Background Several global studies have clarified the relationship of sarcopenia with inflammatory markers and atherosclerosis; however, these associations in Korean adults remain unclear. We evaluated whether low skeletal muscle mass is associated with atherosclerosis and inflammatory markers in Korean adults. Methods We analysed data from 1556 Korean adults who visited a Health Promotion Centre in South Korea. We assessed their brachial–ankle pulse wave velocity (baPWV) in a cross-sectional study to analyse the …

This study investigated the effects of an eight-week pre-season on-court volleyball along with strength and conditioning program on performance in squat jump (SJ) and countermovement jump without (CMJ) and with arm swing (CMJa); and whether the improvements in SJ contributed to improvements in CMJ and CMJa. Thirteen competitive female volleyball players completed an eight-week pre-season training program and their SJ, CMJ, and CMJa were assessed at the beginning and at the end of this period. Paired …

The Japanese version of the EuroQol 5 dimension, 5 level version (EQ-5D-5L) can now be used to quantitatively evaluate the health-related quality of life (QoL) in Japan. Locomotive syndrome (LS) is a concept advocated in Japan to describe a condition requiring care for musculoskeletal disorders. However, no detailed study on the relationship between this index and LS in Japanese health checkup has been reported. We aimed to evaluate the relationship between the Japanese version of the EQ-5D-5L and LS. We enrolled 477 …

Regardless of sex or body size, police tasks may require officers to change direction speed (CODS) under occupational loads. The purpose of this study was to investigate body composition and CODS in female and male police cadets in both unloaded and occupationally loaded conditions. Body composition and CODS of 51 female (FPC) and 70 male police cadets (MPC) were assessed. Six body composition indices were used Body mass index (BMI), percent body fat (PBF), percent of skeletal muscle mass (PSMM), protein …

Decreases in aerobic fitness during military operations have been observed in several studies. Thus, differences in training adaptations during a 6-month crisis-management operation were compared by using the change in endurance performance as the outcome measure. Sixty-six male soldiers volunteered for the study, consisting of pre–post assessments of blood biomarkers, body composition, physical performance, and the military simulation test (MST) performance. Physical training volume was self-reported. After the …

Background Age-related decreases in lean mass represent a serious health problem. We aimed to analyze the risks of rapid decreases in lean mass by age and sex in relatively young Korean adults during a 4-year follow-up study. Methods A total of 65,856 non-diabetic participants (59.5% men, mean age 39.1 years) in a health screening program were subjected to bioimpedance body composition analyses and metabolic parameter analyses at baseline and after 4 years. The participants were sub-divided according to age, and …

Background: The influence of ketogenic diet on physical fitness remains controversial. We performed a randomized controlled trial to compare the effect of cyclical ketogenic reduction diet (CKD) vs. nutritionally balanced reduction diet (RD) on body composition, muscle strength, and endurance performance.(2) Methods: 25 healthy young males undergoing regular resistance training combined with aerobic training were randomized to CKD (n= 13) or RD (n= 12). Body composition, muscle strength and spiroergometric parameters were …

Background The association between the Metabolically Healthy Obese (MHO) phenotype in the absence of metabolic syndrome and subsequent cardiovascular disease remains unclear. Objectives We examined the association between MHO and CVD risk in young Iranian women. Methods We studied 183 women aged 20-35 years from a population of 308 candidates. We classified participants into 4 phenotypes. We measured body composition, blood pressure, and biochemical factors in all participants. Results The Metabolically …

Objective: The aim of the study was to analyze the association of objectively measured sedentary time and physical activity with health-related quality of life in middle-aged women. Methods: The present cross-sectional analyses were performed in a total of 182 middle …

Background/Aim: The bioimpedance analysis (BIA) can provide anthropometric data on patients. The aim of the study is to evaluate the clinical relevance of these automatically obtained values. Patients and Methods: We studied the arm circumference (AC) and arm muscle circumference (AMC) of 197 histologically proven cirrhotic patients. The BIA-based anthropometric data were compared to the manually measured data. In addition, we evaluated whether or not the BIA-based anthropometric data were associated with the …
