How magnetic resonance (MR) derived thigh muscle volume and deuterated creatine dilution mass (D3Cr mass) differentially relate to strength, fitness, other functions in older adults-and whether associations vary by sex-is not known. Men (N = 345) women 482) aged ≥70 years from the Study of Muscle, Mobility, Aging completed leg extension strength (1-repetition max) cardiopulmonary exercise testing assess fitness (VO2peak). Correlations adjusted regression models stratified sex were used...
Abstract Background Exercise is a well-accepted strategy to improve lipid and inflammatory profile in individuals with type 2 diabetes (T2DM). However, the exercise intensity having most benefits on lipids markers patients T2DM remains unclear. We aimed analyse impact of 1-year combined high-intensity interval training (HIIT) resistance (RT), moderate continuous (MCT) RT T2DM. Methods Individuals (n = 80, aged 59 years) performed randomized controlled trial were into three groups (control, n...
Abstract Objective The aim of this study was to examine associations ectopic adipose tissue (AT) with skeletal muscle (SM) mitochondrial bioenergetics in older adults. Methods Cross‐sectional data from 829 adults ≥70 years age were used. Abdominal, subcutaneous, and visceral AT thigh fat infiltration (MFI) quantified by magnetic resonance imaging. SM energetics characterized vivo ( 31 P‐magnetic spectroscopy; ATP max ) ex (high‐resolution respirometry maximal oxidative phosphorylation...
ABSTRACT Whole-body and regional raw bioelectrical impedance analysis (BIA) parameters have been used to develop lean soft tissue estimation prediction models. Still, no fat mass (FM) assessment models provided. Hence, we aimed validate BIA-derived equations predict FM against dual-energy X-ray absorptiometry (DXA) in healthy adults. One hundred forty-eight adults (77 females) were included this cross-sectional investigation. DXA assessed whole-body FM, of distinct body regions measured...
Background The use of lean soft tissue (LST) mass as a surrogate measurement skeletal muscle (SMM) has led to the conclusion that loss is poorly related functional decline. We hypothesized when using more accurate measure SMM determined by D 3 -creatine dilution (D Cr), longitudinal changes in will be similar magnitude strength and physical performance partially mediate relationship age with these outcomes. Methods measured change Cr (kg), handgrip 6m walk speed (m/s) 208 men from...
Abstract Background/objectives Moderate‐to‐vigorous physical activity (MVPA) and breaks in sedentary time (BST) have been proposed as viable solutions to improve an older adult's independence, whereas (ST) has associated with detrimental effects. We sought assess the joint effects of ST, BST, MVPA on independence adults determine whether what extent ST relationship is moderated by and/or BST. Design Cross‐sectional.

Prolonged periods of sitting have been linked to negative health outcomes. Implementation sit-stand desks in the workplace has one strategy reduce prolonged sitting.
Bioelectrical impedance analysis (BIA)-derived phase angle (PhA) has been used to assess cellular health in various populations, but its usefulness as a tool for measuring muscular performance adult athletes not extensively investigated. Our investigation examined the association of whole-body (WB) PhA with 117 from different sports and additionally assessed whether regional was better indicator compared WB, while accounting lean soft tissue (LST). Muscular handgrip strength countermovement...
Background: Physical activity (PA) and physical fitness (PF) are crucial for bone health. However, children participating in competitive sports with high PA at a greater risk of fracture from trauma or overuse. Given the importance development during adolescence, associations between commonly used tests distal third radius (R-SoS) midshaft tibia (T-SoS) speed sound by quantitative ultrasound were assessed adolescent athletes nonathletes. Hypothesis: The relationship R-SoS T-SoS will differ...
Objectives Muscle power is important for an older adult’s physical independence and can be easily estimated using the sit-to-stand test. This investigation aimed to assess whether muscle test could identify adults at risk of losing beyond handgrip strength, activity, sedentary time develop minimal thresholds. Design Physical was assessed cross-sectionally in a composite function questionnaire. calculated 30-sec strength determined dynamometer. activity were by accelerometry. Multiple...
Assessment of trends in physical activity (PA) and sedentary time (ST) is important for evaluating the effectiveness national policies setting goals to improve population PA. This study describes changes measured PA ST through motion sensors Portuguese from 2008 2018.PA were with accelerometry individuals (≥10 yr) participating ( n = 4 532) 2018 6 369) Surveillance Systems. Changes analyzed using generalized linear logistic models adjusted accelerometer wear time. A weight factor was applied...
Childhood overweight and obesity remains high, contributing to cardiometabolic risk factors at younger ages. It is unclear which measures of adiposity serve as the best proxies for identifying children metabolic risk. This study assessed whether DXA-derived direct are more strongly related in than indirect measures. Anthropometric DXA a comprehensive assessment were obtained 288, 9–12 year old girls, most being Hispanic ethnicity. Multiple regression models each parameter run against measure...
Evidence on correlates relies subjective metrics and fails to include across all levels of the ecologic model. We determined which best predict sensor-based physical activity (PA), sedentary time (ST), self-reported cell phone screen (CST) in a large sample youth, while considering multiplicity correlates.Using accelerometry, we assessed PA ST 2179 youths. A χ2 automatic interaction detection algorithm was used hierarchize associated with too much (> 50th percentile), insufficient...

Abstract Background The relationship between amino acids, B vitamins, and their metabolites with D3-creatine (D3Cr) dilution muscle mass, a more direct measure of skeletal has not been investigated. We aimed to assess associations plasma D3Cr as well strength physical performance in older men from the Osteoporotic Fractures Men cohort study. Methods Out 1 425 (84.2 ± 4.1 years), lowest mass (n = 100), slowest walking speed grip random sample 200) serving comparison group low groups were...
