The spring-mass model, representing a runner as a point mass supported by a single linear
leg spring, has been a widely used concept in studies on running and bouncing mechanics …

It is not presently clear whether mathematical models used to estimate leg stiffness during
human running are valid. Therefore, leg stiffness during the braking phase of ground contact …

When humans and other mammals run, the body's complex system of muscle, tendon and
ligament springs behaves like a single linear spring ('leg spring'). A simple spring-mass …

Human running can be modelled as either a spring-mass model or multiple springs in
series. A force is required to stretch or compress the spring, and thus stiffness, the variable of …

Spring-mass models have been used to characterize running mechanics and leg stiffness in
a variety of conditions, yet it remains unknown how running while carrying a load affects …

The goals of this study were to examine the following hypotheses:(a) there is a difference
between the theoretically calculated (McMahon and Cheng, 1990. Journal of Biomechanics …

Purpose By applying a simple, linear mass-spring model to running, the normalized leg
spring stiffness (Kleg), the normalized effective vertical stiffness (Kvert), and the mass …

Stiffness describes the resistance of a body to deformation. In regard to athletic performance,
a stiffer leg-spring would be expected to augment performance by increasing utilisation of …

Mechanical stiffness (vertical, leg and joint stiffness) can be calculated during normal human
movements, such as running and hopping. Mechanical stiffness is thought to influence …

Leg stiffness is a common parameter used to characterize leg function during bouncing
gaits, like running and hopping. In the literature, different methods to approximate leg …
