Abstract Our aim was to analyze the joint association of parental characteristics and offspring obesity indicators with metabolic risk in adolescents. A cross-sectional study was carried out with 972 adolescents and their parents.

SUMMARY Body composition assessment at the molecular level is relevant for the athletic population and its association with high performance is well recognized. The four-compartment molecular model (4C) is the reference method for fat mass (FM) and fat-free mass (FFM) estimation. However, its implementation in a real context is not feasible. Coaches and athletes need practical body composition methods for body ...
ABSTRACT Introduction Although resistance training (RT) can provide numerous benefits for both men and women, morphological, neuromuscular, metabolic, physiological, and behavioral differences between sexes may influence the magnitude of training responses. Objective To analyze the impact of 16 weeks of progressive RT on strength endurance in untrained men and women. Methods Twenty-eight men and 31 women (18-30...

Abstract Our aim was to identify prenatal, biological and environmental correlates of child to adolescence physical activity maintenance in 1,186 Brazilian youth (525 boys) aged between 10 and 16 years. Current and former physical activity levels were obtained cross-sectionally through questionnaires. As potential correlates, parent’s activity levels, socioeconomic status and offspring’s birth weight were self-...
ABSTRACT BACKGROUND: Our aim was to analyze multilevel correlates of cardiorespiratory fitness (CRF) according to sex, nutritional status and maturity status among adolescents. DESIGN AND SETTING: Cross-sectional study conducted in public schools. METHODS: This was a cross-sectional study on 1,209 adolescents aged between 10 and 17 years. CRF was estimated from the 20-meter shuttle run test. Anthropometric data...
