Inferred Influence of Human Lateral Profile on Limb Load Asymmetry during a Quiet Standing Balance Test [PDF]

open access: yes, 2008
Although the identification and characterisation of a participant's lateral profile during quiet standing have not received much research attention, they have the potential to greatly extend our understanding of upright stance stability control.

Comparison of vertical ground reaction forces during overground and treadmill running. A validation study

open access: yesBMC Musculoskeletal Disorders, 2012
Background One major drawback in measuring ground-reaction forces during running is that it is time consuming to get representative ground-reaction force (GRF) values with a traditional force platform.

Sexual Dimorphism Impact on the Ground Reaction Force Acting on the Mediolateral Direction During Level Walking: Hip Abductor Muscle Biomechanics and Its Correlation to GRF Moment Arm

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
The female pelvis morphology represents an evolved compensation between two opposing needs: a broad pelvis enough to deliver a sizeable brained offspring while remaining narrow enough to allow for effective bipedal gait.

A robust sagittal plane hexapedal running model with serial elastic actuation and simple periodic feedforward control [PDF]

open access: yes, 2013
In this article we present a sagittal plane, sprawled posture hexapedal running model with distributed body inertia, massless legs and serial elastic actuation at the hips as well as along the telescoping legs.

Ground reaction force sensor fault detection and recovery method based on virtual force sensor for walking biped robots [PDF]

open access: yes, 2013
This paper presents a novel method for ground force sensor faults detection and faulty signal reconstruction using Virtual force Sensor (VFS) for slow walking bipeds. The design structure of the VFS consists of two steps, the total ground reaction force (

Ground Reaction Force in Sit-to-stand Movement Reflects Lower Limb Muscle Strength and Power in Community-dwelling Older Adults

open access: yesInternational Journal of Gerontology, 2015
Background: Ground reaction force parameters in a sit-to-stand (STS) movement can be used to evaluate lower extremity function. Few reports, however, are available on whether the ground reaction force parameters in an STS movement reflect dynamic knee ...

A Noise-Immune Kalman Filter and Modelling forPedestrian Traffic Loads

open access: yesShock and Vibration, 2020
The definition of design load with walking crowd excitation on these slender structures is a significant problem to human-induced vibration. To capture the characteristics of walking crowd loads, this article researches both the ground reaction force and

Relationship between angle and peak vertical ground reaction force estimation in parachute landing fall among army parachutists using mathematical modelling

open access: yesAlexandria Engineering Journal, 2022
This paper discussed the relationship between angle and the value PvGRF for the execution of parachute landing. The value of PvGRF has been determined by using mathematical modelling principle of conservation of energy.

Acute effects of endurance exercise on jumping and kicking performance in top-class young soccer players [PDF]

open access: yes, 2011
The aim of this study was to examine the acute effects of endurance exercise on jumping and kicking performance in young soccer players. Twenty-one top-class young soccer players (16.1±0.2 years) performed a countermovement jump test and a maximal instep
