This study was designed to investigate the effects of the progressive muscle relaxation on behavioral states and emotional reactions of adolescent athletes. The participants were 167 adolescent male soccer players aged between 12 and 18 who were junior or high school students in Seoul. Ninety-three of them were assigned to the experimental group, while seventy-four to the control group. The experimental group was treated by 10 sessions (20 min./session) of Jacobson's progressive muscle relaxation for two weeks, while the control group was not treated. The self and observer reported behavioral states, general stress by visual analogue scale, physical symptoms of stress, athletic stress, state anxiety, depression, self-esteem were measured before and after two weeks of the progressive muscle relaxation. The results were as follows ; 1. The self and observer reported behavioral states were significantly decreased in the experimental group compared with the control group. 2. The general stress and the gastrointestinal symptoms of stress were significantly decreased in the experimental group compared with the control group. No significant difference on athletic stress was found between the two groups. The depression and the state anxiety were significantly decreased in the experimental group compared with the control group. The self-esteem was significantly increased in the experimental group compared with the control group. 3. The influential factors on behavioral state of adolescent male athlete were depression and state anxiety. The accelerating factor on behavioral state change after the progressive muscle relaxation was state anxiety. These results are suggested that the progressive muscle relaxation could be effective in stabilizing behavioral state, decreasing general stress, gastrointestinal symptoms of stress, depression, state anxiety, in increasing self-esteem of adolescent male athletes. And the behavioral state change after the progressive muscle relaxation was influenced by state anxiety.

To improve abdominal muscles strengthening, double straight leg lowering (DSLL) has been widely used in physical therapy, fitness program, and athletic program. The purpose of this study was to investigate the effects of the lumbar stabilization maneuver with a pressure biofeedback unit on the muscle activity of rectus abdominis (RA), external oblique (EO), and internal oblique (IO) during DSLL. Fourteen healthy young men were recruited from university population. The electromyography (EMG) activity was recorded from the RA, EO, and IO of both sides. The normalized EMG activity was compared using a paired t-test. The study showed that EMG activity in the RA, EO, and IO was significantly higher during DSLL with lumbar stabilization (DSLL-LS) compared to performed DSLL (p<.05). These results suggest that DSLL-LS is recommended as an effective method for strengthening exercise for the abdominal muscles.

Dynamic visual acuity is used as an important factor to measure athletic performance in sports field. A study on visual acuity testing system using non-see head mounted display (NST-HMD) was conducted recently. However, the NST-HMD has a problem that the sense of space felt by the subject differs from the actual environment. This is because the view is blocked so that it is only implemented in a virtual space. This paper proposes a dynamic visual acuity testing system using optical see through head mounted display (OST-HMD). To do this, OST-HMD and NST-HMD comparative tests were conducted using existing K-D (King-Devick) charts. Experiments were performed on 30 subjects and their visual acuity was measured and analyzed by parametric statistics and one-sample T-test. The results of the study demonstrate the effectiveness of the proposed OST-HMD. This study is expected to use the visual inspection and training equipment of OST-HMD.

Purpose: The purpose of this study is to analyze factors affecting suicidal ideation of athletes in middle and high school. Methods: The data in this study came from the survey which conducted to 500 students of physical education high school athletes and elite athletes in general school from the beginning of December 2009 to the end of January 2010 in Seoul and Kyunggi. Finally 436 cases was used. The dependant variable is suicidal ideation in this study. And the independent variables are socio-demographic factors, exercise-related factors, school and family environments, stress and depression factor. The analysis method is logistic regression analysis. Finally 436 cases was used. Results: First, the rate of suicidal ideation of athletes in middle and high school was 28.9%. Second, there were significant differences between stress and sex, grades, athletic career, kind of sport, sport skill level, the average exercise time per day, family circumstances, life satisfaction, future expectations. Third, there were significant differences between depression and sex, academic achievements, the average exercise time per day, family circumstances, life satisfaction, future expectations. Fourth, there were significant differences between suicidal ideation and sport skill level, academic achievements, the average exercise time per day, family circumstances, life satisfaction, future expectations. Fifth, the higher level of stress and degree of depression, the more increased the risk of suicidal ideation. Conclusions: Considering the close relationship between suicidal ideation and suicidal attempt, to reduce the suicidal ideation of athletes in middle and high school it is necessary to adjust exercising time properly and to promote life satisfaction. Also to overcome depression and stress support system should be established and to promote self-efficacy cognition strength program should be introduced in the school. So athletes in middle and high school should have confidence and self-confidence on the future.

This study investigated the effects of personal (gender, school grade and causal attribution for success and failure) and environmental (mother's evaluation of their children and mother's efficacy) variables on children's perceived competence. The subjects were 595 fourth and sixth graders and their mothers selected from 3 elementary schools in Pusan. Children's perceived competence was studied under 3 categories : scholastic, social, and athletic competence. Data were analyzed by SAS/PC+ program. Internal attribution for the success had a positive influence on perceived competence while internal attribution for failure had a negative influence on perceived competence. Mother's evaluation of their children had a stronger influence on perceived competence than mother's efficacy. Mother's evaluation of their children was the most influential variable in all 3 categories of competence while secondary and tertiary variables varied by internal attribution for success or failure and by gender.
