Low push-up capacity may indicate heart disease risk: Study

Active, middle-aged men able to complete more than 40 push-ups may be at significantly lower risk of cardiovascular disease (CVD) outcomes -- including major events such as heart failure, a study has found.

The research, published in the journal JAMA Network Open, showed that push-up capacity can be a good indicator of heart health.

"Our findings provide evidence that push-up capacity could be an easy, no-cost method to help assess cardiovascular disease risk in almost any setting," said Justin Yang, of Harvard T H Chan School of Public Health in the US.

"Surprisingly, push-up capacity was more strongly associated with cardiovascular disease risk than the results of submaximal treadmill tests," Yang said.

Objective assessments of physical fitness are considered strong predictors of health status; however, most current tools such as treadmill tests are too expensive and time-consuming to use during routine exams.

This is the first known study to report an association between push-up capacity and subsequent cardiovascular disease outcomes.

The researchers analysed health data from 1,104 active male firefighters collected from 2000 to 2010. Their mean age was 39.6 and mean body mass index (BMI) was 28.7.

Participants' push-up capacity and submaximal treadmill exercise tolerance were measured at the start of the study, and each man subsequently completed annual physical examinations and health and medical questionnaires.

During the 10-year study period, 37 CVD-related outcomes were reported. All but one occurred in men who completed 40 or fewer pushups during the baseline exam.

The researchers calculated that men able to do more than 40 push-ups had a 96 per cent reduced risk of CVD events compared with those who were able to do less than 10 push-ups.

Push-up capacity was more strongly associated with lower incidence of cardiovascular disease events than was aerobic capacity as estimated by a submaximal treadmill exercise test.

Since the study population consisted of middle-aged, occupationally active men, the results may not be generalisable to women or to men of other ages or who are less active, note the authors.

"This study emphasizes the importance of physical fitness on health, and why clinicians should assess fitness during clinical encounters," said Stefanos Kales, a professor at Harvard.
