This study examines the relationship between physical activity in sport and feelings of well-being, testing alternative interpretations of the relationship between these two variables. It was expected that there would be positive relationships between physical activity on the one hand and physical fitness, feelings of well-being, social interaction in the sport and exercise environment, and socioeconomic status on the other hand. It was also expected that physical fitness, social interaction, and socioeconomic status would be positively related to psychological well-being. Further, it was expected that any positive zero-order relationship of physical activity and well-being would be at least in part a result of the conjoint effects of the other variables. The analyses were conducted separately for the male and female subsamples of a large survey study of Canadian adults. The results, after controls, show a modest positive relationship of physical activity and well-being for males but no such relationship for females. The predicted independent effects of the control factors obtained for both males and females. Interpretations of the results are discussed.

Objective. The purpose of this study was to examine the relationship of grit as a construct representing perseverance to overcoming barriers and the total number of school absences to academic performance (AP) while controlling for sociodemographics, fitness (i.e., PACER), and Body Mass Index (BMI). Methods. Adolescents (N = 397, SD = 1.85; 80.9% females; 77.1% Hispanic) from an urban, minority-majority city in the Southern United States completed the FitnessGram® assessment of physical fitness (e.g., aerobic capacity and Body Mass Index (BMI)) and the valid and reliable short grit survey. The schools provided sociodemographics, attendance, and AP data for the adolescents. Results. Adolescents with higher grit scores (rs=0.21, P < 0.001) and less total absences (rs=-0.35, P < 0.001) performed better on AP. Hierarchical multiple regression indicated that grit and absences were associated with AP (β = 0.13, P < 0.01 and β = −0.35, P < 0.001, resp.). Conclusions. Grit and a total number of absences are significant contributors to academic success, particularly among Hispanic adolescents. Further, grit and school attendance may serve as a better measure of protective factors over proximal health measures of cardiovascular health and BMI.

The relationship of classroom teachers’ leisure time physical activity and their conduct of physical education classes was investigated. Eighteen 4th- and 5th-grade teachers reported on their leisure physical activity and had their physical education classes observed systematically during 4 consecutive semesters. Correlational analyses confirmed that more active teachers taught physical education differently from those that were less active. Teachers who were more active provided students with increased physical fitness activities, and the teachers themselves spent more time promoting physical fitness during lessons. The study provides some support for the hypothesis that physically active teachers provide higher quality physical education.

The present study examined the associations of physical fitness and motorcompetence with P3 and alpha desynchronization (ERD), two neuroelectric indices ofbrain development underlying controlled attention, in 4-6 year-old preschool children. Allparticipants completed physical fitness and motor competence test batteries and anauditory oddball task while electroencephalogram (EEG) was recorded. Resultsrevealed that increased muscular power, muscular endurance, physical fitness, andmotor competence were associated better attentional task performance. Analysis onneuroelectric indices showed that muscular endurance was related to increased P3amplitude, while the increases in physical fitness and motor competence wereassociated with greater upper alpha (10-12 Hz) ERD following the stimulus evaluationand response selection. Further, the negative associations of physical fitness and motorcompetence with task response time were mediated by the upper alpha ERD. Thesefindings highlight the importance of early childhood motor competence and physicalfitness, especially muscular endurance, to neurocognitive function.
