In this study, alterations of heel strike angle (HSA) and plantarflexion velocity (PFV) in the sagittal plane due to wearing different shoe conditions was examined. By this, adaptation in running style as a mechanism of shock attenuation should be investigated. Methods Twenty-four male, injury-free recreational runners (age: 24.8 ± 2.5 years, height: 177.7 ± 5.8 cm, weight: 73.1 ± 7.1 kg) parti...

The advent of the “Running Boom” in the late 1970’s coincided with the introduction of the first “technical” running shoe products incorporating cushioned soles and features intended to stabilize the foot during ground contact. The sensation of comfort provided by cushioned running shoes appears to have facilitated the participation of many “joggers” who would otherwise not have taken up the sp...

In this paper we investigate the use of an innovative sheet folding theory and technology in the design of new cushioning systems. Flat sheets of material are folded into three dimensional patterns. The effectiveness of the folded pattern in absorbing impact energy without subjecting items being cushioned to high acceleration is dependent on the sheet material, the fold configuration (number of...

At present, the packing method of “plastic bag–buffer packing–packing paper box” is adopted for bearing packaging. However, common has a poor effect and versatility. In this study, new biomimetic cobweb cushion proposed to solve problem insufficient cushioning capacity high-precision packaging pads. First, according nature form, structure configuration determined. Next, based on relationship be...

In this presentation, methods to analyze biomechanical data of runners to facilitate classification of the prevailing running surface situation are discussed. We are considering an embedded application example from the field of digital sports: A novel running shoe capable of acquiring parameters specific to the run and setting its cushioning accordingly. The developed classifier is used in the ...

Background The cushioning of running shoes and leg stiffness influence tibial impact shock [1]. This knowledge, however, is based on investigations with the same cushioning at both feet. Unknown is whether leg stiffness can be adjusted for each leg individually. Thus, the purpose of this study was to quantify effects of differently cushioned running shoes at the left and right foot on running s...

OBJECTIVE This investigation aims to determine if more expensive running shoes provide better cushioning of plantar pressure and are more comfortable than low-cost alternatives from the same brand. METHODS Three pairs of running shoes were purchased from three different manufacturers at three different price ranges: low (40-45 pounds), medium (60-65 pounds) and high (70-75 pounds). Plantar pr...

Foot-ground interfaces exist in many different forms. Frequently the interface is a shoe or floor mat, and sometimes it is a carpet-like material, such as an Astroturf, providing specific biomechanical characteristics to help one perform effectively. Hence these interfaces can play an important role in improving functionality or performance, preventing injury, and reducing discomfort. Human mov...

Background Court shoe designs predominantly focus on reducing excessive vertical ground reaction force, but shear force cushioning has received little attention in the basketball population. We aimed to examine the effect of a novel shoe-cushioning design on both resultant horizontal ground reaction forces and comfort perception during two basketball-specific cutting movements. Methods Fiftee...
