The purpose of this study was to investigate the relationship between physical activity participation habits, physical fitness level, and academic performance among the Reserve Military Training Corps (ROTC). Participants in the current study were 71 ROTCs from J University. Physical activity participation was investigated using the Global Physical Activity Questionnaire (GPAQ), and the level of physical fitness was measured by health-related physical fitness evaluation. For academic performance, university grade data (GPA) was approved by the head of the relevant school district, and the data were collected with the consent of the participants, and each data was analyzed. The correlation between physical activity participation habits, physical fitness level, and GPA was analyzed, and GPA by physical fitness level were compared. This study found that there was no statistically significant correlation between physical activity participation and academic performance. Otherwise, there was a statistically significant correlation between major subjects and total physical fitness score, cardiorespiratory fitness, muscular endurance, flexibility, and body composition. By the level of physical fitness, the ROTCs in the high-physical fitness group showed statistically significantly higher academic performance than the ROTCs in the low-physical fitness group. In addition, low level of physical fitness ROTC group was lower than the other. In conclusion, ROTCs with a high physical fitness level had a positive effect on improving learning ability compared to those who did not. By recommending an autonomous but systematic exercise training program, it is suggested to improve the physical strength of ROTCs and to cultivate excellent future military officers.

This study examined the relationship between body fitness and body composition as well as the body fluid and intracellular fluid (ICF) of extremities to determine body composition's quantitative criteria for body fitness. Multiple-frequency segmental bioelectrical impedance analysis and the physical fitness test provided by the Ministry of Education, Culture, Sports, Science and Technology were used to measure body composition and physical fitness, respectively. The test results showed that in women in their fifties, the correlation between the amount of body fluid in the upper limbs and grip strength was r=.654 (p<0.01) for the right arm and r=.445 for the left while that between the amount of ICF in the upper limbs and grip strength was r=.708 (p<0.01) for the right and r=.323 for the left. Also, in women in their fifties, the correlation between the amount of body fluid in the lower limbs and the result of a repetitive side jump test was r=.730 for the right leg and r=.753 for the left (p<0.01 for both), and that between the amount of ICF and the counts for the right and left legs was even higher with r=.742 and r=.763, respectively (p<0.01 for both). The body fluid and ICF volumes in the right extremities exceeded those in the left, and physical fitness was correlated with both body fluid and ICF. These findings indicate a connection between physical fitness and body fluid and ICF, suggesting that body composition may help predict physical fitness.

PURPOSE: The purpose of this study is to compare the effects of aerobic exercise and combination exercise on physical fitness, body composition, and depression and to observe the relationship between obesity and depression. METHODS: A total of 40 obese people were divided into an aerobic exercise group ($n_1$=20) and a combination exercise group ($n_2$=20) that was performed swiss ball exercise and aerobic exercise. Each group exercised three times per week for eight weeks. Outcome measures were basic physical fitness, body composition, and depression. RESULTS: After completion of the exercise, there was a significant difference in overall physical fitness factors of percentage body fat (%body fat), strength, muscle endurance, flexibility, cardiovascular endurance in the combination exercise group (p<.05). Strength, muscle endurance, flexibility, and cardiovascular endurance were more improved in the combination exercise group than aerobic exercise group (p<.05). However, changes of %body fat and psychological factor between the two groups were not significant. CONCLUSION: Combination exercise program has an effect on the solution of obesity in physical development and strength. Therefore, it seems to that use with better perform both aerobic exercise and Swiss ball exercise. In addition, the Swiss ball exercise, which is an easy, convenient and economical self-exercise that can be done at home, is recommended due to its positive effects on physical establishment and fitness.

The study aims to present a solution to the problem of police physical fitness tests as police officers, who tried to subdue the drunk in a video clip titled "Darim-dong female police officer Assault" in May in Seoul, showed a rather lethargic figure, such as being pushed out of a physical fight with the suspect. The police physical fitness test is subject to criticism as it consists of items that are difficult to apply in real life despite having to be linked to job performance. The problem is that the physical fitness test events are not realistic, the physical fitness test standards are set too low, and their credibility is not reliable due to the imbalance of standards between men and women and the vision culture of physical fitness testing methods. First of all, we hope that the Republic of Korea will become a world-class security powerhouse by upgrading its physical fitness standards and establishing a scientific fitness test system for preventing injuries and effectively measuring physical strength.

Special security guards working at nuclear power plants, one of the country's major facilities, serve as human protection to safeguard from threats to nuclear facilities and nuclear materials. The purpose of this study was to develop a physical fitness program for fitness management that is essential for the completion of missions of special guards. This program was designed to prepare the physical fitness test proposed by Jeong et al. (2019). Researchers conducted literature analysis, research meetings, expert meetings and pretests, and developed a 90-minute physical fitness program for 6 weeks, 3 times a week. In order to verify the effectiveness of the developed physical fitness program, the experiment was conducted on 29 subjects(control group: 15, exercise group:14). Specifically, a six-week physical fitness program was conducted for exercise groups, and the fitness test for a special security guard was conducted for all subjects before and after the experiment. As a result, it was found that the physical fitness program was effective in improving the performance of 20m shuttle run, leg tuck, 20m sprint & carry, and medicine ball back throw. Until recently, problems of neglecting fitness management of security guards have been pointed out. It is expected that the physical fitness program proposed by this study will be a practical alternative for security guards' fitness management.

Purpose: This study was conducted to investigate the effect of cigarette smoking on physical fitness (dominant hand grip power, dominant isokinetic leg muscle strength, abdominal muscle endurance, flexibility, cardiopulmonary endurance) and depression in patients with chronic low back pain. Methods: This study was a cross sectional study and subjects consisted of 60 young males with chronic low back pain. The subjects were allocated to two groups following a self-report survey: cigarette smoking group (n=25) or non-smoking group (n=35). Physical fitness (dominant hand grip power, dominant isokinetic leg muscle strength, abdominal muscle endurance, flexibility, cardiopulmonary endurance) were measured using objective methods and depression in patients with chronic low back pain was measured using the Korean version of center for epidemiologic studies depression (CES-D) scale. Results: The results of this study were as follows: In physical fitness, the cigarette smoking group showed a significant decrease in abdominal muscle endurance, flexibility, and cardiopulmonary endurance compared with the non-smoking group. Depression index (CES-D scale score) was significantly higher in the cigarette smoking group than in the non-smoking group. Conclusion: These results suggest that cigarette smoking had a negative effect on abdominal muscle endurance, flexibility, and cardiopulmonary endurance in patients with chronic low back pain. In addition, depression of patients with chronic low back pain was affected by cigarette smoking. Thus, we suggested that cigarette smoking may play a significant role in the deterioration of physical fitness and depression of chronic low back pain patients.

As the culture develops, the body of children nowadays improves, but their physical fitness is weaker than that of children in the past. If physical fitness strengthens through clothing, this must be the easiest and the most efficient long-range training method. To find out the solutions on the above mentioned problems through clothing, this study was made for the analysis of the correlations of clothing weight and physical fitness. The children's endurance upon cold can be explained by the physical fitness, and has relation with the clothing insulation. Therefore, motor ability was measured as an index of physical fitness and clothing weight was measured as an index of insulation. This observation was made in Spring and Fall, 1985, in which 339 kindergartners and their mothers were the subject. The results of the study were as follows: Physical fitness of children decreased in proportion to the clothing weight, and especially this can be seen in boys rather than in girls, and in Fall rather than in Spring. In case of the children who spent more time outdoors rather than indoors, who played in larger space, and who didn't have meat frequently, it turned out that their clothing weight was surprisingly lessened and their physical fitness was highly food.
