Hypotheses concerning the influence of changes in the design of the human musculoskeletal system on performance cannot be tested experimentally. Computer modelling and simulation provide a research methodology that does allow manipulation of the system's design. In the present study this methodology was used to test a recently formulated hypothesis concerning the role of the biarticularity of the gastrocnemius muscle (GAS) in vertical jumping [Bobbert and van Ingen Schenau, J.

TLDR
It seems that long compliant tendons in the plantar flexors are an elegant solution to the problem of maximizing jumping performance, as they allowed for a higher power output at the ankles. Expand
The role of the biarticular hamstrings and gastrocnemius muscles in closed chain lower limb extension.
TLDR
It is argued that an analysis that is based upon considering the effect of the biarticular muscles on the segments that they span (rather than their effect on joint rotations) can be illuminating and demonstrates the importance of considering the effects of muscles onThe body as a whole, not just on the joints they span.

Dependence of human maximum jump height on moment arms of the bi-articular m. gastrocnemius; a simulation study
In this study the dependence of maximum jump height on moment arms of m. gastrocnemius at the knee and ankle joint was investigated, using a forward dynamic simulation model of the humanExpand
Comparison of the validity of Hill and Huxley muscle–tendon complex models using experimental data obtained from rat m. soleus in situ
TLDR
It is concluded that Huxley and Hill MTC models are equally valid with respect to mechanical behaviour, as they yield similar predictions of rat soleus muscle force, under physiological contraction conditions. Expand
Muscle preactivation control: simulation of ankle joint adjustments at touchdown during running on uneven ground.
TLDR
The GM regulation is more adequate for adjustment in the ankle joint, enabling sufficient regulation of angle and stiffness. Expand
Mechanical and muscular factors influencing the performance in maximal vertical jumping after different prestretch loads.
TLDR
Slow prestretches at the onset of muscle activation under relatively low average stretch loads, as observed during counter movement jumps and drop jumps from 0.3 m, prevented excessive stretching of the muscle fibres in relation to the tendon length changes, and conserved the potential of the fibres to produce positive work during the following muscle-tendon shortening. Expand
THE EFFECT OF COORDINATION ON VERTICAL JUMPING PERFORMANCE
The purpose of this study was to gain a better understanding of why coordination, or the timing of muscle actions, affects performance in vertical jumping. A forward dynamic simulation model wasExpand
Mono- and Biarticular Muscle Activity during Jumping in Different Directions
This study examined the role of mono- and biarticular muscles in control of countermovement jumps (CMJ) in different directions. It was hypothesized that monoarticular muscles would demonstrate theExpand
The effects of ankle restriction on the multijoint coordination of vertical jumping.
TLDR
Investigation of the effect of ankle restriction on the coordination of vertical jumping and the influence of energy transfer through m. Expand
Optimizing the Distribution of Leg Muscles for Vertical Jumping
TLDR
This work examined how high a human could jump if muscle volume were optimized for jumping, and determined how the optimal parameters improve performance, using a four-link inverted pendulum model of human vertical jumping actuated by Hill-type muscles. Expand

On the role of biarticular muscles in human jumping.
TLDR
The authors challenged the idea that jumping pcrformance could be increased by the unique biarticular action of the GAS by comparing simulated jumps with a four-segment model, jointed together with frictionless rcvolutes, and driven by 8 musculo-tendon actuators. Expand

Coordination in vertical jumping.
TLDR
For vertical jumping the relationships between muscle actions, movement pattern and jumping achievement, and the EMG-pattern to the purpose of the push-off, were investigated to maximize the effective energy (Ey) of the mass center of the body (MCB). Expand
The unique action of bi-articular muscles in complex movements.
TLDR
It is suggested that the bi-articular character of the gastrocnemius muscle enables the knee extensors to continue to deliver work which is transported to the ankle where it is used for plantar flexion. Expand
Role of mono- and biarticular muscles in explosive movements.
TLDR
It is concluded that power transport is essential in the execution of explosive movements because it allowed the biarticular muscles to transport energy in a proximodistal direction and allowed them to decelerate the angular velocities of the hip and knee joints without losses due to eccentric contractions. Expand
Optimal muscular coordination strategies for jumping.
TLDR
A detailed analysis of an optimal control solution to a maximum height squat jump, based upon how muscles accelerate and contribute power to the body segments during the ground contact phase of jumping, finds that the biarticular gastrocnemius increases jump height by as much as 25%. Expand
SPACAR: a software subroutine package for simulation of the behavior of biomechanical systems.
TLDR
On the basis of the results obtained on a test problem simulated with both SPACAR and DADS, it is concluded that both methods are accurate; DADS is much faster. Expand
The constrained control of force and position in multi-joint movements
TLDR
It is suggested that different processes may underlie the organization of the control of mono- and bi-articular muscles. Expand
An optimal control model for maximum-height human jumping.
TLDR
Qualitative comparisons between the predictions of the model and previously reported experimental findings indicate that the model reproduces the major features of a maximum-height squat jump, including limb-segmental angular displacements, vertical and horizontal ground reaction forces, sequence of muscular activity, overall jump height, and final lift-off time.
