Running economy is expressed as oxygen uptake (VO2) or energy cost relative to body weight when running at submaximal velocities. Theoretically the loss of bodyweight (2-3% bodyweight) associated with sweating and dehydration should reduce the VO2 cost of running. To avoid the confounding factors associated with dehydration (e.g., increase in core temperature), we investigated the sensitivity of the VO2 cost of running with added weight inserted in a “weight jacket” worn around the torso of the body. Running economy was tested in thermoneutral conditions with subjects in a euhydrated state.

Abstract
Running economy is expressed as oxygen uptake (VO2) or energy cost relative to body weight when running at submaximal velocities. Theoretically the loss of bodyweight (2-3% bodyweight) associated with sweating and dehydration should reduce the VO2 cost of running. To avoid the confounding factors associated with dehydration (e.g., increase in core temperature), we investigated the sensitivity of the VO2 cost of running with added weight inserted in a “weight jacket” worn around the torso of the body. Running economy was tested in thermoneutral conditions with subjects in a euhydrated state.File in questo prodotto:
