The purpose of this study was to investigate the effect of high intensity interval training with Nigella Sativa supplementation on lipid profile, blood sugar and body composition of overweight young women.

The present study is in the form of a semi-experimental design in a double-blind on 48 overweight young women of NEISHABOUR city with a mean and standard deviation of age 36.41 ± 3.51 and body mass index of 28.704 ± 0.79. kg/m2. The subjects were randomly divided into four groups. Five people refused to continue cooperation due to some reasons and finally there were four groups including exercise and supplement (n=10), exercise and placebo (n=9), supplement (n=12) and placebo (n=12). Two exercise groups trained for six weeks, three sessions per week with an intensity of 85 to 95 percent of the maximum heart rate (HRmax). In addition to all of the groups consumed one oil capsule containing 1000 mg of Nigella Sativa or placebo (paraffin oil) before lunch daily. The Supplement and placebo group did not do any regular exercise. Anthropometric measurements and blood samples were taken on two occasions, pre-test and post-test. Fasting blood samples were collected from brachial vein to evaluate lipid profile and blood sugar levels. In order to check the normality of the data distribution, the Shapiro-Wilk test was used. To analyze the data and report them, multivariate analysis of covariance (MANCOVA) and univariate analysis of covariance (ANCOVA) tests and SIDAK post hoc test were used at a significance level of 0.05.

The results of the present research did not show a significant difference between exercise and supplement, exercise and placebo groups compared to supplement and placebo groups after six weeks in total cholesterol (p=0.332), triglyceride (p=0.928), high-density lipoprotein (p=0.86), low density lipoprotein (p=0.393) and fasting blood sugar (p=0.054). The results of the SIDAK post hoc test showed that, in total, the measures taken in the experimental groups have led to a decrease in body mass index, waist circumference, waist-to-hip ratio, and body fat percentage. In terms of body mass index and body fat percentage, the exercise and placebo groups had better performance, and in terms of waist circumference and waist-to-hip ratio, the supplement group had better performance, but these differences were not statistically significant (P ≤ 0.05) and all experimental groups only had a better score body mass index, waist circumference, waist-to-hip ratio and body fat percentage indices compared to the control group (placebo) (P < 0.05).

It seems HIIT and Nigella Sativa supplementation, each one can be effective in improving the body composition of overweight young women. However, in this study, HIIT and Nigella Sativa supplementation did not have a significant effect on lipid profile and fasting blood sugar, so it is suggested that more research should be done.

The aquaporin5 (AQP5) is an integral membrane protein that plays an important role in maintaining water homeostasis in the lung during of puberty. The purpose of this study was to evaluate the effect of period of reduced training with Nigella Sativa (NS) supplementation on AQP5 levels in the lung of Male Wistar rats during of puberty. 110 newborn three-week old male Wistar rats with average weight of 68±9 gr, were randomly divided into three groups included; the base, control and training groups. After a 6-week training period, the control group was divided into 2 groups with and without NS and training groups were divided into 6 groups including frequency, volume and intensity taper with and without NS. After 6 weeks, NS supplements were fed daily by gavages to groups of NS 500 mg/kg body weight. Progressive interval training was performed in 6 sessions, 30 minutes each session at a speed of 15 to70 meters per minute, Then, taper phase for three weeks in decreasing pattern, intensity, frequency and volume were performed. AQP5 levels were measured by ELISA methods. Analyzed is done with two-way ANOVA and LSD test at α≤0.05. While NS supplementation were increase average AQP5 levels in the taper groups of frequency, volume and intensity, But, there were no significant differences (P≥0/45) between AQP5 levels in with and without NS groups. Furthermore, three-week taper versus two weeks taper a significant increase the average AQP5 levels in the groups of with and without NS. It is suggested that the antihistaminic and antinociceptive effects of the NS with a period of reduced training with increasing levels of AQP5 would improve the physiological and functional parameters of the lung during of puberty.

The aim of this study is to determine the effects of a short-term nigella sativa supplementation on superoxide dismutase and malondialdehyde levels in response to a boat of aerobic exercise in male volleyball players.
13 mail volleyball player students of Tabriz University of Medical Sciences (aged 22±2 years, body fat 15±8% and VO2max= 45±7 ml/kg/min) participated in this study. At the beginning all subjects participated in an aerobic exercise protocol with 75% VO2max on the treadmill for 30 minutes and then received 43mg/kg/d nigella sativa powder for 21 days. After 21 days of supplementation period, the protocol was repeated. Blood samples were obtained before and after each protocol to determine malondialdehyde, superoxide dismutase and Lactate. Data were analyzed by ANOVA repeated measure and LSD tests using SPSS20 at α≤0.05.
The results showed that one bout aerobic exercise with increasing level of lactate values necessary to create the oxidative pressure and SOD values also has increased. Was also shown, short-term nigella sativa supplementation had no significant impact on the levels of base of Malone dialdehyde (P 0.05 >) But although supplementation had no effect on the SOD level in exercise response it before and after short-term nigella sativa supplementation (05/0 These data indicate that aerobic exercise can increase blood biomarkers of oxidative stress and supplementation with nigella sativa could not significantly attenuate exercise-induced oxidative stress in men
