Objectives : The purpose of this study was to gain an understanding of the effects of three exercise types on anthropometric and serum lipids and physiological index factors, which are known to be the three risk factors of cardiovascular disease in male workers. Methods : The experimental study period was 12 weeks. In this study, 30-40's males (N=31) were assigned to 3 experimental groups: regular aerobic(treadmill walking) exercise group, regular anaerobic(muscular endurance) exercise group, irregular aerobic & anaerobic exercise group and a control group using a stratified random assignment method. Results : In relation to anthropometric factors, the regular aerobic & anaerobic exercise groups showed significant decreases in Weight, Broca's index, WC, BMI, WHtR, WHpR and HRrest. With regard to the serum lipid factors, the TC was decreased, but the HDL-c increased among the regular aerobic & anaerobic exercise groups. However, no significant difference was found between the other groups in respect to the LDL-c and TG. Considering the physiological factors, the TC/HD-c, TC-HDL/HDL-c, LDL-C/HDL-c and NON-HDL-c ratios were decreased, but the HDL-c/TC ratio increased among the regular aerobic & anaerobic exercise groups. The TG/HDL-c and HDL-c/LDL-c ratios showed no significant differences between the groups. These results indicated that the positive change for each factor is much larger in the regular exercise groups, especially in the anaerobic exercise group. Conclusions : The results indicate that not only regular aerobic exercise, but also regular anaerobic(muscular endurance) exercise could be utilized in lessening the deleterious effects of the risk index factors for cardiovascular disease.

The effects of Proprioceptive Neuromuscular Facilitation (PNF) and elastic band exercise on the physical functions and blood lipids of obese elderly women were investigated. The experimental group ($n_1=16$) patients underwent PNF for 12 weeks, and the control group ($n_2=15$) patients performed elastic band exercises. SPSS 21.0 was used to compute the means and standard deviations. After the 12-week PNF, both the experimental and control groups showed statistically significant differences in the physical functions (cardiovascular endurance, strength of the lower extremity, muscular endurance, flexibility, balance, and agility) (p<.05), but the difference in the experimental group was more significant than that in the control group (p<.05). In terms of the changes in the blood lipid levels (total cholesterol, triglycerides, high-density lipoprotein, and low-density lipoprotein), the experimental group showed significant changes (p<.05). In conclusion, PNF was confirmed as more effective than elastic band exercise in improving the physical functions and blood lipid levels of obese elderly women.

Purpose: This study was to investigate the effect of a 12-week plyometric training on body composition, physical fitness and bone mineral density in obese male adolescents. Method: Twenty adolescent boys who are obese were randomly assigned to a control group (CON, n=10) or plyometic exercise group (EXE, n=10). The EXE group was performed 3 times per week for 12 weeks. The body composition, physical fitness, and bone mineral density were measured before and after the 12 weeks intervention. Results: The results of this study were as follows: i) In EXE group, the fat mass was significantly decreased between pre and post, whereas the difference of the body weight, BMI, and LBM were not significant. ii) Among the physical fitness factors, grip strength, muscular endurance, and 2 0m shuttle running were significantly improved but flexibility did not show any significant difference. iii) The bone mineral density was significantly improved between pre and post in EXE group. Conclusion: These results suggested that plyometric training for 12 weeks may be effective in improving body composition, physical fitness, and bone mineral density in obese adolescents. Further implications were discussed.

Purpose: Exercise intervention after surgery has been found to improve physical fitness and quality of life (QOL). The purpose of this study was to investigate the feasibility and effects of a postoperative recovery exercise program developed specifically for gastric cancer patients (PREP-GC) undergoing minimally invasive gastrectomy. Materials and Methods: Twenty-four patients treated surgically for early gastric cancer were enrolled in the PREP-GC. The exercise program comprised sessions of In-hospital Exercise (1 week), Home Exercise (1 week), and Fitness Improvement Exercise (8 weeks). Adherence and compliance to PREP-GC were evaluated. In addition, body composition, physical fitness, and QOL were assessed during the preoperative period, after the postoperative recovery (2 weeks after surgery), and upon completing the PREP-GC (10 weeks after surgery). Results: Of the 24 enrolled patients, 20 completed the study without any adverse events related to the PREP-GC. Adherence and compliance rates to the Fitness Improvement Exercise were 79.4% and 99.4%, respectively. Upon completing the PREP-GC, patients also exhibited restored cardiopulmonary function and muscular strength, with improved muscular endurance and flexibility (P<0.05). Compared to those in the preoperative period, no differences were found in symptom scale scores measured using the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire (QLQ-C30) and Quality of Life Questionnaire-Stomach Cancer-Specific Module (QLQ-STO22); however, higher scores for global health status and emotional functioning were observed after completing the PREP-GC (P<0.05). Conclusions: In gastric cancer patients undergoing minimally invasive gastrectomy, PREP-GC was found to be feasible and safe, with high adherence and compliance. Although randomized studies evaluating the benefits of exercise intervention during postoperative recovery are needed, surgeons should encourage patients to participate in systematic exercise intervention programs in the early postoperative period (Registered at the ClinicalTrials.gov, NCT01751880).

