The purpose of this study was to identify the effect of systematic mental skills training (MST) for a taekwondo gold medallist. Based on MST of other sports, this programme was designed for a single subject who competed in the Olympics. The Korean test of performance strategies, Sport Attributional Style in Korean Athletes, and a few sessions of interviews were applied to investigate the effect of MST. The pre and post-test mean scores of both the Korean test of performance strategies and Sport Attributional Style in Korean Athletes were compared. Interviews recorded the athlete’s psychological characteristics. Excluding the ‘activation’ variable, all of the psychological skills, e.g. self-talk (4.25–5), emotional control (3.75–4.5), automaticity (3.75–4.25), goal setting (4.5–5), imagery (4.25–5), negative thinking (3.25–4.75), anxiety management (4.5–5), and physical and mental condition (4.5–5) improved. MST is believed to have helped the athlete succeed.

Purpose The purpose of this study was to develop a Korean Life Skills Scale for Sports (KLSSS) that original version is the LSSS developed by Cronin and Allen (2017). Methods The subjects were 899 middle school and high school students. The measurement tool was used with LSSS. The validation of KLSSS followed a three-stage of validation procedure; substantive stage, structural stage, and external stage. The result is as follows. Results First, In the substantive stage, KLSSS consisted of 47 items with 8 factors. As a result of the item clarity test, it was confirmed that all the items were appropriate. Second, in the structural stage, KLSSS was explored and confirmed as 5 factors and 18 items. Third, in the external stage, KLSSS showed discrimination and convergent validity. Conclusions KLSSS is composed of 5 factors and 18 items. The factors are teamwork (TW), goal setting (GS), time management (TM), social skills (SS), and leadership (LD). This scale can be used to obtain information on life skills in school physical education or sports.

For this statistic, SPSS 12.0 for windows was used for technical statistic, two-way ANOVA, paired t-test, and independent t-test. The results were as follows; First, there were differences of change pattern in physical self-concept generally between Taekwondo participation group and non Taekwondo participation group.
