Abstract: Compared to bilateral landings, male and female recreational athletes performed unilateral landings with significant differences in knee kinematic and EMG variables. Female athletes landed with increased knee valgus and VGRF compared to males during both types of landing.

“…However, data analysis of the female population in the study by Hanson et al (18) and Tillman et al (6) suggest that the gender may be an important variable concerning the activation of this musculature, constituting in a potential factor for injury in the ACL in women (10) . Besides gender, other factors which can have influenced on these differences between studies, such as training status (29) , the sport practiced by the tested individuals (30) and the motor conducts used in the test, since to some studies used running with change of direction (18,31) and other different jump and landing types (1,7,17,29) . However, even if all variables were controlled, there could have been discrepancy in the results of the studies in the literature, since the study by Fagenbaum and Darling (17) demonstrated high variability of the activation of the biceps femoris between trials, corroborated in the present study through the high variation coefficient (table 1), which generates the hypothesis of different strategies of motor coordination based on the absence of global strategies, making the individual strategies necessary (32) .…”

“…Subsequently, each athlete performed three landings with one lower limb and three landings with the two lower limbs for the myoelectric activity (EMG). Data collection was performed in the dominant lower limb (7,9) . The jumps were randomly performed to minimize the possible fatigue or learning process effects.…”

“…Among the studies that considered jump-down, some of the important ones addressed only the landing strategy. The landing phase is where the subject attains balance, so the landing mechanisms should be carefully observed [32][33][34][35][36]. The motion capture system, force plates, and electromyography (EMG) are useful for assessing balance.…”
