Researchers suggest that risks must be conveyed to the general public of being unfit should be considered a strong of a risk factor as is smoking, diabetes, and hypertension if not stronger than all of them; and should be treated as a disease that can actually be cured with the prescription of exercise. On a related note, the study also looked at the potential risk of being overactive. In addition, he states that researchers, in the past, have expressed consistent concern about "ultra exercises" but this study assures there is no need for it.
"There is no level of exercise or fitness that exposes you to risk", he said.
Comparing somebody who doesn't exercise much to somebody who exercises regularly, he said, still showed a risk 390 percent higher.
"We were particularly interested in the relationship between extremely high fitness and mortality" said Kyle Mandsager, M.D., an electrophysiology fellow at Cleveland Clinic and the lead author of the study.
The benefits of exercise were seen across all ages and in both men and women, "probably a little more pronounced in females", Jaber said.
However, according to the study, individual patients should always check with their healthcare provider before starting an exercise programme. Then, using social security and medical records, they tracked if and when the patients died. "This is us testing them and figuring out objectively the real measure of what they do". The risk of dying was twice as much among those who fared poorly on the treadmill compared to those who had kidney failure on dialysis.
Risk factors of sedentary lifestyle were found to overwhelm strong risk factors such as those for diabetes, smoking, and some end stage diseases. "There's no age limit that doesn't benefit from being physically fit". Compared to those in the top percentile those with sedentary lifestyles were associated with 500% increased risk for death. In those over the age of 70, elite performers had a almost 30 percent reduced risk of mortality compared to high performers. Sure, exercise contributes to better health, but not all workouts are the same, and different bodies benefit from different types of exercise. "It's reversible", he explained, adding that doctors are really good at treating patients who have had cardiovascular events but they can be prevented. "It's all about getting up and moving".
