“…These phenomena may be induced by the geometry of the blades, which are supposed to prevent rotation of the foot to increase performance in sidestep and cutting maneuvers. Studies conducted with professional soccer players performing different motions and maneuvers by employing motion analysis and inverse dynamics models (Gehring, Rott, Stapelfeldt, & Gollhofer, 2007;Kaila, 2007) showed that studded and bladed cleats had no effect on the loads acting in the knee but influenced the player performance and perception to some degree (Mü ller Sterzing, Lange, & Milani, 2010). Direct measurements and comparisons of the rotational resistance of the different types of cleats are currently available (Andréasson, Lindenberger, Renströ m, & Peterson, 1986;Cawley, Heidt, Scranton, Losse, & Howard, 2003;Grund & Senner, 2010;Heidt et al, 1996;Torg & Quedenfeld, 1971;Villwock, Meyer, Powell, Fouty, & Haut, 2009), but these studies neither support nor reject the hypothesis that the cleat design has an influence on the stresses in the knee joint.…”
