Abstract

This study assessed: 1) the effect of fasted and non-fasted states on the relationships between RPE and VO2, HR VE during treadmill and cycling GXT; 2) the effect of fasted and non-fasted states on the affective state during the cycling and treadmill GXTs. Ten Muslim male physical education students (22.3 ± 1.5 y) volunteered for the study. Each student performed two GXTs while fasting during Ramadan (one on the treadmill and one on the bike) and the same two GXTs while not fasting after Ramadan. The relationships between the RPE and VE, the RPE andVO2 and the RPE and HR were significantly higher (P < 0.05) in the non-fasted state compared to the fasted state (R2 = 0.946 & R2 = 0.872; R2 = 0.949 & R2 = 0.866; R2 = 0.949 & R2 = 0.829, respectively). There was no significant difference in the affective state between the fasted and non-fasted states (P > 0.05). RPE responses during the GXTs on treadmill and bike were affected during Ramadan fasting compared to a non-fasting state after Ramadan. This has very important implications especially when considering that there are numerous studies that have used sub-maximal RPE and VO2 to predict V O2max. This may be due to the lower glucose level during Ramadan fasting as indicated by the lower respiratory exchange ratio in the fasted compared to the non-fasted state. However, the GXTs on treadmill and bike during Ramadan fasting were felt to be as pleasant as when not fasting after Ramadan.
