9th grade students' understanding and strategies when solving x ( t ) problems in 1D kinematics and y ( x ) problems in mathematics We design, validate, and administer a 24-item test to study student understanding of linear functions in 1D kinematics [x(t)] and mathematics [y(x)] in th...
Plantar fasciitis is one of the most common musculoskeletal injuries in runners and jumpers, with a higher incidence in females. However, mechanisms underlying sex-associated differences in its incidence remain unclear. This study investigated the possible differences in landing and jumping kinematics and...
THE USE OF FUNCTIONAL TESTS TO PREDICT SAGITTAL PLANE KNEE KINEMATICS IN NCAA‐D1 FEMALE ATHLETESAnterior cruciate ligament, kinesiology, Margaria‐Kalamen, triple hop, vertical jumpBackgroundLanding with the knee in extension places increased loads on ligamentous restraints at...
Within each subject, the hip joint experienced the greatest torque because of the relatively large horizontal moment arm of the bar (dominant mass in the system) to this joint. In all subjects, the magnitude of the mass lifted, and not the technique, was the primary determinant in the inter...
Gender differences in joint biomechanics during walking: normative study in young adults. The effect of gender on specific joint biomechanics during gait has been largely unexplored. Given the perceived, subjective, and temporal differences in w... DC Kerrigan,MK Todd,UD Croce - 《American Journal...
the authors also discuss the technology effect influence of time,the speed,the distance and the angle parameter in jumping serve.The purpose is to provide the scientific basis for the later training and the teaching,and provide the reference for raising the Chinese female volleyball athletes in ...
To achieve a curved ball trajectory, players should take a wide approach angle, point the support foot to the right of the intended target (for right-footed players), swing the kicking limb across the face of the goal, and impact the ball with the foot moving upwards and in an abducted ...
3D meniscal kinematics and deformation with knee flexion and loading: A novel in-vivo MRI study of the kneePassed quietly and without dissent1 in 1990,... D Watling,D Williams,GM Whatling,... 被引量: 0发表: 2015年 In-vivo evaluation of the kinematic behavior of an artificial medial meni...
Objectives:To study the character of arm-swing movement in power spike for young men's volleyball players.Method:Seven young men's volleyball players performed an arm-swing movement in power spike,which were synchronously analyzed by surface electromyography and kinematics.Result:The results indicated ...
(ii) the Lagrangian spectrum at high frequency of particles moving in small scale eddies and the effects of the time dependence of the eddies; (iii) the relative velocities Δu and the separation distance l between pairs of particles, to find the decorrelation time scales of Δu and the ...
