To find the association between all-cause mortality and cardiorespiratory health in patients undergoing treadmill testing, researchers studied 122,007 patients between January 1, 1991 up to December 31, 2014, and divided them into five performance groups or levels of fitness.

The study was published Friday in the journal JAMA Network Open.

In a new study, researchers found just how important exercise is when it comes to long-term mortality.

"Aerobic fitness is something that most patients can control". "Everyone should be encouraged to achieve and maintain high fitness levels". He says we need to warn that simply being unfit (out of shape) should be considered just as strong a risk factor for mortality as diabetes, smoking, and hypertension.

"There is no level of exercise or fitness that exposes you to risk", he said.

Several recent studies have suggested associations between extreme exercise and certain adverse cardiovascular findings, such as atrial fibrillation and coronary artery disease.

Musk has previously said that his tunneling company " started out as a joke " and admitted that the project might fail. Musk, a space entrepreneur and electric-car pioneer, has pledged to complete the test tunnel by the end of the year.

"In this study, the most fit individuals did the best", said Metzl, who was not involved in the study.

Dr Wael Jaber, co-author of the study, called the results surprising. "We've never seen something as pronounced as this and as objective as this".

The researchers noted that whole people of all ages and both genders benefitted from exercise, women benefited more than men.

"If you compare the risk of sitting versus the highest performing on the exercise test, the risk is about three times higher than smoking", Jaber explained. In younger age groups there was no statistical difference in outcomes between elite and high performers.

Comparing somebody who doesn't exercise much to somebody who exercises regularly, he said, still showed a risk 390% higher. For all other comorbidity subgroups there was no statistical difference in survival rates between the elite and high performers. The researchers looked at the possibility of diehard gym rats and marathoners being at risk from pushing themselves too hard, but found that there's no link between an abundance of exercise and an early grave.

Cleveland Clinic is a nonprofit multispecialty academic medical center that integrates clinical and hospital care with research and education. "Once cleared by their physicians, patients shouldn't be afraid of exercise intensity".
