Reliability of ground reaction forces in the aquatic environment [PDF]

Journal of Electromyography and Kinesiology, 2016
The aim of this study was to verify the reliability of the kinetic parameters of gait using an underwater force platform. A total of 49 healthy participants with a median age of 21years were included. The kinetic gait data were collected using a 0.6×0.6×0.1m aquatic force plate (Bertec®), set in a pool (15×13×1.30m) with a water depth of 1.20m and ...

Bilateral Ground Reaction Force Asymmetry During Supramaximal Drop Landings

International Journal of Strength and Conditioning, 2022
Bilateral vertical ground reaction forces (vGRF) asymmetries have not been investigated during supramaximal drop heights. The first purpose of this study was to investigate the influence of drop height on impact and attenuation vGRF impulses.

The Effect of Foot Orthosis on the Vertical Component of the Ground Reaction Force While Walking: A Review Study

Journal of Rehabilitation, 2021
Objective Everyone is required to walk and stand for long time in daily activities, especially in the workplace. As a result, the Ground Reaction Force (GRF) on the components and joints is so great that they sometimes reach several times the weight of ...

Ground reaction force estimates from ActiGraph GT3X+ hip accelerations. [PDF]

PLoS ONE, 2014
Simple methods to quantify ground reaction forces (GRFs) outside a laboratory setting are needed to understand daily loading sustained by the body. Here, we present methods to estimate peak vertical GRF (pGRFvert) and peak braking GRF (pGRFbrake) in ...

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.
