Objective: To analyze the association between relative handgrip strength (RHGS) and fat mass (FM) after controlling for the potential effect of maturity status.
Methodology: Both male and female children and adolescents aged ≥ 7.5 to ≤ 15.
Background: The importance of assessing body fat variables and physical fitness tests plays an important role in monitoring the level of activity and physical fitness of the general population. The objective of this study was to develop reference norms to evaluate the physical fitness aptitudes of children and adolescents based on age and sex from the lake region of Itaipú, Brazil.
Methods: A descriptive cross-sectional study was carried out with 5,962 students (2,938 males and 3,024 females) with an age range of 6.
Objective: This study aimed to determine the ability of different measures of adiposity to discriminate between low/high motor coordination and to evaluate the relationship between different measures of adiposity and motor coordination.
Methods: This study included 596 elementary school children aged 9 to 12 years (218 females - 47.1%).
Background: Health benefits of physical activity (PA) and physical fitness (PF) are reasonably well established, but tracking studies of PA and PF in childhood have not ordinarily considered the role of motor coordination.
Objectives: To compare the growth status, gross motor coordination (GMC), PA, and PF characteristics of children at 6 years of age relative to aerobic fitness (fit, unfit) and PA (active, sedentary) at 10 years.
Methods: 285 primary school children (142 girls, 143 boys) resident on the 4 main Azorean islands, Portugal, were measured annually (in the fall) from 6 to 10 years.
Background: This meta-analysis study aims to assess the efficacy of school-based and after-school intervention programs on the BMIs of child and adolescents, addressing the correlation between some moderating variables.
Methods: We analyzed 52 studies (N = 28,236) published between 2000-2011.
Results: The overall effect size was 0.
Objectives: This study was conducted to evaluate the relationship between objectively measured sedentary behavior (SB) and motor coordination (MC) in Portuguese children, accounting for physical activity (PA), accelerometer wear time, waist-to-height ratio, and mother's education level.
Methods: A cross-sectional school-based study was conducted on 213 children (110 girls and 103 boys) aged 9-10 in the north of Portugal during the spring of 2010. Accelerometers were used to obtain detailed objective information about daily PA and SB over five consecutive days.
Background: This study investigated the association between sociodemographic and behavioral factors and health standards based on physical fitness component scores in a sample of Brazilian schoolchildren.
Methods: A sample of 1457 girls and 1392 boys aged 6 to 18 years performed a test battery of 5 items: 1) sit-and-reach, 2) curl-up, 3) trunk-lift, 4) push-up, and 5) progressive endurance run (PACER). The cut-off scores for gender and age suggested by the FitnessGram were adopted.
Objective: To analyse the physical growth of a representative school population sample from the Jequitinhonha Valley, Minas Gerais, Brazil, in comparison with the reference proposed by the Centre for Disease Control and Prevention (CDC-2000).
Methods: The sample was composed of 5100 individuals (2730 girls and 2370 boys), aged 6-18 years. Body weight-for-age and height-for-age percentiles were obtained using the LMS method.
Background: Several methods exist to asses and control physical intensity levels of subjects engaged in physical activities programs, accelerometry is a method that could be easily used in the field. The purposes were: to calibrate Actigraph in middle-aged to old obese/overweight and DM2 adult patients; and to determine the threshold counts for sedentary, light, moderate, and vigorous physical activity (PA).
Methods: Sample comprise 26 participants (62.
