This study analyzed in depth the students' health fitness trend characteristics based on the per generation characteristics longitudinal grade level document that was produced by collecting heath fitness measurements of students from all over the country for the purpose of exploring the appropriate wellness management plan. The following conclusion was derived through the collected materials and results according to the research purpose and method. First, it was determined that muscular endurance trends for both boys and girls in their elementary school period were similar for the current generation and the previous one, but as they went through their middle school period their muscular endurance development levels were found to be reduced compared with the previous generation students. Second, there was no difference in the cardiorespiratory endurance trends between the current and the previous generation students, unlike all other physical factors. Third, the boys displayed deteriorated reflex development during their growth period compared with their previous generation counterparts. On the other hand, girls displayed mostly stagnant development once they reached 8th grade level within their generation.

Treatment for breast cancer produces side effects that diminish functional capacity and quality of life (QOL) among survivors. Tai Chi is a moderate form of exercise that may improve functional capacity, physical activity and oxidative stress. The purpose of this study was to evaluate the effects of regular Tai Chi exercise on malondialdehyde (MDA), SOD and physical fitness (muscle strength, flexibility, flexion, extension, adduction, and abduction). Forty obese women were recruited from a public health center and divided into control (CON: n=20) and trained (EXP: n=20) groups. The Tai Chi exercise group participated in a 12-week (4 times/week) training program. Data were analyzed with T-test. MDA, SOD and physical fitness (muscle strength, flexibility, flexion, extension, adduction, and abduction) were evaluated before and after the Tai Chi program in both groups. There were significant improvements in shoulder flexibility, flexion, extension, abduction, and adduction. However, there was no improvement in muscle strength. There were also significant improvements in MDA and SOD. Based on these results, Tai Chi exercise has been shown to stimulate endogenous antioxidant enzymes and reduce oxidative damage markers. and also be effective in improving physical fitness and QOL. Further study is needed in this area.

Purpose: The purpose of this study was to compare the effects of an exercise program on physical fitness, obesity indices, and blood lipids in cases of non-obese and obese women. Method: Data was collected from May, 2006 to November, 2006 in a public health center. All Subjects(37 women) participated in an exercise program that consisted of Latin dance, muscular strength training, and dumbbell exercises. Thirty-seven women were divided into two groups(16 non-obese women and 21 obese women) by %body fat. After 8 weeks, the effects of treatment were compared between pre-test and post-test in each group. Results: Physical fitness(abdominal muscle strength, muscle endurance, flexibility, agility, balance) was significantly different between the pre-test and post-test in the non-obese and obese group. Obesity indices(body weight, BMI) was significantly different in obese women after the 8-week exercise program. There was no decrease of blood lipids in either group. Conclusion: These findings indicate that an exercise program could be an effective nursing intervention to increase physical fitness in non-obese and obese women and to decrease obesity indices(body weight, BMI) in obese women.

Purpose: This study was performed to identify the health status, healthy behavior, and health promotion program needs of day time and shift time industrial male workers at an workplace. Method: Relevant data were collected from June 20 to August 18, 2005. Questionaries were distributed to all subjects along with their medical records of 2005 and 151 sets of responses were used for the analysis. Collected data were analyzed using SPSS WIN 10.0. Result: 1. Health Status - day time and shift-time workers had significant differences in obesity ($x^2=8.38$, p<.01) and blood pressure ($x^2=-2.17$, p<.05). 2. Healthy Habits - Full-time and part-time workers had significant differences in regular meals (63.83, p<.01), preferred foods ($x^2=7.10$, p<.05), and sleep time (t=-3.55, p<.01). They also had significant differences in exercising ($x^2=13.11$, p<.01), exercising time (minutes) (t=-2.25, p<.01), and use of fitness centers ($x^2=7.02$, p<.05). 3. They also had significant differences in their needs of health programs ($x^2=8.66$, p<.01). Conclusion: This study revealed that day time and shift-time workers had differences in obesity and blood pressure, as well as differences in eating sleeping, and exercising patterns. Both groups needed 'fitness programs' more than any other types of health programs and picked 'weight loss' and 'stress control' programs for other options. Industrial nurses should be able to create appropriate health programs for each group based on the above results and induce the workers' active participation.
