Purpose The current study investigated the effects of exercise information using social network service(SNS) to identify changes of physical activity and psychological variables among inactive college students. Methods Inactive college students(30 experimental group, 30 control group) were voluntarily participated in the 12-weeks intervention. During this period, the experimental group received exercise information through SNS. And all study participants’ physical activity, stages of physical activity, self-efficacy, motivation, and perceived benefits and barriers were measured at the pre, mid and post intervention. Frequency analysis, chi-square test, 2-way ANOVA RM were conducted to analyze data obtained in the study. All procedures were performed by using SPSS 23.0. Results The exercise information intervention using SNS during 12 weeks had a positive effect on the stages of physical activity of inactive college students, and there were statistically significant differences. In addition, physical activity, perceived benefits and barriers, self-efficacy, motivation positively improved after the intervention, but there were no statistically significant differences between experimental and control group. Conclusions The present study suggests that psychological strategies using various SNS programs have positive effects for inactive college students to increase physical activity and its related psychological variables.
PURPOSE This study aimed to examine the effects of motion analysis and image training using self-modeling with visual cues on the skill performance, imagery, and sports confidence of adolescent female soccer players. METHODS The participants were elite soccer players from two girls’ high school soccer teams divided into an experimental group (D girls’ high school, n=16) and a control group (I girls’ high school, n=13). The experimental group underwent motion analysis and image training when performing penalty kicks, short kicks, and long kicks using self-modeling with visual cues, while the control group underwent training using self-modeling videos without visual cues. Before and after the training, the evaluation score was calculated according to kick performance, and the imagery and sports confidence factors were measured. For the statistical analysis of all collected data, descriptive statistics, the Friedman test, the Mann-Whitney U test, and two-way repeated-measures analysis of variance were used. RESULTS First, on the motion analysis using self-modeling with visual cues, the experimental group’s penalty kick and short kick scores were improved and differed significantly, but no significant change was noted in long kick score. Second, as a result of image training using self-modeling with visual cues, all visual, kinesthetic, mood, and controllability factors of the experimental group improved except for the auditory factor, and the interaction effect was confirmed. In addition, the stated sports confidence of the experimental group was improved and the interaction effect confirmed. CONCLUSIONS The analysis of kick motion using self-modeling with visual cues was effective for the penalty kicks and short kicks of adolescent female soccer players. Moreover, this study confirmed that the analysis of kick motion improved the visual, kinesthetic, mood, and controllability sub-factors of imagery and significantly affected the players’ stated sports confidence.
