most of their time on the ground, such as judo practitioners, wrestlers, and mixed martial artists, the most effective method for building raw strength was found to be complex training. This approach involves alternating between heavy resistance exercises, like lifting heavy weights, and explosive movements within the same session. This method proved superior for increasing maximum strength, likely because it teaches the nervous system to recruit more muscle fibers while also maintaining the ability to move quickly.
In contrast, athletes who compete in standing events, such as boxing, taekwondo, and fencing, showed the greatest improvements in explosive power when they focused on core strength training. This type of training targets the muscles of the trunk and abdomen, which act as the central hub for transferring force from the legs to the arms or from the hips to the striking limb. By strengthening this central area, these athletes were able to generate faster strikes and more powerful kicks. While standing fighters also benefited from other methods, the data indicated that a strong core was the single most important factor for enhancing their ability to explode into action.
The researchers also looked at how different training styles affected specific parts of the body. They found that all forms of strength training improved upper and lower body strength, but the gains were more pronounced in the upper body for ground-based fighters, who rely heavily on gripping and pulling opponents. For standing fighters, the training translated more effectively into explosive power in the lower body, which is essential for rapid footwork and generating momentum for strikes. The study also examined emerging training techniques, such as blood flow restriction training, which uses light weights with restricted circulation to stimulate muscle growth, and velocity-based training, which adjusts weight based on how fast an athlete moves. While these methods showed promise, the traditional approaches of complex training for strength and core work for power remained the most reliable choices based on the current evidence.
Ultimately, the study suggests that a "one-size-fits-all" approach to training is less effective than a tailored strategy. Athletes and coaches can now use these findings to design programs that match the specific physical requirements of their sport. Ground-based fighters should prioritize complex training to maximize their ability to control opponents with raw force, while standing fighters should focus on core stability to refine the speed and impact of their attacks. By aligning training methods with the unique demands of the sport, combat athletes can build the specific physical tools they need to perform at their highest level.
