Introduction: 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-Cleanup Messy Code 5% and a hypoglycaemia. The objective vigilance is doubly influenced by the RF (F= 14.58, p<0.002) and the exercise (F = 13.04, p<0.02), and decreasing significantly during the 1st and 2nd week of RF. However the subjective vigilance and moods states are not varied neither by the RF nor by the exercise. Conclusion: The results should guide the work of physical education teachers and coaches to a programming by integrating more of periods of complete recovery, and avoiding risky tasks requiring sustained attention.
