BACKGROUND Sidestep cutting technique is essential in programmes to prevent anterior cruciate ligament (ACL) injury. A better understanding of how technique affects potentially harmful joint loading may improve prevention programmes. The purpose of this study was to investigate the effect of sidestep cutting technique on maximum knee abduction moments. METHODS Cross-sectional study. Whole-bod...

This article describes a public data set containing the three-dimensional kinematics of the whole human body and the ground reaction forces (with a dual force platform setup) of subjects who were standing still for 60 s in different conditions, in which the subjects' vision and the standing surface were manipulated. Twenty-seven young subjects and 22 old subjects were evaluated. The data set co...

The in vivo growth hormone (GH) response of immature domestic fowl to thyrotrophin-releasing hormone (TRH) and GH-releasing factor (GRF) was suppressed in birds fed diets supplemented (1 ppm) with triiodothyronine (T3) or given bolus intraperitoneal (ip) injections (100 micrograms/kg for 10 d) of T3. Supplementation (ppm) of the diet with T4 had no effect on secretagogue- induced GH release. Ex...

This study aimed to use the plantar pressure insole for estimating the three-dimensional ground reaction force (GRF) as well as the frictional torque (T(F)) during walking. Eleven subjects, six healthy and five patients with ankle disease participated in the study while wearing pressure insoles during several walking trials on a force-plate. The plantar pressure distribution was analyzed and 10...

To better understand the pathophysiology and functional outcomes of musculoskeletal neuromotor pathologies, research is often conducted in mice models. As a key component such research, metrics movement, loading, symmetry, stability all have to be assessed, ideally requiring measurement 3D ground reaction forces, which can difficult. While forces (GRF) well developed for humans, appropriate dev...

Greenlandic fjords contain vast amounts of glacially derived mineral material (glacial rock flour, GRF), which may be used to amend structureless, low-clay, and/or water-repellent agricultural soils in South Greenland and elsewhere. In this study, we investigate key physical amendment properties GRF from 16 different deposits Greenland. The clay-sized fraction varied largely (range: 0.11 – 0.57...

BACKGROUND Locomotion results from the generation of ground reaction forces (GRF) that cause translations of the center of mass (COM) and generate moments that rotate the body around the COM. The trot is a diagonally-synchronized gait performed by horses at intermediate locomotor speeds. Passage is a variant of the trot performed by highly-trained dressage horses. It is distinguished from trot ...

Research suggests that heightened impacts, altered joint movement patterns, and changes in friction coefficient from the use of artificial surfaces in sport increase the prevalence of overuse injuries. The purposes of this study were to (a) develop procedures to assess a tennis-specific movement, (b) characterize the ground reaction force (GRF) impact phases of the movement, and (c) assess huma...

It is common practice to study jump landing mechanics by having subjects step off a box set at a certain height instead of landing from a jump. This practice assumes that the landing mechanics are similar between stepping off a box and a countermovement jump as long as the heights can be matched. The mechanics of the two methods had never been compared when landing from identical heights. Thus,...
