No, You Probably Won’t Drop Dead While Exercising

Dropping dead while exercising is a common fear, especially among middle-aged men. Unfortunately there have been limited data on the precise rate of sudden cardiac arrest (SCA) in middle-aged people and little understanding about the medical history of the victims of SCA.

Exercise: Can There Be Too Much Of A Good Thing?

Exercise And The Limitations Of Observational Studies

Last week I wrote twice about exercise. Strictly speaking, both stories were complete lies. The first story was about a study published in the Lancet which analyzed data from more than 10,000 patients at 2 VA Medical Centers and found that patients with high fitness levels were less likely to die than patients with low fitness levels. The pattern held…

First, a study in PLoS One provided ammunition to the exercise-averse crowd by claiming that exercise can actually be bad for some healthy people.