Objectives: The purpose of this study was to know different effect with uncontrolled hypertension patients after providing health promotion program which consisted with medicine, exercise, nutrition. Methods: The subjects of this study was comprised by uncontrolled hypertension patients in spite of medication and didn't care the pressure by medication. The health promotion program was progressed by group exercise three times a week, nutrition education once a week and medical consultation once a month for 12 weeks. Subjects were measured for body composition(weight, fat mass, % body fat and body mass index), hemo-dynamics(systolic blood pressure(SBP), diastolic blood pressure(DBP), and resting heart rate), and physical fitness (cardiopulmonary endurance, muscular strength, muscular endurance, balance, and flexibility). Results: Groups showed significant improvement in every measure except resting heart rate. SBP is decreased both taking drug group about 18.4mmHg and without taking drug group about 19.4mmHg.(p<0.001) DBP is decreased both taking drug group about 8.7mmHg and without taking drug group about 9.0 mmHg.(p<0.001) Conclusion: There are no statistical significant differences of SBP and DBP decreasing effects by medication, Since effects of decreasing pressure are not different by medication, I think the health promotion program is effective to uncontrolled hypertension patients to decrease pressure.

Purpose: Sarcopenia is defined as a decrease in muscle mass, strength, and function with age that affects overall body function. We aimed to investigate the effect of combined training on body composition, balance, and muscle function in sarcopenia elderly. Research design, data, and methodology: Twenty-eight sarcopenia elderly (age 74.9±4.5 years) were randomly assigned to an exercise, EG (n=14), or a control, CG (n=14), group. The EG performed an intervention consisting of combined exercise training (60-75 min) for a total of 12 weeks, three times a week. The CG maintained their usual daily lifestyle during the intervention period. We measured body weight, body mass index (BMI), % body fat, free fat mass, balance ability, peak torque in shoulder, knee, and lumbar joints normalized for bodyweight in one second. Results: The EG showed improved body composition (i.e., BMI, fat-free body mass, fat mass; all p < 0.031, η² > 0.179), balance (i.e., right and left of static and dynamic balance and fast 10 m walk; all p < 0.049, η² > 0.152), and muscular function (i.e., 90°/sec and 180°/sec peak power per kg bodyweight, 90°/sec average power per kg bodyweight, 180°/sec total work, and 180°/sec endurance ratio; all p < 0.045, η² > 0.158). Conclusions: Combined exercise training improves muscle mass and strength, body composition, balance, and muscle function in sarcopenia elderly.

This study was conducted to investigate the effects of weight control program on nutrient intakes and physical fitness of Korean obese adult women. The subjects of this study were 33 obese adult women aged 30-65 years residing in Seoul. The weight control program for obese women included nutrition education, cognitive behavioral therapy and exercise for 12 weeks. There were significant decrease (p < 0.001) of blood pressure and atherogenic index of obese women after the weight control program. Energy intake was significantly decreased (p < 0.001) from 1556.9kcal to 1044.9kcal after 12 weeks of the weight control program. Also protein, fat and carbohydrate intakes were significantly decreased. The ratio of energy intakes per day for the subjects was carbohydrate 64% : protein 16% : fat 20%. The frequency of vegetables intakes was significantly increased (p < 0.05) and there were no significant differences in other food groups. After the weight control program, muscle endurance, flexibility, balance and explosive muscular strength of subject's physical fitness were significantly improved. These results suggest that the weight control program for obese women may contribute to nutrient intakes reduction and improvement of physical fitness.
