Purpose
This study was done to investigate quality of sleep and heart rate variability by the physical activity in high school students.
Methods
A survey that measures physical activity and quality of sleep was distributed to 118 students at Y High School. Heart rate variability was obtained using the LXC3203 heart rate monitor. The data of 105 students were analyzed using descriptive statistics, t-test, x2-test, and ANOVA with Scheffé test.
Results
Boys and students with part-time jobs had significantly higher physical activity. The quality of sleep was significantly high when the students were non-smokers, felt healthy, happy, less stressed, and satisfied with their school lives. Mean heart rate was significantly higher among girls, and standard deviation from normal to normal R-R intervals were high in boys. Physical activity had no significant relationships with quality of sleep and heart rate variability.
Conclusions
Physical activity should be encouraged for high school students, especially for girls. An experimental study with different intensity and time of physical activity is recommended to examine the relationships with quality of sleep and heart rate variability in the future.

PURPOSE
The purpose of this study was to explore maternal physical activity support for preschool children.
METHODS
Survey methodology using a self-administered questionnaire was employed. Mothers with preschool children from a daycare center in Daejeon participated in the study. One hundred and fifty-six questionnaires were analyzed.
RESULTS
Mothers with preschool children showed a moderate level of physical activity support for their children. Significant factors affecting physical activity support of mothers were monthly household income (beta=.417, p=.002), maternal self-efficacy for physical activity support (beta=.231, p=.003), information for physical activity support (beta=.173, p=.022), and experience of education about physical activity support (beta=.237, p=.002). These variables explained 26.4% of the variance in physical activity support (F=7.628, p<.001).
CONCLUSION
To improve maternal support for increasing physical activity of preschool children, maternal education and appropriate information should be provided to improve self-efficacy for physical activity support.
