Effects of High-speed Elastic Band Training on Physical Fitness and Muscle Function in Rural Community-dwelling Elderly: a Single-blinded Randomized Controlled Trial

Abstract

Background: Aging related decrease in muscle strength and flexibility leads to functional loss of physical ability. Power training is known to improve these capacities and helps in performing daily routine better. Therefore, we modified previously proven and certified sarcopenia intervention exercise for elderly in rural community and applied them to examine the effects on physical fitness and muscle functions to show its applicability. Methods: Subjects were divided into control and exercise group using single-blind method. Exercise group underwent high-speed elastic band training(concentric contraction in 1 second) 2 days per week for 12 weeks. Before and after the intervention, we performed body composition analysis, anthropometric measurement, blood test, blood pressure check, senior fitness test (SFT), upper body and lower body strength examination. Korean version of Physical Activity Scale for the Elderly (K-PASE), and Center for Epidemiological StudiesDepression Scale (CES-D) were also assessed. Results: Body weight in control group was significantly increased (Paired t-test: P＝0.008), although it was consistent in exercise group (Group×Time: P＝0.013). 30-second chair stand (P＜0.001) and 30-second arm curl (P＜0.001) of the senior fitness test were also significantly improved in exercise group compared to control. In addition, muscle strength of knee flexion (P＝0.034) and K-PASE score (P＜0.001) were improved in training group with statistical significance. Conclusions: The modified high-speed elastic band training for rural elderly improved muscle strength and daily physical performance. This result suggests a simple and easy to perform band training could be an excellent solution to prevent sarcopenia in rural elderly. It also supports the evidence that this program would be widely distributed. Korean J Health Promot 2015;15(4):254-261

Cognitive Function of Recipients of Primary or Secondary Defibrillator Therapy

“…The prevalence range of cognitive impairment in this study (3.1%–18.9%) is relatively lower than that in previous studies (24%–78.4%) 13,41 . However, the prevalence of cognitive impairment and the domains assessed in different studies may vary, making it challenging to compare prevalence across studies.…”

“…In this study, multiple comorbidities were present in the sample, which were predominantly HF (82.4%) and chronic kidney disease (92.2%). In a previous Korean study, 41 approximately 1 in 4 Korean patients with HF (24%) had general cognitive impairment as assessed by the Korean Mini-Mental State Examination. In the current study (mean age, 49.4–64.7 years; NYHA class I–II, 87.3%), cognitive impairment assessed by the same method was 6% to 8%.…”

Variations in the prevalence of cognitive impairment are dependent on heterogeneities in sample characteristics, assessment tools, and/or definitions of cognitive impairment.…”

Effect of an Integrated Healthcare Program for Korean Rural Older Adults: A Quasi-Experimental Study

“…However, the agriculture-specific environment, such as working long hours in an uncomfortable position, is causing chronic agrarianism and various diseases. Additionally, the increase in sedentary lifestyles due to mechanization of farming tools has amplified the prevalence of chronic diseases such as decreased muscle mass, excessive accumulation of body fat, cardiovascular disease, and metabolic syndrome in rural older adults [5]. Comparison of the prevalence of aging-related fragility between urban and rural areas revealed that it was 10.3% in urban areas and 17.4% in rural areas, and fragile older adults are reported to be vulnerable to fatigue and declining muscle strength [6].…”
