“…38 For the DVJ, the participant was positioned on top of a 31-cm box and instructed to drop off the box, with both feet leaving the box simultaneously and each foot landing on a separate force platform (AMTI, Watertown, MA), then to immediately execute a maximal effort vertical jump towards an overhead target (FIGURE 1). Athletes frequently injure their ACL while landing from a jump 5,15 ; therefore, the landing phase of the DVJ was used for analysis. In addition, the DVJ task was examined extensively in a population of healthy athletes to determine predictors of initial ACL injury in these populations.…”

“…Not surprisingly, the incidence of ACL injury is relatively high in sports involving a high frequency of landing, decelerating and rapid changes of direction such as basketball, netball, handball and volleyball (Arendt and Dick, 1995;Griffin, Angel, Albohm, et al 2000). The incidence of non-contact ACL injury has been reported to be 6 to 8 times greater in females than in males competing in the same sports (Arendt and Dick 1995;Chandy and Grana 1985;Ferretti, Papandrea, Conteduca, et al 1992;Gray, Taunton, McEnzie, et al 1985;Gwinn, Wilkens, McDevitt, et al 2000;Lindenfeld, Schmitt, Hendy, et al 1994;Malone, Hardaker, Garrett, et al 1993).…”

Abstract.The aim of the study was to investigate lower limb coordination and stiffness in five male and five female university volleyball players performing block jump landings. Coordination was assessed using angle -angle plots of the hip -knee, knee -ankle and hip -ankle joint couplings and discrete relative phase (DRP) of right -left joint couplings (i.e. left knee coupled with right knee). Leg stiffness was calculated as the ratio of the change in vertical ground reaction force (GRF) to the change in vertical displacement of the centre of gravity between ground contact and maximum vertical GRF. Knee stiffness was calculated as the ratio of the change in knee joint moment to the change in knee flexion angular displacement between ground contact and maximum knee joint moment. Comparison of the DRP angles between left and right legs indicated reduced symmetry between the left and right legs in females compared to males which may indicate greater likelihood of ligament strain in females compared to males. Furthermore, females exhibited reduced stability in the coordination between the left and right knee joints than males. Males exhibited significantly greater absolute and normalised leg stiffness and significantly greater absolute and normalised knee joint stiffness during landing compared to females. In conjunction with the coordination data, this may indicate reduced dynamic stability of the leg in females compared to males which may contribute to the greater incidence of ACL injury in females compared to males.

“…Recently, injury of the ACL has been reported to be two to eight times higher in women than in men participating in the same sports. Previous studies have indicated noncontact mechanisms as the reason for ACL tears in women, which make these injuries even more perplexing [1,2,4,7,8,12,20].…”

We studied 16 women 21-23 years old with regular menstrual cycles (28±4 days) and no history of knee injury. From their basal body temperatures and the serum concentrations of estradiol and progesterone, the follicular, ovulatory, and luteal phases were delineated. Using a KT-2000 arthrometer, anterior displacement at 89 N and 134 N and anterior terminal stiffness (N/mm) at 134 N were measured two or three times every week over a 4-week period. Eight men 21-23 years old were also measured. In women the anterior displacement at 89 N varied between the follicular and the ovulatory phase and between the follicular and the luteal phase (P<0.05) and at 134 N between the follicular and the luteal phase (P<0.05). There were no statistical differences in the anterior displacement with time in men, nor in anterior terminal stiffness in either sex. We conclude that anterior cruciate ligament laxity in women might be dependent on the concentrations of hormones. et à 134 N entre la phase folliculaire et lutéale (p<0,05). Il n'y avait pas de différences statistiques dans le déplace-ment antérieur chez les hommes, ni dans la raideur terminale antérieure dans l'un et l'autre sexe. Nous concluons que la laxité du ligament croisé antérieur chez la femme peut être dépendante des concentrations hormonales. Résumé
