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.

The Role of Biomechanical Parameters and Muscle Activity during Eccentric and Concentric Contractions in Vertical Jump Performance

(ProQuest: ... denotes formula omitted.)IntroductionMany studies investigated the performance of vertical jump in its different types, especially from the biomechanical performance considering that

Comparison of the validity of Hill and Huxley muscle–tendon complex models using experimental data obtained from rat m. soleus in situ

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.

Muscle preactivation control: simulation of ankle joint adjustments at touchdown during running on uneven ground.

The GM regulation is more adequate for adjustment in the ankle joint, enabling sufficient regulation of angle and stiffness.

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 was

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 the

The unique action of bi-articular muscles in complex movements.

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.

Role of mono- and biarticular muscles in explosive movements.

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.
