The purpose of this study is to evaluate the physical fitness status and health promoting life styles of the workers. For the purpose, 108 workers who attended the exercise program in Inchon branch of KISCO were selected as the subjects. From Oct. 20th to Nov. 30th, in 1998, they were firstly assessed their physical fitness. The items include cardio-respiratory endurance, flexibility, muscular strength, muscular endurance, agility, power, balance, body composition, etc. Secondly, the health promoting life styles were asked by questionnaires about daily life and dietary habits. Both of them were evaluated by 5 or 3 levels as A(very good) to E(very poor) or A (good) to C(poor). Those data were analyzed percentile, mean, standard deviation by SAS program. Major findings are as follows ; 1. The health promoting life styles were generally good, but 43.5% of the subjects didn't exercise at all. Most of them(93.5%) thought about their physical fitness status as lower than average level. About half of them(48.1%) didn't drink alcohol, non smokers were 70.4% of them. But they had poor dietary habits(lower than average level : 79.6%), females were a little bit better than males. The aged group had the poor body compositions, 21.4% of females and 10.0% of males were obese. 2. Physical fitness status of the workers were assessed as two areas, one is health related, the other is physical function related area. In the health related area, females were better than males, in view of age, forties aged group had the highest scores of all items except cardio-respiratory endurance. Among 'A' and 'B' level, muscular endurance was showed most frequently, followed by muscular strength, flexibility, cardiorespiratory endurance. In physical function related status, balance was ranked highly in the portion of over 'B', followed by power, agility. In view of sex, males were better than females for all items except balance, and there were various figures in the status by age groups. 3. Comprehensive assessment scores were poor(under 'D' leves were most frequent), females were better than males, and teenage group had the worst scores. In ages of the physical fitness, generally they had 1 year under their real ages, and females were better than males. In view of age, forties aged group was ranked highly and teenagers had lowest scores.

The purpose of this study was to analyze the effect of a 12 week aerobic resistance training circuit program on the health-related fitness, blood lipids, and cortisol in obese postmenopausal women. The subjects for the study were twenty obese postmenopausal women composed of the exercise group (n=10) and "no exercise" control group (n=10). The aerobic resistance training circuit program was conducted for 70 minutes 3 times a week for 12 weeks, in which the aerobic exercise consisted of 5 items each composed of 5 sets of aerobic exercise at 50-70% HRmax intensity for 1 minute for a total of 25 minutes and the resistance exercise consisted of 8 items conducted for a total of 25 minutes at 40-60% intensity of 1RM). In the exercise group, the body weight and BMI significantly decreased and the 20m shuttle run, sit-ups and sitting trunk flexion significantly increased. In the exercise group, the TC, LDL-C, and TG significantly decreased. Also, it was noted that the HDL-C was slightly higher in the exercise group than in the control group, but the difference was not statistically significant. The cortisol levels of the exercise group and control group at baseline were similar. However, after the aerobic resistance training circuit program, the exercise group had a significantly higher cortisol level than the control group. Therefore, regular and continuous aerobic resistance training was effective in improving the body composition, blood lipids and health-related fitness.

Korea's golf fever is as good as the United States, Europe and Japan, which are called golf powers. The senior golf population over 55 years old has exceeded 2.5 million, and they are more interested in improving golf performance than participating in golf. So, this study aims to emphasize the importance of dynamic preparation exercise by identifying the effects of dynamic preparation exercise on golf physical strength and golf batting in order to suggest a way to help the elderly men's golf performance. The experimental group(n=13) and the control group(n=14) were divided into two groups and repeated measurements were conducted by two-way ANOVA with pre- and post-design. As a result of the analysis, the flexibility factor showed a positive effect on golf physical strength, and in golf batting, head speed, distance, and attack angle showed interaction effect, which led to the conclusion that dynamic preparation exercise helped the golf performance of the elderly male. Therefore, the continuous dynamic preparation exercise led to positive transition to head speed and attack angle due to the increase in the flexibility of the body, which led to the improvement of distance and the increase in performance level.

The purpose of this study is to analyze the effects of exercise program for prevention of falling on physical fitness, posture and fall prevention self-efficacy for elderly women. 30 females above the age of 65 were subjects for this study. Over an twelve week period, 14women in the experimental group performed exercise 2 times a week for 60 minutes per session. 16women in the control group didn't participate in the exercise program. The independent variable was a exercise program for prevention of falling. Dependent variables were physical fitness, posture and fall prevention self-efficacy. Prevention of falling exercise program is consisted of an elastic band using exercise and Korean dance movement exercise. Physical fitness consisted of grip strength, upper and lower body endurance, cardiovascular endurance, flexibility, balance, coordination. The posture was measured the static posture when standing, using a high-resolution camera, body style to automatically measure the distance and angle(M-zen, Korea). Posture was measured in both the coronal and sagittal plane via reference board. Fall prevention self-efficacy was measured via questionnaire using the Korea Falls Self-Efficacy Scale (FES-K). The physical fitness, posture and fall prevention self-efficacy were measured twice with pre and post exercise, and the difference between groups with Wilcox signed rank test, and the group-specific post verification was carried out with U-validated methods (Mann Whitney U test). Statistical significance level was verified by setting the p<.05. Lower body endurance, cardiovascular endurance, flexibility, balance and coordination significantly increased in the experimental group. The control group was no significant increase in physical fitness variables. shoulder slope angle, pelvic slope angle(coronal/sagittal), leg length difference, scapular inferior angle and left/right calcaneus angle significantly decreased in the experimental group. Both the experimental group and control group were no significant increase in fall prevention self efficacy. The prevention of falling exercise program for elderly women indicated the positive changes in physical fitness(except grip strength) and posture(except upper body slope). However, there are no significant differences of falling prevention self-efficacy between the both group. Thus, the prevention of falling exercise program for the elderly has been proved that it is highly efficient on improving physical fitness and posture proofreading. However, we still need to consider supplement exercise for grip strength and upper body slope.
