Effects of Ramadan fasting on substrate oxidation, physiological and perceptual responses during submaximal intensity running in active men
Those of the Islamic faith are obliged to fast on a daily basis for 30 consecutive days during the holy month of Ramadan. Throughout this month, healthy Muslims mandatorily undergo total abstinence of food and fluid from dawn-to-dusk daily as a religious duty.
The primary aim of this study was to re-examine the effects of Ramadan fasting on whole-body substrate utilization, physiological and perceptual responses during 30 min of continuous running at a submaximal exercise intensity of 65 % VO2max in active male Muslim runners. Concerted effort has been undertaken to control and/or account for the participants’ composition and amount of food as in the real world, ecologically valid Ramadan fasted and non-fasted conditions.
In conclusion, Ramadan fasting has no major impact on substrate utilization and is not an effective ‘fat-burning’ enhancing activity to lose fat mass. Running in the Ramadan fasted state led to a greater psycho-physiological stress compared to the same run in the non-fasted state. > From: Aziz et al., Sport Sci Health 10 (2014) 1–10.
