ground reaction force

For example, during walking ground reaction forces start at the heel and finish near the big toe.

He opened the field of modern 'motion analysis' by being the first to correlate ground reaction forces with movement.

A higher flight phase results in a higher vertical ground reaction force.

These models become increasingly complicated when multiple joints or environmental factors such as ground reaction forces are introduced.

This decreases the ground reaction forces through the patella-femoral joint greatly.

In the above example, the ground reaction force coincides with the notion of a normal force.

At each tire contact patch there are ground reaction forces with both horizontal and vertical components.

If the ground reaction forces are measured separately for left and right leg in addition body imbalances during the motions can be analysed.

During this time the aircraft does not exert any ground reaction force on its contents, causing the sensation of weightlessness.

During the initial stage of sprinting, the runners have their upper body tilted forward in order to direct ground reaction forces more horizontallly.

Collisions of an animal's foot or paw with the underlying substrate are generally termed ground reaction forces.

An increase in running speeds causes increased ground reaction forces and elite distance runners must compensate for this to maintain their pace over long distances.

It was also found that the belief that one's shoes have increased cushioning had no effect on increasing or decreasing ground reaction forces during walking.

Force platform measures ground reaction force.

The process of walking recovers approximately sixty per cent of the energy used due to pendulum dynamics and ground reaction force.

In that situation, the accelerometer is subject to two forces: the gravitational force and the ground reaction force of the surface it is resting on.

During level running at a speed of 3meters per second the vertical ground reaction force reaches a peak of approximately 2.5 times BW.

Ground reaction forces (GRF) are exerted by the ground on the body in contact with it and reflect the body's acceleration.

In 1996, Messier and colleagues observed the differences in ground reaction forces between obese and lean older adults with osteoarthritis.

Additionally, runners are able to alter their maximum ground reaction force and leg acceleration when they see a graph of peak leg acceleration.

Browning and Kram in 2006 observed two groups (one obese and one non-obese group) of young adult's ground reaction forces across different speeds.

One could then predict that as speed increases, loads felt by the lower-extremity joints would increase as the net muscle moments and ground reaction forces increase.

When tight, instead of absorbing the ground reaction force transmitted up the limb as we walk or run, the force is conducted straight into the low back, causing problems.

He found that the landings and takeoffs in these two skills involved high ground reaction forces that were executed in an extremely quick and explosive manner.
