C. Haskinpopp et al., AEROBIC AND MYOCARDIAL DEMANDS OF LAWN MOWING IN PATIENTS WITH CORONARY-ARTERY DISEASE, The American journal of cardiology, 81(10), 1998, pp. 1243
Lawn mowing approximates 4 to 6 METs and may evoke heart rate and syst
olic blood pressure responses that approach and exceed these attained
during maximal exercise testing. The excessive cardiac demands may be
deceptively camouflaged by the moderate aerobic requirements and perce
ived effort.
