BACKGROUND Increasing the coefficient of friction of the shoe-surface interaction has been shown to lead to increased incidence of anterior cruciate ligament (ACL) injuries, but the causes for this increase are unknown. Previous studies indicate that specific biomechanical measures during landing are associated with an increased risk for ACL injury. HYPOTHESIS At foot contact during a sideste...

PURPOSE Runners use uphill running as a movement-specific form of resistance training to enhance performance. However, the optimal parameters for prescribing intervals are unknown. The authors adopted a dose-response design to investigate the effects of various uphill interval-training programs on physiological and performance measures. METHODS Twenty well-trained runners performed an increme...

Over the years a number of high quality studies has established the effectiveness of external measures (tape, brace) and neuromuscular training for the prevention of ankle sprains. The general conclusion derived from these studies is that recurrent ankle sprains can be effectively prevented using any of these measures, and that measures are cost-beneficial. Nevertheless, despite the commonness ...

Idiopathic scoliosis (IS) is a class of paediatric spinal deformities that has historically posed a significant challenge to the orthopaedic and scientific community. Our understanding of the underlying mechanisms associated with the early progression to advanced stages that require surgical intervention is limited. Current clinical models of assessment provide limited insight into the biomecha...

This study examined relationships between three dimensional (3D) pelvis, hip and knee biomechanical measures in a bodyweight single leg squat and those same measures in a drop landing and a pre-planned 75° cutting manoeuvre. 40 field sports players with chronic athletic groin pain were recruited. There were no significant (p > 0.05) correlations between hip and pelvis measures in the SLS and th...

A biomechanical model constrained stochastic finite element framework has been developed to jointly estimate myocardium kinematics and material parameters from medical image sequence. In an extended Kalman filter formulation, we have observed that the augmented state error covariance matrix must be carefully chosen in order to avoid divergence. In this paper, we incorporate confidence measures ...

The biomechanical benefits (e.g., muscular activity) of slanted ergonomic mice have been comprehensively identified; however, their effects on task performance and subjective responses have not been fully investigated. The present study examined the effects of two slanted mice (slant angle = 30° and 50°) in comparison with a conventional mouse (slant angle = 0°) in terms of task performance (ta...

The use of a biomechanical model for human grasp modelling is presented. A previously validated biomechanical model of the hand has been used. The equilibrium of the grasped object was added to the model through the consideration of a soft contact model. A grasping posture generation algorithm was also incorporated into the model. All the geometry was represented using a spherical extension of ...

Since the anthropometric and biomechanical parameters role is effective in improving the quality of sports skills, researchers and sports scientists are interesting to identify and communicate between these factors. The purpose of this study was making relationship between some of anthropometrical and biomechanical parameter of girl swimmers in swimming breast strokes. Twenty girl Swimmers (mea...
