Dinlenik metabolik hız MET Sensewear Armband İndirekt kalorimetri
One metabolic equivalent (MET) corresponds to
3.5 ml.kg-1.min-1 VO2 and is accepted as the resting
metabolic rate (RMR). However, there have been arguments
related with VO2 equivalent of 1 MET (3.5 ml.kg-1.
min-1); some arguments indicated that this value is relatively
high and may lead to misclassification of physical
activities. The present study has 3 purposes: 1. to
determine the validity of SenseWear Armband (SWA)
in predicting RMR; 2. to assess the differences between
the MET system and RMRs determined by SWA and indirect
calorimetry (IC) and 3. to evaluate the associations
between body composition and RMRs determined
by the two methods. Twenty-eight men and women
(age range:25-55 yrs) participated in the study voluntarily.
RMR was determined by IC by measuring VO2
and CO2. Energy consumption was recorded simultaneously
with SWA. Caloric equivalent of VO2 was determined
by Weir’s equation (1949). Differences between 1
MET and SWA-measured MET values and between resting
VO2 measured by IC and 3.5 ml.kg-1.min-1 were de-
termined by One-Sample t-test; differences between the
two methods were determined by Paired-Samples t- test;
and associations between the variables were determined
by Pearson’s correlation coefficient. SWA-measured MET
(1.0 0.12) was equal to 1 MET (p > 0.05), whereas IC-measured
MET (0.83 0.16) was lower than 1 MET (p<0.01).
SWA-measured MET was higher than IC-measured MET
(p<0.05). The association between MET values determined
by the two methods was not significant (p>0.05).
Although significant correlation (p<0.01) was found between
RMRs (kcal.day-1) measured by the two methods,
SWA-measured RMR was higher than IC-measured RMR
(p<0.05). Significant correlations were found between
both IC and SWA-measured RMRs and body weight, body
mass index and lean body mass (p<0.05). Results of this
study showed that; RMR measured by IC was significantly
lower than 1 MET, SWA overestimated RMR compared to
IC method, and LBM was the most significant body composition
component associated with RMRs determined
by both methods.
