One remarkable thing about the anti-oxidant quercetin: it has an amazing ability to boost endurance. Wait: Four more things you should know: it is found in the skins of red apples, red onions, berries and grapes.
Medical News Today reports20080926apples on research conducted at the University of South Carolina’s Arnold School of Public Health, suggesting that the antioxidant significantly boosts endurance capacity and maximal oxygen capacity
(VO2max) in healthy, active but untrained men and women. The online journal reports that 12 study participants were randomly assigned to one of two treatments. Half
were given 500 milligrams of quercetin twice a day in Tang for seven
days. The other subjects drank Tang with placebos. After the seven days
of treatment, during which the subjects were told not to alter their
physical activity, the participants rode stationary bicycles to the
point of fatigue. At that point, researchers tested their additional VO2max, one of the most
important measures of fitness. The study participants then received the
opposite treatment for another seven days before riding the bicycle to
the point of fatigue and more VO2max tests. Neither the participants nor the
research staff knew who received the quercetin Tang or the placebo
Tang, and all subjects took part in the quercetin and placebo
treatments. The researchers, MedicalNewsToday reports, found that after taking quercetin for only seven days, the
participants had a 13.2 percent increase in endurance and a 3.9 percent
increase in VO2max.

    So if the Q is not followed by a “u”, then why do you spell it that way below in your article, and why does everyone else also spell it as “quercetin.”
    On a separate note, does this stuff have any effect on athletes, or only on slobs?

    Sports That Don’t Break Your Bones Make Them Stronger

    What doesn’t break your bones makes them stronger. Especially if what doesn’t break your bones is a load-bearing sport like basketball or volleyball. How to we know? Because when researchers at the University of Gothenburg in Sweden measured the bone mass of more than 800 young men and studied their exercise habits, they found that after five years, the men who did a lot of load-bearing activities at the start of the study and those who increased their amounts of [...]

    Camel Jumping Strengthens Core

    Sports physiologists have yet to analyze the muscle groups that benefit most from the popular Yemenite entertainment plainly named “camel jumping,” but we’re guessing it’s good for the core, and not so good for the ankles. The New York Times’ Lens gives us an enlightening photo essay, shot, admittedly, by a photographer in Yemen who got bored waiting around for actual news. Anyone up for an over-50 team?

    Email Dependence Is Bad For Your Health

    Don’t have time to read SportsGeezer because you just got an email? That’s a bad sign, according to researchers at the University of California at Irvine. Researchers at the school attached heart rate sensors to workers in a suburban office, and divided the users into two groups; one with email, one deprived. A university news release reports that people who read email were found to work in a steady “high alert” state, with more constant heart rates. Those removed from [...]

    “Workout Boosters” Boost Blood Pressure Too

    The names of the products—Jacked3D, Oxy Elite Pro, Code Red, and Nitric Blast, should offer some clues to the kind of science behind their sales; the science of marketing. Now comes the science of medicine, brought to bear on these “workout boosters” by the Food and Drug Administration, which determined that the active ingredient in the supplements, dimethylamylamine or DMAA, said in marketing materials to increase energy, concentration and metabolism, actually increases blood pressure. The FDA has sent letters to [...]

    Latest Treatment For Chronic Pain: Don’t Think About It

    Researchers in the psychiatry and behavioral science department of Johns Hopkins Medical School have some radical advice for sufferers of chronic pain: don’t think about it.

    For Heart Health, Coffee Not Soda

    Why is is unsurprising that soda has been associated with a higher risk of stroke? Perhaps because it has long been associated with weight gain, diabetes, high blood pressure, high cholesterol, and coronary artery disease. Hmmm. Now, finally, comes a study from the Cleveland Clinic’s Wellness Institute and Harvard University, showing not only that sugar-sweetened and low-calorie sodas is associated with a higher risk of stroke, but that coffee, either caffeinated or decaffeinated, is associated with a lower risk. A [...]
