milk might be better for athletes energy drinks

Scientists say they have growing evidence that some athletes say, that the milk could be as good or even better than some energy drinks to recover after exercise.

milk benefits for health are known for some time. The fluid contains carbohydrates, electrolytes, calcium and vitamin D, but also has the two most recommended protein to rebuild muscles: casein and whey.


muscles after suffering intense aerobic session, such as running, playing soccer or riding bikes and the casein and whey proteins are precisely what the body needs to regenerarar muscles quickly.


At the end of almost all physical training sessions, Matt Whitmore takes a pint of milk from the bottle. "I do quite religious" Whitmore said, a coach of 25 years who lives in London.


The coach started to take milk after exercise 10 years ago when I could not pay for supplements, protein drinks or more expensive. "Milk helps me recover faster and I feel great afterwards," he said. "Now, I like to go without taking it."


Glenys Jones, a nutritionist at the Medical Council of Britain, said the milk protein content makes it the ideal drink after a workout. "Milk provides the building blocks you need to build new muscles," he said.


The nutritionist reported that sports drinks simply replace carbohydrates and electrolytes lost, but usually do not have the nutrients needed to regenerate the muscles.


experts have not been able to agree to determine if the milk is better than energy drinks.


dairy producers have wanted to enter that market millionaire, in some cases funding studies on the benefits of milk for athletes, but some believe that the investigations are biased. The debate continues, as the milk continues to gain attention.


In a study published in June in the Journal of Applied Psychology Physiology, Nutrition and Metabolism, lols scientists found that people who consume milk after resistance exercise was longer in the next session of exercise than those taking other sports drinks or water.


"is the form of carbohydrates and nutrients of milk are more important," said Emma Cockburn, a professor in sports training at the University of Northumbria University in northeast England, and author of the study, which was funded part by the dairy industry

Doctors warn of danger to the eyes of women

A 15 year old boy was seriously damaged eye while playing with a laser pointer he bought on the internet, doctors said warn that dangerous high-power versions of these devices are available online.

An ophthalmologist described it as "a legitimate threat to public health."

The boy's case is published in Thursday's issue of the journal New England Journal of Medicine by doctors who treated him at the Cantonal Hospital of Lucerne, Switzerland.

The case follows two reports of similar accidents in June. British doctors say a teenager was injured eye with a high power laser pointer, and a British doctor reported vision problems for several months after he was hit by light emitted a pointer used by his 7 years.

Laser pointers are devices that resemble feathers and emit a narrow beam of laser light. They are used at conferences to highlight information during presentations, for example.

pointers sold in the U.S. are subject to a power limit set by the Food and Drug Administration (FDA, for its acronym in English) so as not to cause instant damage to the eyes, although it is possible there is damage if exposure is prolonged.

laser pointers that go beyond the limits of the FDA, however, are available online.

The Swiss child acquired the internet got a laser pointer 30 times more potent than the FDA limit. He bought it to blow up balloons and making holes in paper and sneakers from his sister, doctors said.

One day the child was playing with the pointer in front of a mirror to create a light show, but the green beam accidentally hit his eyes several times.

vision in his left eye was so affected that he could not count the fingers of another person to more than one meter (three feet) away. His other eye also had a severe loss of vision, so serious that it was difficult to read a newspaper, said in an e-mail Dr. Martin Schmid, one of the doctors who brought the case.

Tests showed that the child had a hemorrhage in the left eye and several small scars on the right.

"This is a legitimate threat to public health," said Williams, a spokesman for the American Academy of Ophthalmology. "Parents should be aware that lasers are inadequate and available through the Internet," he said.
