the ground reaction curve (grc) is a vital component of the convergence-confinement method, which possesses many applications in the underground space designs. it defines a relation between the tunnel wall deformations and the ground pressure acting on the tunnel walls. generally, grc includes descending and ascending branches. according to many researchers, the descending branch trend for the ...

Why is maximal running speed reduced on curved paths? The leading explanation proposes that an increase in lateral ground reaction force necessitates a decrease in peak vertical ground reaction force, assuming that maximum leg extension force is the limiting factor. Yet, no studies have directly measured these forces or tested this critical assumption. We measured maximum sprint velocities and ...

The aim of this study was to determine the effect of the time between measures on ground reaction force running variability; 15 healthy men (age1⁄4 23.8 3.7 years; weight1⁄4 72.8 7.7 kg; height 174.3 8.4 cm) performed two trials of running 45 minutes at 9 km/hr at intervals of seven days. The ground reaction forces were recorded every 5 minutes. The coefficients of variation of indicative param...

BACKGROUND The first peak of the knee adduction moment curve during walking has been shown to be a good clinical surrogate measure of medial tibiofemoral joint loading and osteoarthritis. Defining the relative contributions of the variables that dictate the knee adduction moment, such as center of mass, center of pressure, vertical ground reaction force, and knee adduction angle (i.e. lower lim...

objectives: foot and ankle problems are common complications in rheumatoid arthritis disease. gait pattern such as normal foot and ankle rocker is impaired in patients with rheumatoid arthritis. rocker sole as an external shoe modification is commonly prescribed in this pathology. the aim of this study was to investigate the effect of rocker shoe on vertical ground reaction force parameters dur...
