Year 2017, Volume: 28 Issue: 3, 128 - 134, 14.11.2017

Abstract

Bir MET, 3.5 ml.kg-1.dk-1 VO2’ye karşılık gelmekte
ve dinlenik metabolik hız (DMH) olarak kabul edilmektedir.
Bununla beraber 1 MET değerinin yüksek
olduğuna dair tartışmalar mevcuttur. Bu çalışmanın
üç amacı vardır; 1. DMH’nin kestiriminde SenseWear
Armband’ın (SWA) geçerliğini belirlemek, 2. indirekt
kalorimetrik yöntem (İKY) ve SWA ile belirlenen
DMH’nin MET sistemi ile aralarındaki farkları saptamak,
3. DMH’nin vücut kompozisyonu ile arasındaki
ilişkileri incelemektir. Araştırmaya 25-55 yaş
aralığında 28 erkek ve kadın gönüllü olarak katılmıştır.
DMH, İKY ile ölçülmüş ve eş zamanlı olarak SWA
ile enerji harcaması kayıt edilmiştir. VO2’nin kalorik
eşdeğeri Weir’in (1949) formülü ile belirlenmiştir.
SWA’dan belirlenen MET değerlerinin 1 MET’ten ve İKY
ile ölçülen dinlenik VO2’nin 3.5 ml.kg-1.dk-1 (1 MET)’ten
farkı Tek Örneklem t Testi, iki yöntem arasındaki
farklar Bağımlı Gruplarda t-Testi, değişkenler
arasındaki ilişkiler Pearson’un Korelasyon katsayısı
ile belirlenmiştir. SWA’dan saptanan MET (1.0 􀁲 0.12)
1 MET’e eşit (p>0.05), İKY ile ölçülen MET (0.83 􀁲 0.16)
1 MET’ten önemli derecede düşüktür (p<0.01). SWA’dan
ölçülen MET, İKY’den yüksektir (p<0.05). İki yöntemden
belirlenen MET değerleri arasındaki ilişki anlamlı
değildir (p>0.05). İki yöntemden ölçülen DMH değerleri
arasında anlamlı ilişki (p<0.01) saptanmış olmakla beraber,
SWA’dan ölçülen DMH, İKY’den yüksektir (p<0.05).
İKY ve SWA’dan belirlenen DMH ve vücut ağırlığı, beden
kitle indeksi, yağsız vücut kitlesi arasında anlamlı
yüksek ilişkiler saptanmıştır (p<0.05). Bu çalışmanın
bulguları İKY ile ölçülen DMH’nin 1 MET’ten önemli
derecede düşük olduğunu, SWA’nın DMH’yi yüksek
kestirdiğini ve İKY ile örtüşmediğini, her iki yöntemle
belirlenen DMH için en önemli vücut kompozisyonu
bileşeninin YVK olduğunu göstermiştir.

Validity of Senserwear Pro3 Armband to Estimate MET System and Resting Metabolic Rate

Year 2017, Volume: 28 Issue: 3, 128 - 134, 14.11.2017

Abstract

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.
