Most people who have ears know that music can help us relax, but wait, that’s just beginning. Music can tune up our cardio system, literally. It can also tune it down. The Scientific American reports that researchers at the University of Pavia in Italy have found that changes in the cardiovascular and respiratory systems mirror musical tempo. The journal reports that the scientists enlisted 24 volunteers—half experienced singers, the remainder with no musical training, and had them listen to five random selections of Beethoven,
Bach, Puccini and other classical artists as well as a two-minute
segment of silence, mMusical_Notes_backgroundonitors recorded physiological signals. The
researchers found that selections with crescendos, especially those
with a series of them (think: Queen’s Bohemian Rhapsody),
led to proportional constriction of blood vessels and increases in
blood pressure, heart rate and respiration. These measures decreased
during decrescendos and silent periods. The team also found that “rich”
music phrases around 10 seconds long, like those rhythms from famous
arias by Verdi, caused heart rate and other parts of the cardiovascular
system to synchronize with the music. Sciam reports that both the musicians and non-musicians experienced this
entrainment, although the musicians showed a stronger response.

Now comes a study from researchers at Massachusetts General Hospital and the Broad Institute suggesting that people with genes that boost HDL levels  do not, in fact, have a lower risk of heart attacks. Strange. The Boston Globe reports that the scientists in looked at a gene variation that raises HDL levels, and should consequently give people a 13 percent decreased [...]

    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 [...]

    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 [...]
