The purpose of this study was to analyze factors associated with continued participation intention. A total of 484 women in aerobic programs participated in this study voluntarily. Each participant completed a survey packet including demographic, participation motivation, leader’s image, participation satisfaction, continued participation intention questionnaires. The main finding in this study were as follows: Based on the results from t or F test, demographic variables(marriage status and age), and program characteristics variables are significantly associated with continued participation intention. Stepwise multiple regression analysis shows that practice times per week is most significant predictor among demographic and program related variables while condition/achievement, leader’s ability, and psychological satisfaction are the key predictors among participation motivation, leader’s image, leisure satisfaction variables. Also, stepwise multiple regression analysis using all independent variables shows that 6 variables(condition, physical fitness, practice times per week, relaxation satisfaction, leader’s ability, skill development) are significant predictors for continued participation intention. These results indicate that aerobic programs could be activated by means of leisure activities by analyzing the factors which influence continued participation intention, even though the predictors associated with the intention could be complicated. Leaders and participants in aerobic programs should be aware of the factors to increase continued participation intention so that drop-out rates of participants in aerobic programs could be reduced.

The purpose of this study was to examine the effects of 8-week boxing aerobic dance on leisure satisfaction and life satisfaction among adult women. A total of 74 women between 30s and 40s participated voluntarily in this study; 39 were in experimental group. All participants completed the survey packet including demographic questionnaire, leisure satisfaction scale(LSS), and satisfaction with life scale(SWLS) before and after 8-week boxing aerobic program. Participants in the experimental group were exposed to boxing aerobic dance for 8 weeks(e.g., 5 times/week, 50 min/day). The main findings in this study are as follows: (a) participants in the experimental group reported higher leisure satisfaction and life satisfaction compared with control group, (b) there were statistically significant correlation between subscales of leisure satisfaction and life satisfaction, and (c) the predictors explaining life satisfaction were psychological leisure satisfaction and family income. These findings in this study indicate that boxing aerobic dance is an appropriate leisure exercise program for adult women to increase their leisure satisfaction and life satisfaction. However, this study was first study to examine the effects of boxing aerobic dance. Ongoing research should be needed to better understand boxing aerobic dance on leisure satisfaction and life satisfaction.

The study has been conducted to compare isokinetic muscle strength among elite high school athletes in short-distance, long-distance, jumping and throwing. 44 athletes(11 athletes in each group) participated in this study voluntarily. Cybex770(cybex Norm™ test & Rehabilitation) isokinetic dynamometer was used to measure extension and flexion muscle strength of thign and ankle for each athlete. One-way ANOVA in the SPSS Ver. 19.0 statistical program was applied to compare the means of isokinetic muscle strength in left/right thigh and ankles among the groups. Main findings in this study were as follows. There were significant differences in left/right thigh extension muscle strength and flexion muscle strength among the groups. Also differences were found in thigh muscle power in among the groups. However, no differences was found in thigh muscle endurance among the groups, in muscle strength of ankle, there were statistically significant differences in left/right extension and flexion muscle strength among the groups. Same results were found in the muscle power and muscle endurance in ankle among the groups. This results indicate that athletes in short-distance running are superior in muscle strength to athletes in other types of sports. Athletes in throwing events have more muscle power and muscle endurance than other athlete groups. In ankle, athletes in short-distance and throwing have superior muscle strength and muscle endurance than other groups. Ongoing research is needed to better understand isokinetic muscle strength of various position in various sports to develop appropriate muscle strength for better results during competition and also to provide coaches and athletes for their training program and recruiting.

The purpose of this study was to analysis the effects of 15-week special physical education introductory class to find out the differentiation in attitude toward people with disabilities among college students in kinesiology major or minor. A total of 54 students including 30 male and 24 female participated in this study volunteerly. Each participant completed a survey packet including demographic questions and DFS(Disability Factor Scale) before class starts and after 15-week class. The DFS consists of 6 sub-scale with 37 questions including unconditional refusal(7 questions), distorted identification(5 questions), inferred emotional factor(7 questions), limitation of other function not damaged(6 questions), refusal of friendship(6 questions), and tension when contact with people with disabilities(6 questions). Main findings in this study were as follows: Based on the results from paired t-test, each the mean of 6-subscale of the DFS in the pre/post class were 2.65±.58/3.31±.37, 2.54±.51/3.46±.46, 2.47±.40/3.12±.41, 2.61±.46/3.31±.37, 2.84±.47/3.61±.39, and 2.69±.36/ 3.26±.30. All the means of sub-scales were significantly increased after the class. Also, there was statistically significant differentiation in the gran mean of DFS. These results indicate that special physical education introductory class could change college students’ attitude toward people with disabilities. This study could be a reference for the future study related to attitude with people with disabilities. 이 연구의 목적은 특수체육론 수업을 수강한 체육관련 학과 대학생들의 장애인에 대한 태도변화를 알아보기 위함이다. 총 54명의 학생들이 참여하였으며, 15주의 학기 수업 전·후 장애태도 검사지를 이용하여 조사를 하였다. 장애태도 검사지는 총 37문항, 6개의 하부요인(장애인에 대한 무조건적인 거부 7문항, 장애에 대한 왜곡된 동일시 5문항, 추론된 정서요인 7문항, 손상을 입지 않은 타 기능의 제한 6문항, 장애인에 대한 친교거부 6문항, 그리고 장애인과 접촉시 긴장 6문항)으로 구성되어져 있다. 특수체육론 수업 전·후 검사를 대응표본 t-검증을통하여 아래와 같은 결과를 얻었다. 장애태도검사 하부변인의 평균변화는 통계적으로 유의한 것으로 나타났다. 장애태도 검사지 전체의 사전·사후 평균 비교에서도 통계적으로 유의한 증가가 있는 것으로 나타났다. 특수체육론 수업을 통하여 체육 관련학과 대학생들의 장애인에 대한 태도 변화를 가져오게 하였다. 이러한 결과는 수업을 통하여 장애인에 대한 이해를 높일 수 있었고, 장애인들이 운동과 스포츠를 통하여 사회와 화합하려는 노력을 학습해 봄으로서 장애인들에 대한 태도를 긍정적으로 바꿀 수 있었던 것으로 설명할 수 있다. 특수체육론과 같은 수업을 대학이라는 교육 환경 뿐 만 아니라 다양한 학습환경에서 적용되어야 할 것이다.

The purpose of this study was to investigate the effects of blood flow restriction therapy on peak torque and work per repetition of thigh muscle. Twelve healthy male college students free of knee problems were enrolled in this study voluntarily. Muscle strength(60deg/sec of knee extension and flexion) of each participant was assessed by the isokinetic dynamometer under three conditions: (1) without blood flow restriction; (2) blood flow restriction of 100mmHg; (3) blood flow restriction of 200mmHg. The results were as follows. There were significant differences in means of peak torque of knee extension and flexion in the all comparisons(0mmHg vs 100mmHg, 100mmHg vs 200minHg, and 0mmHg vs 200mmHg). However, no significant were found in the comparisons of the work per repetition both in extension and flexion. The results indicate that blood flow restriction could help increase muscle strength.
