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.

This research aimed to investigate the effect of one period of first division basketball competition on some immune system factors in elite female basketball players. For this reason, 20 basketball players with average age of 23 ±3 years, weight: 62.1± 9.50 kg, height:167.5 ± 5.04 cm, BMI:22.03 ± 2.09 kg/m2 and maximum oxygen uptake (VO2max): 41.70 ± 11.50 ml.kg.min were examined. Subjects were divided experimental group(10 selected players who attended actively as main individuals in league competitions) and control groups(10 first division basketball players who didn’t participate in competitions but continue to exercise 5 days a week for 1.5 h/d). Competitions program was as follow: in first week 3 competitions and after one week interruption, in third week 4 competition was carried out alternatively. Twenty four hours before first competition and 24 h after last competition blood sample was taken for measuring serum immunoglobulins (IgA, IgM, IgG) by using Neflometery method. Data analysis was done by dependent t- test and independent t-test for assessing mean changes in and between groups, respectively. Results showed that one period of first division basketball competition leads to significant increase in resting levels of serum IgA and IgG of elite basketball players while increase in IgM was not significant. Overall, it appear that immune system of basketball players was affected by physical and psychological stress at the end of competitions and this may Cause athletes catching upper respiratory tract infections.
