Three-dimensional position data of nineteen elite male Malaysian badminton players performing a series maximal jump smashes were collected using motion capture system. A ‘resultant moments’ inverse dynamics analysis was performed on the racket arm joints (shoulder, elbow and wrist). Relationships between head speed peak joint moments quantified correlational analyses, inclusive Benjamini–Hochbe...

The acute respiratory distress syndrome in adults (ARDS) may complicate a wide variety of serious medical and surgical conditions, not all of which involve the lung directly. The pathogenesis remains unclear, but involves neutrophil recruitment to the alveoli and inflammatory pathway activation leading to increased permeability of the alveolarcapillary membrane and disordered vascular control, ...

Wrist and elbow angular kinematics and racket acceleration at impact were measured in the tennis one-handed back-hand drive for three groups of players: Professionals with no history of tennis elbow (PRO), intermediates with no history of tennis elbow (- TE), and intermediates with a history of tennis elbow (+ TE). Electrogoniometer, strain gauge, and accelerometer signals were sampled for thir...

The collision of a ball with a baseball bat or a tennis racket is usually modeled in terms of rigid body dynamics, assuming that the hand exerts no impulsive reaction force on the handle during the collision. In this paper, a uniform aluminum beam was used as an idealized bat or racket, in order to examine both the rigid body approximation and the assumption that the hand force can be neglected...

In this work, a general definition of Convolution between two arbitrary Tempered Ultradistributions is given. When one of the Tempered Ultradistributions is rapidly decreasing this definition coincides with the definition of J. Sebastiao e Silva. The product of two arbitrary distributions of exponential type is defined via the Convolution of its corresponding Fourier Transforms. Several example...
