 <\/p>\n

For most people, doing housework is a dreaded chore. But for some people<\/p>\n

with certain health conditions, it can be harmful.<\/p>\n

As Joe Norman, Ph.D., associate professor, University of Nebraska Medical<\/p>\n

Center School of Allied Health Professions, and his colleagues worked with<\/p>\n

patients in a cardiac rehabilitation clinic a few years ago, they noticed<\/p>\n

some patients complaining about having angina when at home vacuuming. Angina<\/p>\n

causes chest pain or discomfort due to heart disease. It occurs when the<\/p>\n

heart muscle (myocardium) doesn’t get as much blood (hence as much oxygen)<\/p>\n

as it needs.<\/p>\n

Its also a sign that someone is at increased risk of heart attack,<\/p>\n

cardiac arrest and sudden cardiac death.<\/p>\n

We noticed some people were telling us they had problems vacuuming<\/p>\n

versus other similar physically demanding activities, said Dr. Norman,<\/p>\n

principal investigator of the study. They could walk 15 to 30 minutes<\/p>\n

at a brisk pace but would get angina (chest pain) when they would vacuum.<\/p>\n

It raised the question that something might be going on was related<\/p>\n

to the use of the upper extremities.<\/p>\n

UNMC researchers set out to compare the estimated myocardial oxygen<\/p>\n

consumption and energy expenditure associated with vacuuming using five<\/p>\n

different vacuum cleaner models.<\/p>\n

Dr. Norman, who also specializes in cardiovascular physiology, said<\/p>\n

its important that workload on the heart doesnt exceed the oxygen supply<\/p>\n

to the heart. If the amount of oxygen needed for the heart muscle to perform<\/p>\n

tasks is out of sync with the amount of oxygen being supplied, angina occurs.<\/p>\n

Vacuuming requires the work of both the upper and lower extremities.<\/p>\n

Results of the study were published recently in the American College<\/p>\n

of Sports Medicines Medicine and Science in Sports & Exercise journal.<\/p>\n

Researchers also have presented their findings at a meeting of the American<\/p>\n

Association of Cardiovascular and Pulmonary Rehabilitation.<\/p>\n

Thirty-six healthy women without heart disease between the age 50 and<\/p>\n

59 tried out each vacuum cleaner for six minutes with rest in between.<\/p>\n

Women were used in the study because studies continue to show they have<\/p>\n

the primary responsibility for housekeeping even after a cardiac event.<\/p>\n

Measurements of heart rate, blood pressure, oxygen consumption data<\/p>\n

and rating of perceived exertion were measured in the study participants<\/p>\n

before and after vacuuming. They tested the energy required to operate<\/p>\n

five models of vacuums three upright and two canister styles. They included<\/p>\n

self-propelled upright, a canister style with a power-head spinning brush,<\/p>\n

a lightweight upright, heavyweight upright and a compact canister.<\/p>\n

 <\/p>\n

Researchers found the best model to reduce the demand on the heart<\/p>\n

was the self propelled, which is least demanding for someone with a heart<\/p>\n

disorder.<\/p>\n

We found the vacuum cleaner model with some type of power assistance<\/p>\n

has significant impact on lowering the demand on the heart, Dr. Norman<\/p>\n

said. These types of features should be taken into account when making<\/p>\n

recommendations for patients with limited capacity or those needing to<\/p>\n

limit physiological stress due to a disease state.<\/p>\n

He said the second best vacuum they found was the canister model with<\/p>\n

spinning brushes.<\/p>\n

Based on their findings, researchers hypothesize that if individuals<\/p>\n

with cardiovascular disease could walk on a level treadmill at 2 mph without<\/p>\n

angina, they may also be able to use a power assisted vacuum model without<\/p>\n

experiencing angina. However, researchers say if people experience angina<\/p>\n

while using power assisted models, or while walking on the level at 2 mph,<\/p>\n

may need to avoid vacuuming.<\/p>\n

Researchers also said personal preference for a certain vacuum does<\/p>\n

not correlate with reduced energy demand. Unfortunately, you cant just<\/p>\n

go try out a vacuum cleaner, Dr. Norman said. You have to look to see<\/p>\n

if it has power assistanceself-propelled. Thats more important than having<\/p>\n

a certain preference for a vacuum cleaner.<\/p>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"
