Does an instrumented treadmill correctly measure the ground reaction forces?
Since the 1990s, treadmills have been equipped with multi-axis force transducers to measure the three components of the ground reaction forces during walking and running. These measurements are correctly performed if the whole treadmill (including the motor) is mounted on the transducers. In this case, the acceleration of the treadmill centre of mass relative to the reference frame of the labor...
متن کاملForce treadmill for measuring vertical and horizontal ground reaction forces.
We constructed a force treadmill to measure the vertical, horizontal and lateral components of the ground-reaction forces (Fz, Fy, Fx, respectively) and the ground-reaction force moments (Mz, My, Mx), respectively exerted by walking and running humans. The chassis of a custom-built, lightweight (90 kg), mechanically stiff treadmill was supported along its length by a large commercial force plat...
متن کاملVariability of ground reaction forces during treadmill walking.
The purpose of this study was to investigate whether or not the neuromuscular locomotor system is optimized at a unique speed by examining the variability of the ground reaction force (GRF) pattern during walking in relation to different constant speeds. Ten healthy male subjects were required to walk on a treadmill at 3.0, 4.0, 5.0, 6.0, 7.0, and 8.0 km/h. Three components [vertical (F(z)), an...
متن کاملCOMPARING EFFICIENCY OF EXERCISE ON THE TREADMILL AND GROUND ON THE GROUND REACTION FORCES DURING WALKING IN PEOPLE WITH GENU VARUM
Background & Aim: Genu varum is one of the most common abnormalities of the knee joint in which the inner condyles of the femur move away from each other. The aim of the present study was to compare efficiency of exercise on the treadmill and ground on the ground reaction forces during walking in people with genu varum. Material & Methods: The present study was a quasi-experimental and laborat...
متن کاملNormalization of ground reaction forces.
The appropriateness of normalizing data, as one method to reduce the effects of a covariate on a dependent variable, should be evaluated. Using ratio, 0.67-nonlinear, and fitted normalizations, the aim of this study was to investigate the relationship between ground reaction force variables and body mass (BM). Ground reaction forces were recorded for 40 female subjects running at 3.7 +/- 0.18 m...
