Effects of Ramadan fasting on 60 min of endurance running performance in moderately trained men.

Objective: This study examines the effects of Ramadan fasting on endurance performance.

Method: Using a crossover design, 10 moderately trained, active Muslim men performed 60 min runs on a treadmill in the fasted (Ramadan, RAM) and non-fasted (Control, CON) state on two separate counterbalanced occasions. After familiarization, four subjects performed their CON trial 1 week before Ramadan, while the other six subjects performed their CON trial 1 week after the Ramadan month.
