AnotationThe most common sports injury is ACL injuries (anterior cruciate ligament). In the world, the incidence of ACL injury is 1/3000 per year and 70% of these injuries are caused during sports activities (Hart & Štipčák, 2010). The greatest incidence of injuries in women is between 16 and 18 years of age (Yu, Kirkendall, Taft, & Garret, 2001; Shea, Pfeiffer, Wang, Curtin, & Apel, 2004). Female adolescents who participate in jumping, cutting and pivoting sports suffer ACL injuries at a four- to sixfold greater rate than male participating in the same sports (Hewett, Lindenfeld, Riccobene & Noyes, 1999). 70% of ACL injuries are non-contact injuries (McDaniel, Rasche, Gaudet, & Jackson 2010; Myklebus, Maehlum, Engebretsen, Strand, & Solheim 1997). ACL rupture occurs in 2/3 of cases during non-contact situations involving cutting maneuvers or landing (Ford, Myer, & Hewet, 2003). Literature is inconsistent from point of view of LCA injury. A number of authors suggest that ACL injury occur between 17 - 50 ms after initial contact (Krosshaug et al., 2007; Withrow, Huston, Wojtys, & AsthonMiller, 2008). The knee joint is in the low flexion range (0° - 30°) during injury (Beynnon et al., 1995; Ford et al., 2003). Players can solve the same motor task (cutting maneuvers, landing) by diferent way in the risk interval shortly after initial contact (Zahradník, Jandačka, Uchytil, Farana, & Hamill, 2016). There is therefore assumption, that players may have different risk probability of LCA injury depending on the way of solving the movement task. Currently it is unknown, that the way of solving relates to incidence of LCA injury.
