Effect of the Virtual Reality-Infused Movement and Activity Program (V-MAP) on Physical Activity and Cognition in Head Start Preschoolers
Background/Objectives: This study examined the efficacy of a physical activity (PA) intervention augmented by a non-immersive Virtual Reality (VR) gaming system (i.e., Virtual Reality-infused Movement and Activity Program; V-MAP) on physical activity (i.e., sedentary behavior, moderate-to-vigorous PA [MVPA], vigorous PA [VPA]) and cognitive skills (i.e., response error, movement latency and reaction time) in Head Start preschoolers. Methods: Usin…
The Associations of Physical Activity and Health-Risk Behaviors toward Depressive Symptoms among College Students
Engaging in health-risk behaviors (HRBs) may be correlated with depressive symptoms among college students, but these relationships require more research. The purpose of this study was to examine the associations of physical activity levels (i.e., light [LPA] and moderate-vigorous [MVPA]) and HRBs (i.e., sedentary behavior [screen-based and non-screen-based behavior] and cigarette and e-cigarette tobacco use) with depressive symptoms in a sample …
Disparity in Built Environment and Its Impacts on Youths’ Physical Activity Behaviors During Covid-19 Pandemic Restrictions
Adolescents’ Behaviors, Fitness, and Knowledge Related to Active Living before and during the Covid-19 Pandemic
The findings confirm the disruptive impact of the COVID-19 pandemic on adolescents' active living but varied by school grade and gender. The favorable changes from T2 to T3 observed for fitness and other constructs may be partially attributable to an interrupted fitness education intervention. The findings may guide the design and evaluation of future interventions addressing the physical inactivity pandemic during public health crises (e.g., COV…
Association of Cardiorespiratory Fitness and Cognitive Function with Psychological Well-Being in School-Aged Children
Cardiorespiratory fitness and cognitive function are significant correlates and predictors of PWB among school-aged children. The students with a higher level of psychological well-being showed a higher cardiorespiratory fitness, concentration performance, and attention accuracy compared to the lower level of PWB group
Adolescents’ Physical Activity and Depressive Symptoms
Guided by the Theory of Planned Behavior (TPB; Ajzen, 1991), this study aimed to test a hypothesized path model of TPB variables (i.e., attitude toward behavior, subjective norm, perceived behavioral control, and intention) with physical activity (PA) and depressive symptoms. A total of 792 Chinese adolescents ( M age = 16.9; SD = 0.82; 54.5% females) completed previously validated questionnaires assessing their TPB variables, PA, and depressive …
Does Perceived Competence Mediate between Ball Skills and Children’s Physical Activity and Enjoyment
The major purpose of this study was to examine the potential mediating role of perceived motor skill competence on relationships between actual ball skills and children's physical activity (PA) and PA enjoyment. A total of 294 students ( M age = 10.96 ± 0.76; 51.7% boys) from three elementary schools completed validated questionnaires assessing their perceived competence, self-reported PA, and PA enjoyment. Students' actual ball skills (i.e., bas…
A Mediation Analysis of the Association between Fundamental Motor Skills and Physical Activity during Middle Childhood
The purposes of the study were: (1) to investigate the associations between fundamental motor skills (FMS), health-related fitness (HRF) and physical activity (PA) during middle childhood; and (2) to examine whether HRF serves as a mediator in these pathways. The participants were 342 children (156 girls; Mage = 8.40, SD = 0.50) recruited in Texas. Children's FMS (locomotor and ball skills) were assessed. School-based PA that included light, mode…
The Impacts of Coordinated-Bilateral Ball Skills Intervention on Attention and Concentration, and Cardiorespiratory Fitness among Fourth-Grade Students
The CBBS group demonstrated a significant improvement in concentration performance and attention span over time, compared to the comparison group. Both groups improved their focused attention and attention accuracy as well as cardiorespiratory fitness over time. This study suggests that teaching ball skills in team sports for extended periods is instrumental to developing cognitive functions and cardiorespiratory fitness, though the CBBS lessons …
Longitudinal Effects of Motivation and Physical Activity on Depressive Symptoms among College Students
High prevalence of depression and physical inactivity have been consistently reported among college students, especially in females. Guided by Lubans et al.'s conceptual framework, the primary purpose of this study was to examine the longitudinal relationships of PA motivation with leisure-time PA and depressive symptoms among college students over one academic year. Employing a longitudinal repeated measure design, 1004 college students in China…
Physical Fitness Promotion among Adolescents
The major purpose of this study was to examine the effects of a jump rope-based physical activity afterschool program on middle school students' physical fitness. Sixty students ( M age = 13.37, SD = 0.58; 53.3% female) participated in a 12-week jump rope-based afterschool program (45 min/time, three times/week). Participants were randomly assigned to three groups: (a) freestyle rope skipping ( N = 20), traditional jump rope ( N = 20), and a cont…
Psychosocial Mechanism of Adolescents’ Depression
Depression has become the most prevalent mental health problem in developing countries, and especially among adolescents. Lubans and his colleagues proposed a psychosocial mechanism to understand the trajectory of mental health (i.e., depression). Thus, this study aimed (1) to examine the relations between different doses of physical activity (PA), light PA (LPA), moderate PA (MPA), and vigorous PA (VPA), academic self-efficacy, and depression am…
Effects of a Need-Supportive Motor Skill Intervention on Children’s Motor Skill Competence and Physical Activity
A need-supportive environment can provide various motivational benefits to impact children's psychomotor developmental levels. However, very little is known about the effects of need-supportive motor skill intervention on children's motor skill competence and physical activity by gender. Guided by self-determination theory (SDT), this study aimed to (a) investigate the effect of a need-supportive fundamental movement skill (FMS) program on childr…
Effects of a Fundamental Motor Skill-Based Afterschool Program on Children’s Physical and Cognitive Health Outcomes
Globally, more than half of school-aged children do not engage in the recommended 60 minutes of daily moderate to vigorous physical activity (MVPA). Given that developing sufficient fundamental motor skills (FMS) competence during early elementary school years is important for a child’s physical and cognitive development, the purpose of this study was to examine the effects of an 8-week FMS-based afterschool program on physical and cognitive heal…
The Roles of Individual and Psychosocial Factors in Predicting Quality of Life Among Working Women in Shanghai
Working women are at a high risk of suffering from occupational stress and burnout, which can result in reducing Quality of Life (QoL). Guided by the QoL construct and Luban et al.'s conceptual framework, this study aimed to (a) investigate the roles of individual factors (i.e., age) and psychosocial factors (i.e., occupational stress, burnout) on QoL among working women, and (b) examine the age differences among study variables (young versus mid…
