Purposes: This study was to examine the effects of postpartum exercise on pressure of the pelvic muscle contraction, body composition and physical fitness of postpartum mothers. Method: A nonequivalent pre-test, post-test control group study was conducted. Fifty-two postpartum mothers(experimental group, 26; control group, 26) admitted to a postpartum ward in a Busan mother-baby clinic were recruited. Data was analyzed using mean, $x^2$-test, and t-test by SPSS 10.0. Result: Body fat mass(t=-3.196. p= .002), body fat rate (t=-3.831, p= .000), and fat distribution(t=-3.026, p= .004) of body composition increased significantly in the experimental group after the postpartum exercise as compared with the control group. After an 8 week exercise program, the pressure of the pelvic muscle contraction in the experimental group was significantly higher than in the control group(t=3.329, p=.002). In the change of physical fitness, grip strength of the hand, back muscle strength, and trunk flexion forward were not significantly changed, but trunk backward extension in the experimental group significantly increased(t=1.950, p=.050). Conclusion: Postpartum exercise affects pelvic muscle contraction, body composition, and physical fitness of the postpartum mother.

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.

Proper nutrient intakes and physical fitness focus one's attention on health promotion. This study was conducted to investigate nutrient intakes and physical fitness by BMI in middle school students. Health-related questionnaire, dietary intakes, food frequency questionnaire and physical fitness were studied. There were no significant differences in health-related questionnaire, food frequency questionnaire and physical fitness by BMI, but several nutrition intakes, preference of salty tastes and the proportion of iron deficiency of female students were significantly different by BMI. Although the female obese group (BMI 85 - 100 percentile) had decreased the proportion of iron deficiency and increased fish intake frequency than other groups, obese females did not show better physical fitmess than other groups. And the average Ca intake was below $75\%$ of Korean RDA in both male and female students. Significantly positive correlation was found between calorie intake and push-up of normal (BMI 15 - 84 percentile) male students (r = 0.29), also significantly negative correlation was found between protein intake and 50m dash of normal female students (r = 0.22). And significantly positive correlation was found between beans and bent knee sit-up of normal male students (r = 0.25), and significantly positive correlations were found between beans, meat, eggs, green & yellow vegetable and sit and reach (r = 0.20, r = 0.28, r = 0.21, r = 0.19) and significantly negative correlation was found between beans and long distance race of normal female students. Therefore, this study suggests that proper nutrition and non-obese states should be achieved for health promotion in middle school students.
