Ground reaction forces during downhill and uphill running.
We investigated the normal and parallel ground reaction forces during downhill and uphill running. Our rationale was that these force data would aid in the understanding of hill running injuries and energetics. Based on a simple spring-mass model, we hypothesized that the normal force peaks, both impact and active, would increase during downhill running and decrease during uphill running. We an...
متن کاملUphill/downhill nystagmus
Differential diagnosis between peripheral and central spontaneous nystagmus can be difficult to classify (as peripheral or central) even on the basis of criteria recommended in the recent literature. The aim of this paper is to use the combination of spontaneous nystagmus and ocular tilt reaction to determine the site of origin of the disease that causes nystagmus. We propose to classify the ny...
متن کاملUphill or Downhill
Companies know the amount of profit they make, but may not know whether they are operating on the uphill side or downhill side of the profit function with respect to each marketing investment variable. We first identify the risks of an uphill-located firm acting as if it were a downhill-located firm. Then, we develop a diagnostic tool to infer a company’s type based on its location on the profi...
متن کاملEffect of Level and Downhill Running on Breathing Efficiency
Ventilatory equivalents for oxygen and carbon dioxide are physiological measures of breathing efficiency, and are known to be affected by the intensity and mode of exercise. We examined the effect of level running (gradient 0%) and muscle-damaging downhill running (−12%), matched for oxygen uptake, on the ventilatory equivalents for oxygen (V̇E/V̇Ο2) and carbon dioxide (V̇E/V̇CO2). Nine men (27 ± 9...
متن کاملThe role of elastic energy storage and recovery in downhill and uphill running.
In level running, humans and other animals store and recover elastic energy during each step. What role does elastic energy play during downhill and uphill running? We measured the fluctuations of the mechanical energy of the center of mass (CoM) of 15 human participants running at 3 m s(-1) on the level, downhill and uphill on a force-measuring treadmill mounted at 3, 6 and 9 deg. In level run...
