Post-exercise hypotension effects in response to plyometric training of 7- to 9-year-old boys with overweight/obesity: a randomized controlled study.

Background: Physical activity plays an important role on children with obesity. This study evaluated the effects of plyometric training on the anthropometry, body composition, and the blood pressure (BP) and heart rate (HR) of boys with obesity.

Methods: Boys aged 7 to 9 years old were divided in: non-trained (N.

Biological and behavioral correlates of body weight status among rural Northeast Brazilian schoolchildren.

Objectives: The increase in the prevalence of overweight/obesity in youth is a public health problem worldwide; however, few studies have investigated its prevalence and correlates in children from the Brazilian Northeast region rural zone. The purpose of this study was (1) to estimate the prevalence of children's weight status according to sex, age, and birth weight categories; and (2) to investigate the links between biological and behavioral factors and weight categories.

Methods: The sample comprises 501 children (248 girls), aged 7-10 years, classified as low weight, normal weight, overweight, and obese using body mass index cut-points.

Birthweight, body composition, and motor performance in 7- to 10-year-old children.

Aim: The aim of this study was to analyse the influence of birthweight on motor performance and body composition in children. Further, we investigated whether associations between birthweight and motor performance changed after adjustment for current height, body mass index (BMI), fat-free mass (FFM), and % body fat.

Method: A total of 483 children (251 males and 232 females) aged 7 to 10 years (mean 8.

Permanent deficits in handgrip strength and running speed performance in low birth weight children.

Objective: The main goal of this study was to verify the influence of low birth weight (LBW) on the physical fitness of children aged 7-10 years. The comparisons were subsequently adjusted for chronological age, gender, physical activity (PA), and body composition.

Methods: A total of 356 children of both genders born in Vitoria de Santo Antão (Northeast of Brazil) were divided into two groups according to their birth weight (LBW < 2.

Maternal low-protein diet-induced delayed reflex ontogeny is attenuated by moderate physical training during gestation in rats.

We evaluated the effects of moderate- to low-intensity physical training during gestation on reflex ontogeny in neonate rats whose mothers were undernourished. Virgin female Wistar rats were divided into four groups as follows: untrained (NT, n 7); trained (T, n 7); untrained with a low-protein diet (NT+LP, n 7); trained with a low-protein diet (T+LP, n 4). Trained rats were subjected to a protocol of moderate physical training on a treadmill over a period of 4 weeks (5 d/week and 60 min/d, at 65 % of VO₂max).
