The purpose of this study was to investigate the effect of eight weeks high intensity interval training and spirulina supplementation on humoral immune system, cardio respiratory fitness and body composition of overweight women. 30 inactive students (height (cm): 161. 7 ± 2. 8, weight (kg): 75.76 ± 8.43, age(y): 25. 06 ± 6. 66) were divided into three groups (placebo - HIIT, spirulina - HIIT, spirulina). Exercise groups performed HIIT for 8 weeks (3 sessions per week with 4-7 repetitions in each session () in intensity of 90% of the maximum heart rate). Supplementation groups received 6 g spirulina powder per day. Fasting blood samples were collected before and after 8 weeks to determine the levels of IgA and IgG. A significant reduction was observed in BMI, WHR, body fat percentage and significant increase in body fat free mass, VO2max, IgA in all three groups. There was a significant elevation in IgG level in the placebo - HIIT and spirulina - HIIT (P=0. 001, t=-6. 77) groups. However, there was no significant difference in IgG levels between the pre and post supplement consumption in the spirulina group (P=0. 07, t=-1. 54). In general, the results of this study showed that 8 weeks of HIIT and supplementation of spirulina increase the function of the immune system and respiratory cardiovascular fitness. Also, 8 weeks of HIIT and spirulina supplementation cause of weight loss and increase fitness by decreasing BMI, WHR, body fat percentage and increase body fat free mass in women.
