Stage 1; Physical demands of vacuuming in women using different models of vacuum cleaners

Physical Demands of Vacuuming in Women Using Different Models of Vacuum Cleaners:

This is a study about the increasing level of women having a primary responsibility to take care of the household. The reason for  this study was to evaluate the energy expenditure and hemodynamic responses associated with vacuuming using five different ways of vacuuming. NORMAN, JOSEPH F.; KAUTZ, JEFFREY A.; WENGLER, HEATHER D.; LYDEN, ELIZABETH R. took thirty-six health women from the ages 50-59 and measured the energy that was exerted by indirect calorimetry using an Aerosport KB1-C portable metabolic system. After that they collected the baseline HR, blood pressure (BP), and oxygen consumption data, subjects performed vacuuming and treadmill by walking in one of six different sequences. Vacuuming consisted of using five different ways of vacuum cleaners, three upright models and two canister model for 6 min each. The treadmill walking  was conducted at 2.0 mph for 6 min. O2, HR, BP, and RPE were recorded during each task. The rate-pressure product  was calculated to estimate myocardial oxygen demand. The result was that vacuums with the self-propelled upright model results in lower levels of O2, RPE, HR, systolic BP, and RPP responses compared to the other models.
