Adolescent Athletes' Self-Presentations on Social Media and Their Self-Esteem as Moderated by Their Perceptions of Responsiveness by Others.

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.

Motivation and Intention Toward Physical Activity During the COVID-19 Pandemic: Perspectives From Integrated Model of Self-Determination and Planned Behavior Theories.

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 Effect of Modeling on Self-Efficacy and Flow State of Adolescent Athletes Through Role Models.

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 (ß = 0.416, B = 0.244, p < 0.01) and self-efficacy (ß = 0.479, B = 0.500, p < 0.01) were all significant, and the direct effects of self-efficacy on flow state (ß = 0.404, B = 0.227, p < 0.01) were also significant. Furthermore, it was confirmed that the indirect effect of modeling on flow state (ß = 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.

Can Aromatherapy Make People Feel Better Throughout Exercise?

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.

Basic psychological needs, exercise intention and sport commitment as predictors of recreational sport participants' exercise adherence.

Objective: This study aims to predict exercise adherence by examining from the standpoints of the exercise intention, the self-determination theory and the sport commitment model. Design and Main Outcome Measures: Data were collected from 391 Korean sports centre members (teens: 5.4%, twenties: 15.1%, thirties: 25.1%, forties: 28.1% and ≥ fifties: 26.3%). Questionnaires assessed the exercise intention and sport commitment as well as autonomy, competence and relatedness. Exercise adherence was measured by electronic attendance system. Data were analysed using reliability testing, descriptive statistics, correlation analysis, logistic regression analysis and binary classifier system. Results: All variables except for cognitive commitment had significant predictive power for 3-month exercise adherence. In contrast, only basic psychological needs were found to have significant predictive power for 6-month exercise adherence. Further, autonomy (OR = 4.58) showing the strongest predictive power (classification accuracy = 86.4%). Conclusion: These findings imply that 'basic psychological needs' plays a more key role than 'exercise intention' in predicting exercise adherence. This study has implications that need to focus not only on enjoyment or competition but also on the autonomy, relatedness and competence pertaining to the basic psychological needs and to work to satisfy those needs and maintain motivation to continue regular exercise.

Associations Between Self-Regulation, Exercise Participation, and Adherence Intention Among Korean University Students.

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.

Investigation of the Structural Relationships Between Social Support, Self-Compassion, and Subjective Well-Being in Korean Elite Student Athletes.

The study examined whether self-compassion mediates the relationship between social support and subjective well-being, as perceived by athletes. It also investigated the structural relationships between these variables. Participants were 333 athletes attending high school or university. Structural equation analysis showed that self-compassion partially mediated the relationship between social support and subjective well-being. To test the stability of the model, a multiple group analysis was performed according to sex of participant and school level, and this demonstrated that the model had similar fit to the data regardless of group. The confirmation that self-compassion plays an intermediary role in the relationship between social support and subjective well-being demonstrates that self-compassionate attitudes can be fostered by social support, and that, in turn, has a positive effect on an individual's subjective well-being.

Team Commitment as a Mediator Between Self-Esteem and Team Climate as Perceived by Korean Youth Soccer Players.

This study examined whether team commitment mediates the relationship between self-esteem and perceived team climate in Korean youth soccer players. A total of 366 youth soccer players from the Korea football association participated in this study. Self-esteem and team commitment were found to significantly and positively affect perceived team climate; team commitment more strongly affected perceived team climate. Regarding structural relationships, self-esteem's direct effect on perceived team climate was not significant; however, self-esteem's indirect effect through team commitment was significant. Team commitment therefore mediated the relationship between self-esteem and perceived team climate. Metric invariance was supported for groups categorized by grade and key player, confirming that the model could be applied to various groups.

DEVELOPING AND INSTRUCTING PRE-PERFORMANCE ROUTINES FOR TENPIN BOWLING COMPETITIONS (1).

This preliminary study developed pre-performance routines for tenpin bowlers and instructed them. To develop the routine, the situations before throwing the ball were divided into four phases; participants were examined through interviews and observations. This study used an A-B design; the A stage included the development of the routines for 3 wk., while the B stage included the instruction and two evaluations of the routine consistency. Practice was implemented for 4 hr. per day for 9 wk. The participants noted they understood the developed routine easily and experienced an atmosphere similar to that of a competition during training through the routines. They found it difficult to practice the relaxation phase, but emphasized that the relaxation phase was helpful. Consistent routines were associated with an improved mental state and performance in a competition. This study suggests that pre-performance routines stabilize the mental state of the athletes, apparently giving them a competitive advantage.

Empirical links between instruction with teaching tools and the hierarchical model of intrinsic and extrinsic motivation in a Korean college tennis class.

The objective of this study was to demonstrate the sequential process (i.e., social factors→mediators→motivation→consequences) underlying the Hierarchical Model of Intrinsic and Extrinsic Motivation at the contextual level in instruction using three teaching tools, modified balls, a high net, and colored balls and cones in a college-level tennis class in South Korea. 126 students enrolled in a 15-week tennis class participated in the study. The results indicate that the three teaching tools positively affected students' perceived competence, with perceived competence's beta on intrinsic motivation equal to 0.45. Intrinsic motivation was found to reduce negative affect further by -0.33, thereby demonstrating the sequential process of the Hierarchical Model of Intrinsic and Extrinsic Motivation.

Parental attachment as a mediator between parental social support and self-esteem as perceived by Korean sports middle and high school athletes.

This study examined whether parental attachment mediates the relationship between parental social support and self-esteem in Korean middle and high school athletes. 591 sports athletes attending middle and high schools that specialize in sport volunteered. Parental social support and parental attachment had a significant positive effect on self-esteem; parental attachment had a greater effect on self-esteem. In the structural relationship, direct effects of parental social support on self-esteem were weak, but indirect effects through parental attachment were strong. Therefore, parental attachment complementally mediated the relationship between parental social support and self-esteem. Metric invariance was supported for groups categorized by sex, region, and school level, confirming that the model could be applied to various groups.

Effect of intrinsic motivation on affective responses during and after exercise: latent curve model analysis.

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 = 21.4 yr.) 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.
