The Roles of Sex and Minority Status in Children's Motivation and Psychomotor Learning.

In this study, we had two inter-related goals: (a) to examine sex and minority status differences on children's motivation for physical education (PE; i.e., their expectancy beliefs, subjective task values, and situational interest) and their psychomotor learning outcomes (i.e., motor competence, cardiorespiratory fitness, and in-class physical activity); and (b) to examine the relationships between children's motivation and their psychomotor learning outcomes while testing the moderation effects of sex and minority status. We recruited 195 fourth and fifth-grade students (101 boys; 94 girls; Mage = 10.7, SD = 0.7 years) from three elementary schools in North Texas. Using multivariate analysis of variance, we identified a significant sex difference that favored boys in motivation and psychomotor learning outcomes, with no significant minority status difference in relation to these variables. Regression analysis revealed that children's expectancy beliefs were significantly associated with both motor competence (R2 = 11%) and cardiorespiratory fitness (R2 = 16%), while both situational interest and sex were associated with in-class physical activity (R2 = 18%). Thus, improving children's expectancy beliefs may be a means of enhancing psychomotor learning outcomes in PE, especially for girls. Enhancing children's beliefs in their own ability and offering diversified PE content so as to generate greater interest may facilitate psychomotor learning.

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, moderate, and vigorous PA was captured by accelerometers. The FITNESSGRAM battery was used to measure children's HRF, including body composition, cardiorespiratory fitness, and muscular fitness. Structural equation models were used to evaluate two proposed models (model-1 = FMS¼HRF¼PA; model-2 = PA¼HRF¼FMS). Both locomotor and ball skills were associated with all components of HRF (p < 0.01), but not PA. The SEM analyses supported associations between FMS, HRF and PA, with sound goodness-of-fit indices: (1) model-1: CFI = 0.95; RMSEA = 0.072; and (2) model-2: CFI = 0.95; RMSEA = 0.071, respectively. The relationship between FMS and PA was fully mediated by the HRF in both directions. The behavioral mechanism (e.g., maintaining appropriate levels of HRF) provides meaningful insights to understand the obesity trajectory during middle childhood.

School-Based Sedentary Behavior, Physical Activity, and Health-Related Outcomes among Hispanic Children in the United States: A Cross-Sectional Study.

The main purpose of this study was to examine the relationships between school-based sedentary behavior, physical activity, and health-related outcomes, including cardiorespiratory fitness, weight status, and health-related quality of life (HRQOL) among Hispanic children. The participants were 374 children (192 boys, 182 girls; Mage = 9.64) recruited from four elementary schools from 3rd grade through to 5th grade. Sedentary behavior and physical activity behaviors (light physical activity [LPA] and moderate-to-vigorous physical activity (MVPA)) during school were measured by accelerometers. Cardiorespiratory fitness and weight status were measured using the FITNESSGRAM®, while HRQOL was measured using the PedsQL 4.0TM Spanish version, a validated questionnaire. Sedentary behavior was negatively correlated with cardiorespiratory fitness and HRQOL but positively associated with weight status. MVPA was positively correlated with cardiorespiratory fitness and HRQOL, but negatively associated with weight status and sedentary behavior. Multiple regressions demonstrated that sedentary behavior significantly predicted cardiorespiratory fitness and weight status, whereas MVPA significantly predicted HRQOL. With the current public health priority aiming to reduce health disparities in minority populations, the findings of this study provide important insights. Educators, health care providers, or other professionals working with Hispanic children are encouraged to focus on reducing sedentary behavior and promoting physical activity to improve their health-related outcomes.

The direct and indirect effects of motor competence on adolescents' mental health through health-related physical fitness.

Mental health is an important public health issue and up to one in five youth experience mental health problems. The primary purpose of this study was to examine the relationship among motor competence, health-related physical fitness and mental health outcomes in adolescents. A secondary goal was to test the direct and indirect effects of motor competence on adolescents' mental health through health-related physical fitness. Participants were 279 adolescents (Mage = 12.49, SD = 0.89) recruited in the south-west region of the US Motor competence including volleyball, soccer, and ultimate Frisbee, were assessed using PE Metrics™. FITNESSGRAM® test battery was used to assess health-related physical fitness components. Students completed a survey measuring their depressive symptoms and health-related quality of life. Motor competence was significantly associated with components of health-related physical fitness (r ranged from -0.15 to 0.38). The robust fit of the model supports the significant indirect effect of motor competence on mental health outcomes through health-related physical fitness (χ2/df = 39.92/25; CFI = 0.97; RMSEA = 0.046; 90% CI [0.02, 0.07]). The hypothesized conceptual model tested in this study provides insights into the potential interaction of motor competence and health-related physical fitness with adolescents' mental health.

The roles of physical activity and sedentary behavior on Hispanic children's mental health: a motor skill perspective.

PURPOSE: Motor competence (MC) has been recognized as the foundation for life-time moderate-to-vigorous physical activity (MVPA) as well as an influential factor in reducing sedentary behavior during childhood. Guided by Blair et al.'s health model, the purpose of this study was to examine the behavioral mechanism of mental health including physical, psychosocial, and cognitive health among Hispanic children related to MC and MVPA. METHODS: A prospective research design was used with two-wave assessments across one academic year. A total of 141 Hispanic kindergarteners (Meanage = 5.37, SD = 0.48) were recruited in Texas. Nearly all (94.3%) of the participants were from low-income families based on the Income Eligibility Guidelines. The study was approved by the University Research Review Board, and informed consent was obtained from parents/guardians prior to starting the study. RESULTS: Multiple regressions indicated that manipulative skill was a significant predictor of physical and psychosocial health (ß = 0.21, ß = 0.26, p < 0.05, respectively) and locomotor skill served as a significant predictor for cognitive health (ß = 0.22, p < 0.01), after controlling for BMI. Bootstrapping analyses supported the statistical significance of indirect effects of MC on mental health outcomes through MVPA (95% CI [0.031, 0.119]) and sedentary behavior (95% CI [0.054, 0.235]), respectively. CONCLUSION: The results suggest that skill-based activities/games, with instructions, should be encouraged during school-based physical activity and health promotion programs in childhood education. Better understanding of the early effects of MC may contribute to designing strategies to promote Hispanic children's well-being.
