Objective.The aim of this study was to investigate the effects of surface stiffness on multisegment foot kinematics and temporal parameters during running.Methods.Eighteen male subjects ran on three different surfaces (i.e., concrete, artificial grass, and rubber) in both heeled running shoes (HS) and minimal running shoes (MS).Both these shoes had
There are two basic aspects of attentional control.The ability to direct attention toward different objects is typically experienced as a fundamental indicator of attentional freedom.One can control what one attends to and directing attention is a relatively simple task.In contrast, sustaining attention on a chosen object proves to be difficult Sup
The risk premium and the probability premium are used to determine appropriate coefficients of absolute risk aversion under CARA utility.A Supplies defensible range of risk aversion coefficients is defined by the coefficients that correspond to risk premiums falling between 1 and 99% of the amount at risk or to probability premiums falling between.
