In this video, Gretchen Reynolds, the New York Times Phys Ed columnist, talks with Stuart Phillips of McMaster University about the gains in store for those who train with weights, even light weights. Also, Phillips reveals his idea of the single best exercise.
Is the benefit of cooling down just another exercise myth? The short answer, according to Gretchen Reynolds, of the New York Times, is “yes”. Reynolds points us to a recent study of 36 active adults, who did a strenuous, one-time program of forward lunges while holding barbells, an exercise, Reynolds says, “almost guaranteed to make untrained people extremely sore the next day.” Some of the group warmed up for 20 minutes on a stationary bike. Another contingent blew off the [...]

The FDA has some scary news for fans of energy drinks and weight-loss supplements. The stimulant called dimethylamylamine (DMAA), often used in supplements promising weight loss, muscle building and performance enhancement, has been shown to “elevate blood pressure and could lead to cardiovascular problems, including heart attack, shortness of breath and tightening of the chest.” Given the known biological activity of DMAA, the agency warns, the ingredient may be particularly dangerous when used with caffeine. An FDA news release reports [...]

Where you live may have more influence than you thought on how long you live. A recent report by researchers at Brown University has found that seniors living in the South Atlantic, East South Central and West South Central regions of the country — an area stretching from parts of Texas to South Carolina — had a 10 to 12 percentage point higher risk of receiving potentially harmful prescriptions than people in New England, who had the lowest chance. It’s [...]

Want to know why you should work out with music? The Wall Street Journal has some persuasive answers: when athletes synchronize their movements to a musical beat, their bodies can handle more exertion: Treadmill walkers have been shown to have greater stamina and cyclists require less oxygen uptake. Swimmers who listened to music during races finished faster than others who didn’t. What music does it best? The journal puts that question to Costas Karageorghis, deputy head of research at the [...]

Kicking out the jams, it turns out, can also kick out the germs. That’s the conclusion of researchers at McGill University, who reviewed 400 research papers in the neurochemistry of music, and found that playing and listening to music has clear benefits for both mental and physical health. According to a McGill news release, music was found both to improve the body’s immune system function and to reduce levels of stress. Listening to music was also found to be more [...]

The good news, from researchers at the University of Queensland, is that steroids really do relieve the pain of tennis elbow. The bad news is that because steroids relieve the pain of tennis elbow, the tennis player is more likely to overuse and re-injure the joint. A UQ news release reports that researchers at the school found that treating patients with physiotherapy and a corticosteroid injection did not reduce recurrence or have a long-term effect on complete recovery, pain or [...]

We all know that love hurts, but for many postmenopausal women, sex hurts more. That’s because lower estrogen render vaginal tissues thinner, drier and more fragile. Now comes FDA approval for a new drug, Osphena, which, in FDA speak, “acts like estrogen on vaginal tissues to make them thicker and less fragile, resulting in a reduction in the amount of pain women experience with sexual intercourse.” The FDA reports that three clinical studies involving nearly 1,900 postmenopausal women with signs [...]

The bad news is that the good news only applies to men whose prostate cancer has already spread to other parts of their bodies, and whose testosterone levels have been lowered by drug therapy. The good news is that for those men, a natural product called genistein-combined polysaccharide, or GCP, which is commercially available in health stores, could help keep them alive. A news release from the University of California at Davis reports that researchers at the school found that [...]
