This paper describes a two-part study evaluating the use of growth hormone (GH) response to infusions of somatostatin (SRIF) and GH-releasing factor (GRF) as an indicator of genetic merit in dairy cattle. The first part of the study involved the development of a standard test procedure. This was achieved in two sub-trials, the first testing three SRIF doses, 0·6, 3·0 and 15 μg/kg per h, given o...

Force platforms are used extensively to measure force and power output during countermovement jump (CMJ). The purpose of this study was to examine measurement reliability and validity of commonly used performance measurements derived from ground reaction force (GRF)-time data during CMJ and the influence of sampling at different frequencies. Twenty-four men performed 2 trials of CMJ on a force ...

In this paper, we present a new method to estimate ground reaction forces (GRF) from wearable sensors for variety of real-world situations. We address the drawbacks using force plates with limited activity range and high cost in previous work. use transformer encoder as feature extractor extract temporal spatial features more efficiently. Using Mean Absolute Percentage Error (MAPE) evaluation c...

This study proposes a force plate with planar spring and an eddy current displacement sensor to measure the ground reaction (GRF) of small insect reveal its motion characteristics. The proposed comprises circular aluminum plate, four springs symmetrically connected under plate. diameter thickness fabricated were 8 0.1 mm, respectively. width was 0.4 mm. When is applied moves vertically downward...

Improved lower extremity neuromuscular control during sports may decrease injury risk. This prospective study evaluated progressive resistance, whole body, long-axis rotational training on the Ground Force 360 device. Our hypothesis was that device training would improve lower extremity neuromuscular control based on previous reports of kinematic, ground reaction force (GRF) or electromyographi...

Mechanical load has been estimated during step exercise based on ground reaction force (GRF) obtained by force platforms. It is not yet accurately known whether these measures reflect foot contact forces once the latter depend on footwear and are potentially modified by the compliant properties of the step bench. The aim of the study was to compare maximal and mean plantar pressure (PP), and ma...

Over the years, Global Reporting Format (GRF) was first major change in approach to evaluate runway conditions. The greatest impulse for this new regulation were incidents and accidents related mainly excursions that occurred because of unfavorable weather conditions, when not only aircraft different airport facilities but also human health lives suffered. To better understand these changes, th...

BACKGROUND Knee valgus and varus morbidity is at the second top place in children lower limb deformity diseases. It may cause abnormal stress distribution. The magnitude and location of contact forces on tibia plateau during gait cycle have been indicated as markers for risk of osteoarthritis. So far, few studies reported the contact stress and force distribution on tibial plateau of valgus kne...
