Introduction. Today, the poor movement that has been created as a result of tremendous improvements in technology and mechanization of life and different jobs affects lifestyle in human societies. These very serious changes have had profound effects on human relationships at different levels of family and relationships with friends (1). If we look at human's physical construction, we will realize that human need naturally different kinds of physical activities for his/her entire development and evolution and the lack of adequate mobility and the lack

of proper physical activities will disrupt different body systems. This great development in terms of health and well-being is one of the most important problems of today's human (1). This is very important for students, especially for students who are studying in a Master's degree. Students should have a physical and mental health due to their role in social, cultural, and economic structures and their preparation to participate in social activities (2). According to the World Health Organization (WHO), a person who does not have mental health is not

107

considered a healthy person. This message is also approved by Pan American Health Organization and World Federation of Mental Health (3). The mean of mental health is human's specific dimensions health such as intelligence, mind, and thought (4). Mental health is one of the factors that can be effective in the dynamics and development of a community. Research evidence show some environmental controversies that affect students' mental health such as the desire for different social entertainments against willingness to study, the desire for physical superiority against organ limitations, the need to the lessons development against the feel of incompetence, the fear of personality expression against the desire for self-esteem, and job selection (6). According to researchers' idea who has mental health is a person that is distant from anxiety and disability symptoms and she/he can establish a constructive relationship with others, and is able to cope with life stresses (6, 7). On the other hand, conducted studies in the field of psychology and exercise have shown that exercise and physical activities are one of the effective methods for the prevention and treatment of mental illnesses (7). Scientific evidences have shown that the participation in physical activities and the increasing of cardiovascular fitness are considered as an important factor in the improvement of mental health and mood (8). Nine factors are important in the creation of happiness and mental health that the participation in physical activities and exercise is one of the most important factors (9). Bakhshalipour, et al., (2017) studied psychological and physical indexes in women that they concluded that aerobic activities and trainings had many benefits for behavior and mood. Also, they stated that physical activities s were associated with the reduction of stress, tension, and the increasing of self-esteem (8). Wang, et al., (2004) expressed in their study that physical activity can play a role in the maintaining of securing mental health (10). The results of their study showed that exercise played an important role in the change of the

positive mood, self-satisfaction, sense of competence and efficiency that are components of individuals' mental health (10). Conducted Studies by Ainsworth, et al. (2005) showed that physical activity and exercise were effective on the promotion of mental health, the reduction of depression, and the increasing of well-being, mental and social health, self-esteem, and self-discovery (4). On the other hand, there is a strong relationship between sleep quality and mental health. Also, the use of exercise is usually a non-drug strategy that can have beneficial effects on individuals sleep (26). Studies have shown that the use of physical activity is one of the most effective daily behaviors in the relationship with sleep quality and mental health (27, 28, 29). This study has compared male and female athlete and non-athlete students' mental health, since many researchers have emphasized the role of physical activity and exercise as an instrument for the prevention of diseases and mental disorders and due to the existence of significant differences in men and women's physiological characteristics. The study in this field is important that exercise, gender, and marital status may have different effects on students' mental health. According to the findings of this study and differences of effectiveness in students due to studied different factors, we hope that can provide more effective and coherent programs for more participation in sports activities of different groups with an attention to these differences to improve students' dimensions of mental health and the reduction of mental and psychological stresses in addition to the improvement of their physical abilities with the participation in sports activities.

purpose of this study was to examine the effect of exercise on mental health in physical dimensions, anxiety, sleep disorder, social function, and depression in athlete and non-athlete students. The results of this study in the comparison of mental health mean in male and female athlete students and in female athlete and non-athlete showed that female athlete students had better performance in social function than male athlete and female non-athlete students. Fax and Matius have stated about the explanation of this result that

female athletes who participate in a training program benefit physically and socially and they enjoy sports groups and new friendships (15). These interactions help to eliminate feelings and distractions and non-athlete women are deprived of the opportunity that physical activities provide for them (15). Also, female athlete students' high social function than athlete male students may be due to men and women's different physiological characteristics including hormonal secretion and body composition (15) that those can affect their physiological

and social characteristics. This result is consistent with the results of Nasri and Vaez Mousavi's (2006) study. They studied sports coaches' mental health and concluded that female coaches' mental health was higher than male coaches (16). Alizadehasli (2003) found different results (17). He compared general health in athlete students that results showed that there was no significant relationship between gender and social dysfunction (17). The importance of this issue is that physical education and sports programs can resolve some of these social needs in participants. The results of Tucker's study showed that physical fitness reduced significantly the risk of mental disorders in men and women (8). The results of this study is consistent with the results of Bakhshalipour, et al's (2017) study that they examined the effect of aerobic training on non-athlete postmenopausal women's mental health (5). On the other hand, the difference in mean of mental health in the comparison of male and female athlete and non-athlete students did not show a significant difference in any of the subscales, but it was significant in all subscales with the comparison of male athlete and non-athlete students. So that male athlete students' mental health had better condition than the male non-athlete students. This result is consistent with the results of Khalaji, et al,'s (2007) study (14). They stated that male athlete students who participate regularly in physical activities such as walking, jogging, swimming, aerobics, or playing in sports teams can be able to do boring tasks in a longer period than inactive male students that this can be due to adaptive responses in a body as a result of regular exercise (14). There is a lot of evidence about the benefits of regular physical activity for general health (17, 27, 28). Studies show that intense and regular exercise is associated with less stress and anxiety. Also, people who participate in fitness and exercise programs report that their attitudes and efficiency are better at work, for example, they make less mistakes (20). It seems that exercise can play an important role in students' physical and

mental health due to all subjects are students who study at master's level and they do many research works, and modern life conditions that have physical abnormalities such as back pain, joint damage, and diseases such as obesity and cardiovascular diseases. Therefore, the increasing of motivation through culture and the promotion of general knowledge about the benefits of physical activity can be considered as one of the options for the improvement of student sport. A program that may not have been seriously considered so far. The other result of this study was that there was a significant difference between married and single students in terms of mental health indexes (P<0.05), so that married students had better status than single students in mental health, social function, depression, and somatic symptoms subscales. One of the points that can be emphasized in the explanation of this conclusion is paying attention to the role of marriage in the supply of social support. The benefit of this support enables students to solve their problems more precise and more accurate and it will increase the happiness in students' life. Sarafino (2002) believes that social support from friends, family, and others leads to the reduction of mental stresses in people and it affects their mental health (21). Hosseini and Hosseinchari (2004) compared some indexes of mental health in single and married students of Shiraz University (22). They concluded that married students' total score of mental health (45.18) was lower than single students' total score of mental health (23.65). Also, married students' score in all subscales is lower than that single students' score that it indicates married students had higher mental health than single students (22). This result is consistent with the results of

Lynch (1990); Berkman (1995); Zahrakar (2002); and Bakhshalipour, et al,'s (2016) study (23, 24, 25, 28).
