An efficient Euler-Adams hybrid integration scheme for simulating on the computer discrete-value controlled large-scale neuromyoskeletal system models is presented. If, as discussed in the model, the differential equations describing the recruitment

The concept of the centre of percussion of rigid bodies, and that of its conjugate point, the locus of restraint, is considered to be an important feature in the design and construction of tennis rackets. Using theoretical analysis, computer simulati

The validity and reliability of the jumping ergometer method for evaluating performance in two-legged vertical countermovement and serial rebound jumps were investigated. The internal segmental and nonvertical energy flow components for drop jumps we

A two-dimensional impact probability density distribution for tennis rackets has been established. It was found that the center of this distribution, and therefore the most likely candidate for a preferred impact center, is the nodal point of the fun

The relationship is investigated between the apparent coefficient of restitution and the losses in preimpact kinetic energy of the ball for tennis rackets whose handles are constrained by various clamping modes. The complete energy balance equation o

Several biodynamical properties of tennis rackets such as vibrational characteristics, direction control, and the coefficient of restitution depend critically on the constraining mode of the handle. The racket response to ball impact differs fundamen

In recent years, it has been recognized by many researchers (e.g., Lehman 1990) that the study of oversimplified models of both the skeletal and the muscular subsystem may produce totally unrealistic and even fundamentally erroneous results (see also

The development of noninvasive techniques for the determination of biomechanical body segment parameters (volumes, masses, the three principal moments of inertia, the three local coordinates of the segmental mass centers, etc.) receives increasing at

A new method in human motion analysis is presented for overcoming the problem of the shifting of skin-mounted position markers relative to the skeleton. The present version of the method is based on two-dimensional video processing and involves the r
