In the literature, it has been reported that the mechanical output per leg is less in two-leg jumps than in one-leg jumps. This so-called bilateral deficit has been attributed to a reduced neural… Expand
Is the effect of a countermovement on jump height due to active state development?
PURPOSE To investigate whether the difference in jump height between countermovement jumps (CMJ) and squat jumps (SJ) could be explained by a difference in active state during propulsion. METHODS… Expand

The purpose of this study was to gain insight into the control strategy that humans use in jumping. Eight male gymnasts performed vertical squat jumps from five initial postures that differed in… Expand
Which factors determine the optimal pedaling rate in sprint cycling?
INTRODUCTION Mechanical power output in sprint cycling depends on pedaling rate, with an optimum at around 130 revolutions per minute (rpm). In this study, the question is addressed if this optimal… Expand
Consequences of ankle joint fixation on FES cycling power output: a simulation study.
INTRODUCTION During fixed-ankle FES cycling in paraplegics, in which the leg position is completely determined by the crank angle, mechanical power output is low. This low power output limits the… Expand
The merits of a parallel genetic algorithm in solving hard optimization problems.
A parallel genetic algorithm for optimization is outlined, and its performance on both mathematical and biomechanical optimization problems is compared to a sequential quadratic programming… Expand
Is energy expenditure taken into account in human sub-maximal jumping?--A simulation study.

- 1 February 2008
This paper presents a simulation study that was conducted to investigate whether the stereotyped motion pattern observed in human sub-maximal jumping can be interpreted from the perspective of energy… Expand
Are fast interceptive actions continuously guided by vision? Revisiting Bootsma and van Wieringen (1990).

In the first part of lifting movements, the trunk movement is surprisingly resistant to perturbations. This study examined which factors contribute to this perturbation resistance of the trunk during… Expand
Forward Dynamics of Two-Dimensional Skeletal Models. A Newton-Euler Approach
Mathematical modeling and computer simulation play an increasingly important role in the search for answers to questions that cannot be addressed experimentally. One of the biggest challenges in… Expand
