Dynapenia refers to muscle weakness related to aging and is defined as a loss of muscle strength associated with muscle quality. The purpose of this study is to identify the prevalence of dynapenia and associated risk factors by gender and age in domestic adults and to provide customized basic data for the prevention of dynapenia through its manage...
This study aimed to identify the prevalence and risk factors of sarcopenia for the disease in the Korean older adults, and to provide basic data for preventing the occurrence of sar-copenia through its management. Based on the data from 2008-2011 of the Korea National Health and Nutrition Survey, 3,485 subjects aged 65 or older who participated in...
The purpose of this study was to analyze the association between chronic renal fail-ure(CRF) and muscle strength. This study obtained data from the Korea national health and nutrition examination survey(KNHANES, 2019), a cross-sectional and nationally representative survey conducted by the Korean centers for disease control and prevention. Particip...
Background and Objective: This study aimed to identify the incidence of sarcopenia and disease risk factors in Korean adults and to provide data for sarcopenia prevention. Materials and Methods: Based on the Korea National Health and Nutrition Survey, 2008–2011, we selected 14,185 adults over the age of 20 who participated in sarcopenia diagnostic...
Background and Objectives: The goal of this study is to determine the prevalence of knee osteoarthritis (OA) and risk factors for the disease in Korean adults over the age of 50, as well as to provide basic data for OA prevention through management.

The effect of aerobic exercise at different intensities on Alzheimer’s disease (AD) still remains unclear. We investigated the effect of aerobic exercise at different intensities on cognitive and motor functions and neurotrophic factor expression. Thirty-two AD-induced rats were randomly assigned to control (CG), low-intensity (Group I), medium-int...
Chronic kidney disease (CKD) is caused by various factors such as chronic inflammation, oxidative stress, and obesity. Loss of muscle strength and mass is a negative prognostic factor for CKD. Therefore, in this study, we aimed to investigate the association between CKD and dynapenia in the Korean elderly. To this end, we analyzed 7029 participants...
Sarcopenia and anemia are common diseases in the elderly and are caused by various factors. In this study, the association between sarcopenia and anemia in an elderly Korean population was examined. The Korea Centers for Disease Control and Prevention’s cross-sectional, nationally representative Korea National Health and Nutrition Examination Surve...
This study assessed the association between sarcopenic obesity (S+O+) and coffee
intake in elderly Koreans. This study obtained data from the Korea National Health and Nutrition Examination Survey (KNHANES, 2008–2011), a cross-sectional and nationally representative survey conducted by the Korean Centers for Disease Control and Prevention. Of the 2...
Background: The aim of the present study was to investigate the effect of horse-riding simulator (HRS) exercise on balance control ability and gait in the elderly with dementia.
Material and Methods: This study was conducted on people aged 65 years or older living in D city (Korea) enrolled in the day care center with a diagnosis of dementia as doc...
Background and Objectives: Previous studies have revealed that independent variables (lower extremity strength, postural control ability, and body composition) influence gait performance and variability, but the difference in the relative influence between these variables is unclear. Hence, this study determines the variable that is the most influe...
Purpose: This study sought to investigate the effects of visual cue deprivation balance training by applying head control feedback to the balance function and the fall index in older people. Methods: The study was conducted on 26 older people at the S Hospital in Gyeongsansi. The patients were randomly divided into the experimental groupⅠ (EGⅠ, n=...
Background and Objectives: Visual cue deprivation is the instability of head control is increased. The purpose of this study is to investigate the effects of visual cue deprivation balance training by applying head control feedback to the balance and gait ability of stroke patients. Materials and Methods: The study was conducted on 41 patients diag...
Purpose: The aim of this study was to establish an association between grip strength and gait variability in the elderly. Methods: The participants in this experiment (n = 20) were aged 65 or older. Power grip and lateral pinch forces were obtained in grip strength tests, and spatiotemporal gait parameters were collected from IMU sensors during 6 m...
This study assessed the association between sarcopenia and metabolic syndrome in Korean adults aged over 50 years. The study obtained data from the Korea National Health and Nutrition Examination Survey (KNHANES, 2008–2011), a cross-sectional and nationally representative survey conducted by the Korean Centers for Disease Control and Prevention. Am...
Sarcopenia and bone disorders, such as osteopenia and osteoporosis, are common musculoskeletal disorders in older adults. Therefore, this study aimed to establish the association between sarcopenia and bone disorders such as osteoporosis and osteopenia according to sex. We analyzed 3077 participants from the 2008–2011 Korean National Health and Nut...
Objectives: This study examined the association between sarcopenia and spirometry patterns in the restrictive and obstructive patterns and investigated whether there were sex-specific differences.
Methods: This study obtained data from the Korea National Health and Nutrition Examination Survey (KNHANES, 2008–2011), a cross-sectional and nationally...
This study examined the effects of repetitive peripheral magnetic stimulation and exercises on pain, leg muscle strength, and WOMAC index in knee osteoarthritis patients. Twenty subjects were randomly assigned to experimental and control groups. rPMS and exercises were applied to the experimental group for 20 minutes per day, 5 times a week for a t...
Abstract
Background: This study was performed to establish the relationship between these diseases by analysing the prevalence of metabolic syndrome and its link to pulmonary dysfunction.

Background:
Diabetes is a progressive disease that increases glucose levels in the blood. While studies have shown that patients with pulmonary disease (both obstructive and restrictive pulmonary disease) have a higher prevalence of type 2 diabetes mellitus (T2DM), there have been more studies on restrictive patterns than chronic obstructive pulmo...
