This study examined the effects of combined exercise training for preventing falls on the physical performance, falling index, and balance in elderly women. All subjects (N = 32) were recruited and divided randomly to either a combined exercise group (n= 16, EX) or non-exercise control group (n = 16, CON). During 12 weeks of training, the subjects in the EX performed the combined exercise programs (three times/week, 60min/session), and the subjects in the CON maintained their ordinary lives. At the PRE, MID, POST tests, All subjects completed senior fitness tests(dynamic balance, two minutes walking, sit and stand for 30 seconds), tests for falling risk with Tetrax, and tests for posture balance with the spine balance 3D. After the baseline tests, two-way repeated-measures ANOVA with contrast testing was used with SPSS 21.0. Alpha was set to 0.05. In the results, the dynamin balance (p=.001), two minutes walking (p=.001), sit and stand for 30 seconds (p=.001), falling risk (p=.002), and posture balance (p=.034) in the EX were significantly different, but not in the CON. Thus, elderly females who performed combined exercise training for 12 weeks can increase their physical fitness & posture stability and reduce their falling risk.

The purpose of this research was to compare the effects of Danjeon Breathing exercise and walking exercise on physical fitness of middle-aged women. The Danjeon breathing exercise group(20) took health management counseling and performed an eighty-minute Danjeon breathing exercise three times a week for 12 weeks while the walking exercise group(25) took health management counseling and performed a walking exercise seven hours per week for 12 weeks. The control group(20) received only health management counseling. $VO_2max$, back strength, flexibility, balance, power and agility were measured using the Health Management System developed by the Korea Physical Science Institution. The collected data were analyzed by using the SPSS PC program and $x^2$, ANOVA, repeated measures of ANOVA and LSD. The result of this study are as follows: 1. There were significant differences on back strength, flexibility, agility and power among Danjeon breathing exercise group, walking exercise group and control group. The degree of back strength, flexibility and power of the Danjeon breathing exercise group was higher than that of the walking exercise group and the control group. The degree of agility of the walking exercise group was lower than that of the control group. 2. There were no significant differences on $VO_2max$ and balance among Danjeon breathing exercise group, walking exercise group and control group. In conclusion, Danjeon breathing exercise improves back strength, flexibility and power than walking exercise and walking exercise improves agility than Danjeon breathing exercise.

[Purpose] This study aimed to analyze the prevalence of hypertension according to the body mass index (BMI) and relative handgrip strength (RHGS) among elderly individuals in Korea. [Methods] We analyzed the data of 44,183 Korean elderly individuals over 65 years old (men: n = 15,798, age = 73.31 ± 5.04 years, women: n = 28,385, age = 72.14 ± 5.04 years) obtained from the Korean National Fitness Assessment in 2019. All the participants were categorized into three groups according to the BMI and RHGS; additionally, one-way ANOVA and logistic regression analysis were performed. [Results] Overweight (men: 1.16 odds ratio [OR] 1.06-1.26, 95% confidence interval [CI]; women: 1.15 OR, 1.07-1.23 95% CI) and obese (men: 1.54 OR, 1.42-1.66 95% CI; women: 1.44 OR, 1.36-1.53 95% CI) elderly individuals showed a higher prevalence of hypertension than elderly individuals with normal weight, after controlling for age. In men, a lower RHGS was associated with a higher prevalence of hypertension after controlling for age (weak RHGS: 1.09 OR, 1.00-1.17 95% CI; middle RHGS: 1.21 OR, 1.12-1.31 95% CI vs. strong RHGS). [Conclusion] A higher BMI was associated with the prevalence of hypertension in the elderly Korean population. In addition, a lower RHGS was associated with the prevalence of hypertension in elderly Korean men.

Purpose: The purpose of this study was to investigate the effect of stretching, muscle strengthening, and walking exercise on the cardiopulmonary function and health-related quality of life in hemodialysis patients. Methods: Twenty-one patients in the intervention and the control group participated in the exercise respectively on maintenance hemodialysis at four university hospitals. The exercise was composed of 20 to 60 min per session, 3 sessions a week for 12 weeks. The effect of exercise was assessed by cardiopulmonary function (peak oxygen uptake, peak ventilation, peak respiration rate, maximal heart rate, and exercise duration) using a cycle ergometer. Grip strength was measured by dynamometer, and flexibility was measured by sit and reach measuring instrument. Health-related quality of life was measured using Medical Outcomes Study Short Form-36. Results: Peak oxygen uptake, peak ventilation, peak respiration rate, exercise duration, grip strength, flexibility, and physical component scale were significantly improved in the intervention group after 12 week's exercise compared to the control group. Conclusion: These findings indicate the exercise can improve cardiopulmonary function, grip strength, flexibility, and physical component scale of health-related quality of life in hemodialysis patients.
