Monte Carlo methods can be used in data analytic situations (e.g., validity studies) to make decisions about sample size and to estimate power. The purpose of using Monte Carlo methods in a validity study is to improve the methodological approach within a study where the primary focus is on construct validity issues and not on advancing…

Aim: We have previously demonstrated improved cognitive performance after a classroom-based exercise regime. In this study, we examined the reproducibility of this effect in a more socio-economically diverse sample and also investigated whether cognitive benefits of exercise were moderated by body mass index (BMI) or symptoms of…

Objective: Among college students, several studies have found a positive relationship between physical activity and alcohol use. The current study tested gender, Greek status, and ethnicity as potential moderators of the physical activity-alcohol use relationship. Participants: Participants were college freshmen (n = 310) endorsing alcohol/drug…

Purpose: The exercise self-efficacy scale (ESES) is largely used among diabetic patients to enhance exercise behaviour. However, the Iranian version of ESES was not available. The aim of this study was to validate ESES in this country. Method: Data were collected from 348 women who referred to a diabetes institute in Iran through convenience…

The use of informal writing is common in sociology. This article presents one model for integrating informal written work with learning goals through a theoretical framework known as concentric thinking. More commonly referred to as "the PTA model" because of the series of cognitive tasks it promotes--prioritization, translation, and analogy…

Purpose of the study: To assess the recruitment, adherence, and retention of urban elderly, predominantly African Americans to a falls reduction exercise program. Design and methods: The randomized controlled trial was designed as an intervention development pilot study. The goal was to develop a culturally sensitive intervention for elderly…

Afterschool programs have continued to grow in sophistication, increase their offerings and improve quality. As the role of afterschool programs has evolved from primarily providing a safe and supervised environment to a resource that provides a host of supports for their students, programs have become valuable partners in helping students reach…

Afterschool programs continue to make advances when it comes to providing students with nutritious foods, keeping them physically fit and promoting health. Such programs have great potential to help prevent obesity and instill lifelong healthy habits, serving more than 10 million children and youth across America, with more than 19 million more…

Saliva provides a convenient and noninvasive matrix for assessing specific physiological parameters, including some biomarkers of exercise. We investigated whether the total protein concentration of whole saliva (TPWS) would reflect the anaerobic threshold during an incremental exercise test. After a warm-up period, 13 nonsmoking men performed a…

Exergames are videogames that require gross motor activity, thereby combining gaming with physical activity. This study examined the role of competitive versus cooperative exergame play on short-term changes in executive function skills, following a 10-week exergame training intervention. Fifty-four low-income overweight and obese African American…

Childhood obesity trends have increased dramatically over the past three decade's. The purpose of this quantitative systematic review is to provide an update of the evidence, illustrating the efficacy of childhood obesity treatment, considering whether treatment fidelity has been measured and/or reported and whether this related to the treatment…

The authors examined holistic wellness factors and drinking and driving behaviors among undergraduate students. Two factors of the Indivisible Self Wellness Model, the Coping Self and the Physical Self, decreased the odds of engaging in drinking and driving behavior. (Contains 2 tables and 1 figure.)

Objective: This study investigates college students' behaviors in response to the calories ingested by drinking alcohol. Participants and Methods: A sample of 274 nonclinical undergraduate alcohol drinkers completed an online survey asking about behaviors that students employed to make up for calories in alcohol or to get drunk more effectively.…

The effect of strength training on body image is understudied. The Strong Women Program, a 10-week, twice weekly strength-training program, was provided by Extension agents to 341 older rural women (62 ± 12 years); changes in body image and other psychosocial variables were evaluated. Paired-sample t-test analyses were conducted to assess mean…

This study aims to examine the relationship between sleep duration and body mass index (BMI) in two South Korean samples: children and adolescents. Nationally representative secondary data (i.e., the Korean Survey on the Obesity of Youth and Children) collected in 2009 were analyzed ("N" = 2,499 for children and "N" = 7,431 for…
