Kickboxing began during the 1970’s in the US, when the American karate practitioners had become very frustrated with the strict controls imposed on martial arts competitions that restricted full contact punches and kicks. Many questions were asked when the sport first began pertaining to the high risk of injury. Thus, safety rules were improved and imposed and had protective clothing introduced.
Because this is a relatively new sport, no long-term traditions exist. There has been changes and refinements during the past two decades to improve the sport. Competitors make use of all kickboxing kicks, punches, kick blocks, spring, shadow boxing, and also wood breaking; this is taught and applied with professional instruction.
