There is a common assumption that changes in developmental movement patterns (process) leads to better skill outcome performance (product); however, limited longitudinal data evaluate this assumption. This study examined (a) the longitudinal relationship among process and product motor skill scores across early childhood (3.5-6 years) and (b) the…

Food insecurity has been identified as an understudied risk factor for weight-based stigma and discrimination. This study leverages data from 1,904 working-age adults to examine the food insecurity--weight-based discrimination relationship, as well as tests gender differences for this association. Logistic regression models revealed that food…

I provide novel evidence on the role of imperfect information in shaping childhood obesity. Between 2003 and 2017, 24 states began requiring schools to perform Body Mass Index assessments on students. Using the 1991 to 2017 National and State Youth Risk Behavior Surveys and a stacked difference-in-differences identification strategy, I show that…

Purpose: The purpose of this study was to investigate the effect of HIIT training on body composition and fitness in female adolescents and compare with regular physical education classes. Method: A total participant sample consisted of 40 adolescent females from the secondary grammar school, who were randomly assigned to the experimental group…

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…

Objective: Social physique anxiety (SPA) is characterized by concerns of evaluation focused on one's physical appearance. Past work suggests factors such as gender, body mass index (BMI), and exercise habits uniquely contribute to SPA. However, no study has examined the interactions between these three variables. The current study sought to…

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…

Objective: To examine the interaction between high school (HS) sports participation and injury history with current moderate-to-vigorous physical activity (MVPA) among young adults. Participants: Participants (N = 236) were 18-25 years old, not currently injured, and reported no physical activity limitations. Methods: Participants completed online…

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.…

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…

A disadvantage to online clothes shopping is the inability to try on clothing to test the fit. A class project is discussed where students consult with the CEO of an online mensware clothing company to explore ways in which an online clothing customer can be assured of a superior fit by developing statistical models based on a shopper's height and…

To target improving the physical fitness for female college students and to meet the individualized needs of different subgroups. A total of 6987 female college students from a teacher training college were assessed for physical fitness. Their fitness indices were analyzed using K-means clustering and GBDT regression algorithms. Based on physical…
