The New York Times multimedia team gets conceptual in this slide show of six Olympic athletes with very different body types, and very different biostats, starting with shot-putter Christian Cantwell, who weighs 335 pounds and bench presses 650. Amazing stuff.
Walnuts, of all things, appear to slow the growth of prostate cancer tumors–in mice at least. Researchers at the University of California at Davis have found that mice genetically programmed to develop prostate cancer had smaller, slower growing tumors if they consumed a diet containing walnuts. A U.C. Davis news release reports that when researchers at the school, working with colleagues at the USDA Western Regional Research Center in Albany, Calif., studied tumor size in mice fed different diets for [...]
Read more →Yes, it feels good, and yes, it can be pricey, but massage also does some important muscle reclamation work after a particularly tough workout. Researchers at the Buck Institute for Research on Aging at McMaster University in Hamilton Ontario conducted genetic analysis of muscle biopsies taken from the quadriceps of eleven young men after they had exercised to exhaustion on a stationary bicycle. A McMaster news release reports on the research, for which one of their legs was randomly chosen [...]
Read more →The findings are preliminary, but they are also provocative: research conducted at the University of California at San Francisco suggests that men who do vigorous exercise three times a week have an increase in the expression of certain genes that are known to suppress tumors, including some breast cancer tumors that similar to prostate cancer tumors. HealthDay reports that when researchers compared prostate genes from 70 men with low-risk prostate cancer to normal prostate genes from 70 men they found [...]

Obese people hurt even more: 68 percent more for Obese 1 group, 136 percent more for Obese 2 group, and 254 percent more for Obese 3 group, as defined by the World Health Organization. A Stony Brook news release reports that when researchers at the school analyzed data about body mass index and the experience of [...]

Researchers at Northwestern University have published a study in the New England Journal of Medicine asserting that the common medical practice of focusing on the next ten years of a patient’s life has been giving people a false sense of security about their chances of having a heart attack or stroke. A Northwestern news release reports that when the scientists measured risk factors for cardiovascular disease — blood [...]
Read more →Kettlebells, known as “girya” in their native Russia, are basically cannonballs with handles attached to them, and they’ve been used as long as anyone can remember to train Russian athletes. Now researchers in Denmark have found something else they’re good for: pumping up core muscles so well that back pain is significantly reduced. The New York Times reports on the Danish study, in which 40 middle-aged women with back and shoulder pain were randomly assigned to one of two groups. [...]

Driving and texting at the same time is understood to be dangerous, if not deadly. But what about walking and texting? Researchers at Stony Brook University put 33 men and women, all experienced texters, through a simple test to see how much texting would influence walking. A Stony Brook news release reports that the test subjects were shown a target on the floor eight meters away. Then, after obstructing vision of the target and floor, they were told to walk [...]

The question of how much training is too much training is a tough one, but as Gina Kolata warns in her Personal Best column, it’s an important one, because overtraining is worse than under training. In fact, it can be worse than no training at all. Kolata quotes William Kraemer, a professor of kinesiology at the University of Connecticut, explaining that “People think a good workout is, ‘I am in a pile of sweat and puking.” Wrong. John Raglin, a [...]
