Skiing and snowboarding have become more acrobatic with terrain park jumps and other manmade features playing a prominent role in an increase in serious spinal cord injuries. Yet these jumps rarely, if ever, involve formal or detailed design or engineering. This paper presents a coherent theory and methodology for the design of ski jump landing surfaces. The motion of the skier center of mass i...
CONTEXT Rapid deceleration during sporting activities, such as landing from a jump, has been identified as a common mechanism of acute knee injury. Research into the role of potential sex differences in hip abductor function with lower extremity kinematics when landing from a jump is limited. OBJECTIVE To evaluate sex differences in hip abductor function in relation to lower extremity landing...
The neural circuitry and biomechanics of kicking in locusts have been studied to understand their roles in the control of both kicking and jumping. It has been hypothesized that the same neural circuit and biomechanics governed both behaviors but this hypothesis was not testable with current technology. We built a neuromechanical model to test this and to gain a better understanding of the role...
Women began contesting the 3000 m steeplechase during the 1990's using barriers of different dimensions than men. Whenever a new event is introduced for women, consideration should be taken as to whether different technique or training methods should be utilized. This study investigated three aspects of hurdling technique: 1) Differences in the ratio of the landing step to the penultimate step ...
BACKGROUND Patellar tendinopathy (PT) is a common degenerative condition in physically active populations. Knowledge regarding the biomechanics of landing in populations with symptomatic PT is limited, but altered mechanics may play a role in the development or perpetuation of PT. PURPOSE To identify whether study participants with PT exhibited different landing kinematics compared with healt...
UNLABELLED The repeal of the Direct Ground Combat Assignment Rule has renewed focus on examining performance capabilities of female military personnel and their ability to occupy previously restricted military occupational specialties. Previous research has revealed female Soldiers suffer a greater proportion of musculoskeletal injuries compared to males, including a significantly higher propor...
Higher side-to-side asymmetry among female athletes compared to their male counterparts during bilateral athletic tasks such as landing from a jump has been proposed as a potential source of non-contact knee injuries. However, the kinematic symmetry and potential sex differences during bilateral landings have not been examined. The purpose of this study was to evaluate lower extremity kinematic...
Objective: Limitation of ankle dorsiflexion range of motion as the most important risk factors for ankle sprain injury can cause disorder in neuromuscular control of muscles around the ankle. The aim of this study was to compare the onset of the activity of selected muscles around the ankle joint of those athletes with ankle dorsiflexion range of motion limitations with healthy Athletes during ...
