Ground reaction force metrics are not strongly correlated with tibial bone load when running across speeds and slopes: Implications for science, sport and wearable tech

PLoS ONE, 2019
Introduction Tibial stress fractures are a common overuse injury resulting from the accumulation of bone microdamage due to repeated loading. Researchers and wearable device developers have sought to understand or predict stress fracture risks, and other

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

, 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

BMC 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

Frontiers 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.

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

, 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 (

A Noise-Immune Kalman Filter and Modelling forPedestrian Traffic Loads

Shock 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

Alexandria 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]

, 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

Developing a Low-Cost Force Treadmill via Dynamic Modeling [PDF]

, 2017
By incorporating force transducers into treadmills, force platform-instrumented treadmills (commonly called force treadmills) can collect large amounts of gait data and enable the ground reaction force (GRF) to be calculated.
