The purpose of this study was to investigate effects of 12 weeks of regular exercise on physical fitness and health-related variables in iron industrial workers. Thirty eight untrained volunteers that they who have a adult disease risk factor. All subjects participated to combined exercise program (weight training: 1RM 50-70%, 12-20 repetitions, 3-5sets, 30sec rest between each set, endurance exercise: RPE 15±2, 25min). Physical fitness (back strength, sit and reach, sit-ups, 1000m) and health-related index(weight, blood pressure, blood glucose, total cholesterol, HDL-c, LDL-c, triglyceride(TG), body fat, muscle mass, BMI) were measured before and after of the combined exercise program. Basal fitness was significantly difference that sit ups(P<.01), Health related variables were positive effect on blood glucose(P<.01), HDL-c(P<.01), LDL-c(P<.01), TG(P<.01), BMI(p<.05), and muscle mass(P<.01) improved significantly in pre and post. These result indicated that the regular exercise program of 12 weeks positive effects on physical fitness and health-related variables.

The purpose of this study was to compare and analyze the difference on physique and physical fitness of the fifth and sixth grade elementary school students on regular exercise program during the semester through PAPS(physical activity promotion system) in Busan. The participants for this study were 1487 students, composed of 387 participated exercise program students and 1100 non-participated jogging program students. The measure of physique(height and weight) and physical fitness(body mass index: BMI, physical efficiency index: PEI, grip strength, trunk flexion, standing long jump, physical fitness level) were analyzed between exercise group and non-exercise group in elementary school students. The test data were analyzed in independent t-test, using the Statistical Package for SPSS version 17.0 for Windows. And the alpha level of p < .05 was set for all tests of significance. The result of this study were as follows; First, In physique, height and weight had significantly increased in the 5th grade boys, and weight had significanty increased in the 5th and 6th grade girls participated in exercise program. Secondly, In physical fitness, PEI and grip strength had significantly increased in the 6th grade boys and girls. Also, PEI, grip strength and standing long jump had significantly increased in the 5th grade boys, and PEI, grip strength, trunk flexion and standing long jump in the 5th grade girls. Physical fitness level had significantly decreased in the 5th grade boys and girls group.

이 연구는 10주간의 지체장애 대학생의 규칙적인 운동 참여가 신체적 자기개념 및 기초체력에 미치는 효과를 규명하고자 수행되었으며, 이를 토대로 지체장애 대학생의 바람직한 자아개념 형성과 생활체육 프로그램 개발 및 참여의 활성화를 위한 근거 자료를 제공하는데목적이 있다. 이 연구에 참여한 연구대상은 지체장애 2급 이상인 남자 대학생 8명(오른쪽 편마비 2명,왼쪽 편마비 2명, 하지마비 2명, 사지마비 2명)이었으며, 대상자 개개인의 장애특성을 고려하여 구성한 개별화 운동프로그램에 10주간 주당 3일 빈도로 참여하였다. 개별화 운동프로그램 참여 전후의 기초체력(근력, 체지방률, 안정시 심박수)과 신체적 자기개념을 각각 측정하였다. 수집된 자료는 대응표본 t 검정 및 Wilcoxon signed ranks test를 이용하여 변화를 분석하였으며, 그 결과는 다음과 같다. 첫째, 규칙적인 개별화 운동프로그램의 적용이근력에 유의한 효과를 나타내었다(p<.05). 둘째, 규칙적인 개별화 운동프로그램이 신체적자기개념의 하위요인 중 스포츠유능감, 건강, 그리고 신체적 자기개념 전체에서 유의한 효과를 발휘하였다(p<.05). 이와 같은 결과를 토대로 2급 이상의 지체장애인에 있어 규칙적인 신체활동의 수행이 유산소성 체력 요인의 향상보다는 근력의 향상에 더 큰 효과를 발휘하며 바람직한 자아개념의형성에도 긍정적으로 작용한다는 결론을 도출할 수 있었다.

In this study we examined that the effect of individualized regular exercise program on the alteration of physical fitness level and physical self-concept in physical disabilities. Total 8 volunteers were participated, and all participants have been classified as severe than second degrees of physical disability. All participants were performed individualized physical activity program for 10weeks(3days?wk-1). Exercise program included various stretching motions and warm-up, main exercise(either resistance weight or aerobic), and cool-down. Individual physical difficulties were considered when exercise programs were designed. The changes of fundamental physical fitness level (i.e., body composition, heart rate, and grasp strength) were measured, and physical self-description questionnaire(PSDQ), that included total 40 questions and 10sub-classified scales, was used to examine the change of physical self-concept. Whereas grasping power from both dominant and non-dominant hands was significantly increased(p<.05), body composition and resting heart rate were not significantly changed(p>.05) after performed 10weeks of regular exercise program. These results indicate that strengthening exercise program may exert better effects than aerobic exercise program in physical disabilities who have physically severe limitations for physical activities. PSDQ showed a significant improvement in sports competency scale and health related factors scale(p<.05), but it did not reveal statistical difference in any other sub-classified scales(p>.05). This result indicates that competency in routine life is possibly improved, and thus general health condition could be enhanced.
