Decreased Physical Performance During Energy Deficit Independent of Consuming Glucose or Glucose + Fructose

Objectives: Suboptimal carbohydrate and energy intake can contribute to declines in physical performance in military and athlete populations. Whether acute carbohydrate supplementation aids in maintaining physical performance during energy deficit compared with energy balance is unclear. Furthermore, whether the source of carbohydrate impacts physical performance during energy deficit is undetermined. The objective of this study was to examine the effects of consuming glucose (GLU) or glucose + fructose (GLU + FRU) under energy balance (BAL) or deficit (DEF) on physical performance.
