We aimed to establish jump power cut-offs for the composite outcome of either sarcopenia (EWGSOP2) or dysmobility syndrome using Asian and Caucasian cohorts. Estimated cut-offs were sex specific (women:< 19.0 W/kg; men:< 23.8 W/kg) but not ethnicity specific. Jump power has potential to be used in definitions of poor musculoskeletal health. Purpose Weight-corrected jump power measured during a countermovement jump may be a useful tool to identify individuals with poor musculoskeletal health, but no cut-off values exist. We …

Introduction: In contrast to obesity, little is known about the human lean phenotype associated with gut microbiota composition. Objective: We aimed to investigate whether the bacterial composition of lean athletes with a positive energy balance differs from the equal-calorie food group. Methods: Twenty-four male participants were included in this cross-sectional study: lean athletes with a positive energy balance (LA, n 12) and control group athletes (CTRLs, n 12). Nutritional data, resting and total energy expenditure, and body …

Today, obesity is a health threat in developed and developing countries. The most important disorders caused by weight gain and obesity are fatty liver disease, type 2 diabetes, and kidney failure [1]. In obese people, blood pressure rises to meet the needs of higher metabolism. Increased pressure inside the glomerulus can cause serious damage to the kidneys and increase the risk of chronic kidney disease in a long period. It can also be a risk factor for nephrolithiasis and several kidney malignancies, including kidney cancer [2]. The …

Gait assessment is important for identification of potential faller among the elderly populations. Slope walking is associated with fall risk factor and elderly women have higher fall rate compared with elderly men. Therefore, this study investigated gait characteristics of elderly women in overground and slope walkway conditions. Thirty healthy elderly women (15 younger-elderly women and 15 older-elderly women) walked along the linear walkway including three walking conditions (overground, ascent and descent conditions). Temporal …

Purpose The purpose of this paper was to translate and validate into the Korea language and setting the Sarcopenia Quality of Life (SarQoL®) questionnaire. Methods The participants consisted of 450 individuals in Namgaram-2 cohort who were followed up in 2019–2020. The study participants were divided into four groups:(1) SARC-F< 4,(2) SARC-F≥ 4 and robust grip strength,(3) SARC-F≥ 4, low grip strength, robust muscle mass,(4) SARC-F≥ 4, low grip strength, and low muscle mass. To assess construct validity …

PURPOSE: Some athletes consume alcohol prior to training and sports events, possibly because they believe that alcohol may aid in reducing pain and anxiety, increasing confidence, and promoting aggressiveness. While previous studies have shown that alcohol consumption acutely impairs endurance exercise performance, its effects on anaerobic exercise performance have not been well established. Therefore, this study investigated the effect of a small dose of alcohol on anaerobic exercise performance. METHODS: In a …

Objectives To investigate the body composition and dietary intake in the patients with head and neck cancer (HNC) during radiotherapy (RT), and explore the relationship between them. Methods This was a prospective, longitudinal observational study. Adult patients with HNC undergoing RT between March 2017 and August 2018 were recruited. Patients' body compositions were evaluated by bioelectrical impedance analysis, and dietary intake was recorded by 24-hour dietary recall at three time points, including baseline (T1), mid …

Abstract Aims/Introduction We carried out a multicenter clinical study to investigate whether the decrease in segmental phase angles (PhA values) observed using bioelectrical impedance is useful in screening for diabetes mellitus and monitoring disease progression. Materials and Methods The segmental PhA values of the four limbs were acquired using multifrequency bioimpedance at 5, 50 and 250 kHz in three clinics. Differences in PhA values between the diabetes and control groups were analyzed using the two‐sample t‐test …

Hypophosphatasia (HPP) is a rare disorder resulting from biallelic loss-of-function variants or monoallelic dominant negative variants in the ALPL gene. We herein describe the clinical outcome of a 32-year-old woman with childhood-onset HPP caused by compound heterozygous variants in ALPL. Her chief complaints were severe musculoskeletal pain, muscle weakness, and impaired daily activities necessitating assistance in housework and child-rearing in addition to a history of early tooth loss and mildly short stature. Asfotase alfa …

ABSTRACT Background and Objectives: Recent studies have shown the high prevalence of insulin resistance and zinc deficiency among hemodialysis patients. Zinc deficiency can be related to insulin resistance, as zinc is involved in the synthesis, secretion, action, and storage of insulin. This study aimed at evaluating the effect of zinc supplementation on lipid profile, insulin resistance, and as well as body composition in non-diabetic hemodialysis patients. Methods: In this placebo-controlled, double-blind, and randomized trial, 61 non …
