“…Despite those differences, studies have shown that most combat sports can be characterized as high-intensity, intermittent sports (Campos, Bertuzzi, Dourado, et al, 2012;Artioli, Gualano, Franchini et al, 2009;Franchini, Del Vecchio, Matsushigue et al, 2011;Terbizan & Selievold, 1996;Del Vecchio, Hirata, & Franchini, 2011). Consequently, injury risk had been consistently high in these athletes (Kobayashi, Kanamura, Koshida et al, 2010), even if the International Olympic Committee initiated and developed the injury and illness surveillance system during the 2008 Beijing and 2012 London Olympics (Junge, Engebretsen, Mountjoy et al, 2009;Engebresten, Soligard, Steffen et al, 2013).
