Lack of Fitness, Not Too Much Sitting, Shortens Lives

A new study published at Dr. Gabe Mirkin’s site suggests that it is the level of fitness, not time spent sitting that predicts susceptibility to disease and longevity.

In a study from Norway, the authors followed 495 women and 379 men, aged 70 to 77 years. They measured sitting time with accelerometers and heart-lung fitness by peak oxygen uptake (VO2 peak). They found that:

  • People who spent 12-13 hours sitting each day were 75 percent more likely to have heart attack risk factors (high blood pressure, obesity, diabetes, high cholesterol, high waist circumference, high triglycerides, reduced good HDL cholesterol, high blood pressure, and high fasting blood sugar levels).
  • The most fit people were more than 40 percent less likely to have abnormal heart attack risk factors, even if they sat for 12 to 13 hours a day and did not meet the criteria for the recommended amount of exercise done each day.
  • People who exercised, but were not physically fit, were not protected from the heart attack risk factors.
