Effect of Ramadan fasting and triangular exercise progressive on the vigilance, mood and blood glucose in trained athletes

This study has for objective the assessment of the vigilance, mood states variations and the blood glucose levels, during a triangular effort progressive in trained athletes during Ramadan fasting (RF). Methods. Ten trained male athletes aged 21.8 ± 1.1 years are evaluated before (B.RF), during (1st, 2nd and 3th week) and after Ramadan fasting, in the blood-glucose, vigilance, and mood states at rest and after (A. Ex.) a triangular exercise test (TUB II).Results. Comparing to the reference period (B.RF), the RF induces a decrease in the maximal aerobic power (TUB II) approximately 2- 5% and a hypoglycaemia. The objective vigilance is doubly influenced by the RF (F= 14.58, p
