This study investigated the relationship between physical performance tests and body fatness in young children, and the extent to which differences in performance between the sexes could be explained by differences in body fatness. Measurements of age, height, weight, skinfold thicknesses, and performance scores on the vertical jump, standing…

This monograph describes the patterns, sequences, and timing of physical changes during adolescence for 94 girls studied longitudinally from childhood to maturity. Amount of growth attained, increments, and velocities of growth for several somatic dimensions are analyzed. Results are compared with corresponding findings obtained in an earlier…

This article reports the level of androgynous development found in university students attracted to the sport experience. The Bem's Sex Role Inventory (BSRI) was administered to 45 female physical education majors 20 female varsity athletes, 35 male physical education majors and 45 male varsity athletes at the University of Pittsburgh. Percentages…

This paper reviews some of the maturational events that are applicable in studying psychological effects of pubertal status and timing. Nine changes are reviewed (bone, height, weight, body fat, breast, body hair, penile, testicular, and menarcheal changes) in terms of measurement techniques, psychometric properties, and intercorrelations with…

This study compared the body mass index (BMI) of 118 children with infantile autism with corresponding BMI percentiles in age-and sex-matched reference populations. The BMI distribution of the male children was significantly lower than that of the age-matched reference population. BMI was not associated with intelligence or socioeconomic status.…

As a result of discussions at a 1983 Social Science Research Council meeting, a study group was convened to bring together all the professionals currently examining maturation timing. This interdisciplinary group reports findings in two issues of this journal, and its work is introduced in this paper. (LMO)

Examined relations between children's temperament, ability overestimation, and accidental injuries. Found that watching peer failure on physical tasks was related to conservative ability judgments for same task. Surgency/Undercontrol was related to 6-year-olds' judgment accuracy and to 8-year-olds' decision times. Ability overestimation was…

Examined associations between pubertal development and parent-adolescent conflict in urban, low-income African-American adolescents. Found that parents reported more verbal aggression with sons during midpuberty than early or late puberty, more violent tactics with younger than older daughters, and more "hot" discussions with early-…

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…

Height, weight, and triceps skinfold were measured in 1,680 Mexican American children, 10 through 14 years of age, from the Lower Rio Grande Valley (LRGV) region of Texas. Study sample measurements were compared to those gathered in 1972 involving LRGV Mexican American children as well as National Center for Health Statistics (NCHS) reference data…

Effects on adjustment of biological maturation and social timing were compared using data from a longitudinal sample of 335 young adolescents, who were followed from the sixth through eighth grades. (Author/LMO)

The fifth in a series of reports presenting analyses and discussions of data on height, weight, and 28 other body measurements taken from a probability sample of noninstitutionalized children in the United States aged 6-11 years, this document compares the growth patterns of white and Negro children for 20 body measurements. Emphasis is placed on…

This booklet pertains to the size and the form of the human body in infancy, childhood, adolescence, and adulthood. Historic and current information is presented for individuals in population groups of the Americas, Europe, Asia, Africa, and the Pacific. Differences in size and growth patterns between urban and rural individuals of the same racial…

An abundance of research relative to physical fitness and, more generally, physical education of school children, has surfaced during the past few years. Negative aspects of health and physical fitness are increasing year by year, and further evidence suggests that academic performance is negatively affected by low levels of fitness. A survey was…
