The aim of the present study was to evaluate the effect of saffron consumption and intermittent aerobic exercise on the spirometryand physiological parameters and blood pressure in non-athletic boys. Accordingly, in a quasi-experimental, double-blinded study, 40 healthy non-athlete male volunteer students of University of MohagheghArdabili(mean age 19.91±3.43 years) were selected by convenience sampling method and were randomly divided into 4 groups (each 10 subjects): exercise-placebo, exercise-supplement, supplement and placebo. Supplement and exercise-supplement groups daily consumed a capsule containing 30 mg of saffron powder for 3 monthswhile placebo group consumed placebo. A spirometry was conductedone day before and also after the supplement and placebo protocol. Also, SBP, DBP, heart rate, mean arterial pressure (AMP), pulse pressure, and (the number of breaths in a minute) were collected and data were recorded. For data analysis, paired-sample ttest was used for intra-group comparisons and one-way analysis of variance test (ANOVA) was applied for inter-group comparisons at the significance level (P≤0.05). The results showed that 3 saffron consumption for 3 months and intermittent aerobic exercise increased lung volumes and capacities (P<0.001) and reduced systolic and diastolicblood pressure, heart rate, the number of breaths in a minute (P<0.001). Also, results showed no significant differences between exercise-saffron and saffrongroups in FVC, PEF, FEV1, FIV1 and exercise-saffron and exercise-placebo groups in MVV and PIF. According to theseresults, saffron supplementation and exercise can probably have beneficial effects as clinical applications in the treatment and prevention of respiratory diseases and hypertension.
