Abstract Background The loss of skeletal muscle mass (MM) or function (MF) alone increases the risk for losing physical independence in older adults. We aimed to examine independent and synergic associations low MM MF, both criteria sarcopenia, with projected later life (+90 years old). Methods Cross‐sectional analyses were conducted 3493 non‐institutionalized adults (1166 males). Physical was assessed a 12‐item composite scale. Logistic regression used estimate odds‐ratio (OR) being at...

Background Despite the importance of body composition in athletes, reference sex- and sport-specific data are lacking. We aim to develop values for anthropometric measurements athletes. Methods Body weight height were measured 898 athletes (264 female, 634 male), variables assessed 798 (240 female 558 481 (142 339 male) with dual-energy X-ray absorptiometry (DXA). A total 21 different sports represented. Reference percentiles (5th, 25th, 50th, 75th, 95th) calculated each value, stratified by...

Physical activity has many health benefits, and to implement strategies, mainly in those groups with insufficient levels of practice, it is important evaluate physical activity. The main purpose this study was describe the prevalence Portuguese population aged 10 yr older using accelerometry.The accelerometers were worn for four consecutive days, a valid record defined as at least 3 d h wear time, including one weekend day. Considering these conditions, 4696 participants included.According...

Physical function is a key determinant that corresponds to the physiological capacity of older adults perform normal everyday activities, safely and independently, without undue fatigue. We examined associations sedentary behavior (SB), breaks in time (BST), moderate-to-vigorous physical activity (MVPA) with adults.Physical SB were assessed accelerometers (ActiGraph, GT1M) Senior Fitness Test battery, among 87 males 128 females aged between 65 94 years. A composite Z-score was created based...

Background There is controversial evidence on the associations between anthropometric measures with clustering of cardiovascular disease risk factors in pediatric ages. We aimed to examine body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR) clustered cardiometabolic determine whether these variables can be used discriminate individuals increased (increased triglycerides, HDL-cholesterol, systolic diastolic blood pressure, HOMA-IR). Methods The study sample 4255...

This study determined the prevalence of overweight, obesity, and abdominal obesity in Portuguese adults examined relationship between above mentioned prevalences educational level. Body mass, stature, waist circumference were measured a representative sample population aged 18–103 years (n = 9,447; 18–64 years: n 6,908; ≥65 2,539). Overweight corresponded to body mass index ranging 25–29.9 kg/m2 ≥30 kg/m2, respectively. Abdominal was assessed as >102 cm for males >88 females. After adjusting...

The aim of this study was to examine the prospective associations between cardiorespiratory fitness (CRF) and academic achievement in youth.The sample included 1286 fifth-, sixth-, seventh-grade students, age 11 14 yr (Mage = 11.3 ± 1.1), from schools followed for 3 yr. Academic assessed using students' marks at baseline follow-up apart, Portuguese, mathematics, foreign language (English), science. CRF by Progressive Aerobic Cardiovascular Endurance Run test Fitnessgram battery. Students...

This study aimed to produce age- and sex-specific physical fitness reference data for Portuguese youth; report the prevalence of youth in healthy zone according FITNESSGRAM(®) criteria; verify agreement between percentiles zones. In 2008, 22,048 children adolescents (10-18 years) were evaluated. Physical (curl-ups, push-ups, 20-m shuttle run modified-back-saver-sit-and-reach tests) was evaluated using Test Battery 8.0. Smoothed percentile curves estimated Cole's LMS method. Boys consistently...

This cross-sectional study was designed to develop normative functional fitness standards for the Portuguese older adults, analyze age and gender patterns of decline, compare level adults with that in other countries, evaluate relative recently published criterion associated maintaining physical independence. A sample 4,712 independent-living 65-103 yr, evaluated using Senior Fitness Test battery. Age-group scores are reported 10th, 25th, 50th, 75th, 90th percentiles. Results indicate both...

Abstract: The aims of this study were to analyze the usefulness raw bioelectrical impedance (BI) parameters in assessing water compartments and fluid distribution athletes. A total 202 men 71 female athletes analyzed. Total body (TBW) extracellular (ECW) determined by dilution techniques, while intracellular (ICW) was calculated. Fluid calculated as ECW/ICW ratio (E:I). Phase angle (PhA), resistance (R) reactance (Xc) obtained through BI spectroscopy using frequency 50kHz. Fat (FM) fat-free...

Abstract Background Dual-energy x-ray absorptiometry (DXA) provides an affordable and practical assessment of multiple whole body regional composition. However, little information is available on the changes in composition top-level athletes using DXA. The present study aimed to assess accuracy DXA tracking (relative fat mass [%FM], absolute [FM], fat-free [FFM]) elite male judo from a period weight stability prior competition, compared four compartment model (4C model), as criterion method....

Changes in body components occur over a season, but their impact on performance is still unclear. We aimed to analyze the relationship between changes leg strength and jump with composition season highly trained athletes. Measures from beginning main competitive periods of were obtained 40 male 23 female basketball, handball volleyball players (20±5 years) for fat (FM) fat-free mass (FFM) estimated by DXA. Total water (TBW) extracellular (ECW) assessed deuterium bromide dilution,...

Background: Sedentary behavior has been considered an independent risk factor for type-2 diabetes (T2D), with a negative impact on several physiological outcomes, whereas breaks in sedentary time (BST) have proposed as viable solution to mitigate some of these effects. However, little is known about the associations pursuits, physical activity, and cardiorespiratory fitness (CRF) variables glycemic control. We investigated total time, BST, moderate-to-vigorous activity (MVPA), CRF outcomes...

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 Bioelectrical impedance analysis equations for fat-free mass prediction in healthy populations exist, nevertheless none accounts the inter-athlete differences of chemical composition mass. We aimed to develop a bioimpedance-based model based on four-compartment sample national level athletes; and cross-validate new models separate cohort athletes using 4-compartment as criterion. There were 142 highly trained (22.9±5.0 years) evaluated during their respective competitive seasons....

Magnesium plays significant roles in promoting strength. Surveys of athletes reveal that intake magnesium is often below recommended levels. We aimed to understand the impact on strength elite male basketball, handball, and volleyball players. Energy nutrient were assessed from seven-day diet record. Strength tests included maximal isometric trunk flexion, extension, rotation, handgrip, squat countermovement Abalakov jump, isokinetic knee extension flexion peak torques. Linear regression...

Abstract Dual energy X-ray absorptiometry (DXA) cannot be used to evaluate participants taller than the scan area. We aimed analyse accuracy of bone mineral content, fat mass, and lean mass assessed with DXA whole-body from sum two scans (head trunk plus limbs). Participants were 31 athletes (13 males 18 females) 65 non-athletes (34 females), that fit within Three performed using a Hologic Explorer-W fan-beam densitometer: as reference; head scan; limbs scan. The was alternative procedure....
