We present an alternative to the traditional classroom lecture on the topics of metabolic scaling, allometric relationships between metabolic rate (MR) and body size, and reasons for rejecting Rubner's surface "law," concepts that students have described as challenging, counterintuitive, and/or mathematical. In groups, students work with…

This study examined the relationship between the accuracy of parental reporting of children's sleep duration compared to objectively measured child sleep and tested whether any discrepancies were related to childhood obesity prevalence in a sample of Latinx families (N = 119). A paired sample t-test revealed that parents significantly…

The basic timescales governing animal life are generally determined by body size. Pauses in naturally occurring human speech were investigated to determine if pause timescales are also sensitive to body size. Reported is an analysis of pause duration allometry in recorded interviews of 61 athletes. Pauses were divided into three classes based on…

Objective: To examine a) whether college students' eating behaviors are different by students' sex and/or body mass index (BMI) categories and b) the correlations between college students' eating behaviors and the degree to which they rely on internal bodily signals for food intake. Participants: Undergraduate college students 18-24 years old at a…

Background: Little is known about the effects of outdoor behavioral healthcare on participants' body composition or about the relationship between body changes and indicators of mental health. Purpose: The purpose of the current study was to compare body and mental health changes in adolescents in an 8-week adventure therapy program.…

The relationship between dietary habits and microbiota composition during adolescence has not been well examined. This is a crucial knowledge gap to fill considering that diet-microbiota interactions influence neurodevelopment, immune system maturation and metabolic regulation. This study examined the associations between diet and the gut…

Field-based tests of aerobic fitness that can be administered quickly and do not require maximal effort are desirable. The purpose was to develop and validate quarter-mile walk tests for 10--13-year-olds. Participants (N = 59) walked one mile on two different days. Walk times, heart rates, body mass, physical activity, and aerobic fitness were…

This study investigated the relationship between children's mathematics performance and physical health using data from the Early Childhood Longitudinal Study Kindergarten Class of 2010-2011 (ECLS-K 2011). A two-level hierarchical growth curve model was used to explore the relationships between childhood mathematics performance and childhood…

Aims: To determine the effect of a 16-week fitness program (strength vs. aerobic) on different indicators of body composition and components of health-related physical fitness in youths with Down syndrome. Methods and procedures outcomes: Fifty adolescents (19 girls and 31 boys; average age, 18.33 ± 1.42 years) with Down syndrome were recruited…

Quantitative evidence synthesis methods aim to combine data from multiple medical trials to infer relative effects of different interventions. A challenge arises when trials report continuous outcomes on different measurement scales. To include all evidence in one coherent analysis, we require methods to "map" the outcomes onto a single…

Objective: The objective of this study was to examine changes in freshman students' objectively measured body mass index (BMI), physical activity (PA), and dietary behaviors (consumption of trans fats, sugars, and added sugars) during their first college semester. Methods: Twenty-eight participants (18.32 ± 2.2) completed the dietary (ASA24-US)…

The main aim of the present study was to identify motor difficulties in Greek preschoolers. Secondary aims were to identify possible differences in prevalence of motor difficulties related to gender, age, body mass index, place of residence, and hand preference. 302 preschoolers were assessed using the first age band (3-6 years) of the Movement…

Purpose: Previous research demonstrates a consistent association between the media and body and eating related issues in children. Recent research has highlighted a role for "fat talk" to describe discourses around body size and food. One key source of media information is Disney animation films, yet to date no research study has…

The worldwide increase in childhood overweight and obesity underscores the need to study variables like fundamental movement skill (FMS) levels from early childhood. This study investigated the bidirectional longitudinal relationship between body mass index (BMI) and process-oriented FMSs, including locomotor skills and object control skills in…

Purpose: This paper delves into the profound influence of societal beauty standards and the prevalence of body shaming in contemporary culture. It explores how these societal norms contribute to self-esteem issues and psychological distress among individuals, particularly young people. Design/methodology/approach: Through the poignant medium of…
