The present research examined the effects of the affective and cognitive benefits of exercise in Instagram on users' physical activity through two consecutive studies. The results of the first study showed that the designed content provided sufficient cognitive and affective benefits. Similarly, the second study found that after adjusting the basic PA level, the affective and cognitive groups had more PA than the control group, and the cognitive group had more than the control group. Consecutively, 45.75% of subjects who were inactive were turned into active after one week of being taught of the benefits of exercise, with 71.43% in the affective group and 28.57% in the cognitive group. In terms of gender, 84.12% were women and 15.78% were men. As a result, visual exposure to sports participation might have led to an increase in positive feelings among users, especially women, which may have led to increased PA levels. The results of this study are useful for health professionals who are trying to communicate information about the benefits of exercise to their target audience based on a combination of evidence, gender, and PA level.

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.

Purpose: Functional Movement Screening Test (FMS) is a tool that has the ability to determine a person's potential for the possibility of suffering from musculoskeletal abnormalities and sports injuries. FMS tests include seven functional movement tests that evaluate trunk, central strength and stability, neuromuscular coordination, asymmetry in movement, and flexibility. The purpose of this research was to determine the norm of the functional motor screening test in the male handball players of the Sepahan club in Isfahan. Method: The method of collecting information is cross-sectional and in terms of practical purpose. For this purpose, 30 male students aged 14-16 from Sepahan Handball Club of Isfahan were evaluated by performing 7 FMS tests. Findings: The norm of FMS test in 14-year-old students was 14.39±1.66, in 15-year-old students it was 15.85±1.47, and in 16-year-old students it was 15.29±1.21. Therefore, it can be stated that the FMS scores in these people are in a better condition compared to related studies in this age group. Also, the test scores separately showed that 75% of this population does not have enough stability in the central part of the body. Discussion and conclusion: In many sports activities, the movements of the upper and lower limbs need to have sufficient stability in the central area, if there is no stability in this area, energy transfer does not take place well. Since this age group is at the beginning of official sports competitions and considering that the clinical usefulness of FMS is limited by the lack of Norm index in Iran, sports medicine specialists and sports team coaches can evaluate the value of Norm scores to diagnose and identify people. at the risk of physical deformity and injury at different ages and plan bodybuilding and corrective exercises based on it
