DEVELOPMENT OF VERTICAL GROUND REACTION FORCE AFTER HIP SURGERY
Journal of Biomechanics, 2012Human walking as a method of locomotion, enabling individuals move from place to place, is completely unique throughout the animal kingdom and strictly specific to species Homo sapiens sapiens [Dungl, 2005]. This study deals with the development of the vertical walking dynamics after hip surgery. An essential role after the Total hip arthroplasty (THA)

Vertical ground reaction force spectral analysis for fatigue assessment
2017 Fourth International Conference on Advances in Biomedical Engineering (ICABME), 2017In this paper, we propose a novel fatigue assessment technique using Vertical Ground Reaction Force (VGRF) signals acquired during ultra-marathon running. To achieve that goal, we performed frequency-domain on singlechannel VGRF signals on different time intervals during ultra-marathon running and tracked the features' variation. Our method was applied

Vertical ground reaction forces: objective measures of gait following hip arthroplasty
Gait & Posture, 2001After hip arthroplasty, many patients continue to exhibit abnormal gait patterns. The purpose of this study was to compare the vertical ground reaction forces of a group of 27 individuals who have undergone hip arthroplasty with a group of 35 normal control subjects. Specific force measures were determined from vertical ground reaction forces collected

Vertical Ground Reaction Force during Water Exercises Performed at Different Intensities
International Journal of Sports Medicine, 2013The aim of the present study was to compare the peak vertical ground reaction force (V-GRF(peak)) and impulse of women performing water aerobic exercises at different intensities in aquatic and dry land environments. 15 young women performed 1 session in each environment consisting of 3 water aerobic exercises (stationary running, frontal kick and ...

Effect of Functional Fatigue on Vertical Ground-Reaction Force in Individuals With Flat Feet
Journal of Sport Rehabilitation, 2013Context:Flat foot is one of the lower extremity deformities that might change kinetic variables of gait. Fatigue is one of the factors that can alter the vertical ground-reaction force (GRF). The effect of a fatiguing condition on vertical GRF has not been documented in individuals with flat feet.Objective:To examine the fatigue effect on vertical GRF ...

Simulation of the influence of sports surfaces on vertical ground reaction forces during landing
Medical & Biological Engineering & Computing, 2003In many biomechanical analyses, the vertical ground reaction force (GRF) is measured by force plates. However, if force plates are fixed on elastic surfaces, the force signals have low-frequency oscillations superimposed. The question arises, as to whether this oscillation results from the response of the athlete to the surface properties or from the ...

The Effect of Exertion and Sex on Vertical Ground Reaction Force Variables and Landing Mechanics
Journal of Strength and Conditioning Research, 2016The purpose of this investigation was to determine how exertion and sex affected a variety of vertical ground reaction force (VGRF) parameters during a jump-landing task, including peak VGRF, peak VGRF asymmetry, loading rate, and loading rate asymmetry.
