Note. RIF = Ramadan intermittent fasting; C = control group; E = experimental group; TV = tidal volume; VC = vital capacity; FVC = forced vital capacity; FEV1 = forced expiratory volume in 1 second; FEV1% = FEV1 as a percentage of FVC; FEF = forced expiratory flow rate; PEFR = peak expiratory flow rate. Values are M ± SD. One-way repeated measure analysis of variance showed insignificant difference.
