The Myth Of Long-Acting Carbohydrates

The Myth Of Long-Acting Carbohydrates
One of the more persistent myths in sports nutrition is the idea that long-acting carbohydrates offer an endurance advantage. This myth is perpetuated by the manufacturers of sports drinks and recovery drinks containing long-acting carbs, who trot out data showing that long-acting carbs provide a more sustained level of blood glucose than fast-acting carbs. Most educated consumers equate steady blood glucose with sustained energy. Manufacturers rely on this association to suggest that, by providing sustained levels of blood glucose, their products containing long-acting carbs also delay fatigue better than products using fast-acting carbs. In fact, just the opposite is true. Here’s why.

New Tool To Calculate Your Fluid And Nutrition Workout Needs
The question I get most frequently from athletes is about how much fluid and nutrition should be consumed during workouts and races.

Insulin And Lean Body Mass
A general misconception is that insulin is only involved in energy and fat metabolism.  When energy needs are high, insulin transports sugar from the blood into the muscle where it can be converted into energy.  When energy needs are low, insulin facilitates the conversion of excess sugar into fat where it can be stored for future use.

Numerous studies have shown that the incidence of depression is higher in the elderly.  It has been suggested that this pattern is associated with serotonin, a brain chemical that influences mood and behavior.  Normal aging is associated with a decline in serotonin levels.  At the same time, there have been many documented studies showing that people who exercise experience less depression.  These studies suggest that exercise provides a protective effect against the development of depression in older individuals.

HOW ACCELERADE SPORTS DRINK CAN PREVENT A SUPER BOWL HANGOVER

For many of us, hangovers that last a few hours and magically disappear like they did in college are no longer a reality.

Bonk-Proof Fueling
Every endurance athlete has "bonked," or "hit the wall" at some point. 30 years ago, scientists believed that extreme fatigue, or bonking, was a result of lactic acid build up. However, research has shown that the causes of fatigue are more complex. There is general agreement that fatigue has two components: a muscle component and a brain component. The question is whether they act in concert or independently.
