Purpose: Obesity is a complex disease that causes oxidative stress by disrupting fat metabolism. The aim of this study was to investigate the effect of ten weeks of swimming exercises with nigella sativa (Black Seed) supplementation on the plasma lipid profile of inactive obese women. Method: In this study, 40 inactive obese women with a body mass index (BMI) higher than 26, and an average age (29.06 ± 7.94 years), were voluntarily selected and randomly divided into four groups of 10 people. The control group, the training group, the training group - nigella sativa supplement and the nigella sativa group were divided. The control group had a normal diet and no training; the nigella sativa supplement group consumed 2 nigella sativa capsules of 1000 mg daily for 10 weeks; The swimming training group performed swimming exercises for 10 weeks and three sessions a week with an intensity of 60% of the maximum heart rate and the duration of each session was 75 minutes; the nigella sativa -training group also performed both the training and supplement protocols. At the end of the period, blood indicators of (low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride (TG) and total cholesterol. Total (TC)) and anthropometric variables were measured. Covariance analysis and paired t-test at a significance level of 0.05 were used for data analysis. Results: Investigations showed that there is no significant difference between the groups in the values of HDL-C, LDL-C, TG and TC (P>0.05). However, in the intra-group comparison, hockey results have a significant difference in HDL-C, LDL-C, TG and TC in the exercise and exercise +supplement and nigella sativa groups (P>0.05). Conclusion: It seems that taking two weeks of swimming exercises along with nigella sativa supplement improves some of the fat profile indicators and can probably be effective in improving the complications caused by obesity.

The present study seeks to compare life satisfaction, happiness and self-esteem of female athletes and non-athletes aged 20 to 65 years in Tabriz. The present study is a causal-comparative study. The statistical population of the present study was all female athletes and non-athletes in the age range of 20-65 years in Tabriz. From this statistical population, 349 female athletes and 135 non-athletes were selected as a sample using Morgan Table and cluster random sampling method. Cooper-Smith standard self-esteem, Satisfaction with Life Scale (SWLS) and Oxford Happiness (OHI) questionnaires were used in this study. The results of independent t-test, one-way analysis of variance and Friedman test showed that women athletes have higher life satisfaction, happiness and self-esteem than non-athletes. Also, with increasing duration of sports activities, women’s rate of happiness is also on the rise, and the first five years of exercise have had the greatest impact on women's self-esteem.
