The purpose of this study is to find out the role of inclination on the characteristics of coordination of walking movement. For the aim, a total of twelve female adults were selected and required to free-walk on a treadmill at normal speed(1.25m/sec). Four different angles were applied to the treadmill’s incline, i.e. 0%, 5%, 10% and -5%. Those female adults performed walking more than five time for each of the treadmill slope. The test was done using Vicon370 made by Oxford Metric Co. At least 3 sets of the test results, after excluding apparently abnormal figures, were standardized and analysed. In the analysis, the three-dimensional quantitative method was adopted. For the coordination factor analysis, correlation coefficient was checked to figure out coordination effect. From the above results, the following conclusion was drawn. 1. The effect of different inclination on coordination pattern was clearly revealed in flexion and extension of the sagittal plane, which showed large movements. 2. During walking, the degree of inclination affected the changing patterns of coordination in lower extremities.

This study conducted an aquatic rehabilitation exercise program with patients with hemiplegia after stroke for 12 weeks and examined its effects on daily living fitness, and blood lipid. The results are as follows. First, for a change in daily living fitness after aquatic exercise, the exercise group showed a significant difference in unaffected flexion(p<.001), unaffected extension(p<.001), affected flexion(p<.001), and affected extension(p<.001) of muscle strength and also showed a significant difference in muscle endurance(p<.001), flexibility(p<.001), and agility(p<.001). Second, for a change in blood lipid after aquatic exercise, the exercise group showed a significant difference in total cholesterol(p<.001), triglyceride(p<.001), high-density lipoprotein cholesterol(p<.001), and low-density lipoprotein cholesterol(p<.001). This study found that aquatic rehabilitation exercise had a positive effect on daily living fitness and blood lipid in patients with hemiplegia after stroke. However, the results of aquatic rehabilitation exercise programs for patients with hemiplegia after stroke greatly varied with exercise types, intensity, period, and time. Moreover, it is very restrictive to apply continuous exercise to stroke patients because of severe nerve paralysis and muscle atrophy. In this sense, it is necessary to conduct replication study through analysis of more factors and detailed clinical study with a large size group in order for longtime aquatic rehabilitation exercise using body buoyancy to be recommended for exercise and generalized as a rehabilitation method for stroke patients with severe paralysis. Therefore, further study should focus on the development of long-term exercise programs considering individual difference.

This study was divided into exercise group and control group for middle-aged women and participated in the Thera-Band Exercise program for 8 weeks, and compared before and after exercise to examine how body shape improvement and blood oxidative stress were affected. Statistical analysis was performed using the Window ver. SPSS 22.0 program. For the pre- and post-test of the two groups, the t-test method was used and the independent sample t-test was used to test the difference between the two groups. The statistical significance level of all results was .05. The results and conclusions are as follows. First, in the body shape improvement and the blood oxidative stress difference test, there was a statistically significant difference in the weight loss, body fat percentage and oxidative stress reduction in the exercise group (p<.001, p<.01). There was no statistical difference in the control group. Second, there was no statistically significant difference between pre - and post - body weight, body fat percentage, and blood oxidative stress in body shape improvement and blood oxidative stress difference test between two groups. As shown in the above results, middle-aged women participating in Thera-Band exercise showed positive results in improvement of body shape and blood oxidative stress. As the aging society progresses, middle aged women are prevented from aging fast, I think that it will be able to send a healthy middle age by controlling unnecessary oxidative stress in the human body. Subsequent studies suggest that antioxidant enzyme function may be added to the blood oxidative stress to prevent various diseases before they reach their old age.

The assumption in delayed menarche was that menarche is delayed in females who train regularly before and after onset due to excessive physical and mental stress. However, methodological problems involved with producing a precise explanation for delayed menarche have not yet been solved. Even when menarche is indeed delayed, the influence of sports training cannot be confirmed. Fujii verified delayed menarche in female athletes by examining the interval between age at the maximum peak velocity of height (MPV), a measure of maximum growth velocity during adolescence and age at menarche derived from the wavelet interpolation method (WIM). Based on the above finding, level of body stature was also classified from height in this study, with the second year of high school as the reference, against the constructed evaluation chart. Girls were classified by height as tall, average, or short, and an attempt was made to evaluate delayed menarche by height classification. Thus, risk analysis of delayed menarche in Koreans girls was done by applying the delayed menarche evaluation system for tall-short type.

The goal of this study is to evaluate the effects of backward walking exercise program on the balance and body composition of students with intellectual disabilities. We measured and analyzed the balance and body composition factors (body weight, body fat, muscle volume, skeletal muscle mass, body fat percentage) by applying backward walking exercise programs to students with intellectual disabilities for eight weeks, three times a week and fifty minutes a day, and the results of the analysis were as follows. Backward walking exercise program showed low, but had positive effects on the balance and body composition of students with intellectual disabilities. First, except for C student, student A, B and D showed better performance record of static balance and now all of four students are able to walk backward without any assistance on athletic park track, not on the indoor track and they have been improved to the level that they can even run. Second, although there are individual differences, the skeletal muscle mass of students with intellectual disabilities equally increased after eight weeks of practicing backward walking exercise programs. We concluded with these results that backward walking exercise programs have positive effects on body composition by increasing static balance time, reducing body weight, body fat and body fat percentage and increasing the skeletal muscle mass. It is also estimated that the program can help the students with intellectual disabilities to have right gait, improve health and prevent obesity.
