a study by researchers at the Harvard T.H. Chan School of Public Health suggests that middle-aged people who have about 40 push-ups have a much lower chance of suffering heart disease.
The researchers followed 1,100 middle-aged firefighters for over 10 years, tracking how many push-ups they could do – as well as their performances on treadmills.
The study showed that 40 push-ups were 96% less likely to contract heart disease than those who could do 10 push-ups.
"Our findings provide evidence that there is no easy way to help assess cardiovascular disease risk in almost any setting," said lead author Justin Yang.
"Surprisingly, push-up capacity was more strongly associated with cardiovascular disease risk than the results of submaximal treadmill tests."
The study highlighted, however, that since the test was done, active firefighters, the results can not be extended to other groups, such as those who are less active.
