The White House is gearing up to host a UFC event as part of celebrations of 250 years of American independence. The fighters on the card are relying on body conditioning techniques that have been around for centuries to try to emerge victorious. Muay thai, karate and jiujitsu all use ancient practices that condition the body for their field.<\/p>\n\n\n\n

The human body over time, and under the right stresses and strains, can become more resilient to physical and physiological challenges. One of the key scientific principles here is Wolff\u2019s law \u2013 the idea that bone remodels itself in response to the loads placed on it. Studies have shown that in many sports the dominant limb develops denser bone than the non-dominant side. In martial arts, this effect is seen in both arms and legs.<\/p>\n\n\n\n

In muay thai, fighters condition their shins by kicking banana trees \u2013 whose soft outer layers and substantial bulk make them ideal for the purpose. The repeated impact gradually adapts the tibia to the forces generated by kicking.<\/p>\n\n\n\n

The tibia is the second-longest bone in the body. Like most bones in the body, it has a dense outer shell surrounding a cavity, crossed by tiny structural rods \u2013 a design that combines strength with minimal weight.<\/p>\n\n\n\n

The thickness of the tibia is greatest at the points between 40-70% of its length from top to bottom, the outer (cortical) layer of bone is, on average, between 4-6mm thick in males and 3-5mm thick in females. No studies have directly compared tibia thickness in combat athletes and non-athletes. But in 2004, UFC fighter Shaun Strickland posted an X-ray image of his legs on Instagram showing noticeably thicker bone cortices \u2013 visible evidence of what years of shin conditioning can do.<\/p>\n\n\n\n

Kick forces are high enough that opponents are warned against single-arm blocks \u2013 the impact can fracture the ulna, the longer bone in the forearm, which accounted for a quarter of all mixed martial arts (MMA) injuries in one study.<\/p>\n\n\n\n

Even ancient traditions such as iron arm and wing chun, which exploit Wolff\u2019s law to condition the forearms, may struggle to prevent these high-impact traumatic breaks.<\/p>\n\n\n\n

Many athletes in combat sports also train their hands and arms. A popular way to do this is rice gripping: submerging hands in buckets of rice and performing various exercises against the resistance. <\/p>\n\n\n\n
