Exercise energetics in normal man following acute weight gain

Abstract
To test the recently suggested hypothesis that acute weight gain reduces the efficiency of muscular work, four normal subjects performed an incremental work test on a cycle ergometer before and after weight gain. Work efficiency, computed from steady-state gas exchange measurements, was unaffected by the weight gain. These findings, coupled with computational inconsistencies in the work which suggested this mechanism, cause us to reject the hypothesis that work efficiency is reduced in normal subjects by acute weight gain.
