2 ABSTRACT The overuse injuries commonly experienced by runners can be attributed to a number of risk factors. The primary risk factor is repetitive impact loading of the lower extremity, but anatomical predispositions, excessive subtalar joint pronation, running surfaces, shoes and training habits all contribute to the probability of injury. Running shoes are rarely the sole cause of an injury...

This study aims to develop a numerical method that can be used to investigate the cushioning properties of different insole materials on a subject-specific basis. Diabetic footwear and orthotic insoles play an important role for the reduction of plantar pressure in people with diabetes (type-2). Despite that, little information exists about their optimum cushioning properties. A new in-vivo mea...

Strong health and economic policies allowed for quick recovery from initial COVID-19-related lockdowns in 2020. Renewed outbreaks have created setbacks since mid-2021, with disproportionate impacts on some regions, sectors, workers. Accommodative macroeconomic been instrumental cushioning the impact.

Abstract The diagram of thread guide with composite rollers in a sewing machine is given the article. Based on solving problem oscillations outer bush compound roller guide, dependence changes amplitude deformation values cushioning has been obtained. Values stiffness coefficient have substantiated.

To reduce maintenance costs, municipalities and schools are starting to replace natural grass fields with a new generation synthetic turf. Unlike Astro-Turf, which was first introduced in the 1960s, synthetic field turf provides more cushioning to athletes. Part of this cushioning comes from materials like crumb rubber infill, which is manufactured from recycled tires and may contain a variety ...

The vibration environment is a common man-made artificial surrounding with which humans have a limited tolerance to cope due to their body dynamics. This research studied the dynamic characteristics of a seated human body/seat system in a vibration environment. The main result is a multi degrees of freedom lumped parameter model that synthesizes two basic dynamics: (i) global human dynamics, th...

In the material handling business original equipment manufacturers, lift truck dealers and distributors find themselves marketing polyurethane and rubber tires simultaneously. To achieve optimum performance one needs to better understand the attributes of each product. In this article, both products will be broadly compared along with their proper application, with an emphasis on polyurethane t...
