Among the grimmer reasons to get it shape is this
news from researchers at Johns Hopkins: higher levels of physical fitness may not only reduce risk of heart attacks and death from all causes, but also possibly improve the chances of survival after a first attack. A Johns Hopkins news release reports that researchers at the school studied the medical records of people who had taken a treadmill stress test before their first heart attack and used the patient’s achieved metabolic equivalent score — MET, for short — as a quick, although not perfect, measure of energy consumption at rest and during physical activity. The higher the MET score, the more physically fit the participants were considered to be. MET scores range from 1 to 12, where 1 is considered the equivalent of sitting on the couch, 3 aligns with walking, 7 with jogging, 10 with jumping rope and 12 with sprinting. The researchers found that overall, the 634 people achieving MET scores of 10 or higher had about 40 percent fewer deaths after a first heart attack as compared to the rest of the patients. They also found that one-third of the 754 patients with a MET score of 6 or less died within a year of their first heart attack. Overall, their results showed an 8 percent reduction in death risk for each whole-number increase in MET score after a first heart attack.
