This study aimed to verify the effects of role modeling on adolescent athletes’ self-efficacy and flow state. The subjects were middle school and high school athletes registered with the Korean Sport & Olympic Committee. From the collected data, descriptive statistics, confirmatory factor analysis, correlation analysis, and structural equation model analysis were performed. To verify the mediating effects of self-efficacy in the relationship between modeling and flow state, structural equation modeling analysis was conducted. The direct effects of adolescent athlete modeling on flow state (β = 0.416, B = 0.244, p < 0.01) and self-efficacy (β = 0.479, B = 0.500, p < 0.01) were all significant, and the direct effects of self-efficacy on flow state (β = 0.404, B = 0.227, p < 0.01) were also significant. Furthermore, it was confirmed that the indirect effect of modeling on flow state (β = 0.194, B = 0.114, p < 0.01) was significant, and that the partial mediated effects of self-efficacy were significant. Thus, we confirmed that when adolescent athlete use modeling through a role model, their self-efficacy increased which in turn led to a positive effect on the ability to achieve a flow state.

Background: In attempts to hinder the spread of the Coronavirus disease 2019 (COVID-19), many countries have continued distancing, isolation, and quarantine measures, which has led to limited opportunity of physical activity. This study provides empirical support for a motivational process behind physical activity during the COVID-19 pandemic by testing the influence of psychosocial variables derived from the integrated model of self-determination theory (SDT) and the theory of planned behavior (TPB).Methods: A cross-sectional survey was conducted among Korean adults (N = 248). Participants completed the measures of SDT and TPB constructs modified to reflect their participation in physical activity during the COVID-19 pandemic. A sample size of 243 participants was employed, and the integrated model was tested using serial multiple mediation analysis to check the hypothesized relationships.Results: Findings indicated that in the COVID-19 context, the satisfaction of basic psychological needs positively predicts the level of self-determined motivations for physical activity, which is partially related to the level of social cognitive beliefs and intentions. The findings also demonstrated that attitude toward physical activity during COVID-19 was a major variable explaining the serial multiple relationships between the SDT and TPB constructs. The potential influence of demographics (gender, age, marital status, and past physical activity) was controlled as a covariate, and no significant effects were identified.Conclusion: The current study identified the psychosocial mechanisms of intention of South Koreans' physical activity during the COVID-19 pandemic, which could be used as an empirical basis for the development of interventions to maintain or strengthen physical activity in unprecedented situations.

The social cognitive theory model of physical activity is useful in understanding and promoting exercise. Self-regulation, as an element of the social cognitive theory model, is key to success in regular exercise participation. Existing research suggests that intrinsic motivation and positive emotion are associated with exercise participation and adherence. This study examined the relationships between self-regulation and exercise participation and adherence intention in university students when these two variables were controlled. Participants included 418 students enrolled in universities in Seoul (244 men, M age = 23.5 year, SD = 0.8; 174 women, M age = 22.8 year, SD = 1.0). The measures included the Self-Control Scale, exercise participation level, the Korea Exercise Adherence Intention Scale, the Korean Sport Participation Motivation scale, and the Korean Positive and Negative Affect Scale. Results showed that self-regulation ability was significantly associated with exercise participation level and adherence intention, when intrinsic motivation and positive emotion were controlled.

We analyzed participants’ feelings and arousal before, during, and after exercise as per whether they receive aromatherapy. Twenty university students who regularly took part in health exercises were selected through purposive sampling. Changes in feelings were measured through a 2D circumplex model and an in-depth interview. The effects on exercisers who received aromatherapy were more positive than for those who did not receive any treatment. Specifically, it induced positive feelings during exercise, reduced fatigue during exercise, and improved participants’ feelings during the recovery period. Aroma has a key influence on exercisers’ feelings, and it can positively influence exercise satisfaction and persistence.

Understanding the relationship between affect and exercise is helpful in predicting human behavior with respect to exercise participation. The goals of the present study were to investigate individual differences in affective response during and after exercise and to identify the role of intrinsic motivation in affective changes. 30 active male college students ( M age = 21.4yr.) who regularly participated in sports activities volunteered to answer a questionnaire measuring intrinsic motivation toward running activities and performed a 20-min. straight running protocol at heavy intensity (about 70% of VO₂max). Participants' affective responses were measured every 5 min. from the beginning of the run to 10 min. after completing the run. Latent curve model analysis indicated that individuals experienced different changes in affective state during exercise, moderated by intrinsic motivation. Higher intrinsic motivation was associated with more positive affect during exercise. There were no significant individual differences in the positive tendency of the participants' affective responses after exercise over time. Intrinsic motivation seems to facilitate positive feelings during exercise and encourages participation in exercise.

Social media has been an increasingly utilized communication tool, and it has gained popularity among adolescent athletes. Our aim here was to investigate whether a positive and honest self-presentation on social media increased adolescent athletes' self-esteem, and we examined the moderating effect of perceived responsiveness. After receiving informed consent of participants and their parents/legal guardians, we recruited 468 adolescent athletes/participants (244 males, 224 females; Mage = 15.39 years, SD = 1.61) through purposive sampling and engaged them in completing face-to-face or online self-report measures of their: (a) self-presentation on social media, (b) perceived responsiveness of others, and (c) Rosenberg self-esteem scales. Given the continuous nature of our moderating variable (i.e., perceived responsiveness), we conducted regression analysis using Hayes’s PROCESS macro in SPSS software. A positive self-presentation showed no significant relationship with self-esteem, except when the level of perceived responsiveness was high. Conversely, an honest self-presentation was positively related to higher self-esteem, and the relationship between honest self-presentation and self-esteem was moderated by perceived responsiveness. Our findings extend existing psychological theory into the online environment and have practical implications. These data highlight the link between social media self-presentation and self-esteem among adolescent athletes and illustrate the crucial role of perceived responsiveness in the social media context.
