PURPOSE The aim of this research was to report the prevalence of overweight and obesity in a representative sample of Portuguese youth. METHODS This was a school-based study performed in Portugal. A total of 22 048 children and adolescents aged 10-18 years were included in the study. The World Health Organization (WHO) and the International Obesity Task(More)
OBJECTIVE The purpose of this study was to assess the associations and impact of increased meal frequency, physical activity and 'skipping' breakfast on obesity levels in a sample of urban adolescents, aged 13-17 years old, from Porto, Portugal. METHODS Overweight and obesity were defined according to age- and sex-specific BMI cut-points. Daily meal(More)
The aims of this cross-sectional study were 1) to estimate changes in body composition and cardiorespiratory fitness across stages of pubertal maturation, and 2) to describe the relationship between maturity status and body fatness, regional fat distribution, and cardiorespiratory fitness. The sample consisted of 494 children (254 males, 240 females), 8-16(More)
This study compared the effects of a resistance training protocol and a moderate-impact aerobic training protocol on bone mineral density (BMD), physical ability, serum osteoprotegerin (OPG), and receptor activator of nuclear factor kappa B ligand (RANKL) levels. Seventy-one older women were randomly assigned to resistance exercise (RE), aerobic exercise(More)
This study aimed to produce age- and sex-specific physical fitness reference data for Portuguese youth; to report the prevalence of youth in the healthy zone of physical fitness according to the FITNESSGRAM(®) criteria; to verify the agreement between the Portuguese physical fitness percentiles and the FITNESSGRAM(®) healthy zones. In 2008, 22,048(More)
OBJECTIVE The aims of this study were (1) to assess the relationships between transport to and from school (active vs. passive), sedentary behaviours, measures of socio-economic position and perceived environmental variables, and (2) to determine which, if any, variables were predictors of active transportation. METHODS The sample comprised 705 girls with(More)
Physical exercise is advised as a preventive and therapeutic strategy against aging-induced bone weakness. In this study we examined the effects of 8-month multicomponent training with weight-bearing exercises on different risk factors of falling, including muscle strength, balance, agility, and bone mineral density (BMD) in older women. Participants were(More)
Previously, data on the effects of muscle fatigue on joint position sense (JPS) have been provided. However, to our knowledge, no studies have been conducted so far to assess the effects of local muscle fatigue on elderly proprioception. Thus, the purpose of the present study was to determine the effects of local muscle fatigue on knee JPS in(More)
The aims of the this prospective study were to analyse physical activity (PA) engagement during the first and second trimesters, considering the different guidelines published on PA, to document the individual characteristics associated with the accomplishment of these guidelines and to examine pregnant women's perceived barriers to leisure PA, using a(More)
OBJECTIVES The aim of the current study was to develop sex and age-adjusted criterion-referenced fitness standards to predict independent physical functioning into later life. DESIGN Cross-sectional. SETTING National Survey of Physical Fitness and Physical Activity, Portugal. PARTICIPANTS A national representative sample of 3074 non-institutionalized(More)
