The aim of this study is to analyze the relationship between body composition and physical fitness parameters in children. 286 male and 311 female students have voluntarily participated in the study. Data on body composition have been obtained through the measurements of the students' height, body weight, BMI, body fat percentage, length (sitting…

The purpose of this study was to compare measures of body size in two samples of youth baseball players with normative data from the United States National Center for Health Statistics (NCHS) growth charts. One sample of youth baseball players participated in a local little league. The second sample of youth baseball players were members of eight…

This study investigated the effects of a short period of severe protein malnutrition on subsequent growth and development in the squirrel monkey. A total of 12 newborn monkeys were fed a low protein diet from 2 to 8 weeks of age then rehabilitated by returning them to the 13 percent protein diet of the control group. Minimum amount of protein…

Objective: To study familial and nonfamilial environmental influences on attention problems and attention-deficit/hyperactivity disorder (ADHD) in monozygotic twins discordant and concordant-high and low for these traits. Method: Ninety-five twin pairs from The Netherlands Twin Register were selected. Longitudinal survey data were collected at 1,…

Results of research on the influence of body size and composition on peak force and maximal rate of static strength exertion as measured from force-time curves indicates that rate of force production is somewhat independent of peak force, yet influenced by body size and composition, as is peak force.

Examined longitudinally the effects of infants' age, body dimensions, and experience on the development of crawling. Although most infants displayed multiple crawling postures en route to walking, development did not adhere to a strict progression of obligatory, discrete stages. Duration of experience with earlier forms of crawling predicted the…

This study was designed to explore the effects of vestibular stimulation on the developmental behavior, respiratory functioning, weight and length gains, and morbidity and mortality rates of premature infants. A total of 20 infants participated in this study in 4 groups of 5 infants each. Group A infants were placed in a motorized hammock within…

This document is an English-language abstract (approximately 1,500 words) of a report on an investigation started in 1957 by Martti Takala and Penti Pitkanen at the University of Jyvaskyla, Finland, to examine the connections between physical fitness and other measures of individual difference. The report deals with the structure and development…

The effects of exercise in children can be assessed by physiological measures of the respiratory and cardiovascular body functions and by anthropometric measures of body composition and maturation. Several methods and techniques in these areas are available to the researcher and practitioner for attempting to assess the physiological aspect of…

One concern frequently cited regarding early childhood programs is that methods for assessing some of their more important objectives are inadequate or nonexistent. This paper addresses this concern in the areas of health, safety, nutrition, dental health, and physical development during the preschool years. An organizing framework for classifying…
