  • Title: Activity, energy metabolism and postnatal age relationship in low-birth-weight infants.
    Author: Rubecz I, Mestyán J.
    Journal: Acta Paediatr Acad Sci Hung; 1975; 16(3-4):351-62. PubMed ID: 1224981.
    Abstract:
    The relationship between heat production and different activity levels was examined in 30 low-birth-weight (premature and small-for-gestational age) infants. A low level of spontaneous activity was preponderant, with a gradual shift from activity scores near zero to higher intensities with increasing postnatal age. There was a close correlation between activity and heat production. Older infants displayed a greater amount of spontaneous activity and a larger variation in heat production and activity-intensity relationship. The rise in heat production at a given activity intensity was greater in older than in younger infants indicating that the energy cost of identical activity increases with postnatal age. "Maximum" oxygen consumption increased with postnatal age.
