Bu
çalışmanın amacı, Dünya Sağlık Örgütü (World Health Organization; WHO) ve Amerikan Spor Hekimliği
Koleji (American
College of Sports Medicine; ACSM) tarafından önerilen formüle
dayalı pratik enerji tüketimi hesaplamalarının istirahat metabolizma hızı ve
egzersize ait sonuçlarını solunumsal parametrelerle elde edilen enerji tüketimi
düzeyleriyle karşılaştırmaktı. Çalışmaya 23,94±6,70 yaş ortalamasına sahip 35
sedanter kadın gönüllü katıldı (Boy:166,66±6,10 cm; VK: 66,77±11,64 kg; VKİ:
23,97±3,4). İstirahat analizlerinin ardından tüm gurup vücut kütle indekslerine
göre normal (n=20) ve fazla kilolular (n=15) olmak üzere ikiye ayrıldı (VKİ
sırasıyla 21,41±1,53 ve 27,39±1,76). Her katılımcı için istirahat ve 30
dakikalık 8 MET’lik egzersize ait toplam enerji tüketimi düzeyleri; hem VO₂
yanıtları, solunum değişim oranına ait enerji eşitliği ve zaman üzerinden, hem
de WHO ve ACSM eşitlikleri kullanılarak hesaplandı. İkili karşılaştırmalarda
ilişkili guruplar t-testi kullanıldı. Yalnızca fazla kilolu kadınlarda ACSM (1928,64±256,61
kal) eşitliğiyle tahmin edilen istirahat metabolizma hızlarıyla solunumsal
parametrelere dayalı olarak hesaplanan değerler (1868,99±223,17 kal) arasındaki
farklar anlamlı değildi (p=0,342). Normal kilolu kadınlarda WHO ve ACSM
eşitlikleriyle hesaplanan istirahat metabolizma hızı değerleri, laboratuvar
ölçümlerine kıyasla oldukça düşük sonuçlar verdi (p=0.001). 30 dakikalık
egzersizlere ait toplam enerji tüketimi düzeyleri adına ne WHO ne de ACSM
eşitlikleriyle hesaplanan değerler, ne normal ne de fazla kilolu kadınlar için
toplam enerji tüketimlerini doğru tahmin edemedi (p≤0,019). Çalışmanın
sonuçlarına göre, fazla kilolu kadınların istirahat metabolizma hızlarını
değerlendirmede [(MET*3,5*VK (kg))/1000]*5*t(dk) eşitliğinin kullanılabileceği, ancak
egzersizlere ait enerji tüketimi düzeylerinin belirlenmesinde solunumsal
parametrelere dayalı analizlerin yapılmasının zaruri olduğu değerlendirildi.
