Building Strong Bones Through Impact

March 7, 2014 12:57 pm 1 comment

imagesMany people of a certain age avoid high-impact exercise, fearing that the jolts of running and jumping might be hard on aging joints and bones. They may be right, but for those whose bodies can take the hits, high impact exercise may be just what the researchers ordered. Writing in the New York Times, Gretchen Reynolds reports on a recent study that found that “women between 25 and 50 who hopped at least 10 times twice a day, with 30 seconds between each hop, significantly increased their hipbone density after four months.” Reynolds says another group of subjects, who hopped 20 times daily, showed even greater gains. Researchers had already known, according to Reynolds, that high-impact exercise made the bones of adolescents stronger. The dilemma, of course, is determining the risks and rewards of high-impact exercise on aging athletes, whose bones may truly be too brittle to withstand the pounding of running or jumping. The answer, says one expert quoted by Reynolds, is caution. If you’re worried about it, consult a doctor before getting on the basketball court. Read more in the New York Times.

  • Running and jumping can be very dangerous for the joints, but this is especially true for overweight and aged (not aging) people. Sure, even in those two cases, it can help with bone density if it’s accompanied by a proper diet (lots of calcium and vitamin D – sunshine) but as far as the level and intensity of activity is concerned – moderation really is the key.
    Thank you for sharing the NYT article. I’ll make sure to pass this information to my elders.

    Heavy Drinker Or Alcoholic? That Is The Question

    Is this good news? The New York Times reports that a new study of results from the National Survey on Drug Use and Health suggests that nine out of 10 people who drink too much are not addicts, and can change their behavior with sufficient prompting. It could be good news, except the Times also reports that excessive drinking, the kind practiced by non-alcoholics as well as alcoholics, results in 88,000 deaths a year, from causes that include alcohol poisoning and […]

    Walnuts Slow Prostate Cancer

    Yes, it appears to be true: walnuts slow the growth of prostate cancer, at least in mice. A UC Davis news release reports that researchers at the school had found, in a previous study, that walnuts reduced prostate tumor size in mice, but the researchers weren’t sure which parts of the nuts generated these benefits. This time around, the researchers used a mixture of fats with virtually the same fatty acid content as walnuts as their control diet. Mice were […]

    Ski Season Is Just Around The Corner. Are You Ready?

    It’s true that many midwesterners are less than thrilled with this week’s blast of winter weather, but skiers elsewhere are getting psyched. But wait, there’s something else: getting in shape. A quick review of the forest of websites offering get-into-ski-shape advice reveals general agreement on the benefits of two exercises: squats and lunges. The rest, my friends, is chatter. Livestrong.com describes squats as “the cornerstone” of your skiing workout,” and recommends that you compound the gain (and pain) by doing […]

    Why Scratching An Itch Makes It Worse

    No, it doesn’t make sense. Why would scratching an itch make it itch even more? It’s like eating food making you more hungry. Researchers at Washington University in St. Louis thought so too, so they did some scratching experiments–with mice, of course, not humans, to find out why. Why? It’s about itch signals and pain signals and brain chemicals jumping tracks.  A Wash U news story reports that the researchers found that scratching creates a mild amount of pain in the skin, which […]

    Another Bad Way To Treat Low-Grade Prostate Cancer

    It’s called androgen deprivation therapy, ADT for short, and it works like this: drugs (and there are several that can be used) are administered, often by injection, to suppress testosterone production, because lowering testosterone levels has been shown slow the growth of prostate cancer cells. But wait. Now, from researchers at Tulane University, comes a study showing that for men with low-grade, slow-growing disease, ADT can do more harm than good. There are two reasons for that: one, low-grade prostate […]

    There are some very pleasant ways to keep the weight off–playing tennis or swimming–and then there are two much less pleasant conditions that researchers at Yale believe could do the same thing, by turning white fat (bad) into brown fat (good.) Cold and hunger. Yes, staying cold and hungry could keep us thin. Maybe.  Yale News reports that researchers at the Yale School of Medicine have uncovered a molecular process in the brain known to control eating that transforms white fat into brown […]

    Brain games, the computer based mental challenges that promise to boost the brain power of older adults, are an excellent way to waste time, but they do almost nothing to make us smarter. That’s the opinion of 69 scholars, including many cognitive psychologists and neuroscientists from around the world. A Stanford University news release reports that the scholars, who have jointly issued a statement expressing their skepticism, say that while people who play computer brain games may improve their scores on […]
