[Endocrine-metabolic adjustments during Ramadan fasting in young athletes].

The Islamic precept of R implies important physiological modifications due to the hydric and dietetic restrictions along a whole month plus a day, all of which have a crucial repercussion over the physical and intellectual performance of Muslims, particularly in occidental societies, in which there is no hour readjustments for daily activities. Among the imposed modifications by Ramadan in daily habits, intermittent fasting along day and night causes adaptation mechanisms to optimize the energy consumption. The objective of this study was to analyze the metabolic-endocrine changes that happen during daily working hours, along the month of fasting in young subjects who have to continue their usual activities and sport training.
