New research shows carbohydrate rinse may be as effective as consumption. They theorized that if that’s the case, carbohydrates should have little to no effect on shorter races since the body doesn’t metabolize glycogen that quickly. So HK author, Asker Jeukendrup, and his colleagues began to question why—and what they found was remarkable: just rinsing the mouth with a carbohydrate solution had the same effect as drinking it.
Convincing evidence from numerous studies indicates that carbohydrate feeding during exercise of about 45 minutes or longer (Jeukendrup 2004, 2008; Jeukendrup et al. A drop in carbohydrate oxidation occurred after about 1.5 hours of exercise with placebo, and high rates of carbohydrate oxidation were maintained with carbohydrate feeding. Several factors have been suggested to influence exogenous carbohydrate oxidation including feeding schedule, type and amount of carbohydrate ingested, and...

Exercise performance is impaired when an individual is dehydrated by as little as 2% of body weight. The endurance capacity during incremental exercise is decreased by marginal dehydration (fluid loss of 1% to 2% of body weight), even if water deficits do not actually result in a decrease in . Dehydration also appeared to reduce the core temperature a person could tolerate, as core temperature at exhaustion was about 0.4° C (0.7° F) lower in the dehydrated state.
Amenorrheic female athletes should certainly take calcium supplements, and other female athletes should consider taking calcium supplements, to ensure adequate calcium status and maintain healthy bones. Although vitamin and mineral supplementation may improve the nutritional status of athletes consuming marginal amounts of micronutrients from food and may improve performance in athletes with deficiencies, there is no convincing evidence to indicate that doses in excess of the RDA improve ...
