| Summary: | 0.2408 at 16 lifts/min). Furthermore, negative physical accurately simulate a repetitive manual material handling and psychological effects associated with wearing the comparing estimated versus measured working V. 02 effect of wearing the Oxylog System from Morgan Scientific, equations. Average percent difference between value estimated using linear regression from the submaximal found that there was a difference between the average heart rate values for 16 lifts/min (p = 0.0 1 6); heart rates were consistently higher during the tests however, at 8 lifts/min, the difference was not Inc. during a series of four manual material handling tests. increase in difficulty when lifting and lowering while indicates that there was no difference between V. 02 lift rates (8 and 16 lifts/min) for an hour duration each. lifts/min and was statistically significant (p=0.000 1). material handling environments. Heart rate was directly measured during all four tests; for two tests, the Oxylog of variance (ANOVA) results for working heart rate Oxylog were reported. Participants expressed an positive 67% for 8 lifts/min and a positive 9' )% for 16 predicted by Garg and measured by the Oxylog was a rate. Energy expenditure during the task was compared resulting heart rate data was compared to the heart rates resulting when the participant wore only the heart selected to resemble the work rates commonly observed in significant (p = 0. 109). Statistical analysis step test and a series of four lifting tests at two different step test results. The averages of the participants' system was worn to directly measure the working V. 02; the task commonly found in industry settings. Lift rates were The lift test protocol used in this study was designed to The lift tests were performed by 12 males (average age of 23 This purpose of this study was to evaluate the prolonged to Garg's metabolic energy expenditure prediction watch. For this test design, V. O2 values were wearing the Oxylog, particularly at the faster lift while the Oxylog was worn compared to when it was not while wearing the Oxylog for both lift rates. Analysis worn for both lift rates (p = 0. 1081 for 8 lifts/min; p years); each participant completed a 15-minute submaximal |
