Carbohydrates and Running Performance

Description

Carbohydrates serve as the body's primary energy source during intense exercise, and consuming carbohydrates during exercise has been shown to improve exercise performance. Previous research has shown that the presence of carbohydrates in the mouth activates sweet taste receptors on the tongue, which signal the brain to increase neural activation in areas associated with motor functioning, sensory perception, and reward centers during exercise through this CPR. The primary objective of this intervention is to establish how carbohydrates delivered in different forms (MR versus dissolvable strip (DS)) affect running performance during a 12.8km running TT.
