In a “warning” letter published in the Dec. 5 JAMA, researchers at Yale University School of Medicine caution that weightlifting could be a possible cause of aneurysms and aortic dissection. After treating five cases of weightlifters with aortic dissection over a two-year period, a cardiothoracic surgeon at Yale-New Haven Hospital hypothesized that each of the five patients’ aortas was unable to withstand the “spike” in blood pressure that accompanies the strain of powerlifting. The Associated Press notes that five cases does not constitute proof of a link between weightlifting and aortic dissection, but researchers say the cases should teach weightlifters to be cautious during workouts, especially since the causes behind aortic weakening are “not well understood.” Researchers recommend that weight trainers lift only 50% of
their body weight and undergo aortic imaging to detect possible aneurysms (Dreyfuss, AP/Hartford Courant, 12/15)
So for all of you 200 pounders, make sure you never bench, squat or deadlift more than 100lbs.
