The purpose of this study was to find the effects of the lumbar stabilizing exercise on the isometric lumbar extension strength and the range of motion of lumbar extension. 16 healthy subjects were recruited (9 males, 7 females, mean age 25${\pm}$3.2). They performed 5 types of exercises 5 times per week for 4 weeks. We evaluated isometric trunk extension strength (0, 12, 24, 36, 48, 60, $72^{\circ}$) by MedX(Ocala, FL) and measured range of motion of lumbar extension. All measurements were measured at pre-exercise and 4 weeks post-exercise. The results of this study were summarized as follows; After 4 weeks of exercise, isometric lumbar extension strength was generally increased but there were only significant differences at $12^{\circ},\;24^{\circ},\;48^{\circ}$. The range of motion of lumbar extension was increased (p<.05). The isometric lumbar extension strength correlated with the range of motion of lumbar extension. In conclusion, our results have shown that lumbar stabilizing exercise influenced both lumbar extension strength and range of motion of lumbar extension.

Our purpose of this study was to determine the most effective cool-down exercise. The recovery times of dynamic strength after isometric and isotonic cool-down exercise were measured immediately post cool-down exercise, 30 seconds later and 60 seconds later in 30 normal, healthy men from 19 to 29 years, using dumbells(Model, Iron). The recovery time of dynamic strength had a significant positive correlation with isotonic and isometric cool-down exercise using the Chi-square method (p<0.01). Sources of significant differences were determined by the Wilcoxon signed-ranks test (p<0.01). The isometric cool-down exercise significantly shortened the recovery time of dynamic strength. We suggest that the isometric cool-down exercise may be more effective than isotonic cool-down exercise in shortening the recovery time of dynamic strength.

Purpose : This study aimed to investigate the effects of 12 weeks of resistance exercise on body composition, physical strength, blood lipids, and insulin. Methods : The study was conducted on 24 elderly women divided into two groups: 12 subjects in an exercise group and 12 subjects in a control group. Resistance exercise was performed for 50 minutes a day, three times a week, for the duration of 12 weeks, and body composition, physical strength, blood lipids, and insulin were measured before and after the subjects completed the program. For the statistical analysis, the mean and standard deviation (M±SD) of each variable were calculated using SPSS version 20, and a paired t-test and two-way repeated ANOVA were conducted to test for the differences before and after the resistance exercise. All significant levels were set to α=.05 as a result of the experiment. Results : Changes in body composition after the 12-week resistance exercise program did not show any significant difference based on the comparison between the groups, but when noting the values for body fat percentage and body in the control group before and after, a significant difference was shown in fat mass (p<.05). As for changes in physical fitness, significant differences appeared in flexibility, muscle strength, and stenotic force (p<.01) when the groups were compared. Regarding pre- and post-values within each group concerning flexibility within the exercise group, significant differences were shown in gender (p<.001), muscle strength (p<.05), (p<.01), muscle earth strength, equilibrium (p<.01), stenosis force, and cardiopulmonary earth force (p<.001). Also, comparisons between populations in changes in blood lipids the values before and after in each group, significant differences in glucose (p<.05) and insulin (p<.05) were shown in the exercise group. When comparing the values before and after in each population, a significant difference was shown in the control group (p<.05). Conclusion : When all the results were integrated, the 12-week resistance exercise program was found to enhance physical strength (flexibility, muscle strength, and coordination) and improve the blood sugar levels of elderly women. In particular, resistance exercise is believed to lower the prevalence of obesity, type 2 diabetes mellitus, and metabolic diseases by having a positive effect on insulin. Further studies are suggested to verify the effect on body composition and blood lipids by setting up a variety of exercise treatment methods (including subjects, exercise periods, exercise plans, and exercise intensity focuses).
