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).

Phase angle (PhA) is a marker of health and cellular integrity used as tool for predicting nutritional status in children with various conditions. Even though physical activity cardiorespiratory fitness have been shown to provide several benefits, few studies evaluated the relationship between PhA parameters, i.e., body composition. Thus, we aimed evaluate association aged 9 11 years. Twenty-three (52% girls) were tested cross-sectional study. The was calculated by bioelectric impedance...
The military are selected on the basis of physical standards and regularly involved in strong activities, also related to particular sports training. aims study were analyze effect a 7-month training program body composition variables suitability specific 'bioelectrical impedance vector analysis' (spBIVA), compared DXA, detect changes composition. A sample 270 male Brazilian cadets (19.1 ± 1.1 years), composed group practicing routine only (MT = 155) sport (SMT 115), measured by assessments...
Acute and chronic caffeine intakes have no impact on hydration status (R.J. Maughan J. Griffin, Hum. Nutr. Diet. 16(6): 411–420, 2003), although research has been conducted to analyze the effects using dilution techniques total-body water (TBW) its compartments. Therefore, aim of this study was investigate a moderate dose TBW, extracellular (ECW), intracellular (ICW) during 4-day period in active males. Thirty men, nonsmokers low users (<100 mg·day −1 ), aged 20–39 years, participated...
Abstract Objective The aim of the present study was to analyze tracking indicators health‐related physical fitness between childhood and adulthood. Methods presents a longitudinal design, with first phase data collection occurring annually 2002 2006, second carried out in 2016. A total 142 young adults, aged 21 25 years, both sexes participated study.

The phase angle is used to evaluate nutritional status and an indicator of cellular health. Cardiorespiratory fitness body composition are strong indicators health during adolescence. We aimed if cardiorespiratory have association with among adolescents. 203 girls 220 boys (12.8±1.3 years) were evaluated. Peak height velocity, percentage fat mass, fat-free fitness, measurements collected. Linear regression adjusted by peak velocity was verify predictor variables associated Phase showed...
