Carbohydrates and Physical/Mental Performance during Intermittent Exercise to Fatigue

Investigated the effects of carbohydrate-electrolyte (CHO) ingestion on physical and mental function associated with performing high-intensity exercise. Physically active adults completed physical activities while researchers assessed them. CHO or placebo drinks were consumed before starting and at...

Description
Summary:Investigated the effects of carbohydrate-electrolyte (CHO) ingestion on physical and mental function associated with performing high-intensity exercise. Physically active adults completed physical activities while researchers assessed them. CHO or placebo drinks were consumed before starting and at halftime. CHO ingestion resulted in 37 percent longer run time to fatigue and faster sprint times, and it heightened mental function. (SM)
