Research on the Influence of Media Internalized Pressure on College Students' Sports Participation-Chained Intermediary Analysis of Social Physique Anxiety and Weight Control Self-Efficacy.

Purpose: Discuss the relationship among college students' media internalized pressure, social physique anxiety, weight control self-efficacy, and sports participation in providing a reference for promoting college students to develop healthy and confident living habits. Methods: Take Southwest University in China as the object, select the subjects by stratified random sampling, and process the data with SPSS19.0 and AMOS21.0 statistical software. Results: (1) Media internalized pressure is positively correlated with social physique anxiety, weight control self-efficacy, and sports participation; social physique anxiety is significantly positively correlated with weight control self-efficacy and sports participation, and weight control self-efficacy is significantly positively correlated with sports participation; (2) media internalized pressure has a direct effect on sports participation (ES = 0.456), and social physique anxiety (ES = 0.136) and weight control self-efficacy (ES = 0.102) play significant mediating roles in the relationship between media internalized pressure and sports participation, respectively; the chained mediating force of social physique anxiety and weight control self-efficacy also reaches a significant level (ES = 0.027). Conclusion: Media internalized pressure can influence college students' sports participation through the direct path as well as indirect paths such as social physique anxiety, the intermediary effect of weight control self-efficacy, and chained intermediary effect of social physique anxiety-weight control self-efficacy, and social physique anxiety is another key factor affecting college students' sports participation except media internalized pressure.

The Relationship Between Physical Activity and Emotional Intelligence in College Students: The Mediating Role of Self-Efficacy.

BACKGROUND: College students are an inexhaustible driving force for social development, and college students with good physical and psychological qualities can better adapt to changes in the external environment. The purpose of this study was to explore the intrinsic relationship of physical activity and emotional intelligence among college students and to determine the primary role of self-efficacy in their relationships. METHODS: Eight hundred thirty-five college students from two comprehensive universities in Southwest China, whose average age was 20.13 ± 1.06 years old, were investigated using the Physical Activity Rating Scale (PARS-3), Chinese Emotional Intelligence Scale (EIS), General Self-Efficacy Scale (GSES), and other measuring tools. SPSS 22.0 software was used to analyze and process the data with Independent sample t-test, One-way ANOVA, Pearson correlation analysis, and regression analysis, and Amos 21.0 software was used to build the structural equation model. RESULTS: (1) In terms of physical activity amount, self-efficacy, and emotional intelligence, male college students scored higher than female students. Furthermore, college students in humanities and social sciences had lower self-efficacy. In contrast, senior students had the lowest levels of physical activity and self-efficacy, and there was no discipline or grade distribution difference in emotional intelligence. (2) Physical activity amount was positively correlated with emotional intelligence (r = 0.24, P < 0.001) and with self-efficacy (r = 0.26, P < 0.001), and self-efficacy was positively correlated with emotional intelligence in college students (r = 0.18, P < 0.001). (3) Self-efficacy played a partial mediating role between physical activity and emotional intelligence in college students (ES = 0.06). CONCLUSION: Regular physical activity can improve the self-efficacy and emotional intelligence of college students, and effectively promote the physical and mental development of students.

An Experimental Study of Step Test Index Combined With Heart Rate Variability in Estimating Maximum Oxygen Uptake in Women With Drug Use Disorder.

