RESUMEN
Purpose: This paper aims to explore the relationship between body image, self-efficacy, self-esteem, and weight-loss intention among college students, offering insights to promote healthy and confident lifestyle habits. Methods: Undergraduate students from western China were selected using a stratified random sampling method. Data were analyzed using SPSS 19.0 and AMOS 21.0 statistical software. Results: (1) Body image showed a significantly positive correlation with self-efficacy and self-esteem but a negative correlation with weight-loss intention. Self-efficacy exhibited a significantly positive correlation with self-esteem and a negative correlation with weight-loss intention, while self-esteem was significantly negatively correlated with weight-loss intention. (2) Body image directly impacted weight-loss intention [Effect Size (ES) = -0.120]. Self-efficacy (ES = -0.069) and self-esteem (ES = -0.119) played significant mediating roles between body image and weight-loss intention, respectively. (3) The chained intermediary role of self-efficacy and self-esteem also reached significance (ES = -0.038). Conclusion: Body image conducts effect on the degree of weight-loss intention among college students through direct ways or indirect ways such as the intermediary role of self-efficacy and self-esteem, and also the chained intermediary role of self-efficacy and self-esteem. In addition, self-esteem is another key factors affecting college students' weight-loss intention.
RESUMEN
Purposes: This paper aims to discuss the relationship between college students' sports participation, school bullying, emotional intelligence and self-esteem. At the same time, it explores the intrinsic mechanisms of school bullying, in order to provide a reference for reducing bullying phenomenon among college students, and pave the way for college students to lead happy, healthy and confident lives. Methods: A total of 1,317 students (725 male students, 592 female students, 21.31 ± 3.28 years old) from four universities in Southwest China were selected as subjects for this survey. They were selected by stratified random sampling, and the data needed was obtained using a structured questionnaire. The data was subsequently processed with statistical software SPSS19.0 and AMOS21.0. Results: (1) Sports participation has a significant and positive correlation with emotional intelligence and self-esteem, likewise, it has a significant negative correlation with school bullying. Emotional intelligence has a marked positive correlation with self-esteem, at the same time it has a significant negative correlation with school bullying. In addition, self-esteem is strongly negative correlated with school bullying. (2) Sports participation has a direct effect on school bullying (ES = -0.271). Emotional intelligence (ES = -0.144) and self-esteem (ES = -0.065) also play a significant mediating role between sports participation and school bullying, and the chain mediating force of emotional intelligence-self-esteem also reaches a significant level (ES = -0.016). Conclusion: Sports participation affects school bullying among college students not only directly but also indirectly, such as through emotional intelligence, the mediating role of self-esteem, and the chain mediating role of emotional intelligence to self-esteem. Apart from sports participation, emotional intelligence is another key factor that affects college students' school bullying. Therefore, while attaching great importance to college students' sport participation, schools should also provide courses aimed at developing students' emotional intelligence.
RESUMEN
@#Objective To explore the biomechanics of different methods of taping on knee during sudden stop action, to prevent knee from joint injury. Methods From March to May, 2017, Eight male college students without lower extremity disorders participated in this study. Their relevant biomechanical parameters were collected when sudden stopping with traditional taping, kinesio taping or no taping of knee, using kinematics, kinetics and electromyogram (EMG). Results Peak horizontal force (F = 3.131, P < 0.01) and horizontal loading rate (F = 2.912, P < 0.05) were the largest, center of pressure moved rearward the most (F = 4.291, P < 0.01), and time of peak horizontal force appearance was the latest (F = 5.144, P < 0.001) with no taping. When peak horizontal force appeared, the flex of knee was the most with no taping (F = 8.141, P < 0.01). The angle of of knee changed the most with kinesio taping during landing (F = 5.491, P < 0.05), while the EMG of rectus femoris and gastrocnemius was the most with no taping (F > 5.322, P < 0.01). The active reset error on 45° and 60° of joint angle was the least with traditional taping (F > 5.631, P < 0.001). Conclusion Traditional and kinesio taping can restrict the forward movement of anterior cruciate ligament, while the kinesio taping is more effective on the maximal knee joint flex, the traditional taping works well for supporting knee, but limiting the range of movement.
