A Little Known Secret: Help Athletes Achieve Endurance, Agility


Scientists have found that “brain carbohydrate-loading” can make the difference between an ordinary workout session and an extraordinary, sustained workout program. Athletes for example, who perform prolonged rigorous exercises, rapidly become hypoglycemic, depleting circulating blood glucose levels and glycogen stores in the muscles and brain; these changes are  linked to early fatigue. If an athlete were to simply load up on a small, healthy dose of carbs, in between workouts they would perform at a higher cognitive level, achieving longer endurance, and agility.

In part 1 of a new experiment, published last year in The Journal of Physiology,scientists revealed just how counter-productive depleted brain glycogen stores are to persons who engage in strenuous exercises for a living. Problems such as muscle injury, early fatigue, and reduced cognitive functions are detrimental terms to athletes.

Brain glycogen, the storage form of glucose that feeds neurons in the brain during exhaustive exercises, is a critical energy source for sports competitors “when the glucose supply from the blood is inadequate.”

By “using [their] clever glycogen detection methods, they [scientists] discovered that prolonged exercise significantly lowered the brain’s stores of energy, and that the losses were especially noticeable  in certain areas of the brain, like the frontal cortex and the hippocampus, that are involved in thinking and memory, as well as in the mechanics of moving.”

The good news is that part 2 follow-up experiment, showed that after a bout of exhaustive exercise, rest, then feeding, brain levels of glycogen in lab mice, surpassed its normal storage level by as much as 60 percent. This “overcompensation” resulted in a kind of brain carbo-loading, specific to areas of the brain responsible for higher learning and movement. The study appears in this month’s issue of The Journal of Physiology.

The spike in brain glycogen lasted 24 hours, and then returned to normal. But, in a fascinating twist in results, when consistent high intensity workout is maintained over time, the brain “super-compensated” becoming a super storage site as the new norm over baseline levels of glycogen. Again, these brain carbo-loading occurred in-between sessions of intense workout, in areas known as the “seats of higher learning,” which is the cortex, in addition to the hippocampus, for the development of a better sharper brain.

The implications of these experiments are far reaching. They reveal that a brain, with more fuel reserves, is potentially a higher functioning brain that can sustain and direct movements longer.  It opens up a whole new realm in sports where contenders can fuel their own super-compensating brain in between competitions by having a wholesome form of glucose (not sugary sports drink) such as chocolate milk, bananas, or fruit shakes to rev up their performance.

A highly functioning brain is one that is capable of achieving phenomenal feats. Athletes can achieve these feats through brain carbo-loading, a scientific term that refers to creating fuel reserves in the brain in between exercises, for peak performance.

Heart Attack Symptoms in Women—Undefined?


Article first published as Heart Attack Symptoms in Women—Undefined? on Technorati.

Women’s biological issues have become the forefront of several heated political debates on the campaign trail, now news of women’s vulnerability to death from misdiagnosed symptoms of heart attack, posit medical neglect along gender lines. According to recently published studies in the Journal of the American Medical Association (JAMA) “women are less likely to be properly treated, even when they have similar symptoms to men.”

Heart attack has been known for decades as the number one killer of men in the United States, but more and more studies are showing that this statistical claim may be inaccurate.  Cam Patterson, Chief of Cardiology at the University of North Carolina-Chapel Hill remarked that this research “actually may underestimate the gender gap, because many female heart attacks never make it to the hospital.”

The study, authored by John Canto of the Watson Clinic and Lakeland Regional Medical Center in Florida tracked more than 1.1 million patients. In the study, 15 percent of female heart attacks die in the hospital compared with 10 percent of men, due mainly to misdiagnosis and inaction to stop heart attacks.

Should doctors be liable for women’s neglect at health care facilities or should their training and medical guidelines take center focus? The same study shows that 42% of women never experience the classic heart attack symptoms, particularly, those women who are younger or premenopausal, compared with 31% of men.

Although numerous campaigns launched over the years have tried to educate women about the symptoms, both women and their doctors have failed to recognize them or the need to seek immediate medical attention.

The classic heart attack symptoms for women under 55 years, according to the American Heart Association are:
Number 1: Shortness of Breath
Number 2: Nausea and vomiting, and gastrointestinal discomfort
Number 3: Light headedness and pain in the back or jaw
Number 4: Crippling fatigue and the sudden need to take a rest

These women face imminent danger from a myocardial infarction (heart attack). Women at risk are: hypertensive, have high cholesterol, are obese, and are diabetics. They should know these numbers and start a health plan:
Number 1: Blood Pressure measure
Number 2: Cholesterol level
Number 3: Blood sugar level
Number 4: Body Mass Index (BMI)

Further, women should speak to their doctors about aspirin control.

Besides knowing what symptoms to expect, a woman should take full control of her own health, limiting the incidence of an undefined medical diagnosis as much as possible
