For men over 40, vigorous exercise could prove deadly
For men competing in triathlons past the age of 40, the grueling slog to the finish line could be their last.
As the average age of competitors in endurance sports rises, a spate of deaths during races or intense workouts highlights the risks of excessive strain on the heart through vigorous exercise in middle age. Among the recent casualties: Michael McClintock, senior managing director of Macquarie Group Ltd. and a triathlete, who died at 55 of cardiac arrest this month after training.
"People need to understand that they're not necessarily gaining more health by doing more exercise," said David Prior, a cardiologist at the University of Melbourne in Australia.
Though benefits of exercise are well-known, researchers now suspect there may be a point at which exertion becomes dangerous, especially for middle-aged men who, because of gender and changes that accompany aging, are more susceptible to cardiac arrest caused by vigorous exercise. - Bloomberg News
