This study aims to demonstrate the effect of a transtheoretical model (TTM)-based physical activity program on the exercise behavior of adolescents using WhatsApp. The study was conducted with high school students (N = 185) in a pre-/posttest, quasi-experimental design. TTM-based text messages were sent to the intervention group (n = 95) over…

Background: Affective associations have been shown to predict physical activity, but interventions designed to manipulate affective associations are limited. Purpose: To increase physical activity through manipulation of affective associations toward physical activity using the values component from Acceptance and Commitment Therapy (ACT) in…

The purpose of the study was to examine the effectiveness of "efitbuddy," a theory-based smartphone application, on young adults' BMI, physical activity, and motivation across a 4-week intervention. Participants were a convenience sample of 312 (mean age = 19.4 ± 2.3 years) college students. A quasi-experimental design with the control…

Purpose: This study investigated the effects of the menstrual cycle on running economy (RE). Method: Eleven eumenorrheic female athletes (mean age: 21.18 [plus or minus] 3.65 years, height: 170.2 [plus or minus] 6.6 cm, VO[subscript 2]max: 49.25 [plus or minus] 9.15 mL[middle dot]kg[superscript -1][middle dot]min[superscript -1], and menstrual…

The purpose of the present study was to compare body composition and physical activity level between children and adults with Autism Spectrum Disorders (ASD). A sample of 78 children, adolescents and adults participated in the study. Anthropometrics and physical activity, using GT1M accelerometer, were assessed. Overweight and obesity prevalence…

The purpose of this study is to investigate the effect of aerobic and strength exercises on hematological parameters in sedentary women. To achieve the purpose of this study, a total of 23 volunteers including aerobic exercise group (AE, n: 10), strength exercise group (SE, n:13) were selected as participants. Two different exercises were applied…

Background: Individuals with intellectual disability (ID) have very low physical activity and low peak oxygen uptake (VO[subscript 2peak]), potentially explained by physiologically lower peak heart rates (HR[subscript peak]). Method: The present authors performed a retrospective analysis of a large data set of individuals with intellectual…

This study was to investigate the physical activity (PA) and quality of life (QoL) of sports department students (SDS) and other department students (ODS) attending university. A total of 300 university students participated in this study. 150 SDS (age; 20.67 ± 1.65 years) including 89 males and 61 females and 150 ODS (age; 19.45 ± 1.22 years) 56…

Purpose: This study aimed (1) to compare physical activity (PA) indicators, metabolic biomarkers, and comorbidity, (2) to investigate the relationship between PA indicators and metabolic biomarkers, comorbidity and (3) to identify barriers to PA in patients with type 2 diabetes (T2DM) who are using oral hypoglycaemic agent (OHA) or combined OHA…

Objective: The goal was to examine associations between body mass index (BMI) and lifestyle factors in African American community college students. Methods: Young adults, 18-25, who identified as African American were eligible to participate from 3/17 to 11/17. BMI, body image, discrimination, social roles, emotional and informational support,…

Adults with autism spectrum disorder and intellectual disability often do not engage in healthy levels of physical activity despite its many benefits. We conducted a randomized control trial to evaluate the effectiveness and feasibility of the Step It Up program, which used supported self-management strategies, on daily step counts, health…

The aim of this study is to examine the association between physical fitness and 2D:4D finger ratio of high school students engaged actively in sports. 23 licensed male athletes and 23 sedentary (n=46) high school students participated in the study voluntarily. The participants age, body weight, body mass index, 2D:4D finger measurement values…

Weight-related teasing is associated with reduced levels of physical activity in youth, but the importance of weight teasing experiences to the engagement of female college students in physical activity is yet to be determined. Thus, this study examined differences in physical activity engagement and physical activity enjoyment in female college…

Background: Behavioral interventions to prevent pediatric obesity have shown inconsistent results across the field. Studying what happens within the "black box" of these interventions and how differences in implementation lead to different outcomes will help researchers develop more effective interventions. Aim: To compare the…

Background: The purpose of this study was to evaluate the relationship between adolescents' adherence to the 5-2-1-0 goals and the number of completed Progressive Cardiovascular Endurance Run (PACER) laps. Methods: Participants included 1792 students aged 10 to 16 years who were randomly selected across 9 data collection periods between 2012 and…
