The Year in Fitness

If all the Phys Ed columns published this year have a single message, it is that now is a fine time to own a body. The diverse exercise-related experiments published in 2011 and covered in this space each week suggest that it’s possible to retain your cognitive powers, muscle mass, running speed and waistline, even as you age, and that a little exercise can go a long way in terms of physiological benefit. Recent, important science even tells us that coffee, chocolate and beer enhance exercise performance, which is fortunate, since I have no plans to give up any of those. As most of us prepare our exercise resolutions for 2012, now seems an ideal time to review the past year in fitness science and the lessons it contained, both encouraging and cautionary.

For the first time ever, a government advisory board is asking scientific journals not to publish details of certain biomedical experiments, for fear that the information could be used by terrorists to create deadly viruses and touch off epidemics.

Metal Hips Failing Fast, Report Says

A British registry found that the highest failure rates involved the Articular Surface Replacement device, which was recalled.

PARIS — Health officials in at least a half-dozen countries are grappling with the intense anxiety of tens of thousands of women who received breast implants that were made in France with substandard silicone — and that have been rupturing at unusually high rates.

A Medical School More Like Hogwarts
