The purpose of this study was to compare the self-description of physical characteristics of athletic and non-athlete male students by self-concept and self-concept of physical fitness.

For this purpose, we selected 100 male high school students in the city of Chamestan from 12-15 years old using random sampling. After weighing the weight, height, body mass index, subjects were divided into four groups: athlete-obese (group 1), non-athlete obese (group 2), athlete non-obese (group 3) and non-athlete non-obese (group 4). All four groups completed PSDQ self-descriptive questionnaire they made the questionnaire was divided into two levels of physical self-concept and physical appearance self-concept, each separately measured. For analysis and comparison, one-way analysis of variance (ANOVA) was used to analyze and compare.

The results showed that non-athlete athlete students had better physical fitness and apparent ability than non-athletic athletes, non-athlete, non-athlete, and this difference was statistically significant. In addition, the results showed that self-concept of body fitness and body appearance of non-athletic and non-athletic subjects were not significantly different, and the difference between them was not statistically significant. In addition, non-athletic, non-obese, non-athlete with obesity, in terms of self-concept, had better physical fitness and self-concept, but also statistically significant.

Physical activity and exercise can have a significant positive effect on physical self-description (physical appearance, body fitness self-concept) of male students.

The aim of this study was to investigate the relationship between body image and physical fitness of girls with depression, anxiety and stress. The statistical population was all the students 13-15 years old, from secondary schools of Nour city in the 2020-2021 academic year. 100 students were selected by cluster sampling method. AAHPERD fitness test, participants' personal-social information questionnaire, Multidimensional Body-Self Relations Questionnaire and DASS 21, were used. Pearson correlation tests showed that there is a significant and inverse relationship between body image of girl students and their anxiety, depression and stress. There is also a significant and direct relationship between decreased body image satisfaction due to overweight and depression, anxiety and stress. In addition to physical problems, obesity also causes mental problems. Therefore, attention and treatment of mental problems in addition to physical problems of obesity is important. Levels of physical fitness are significantly associated with depression, anxiety and stress in adolescent girls.

Pumpkin (Cucurbita moschata) is one of the vegetables that has high nutritional value and bioactive compounds. The aim of this study was to compare the effect of hydroethanolic and aqueous solvents on the functional potential and to investigate the bioactive compounds of Pumpkin extract. For functional evaluation of extracts, the amount of ascorbic acid, total phenol and flavonoids, antioxidant capacity were performed by DPPH and FRAP methods and also the chemical compounds in the extracts were identified by GC/MS. The results showed highest levels of ascorbic acid, total phenol and flavonoids in the hydroethanolic extract were 98.66±13.29 mg/100g, 1.663±0.004 mg GA/100g and 0.381±0.01 mg QU/100g, respectively. Hydroethanolic extract showed the highest ability to inhibit DPPH radicals compared to aqueous extract in all prepared concentrations; so that hydroethanolic extract with a concentration of 800 μg/ml with 61.866% inhibition had the highest inhibitory properties. Detected chemical compounds in hydroethanolic and aqueous extracts using GC/MS were identified 16 and 7 chemical compounds, respectively, when the highest compound content in hydroethanolic extract equal to 34.86767% related to D-erythro-pentose, 2-deoxy and the aqueous extract was related to 5,2-dichlorophenol (74,2053%). The results of this study suggest the use of hydroethanolic solvent for higher extraction of bioactive compounds from pumpkin.

The aim of this study was to investigate the general health of active and inactive teachers in Chamestan. To this end, 248 working teachers in Chamestan, two public health questionnaires Goldberg and Hiller (GHQ) to measure the four subscales of physical health, anxiety and sleep disorders, social functions and depression, and Beck questionnaire to measure physical activity. Completed. The UM-Whitney test for comparing groups showed that active teachers in Chamestan compared to inactive teachers in Chamestan had higher general health, better physical health, less anxiety and sleep disorders, better social functioning, and lower levels of depression. (01 / p.). The general health and its sub-indicators of active teachers are higher than those of inactive teachers are. Physical activity as an important tool for maintaining the health of society can be used in the treatment and prevention of various physical diseases and equally in the control and treatment of mental problems such as depression, anxiety and sleep disorders.