BACKGROUND: Maximal oxygen uptake (VO2max), a vital physiological indicator, has been widely used in many fields. In recent years, the measurement method of VO2max has been widely explored in various populations, but few studies have been conducted for women drug abusers. For the importance of VO2max in the formulation of aerobic exercise intensity for drug users, the present study estimated VO2max using the step test index combined with heart rate variability in women with drug use disorder. METHODS: Forty women methamphetamine (MA) users without cardiovascular disease and dyskinesia participated in a cardiopulmonary exercise test (CPX) and a 3-minute step test. Each of them performed a heart rate variability (HRV) monitoring test after the step test, and VO2max was estimated by step test index and HRV. RESULTS: (1) The step test index had a significant positive correlation with VO2max. The standard deviation of normal-to-normal interval (SDNN) had a significant positive correlation with VO2max and a significant positive correlation with the step test index; (2) the R-square values of the estimated VO2max by step test index and post-SDNN for overall MA users were 0.29 and 0.22, with an accuracy of 93.19 and 92.85%, respectively; (3) the R-square values of the estimated VO2max by step test index and post-SDNN in group I were 0.27 and 0.36, respectively, with an accuracy of 94.04 and 93.99%. The R-square value of the estimated VO2max by step test index in group II was 0.44, with an accuracy of 92.65%, however, post-SDNN cannot adequately estimate the VO2max in group II; and (4) there was no significant difference in VO2max obtained by CPX, step test index, or post-SDNN, regardless of overall or grouping variable analysis. CONCLUSION: The 3-minute step test combined with HRV can estimate the VO2max of women MA users to a certain extent, but the size and the coverage of the sample size should be further considered. In the future, more methods, such as machine learning or artificial neural networks, should be used.

Effect of Physical Activity on Drug Craving of Women With Substance Use Disorder in Compulsory Isolation: Mediating Effect of Internal Inhibition.

BACKGROUND: Women with substance use disorder has attracted widespread attention as a prominent social issue. According to reports, physical exercise can improve the internal inhibition, effectively reduce the substance user's drug graving, and improve withdrawal symptoms, however, the specific mechanism of internal inhibition should be further considered. This study was designed to determine the critical role of internal inhibition in the path of physical exertion affecting the drug cravings of women drug users. METHODS: By means of Physical Activity Rating Scale (PARS-3), internal Inhibition Scale and Drug Craving Scale, this study investigated the individuals with substance use disorder under rehabilitation in the women compulsory isolation rehabilitation center in Chongqing, China. RESULTS: (1) Women with traditional drug users had the strongest internal inhibition and new drug use disorder had the highest drug craving. The longer the duration of drug abuse, the lower the internal inhibition and the higher the drug craving. Women with moderate-intensity activity had the strongest internal inhibition and the lowest drug craving. (2) The physical activity intensity was negatively correlated with drug craving, positively correlated with intrinsic inhibition, and negatively correlated with drug craving. (3) Internal inhibition played a partial mediating effect between physical activity intensity and drug craving. CONCLUSION: Physical activity has a positive effect on inhibiting drug craving among drug addicts, while moderate-intensity activity seems to be more conducive to enhancing the internal inhibition of addicts, to improving their resistance to drugs, and thus more conducive to reducing drug craving.

The Influence of Sports Participation on Body Image, Self-Efficacy, and Self-Esteem in College Students.

OBJECTIVES: This study aimed to explore the relationship between body image, self-efficacy, self-esteem, and sports participation by gender, grade, and specialty and then to provide a reference for promoting participation in sports and physical activities in college students. METHODS: Using stratified random sampling, undergraduate students in western China were selected as participants. The data obtained in this study were processed by SPSS 19.0 and AMOS 21.0 statistical software. RESULTS: Body image was significantly positively correlated with self-efficacy, self-esteem, and sports participation. Self-efficacy was significantly positively correlated with self-esteem and sports participation. Self-esteem was significantly positively correlated with sports participation. Body image had a direct effect on sports participation, with an effect value of 0.124. Furthermore, the mediating effects of self-efficacy (0.079) and self-esteem (0.108) were significant in the relationship between body image and sports participation. Meanwhile, the chain mediating role of self-efficacy-self-esteem was also obvious (0.035). CONCLUSION: Body image, self-efficacy, and self-esteem had significant influence on sports participation in college students. At the same time, the mediating effect of self-efficacy, self-esteem, and self-efficacy-self-esteem on body image and sports participation were established, and self-esteem was the key factor to sports participation.
