How does sugar affect physical activity?

sugarSugar is known for its bad reputation. It is blamed for the development of obesity, diabetes and many other diseases. But how does sugar affect the human body in motion? Is there a difference in the effects of sugar on active and lazy people? “How Sugar Affects the Body in Motion”, published in the New York Times online release.

Several recent studies suggest that individuals who exercise regularly do not have to worry because of excessive consumption of fructose and other sugars. In some circumstances, the consumption of sugars is even beneficial for them.

The unique effect of various sugars on physical exertion has been well illustrated by the latest research published in Medicine & Science in Sports & Exercise. The study was subjected to a group of well-trained cyclists. The experience was attended by men only. They had to ride their bike until the forces were exhausted in a few different situations. After each ride they drank a drink of fructose, glucose or other simple sugar.

The liver is the body that we ignore in the consideration of physical activity. However, it plays an important role during physical exertion. It stores glycogen, which is an inventory of glucose for the organism. All sugars are converted into glucose and stored in the form of glycogen in the body. Extensive exercise causes the loss of glycogen in the liver, and until they are rebuilt the body is not fully prepared for subsequent exercises.

In the study, scientists used magnetic resonance imaging to measure the liver size of each cyclist before and after the ride. All cyclists decreased the liver volume after exertion, which means decreasing glycogen stores. Those cyclists who later drank fructose quickly regained glycogen stores. However, those cyclists who drank the drink sweetened with glucose, were much slower at recovering the glycogen store. The researchers found that sweetened fructose drinks are twice as efficient as sugar-sweetened beverages.

Interestingly, the uptake of sugars is best when the beverage contains both glucose and fructose. Carried out in 2008 years, the study showed that cyclists who were drinking a glucose-sweetened drink during a biannual ride at moderate speeds than those who drank only water. However, those cyclists who drank a drink sweetened with glucose and fructose in their time trial were receiving 8 percent better results.

However, do not immediately reach for sugar. It turns out that sweetened preparations for athletes are intended only for people who train for more than two hours. If your workout is limited to 30 minutes a day, you don’t need an extra carbohydrate.

However, these studies suggest that even if your walk takes only 30 minutes it affects your blood sugar level. According to Dr. Richard J. Johnson’s activity may reduce the risks associated with eating fructose and other sugars.

In individuals who lead a sedentary lifestyle, consuming large amounts of fructose may lead to fatty liver disease. This affects the body’s ability to react to insulin, a hormone that controls blood glucose levels. Already a small amount of regularly performed exercises can stop this process and lead to a decrease in liver fat.
