| Abstract |
This study explores the effects of physical activity on the HRV and stress level among female high school students. We measured the physical activity level of two hundred students with the International Physical Activity Questionnaire. Physical activity was categorized as vigorous, moderate, and walking. We selected twenty students for each category and measured their HRV. By using the IEMBIO, canopy9 and program PASW Statistics18, the collected data calculated the average value of the measurement items and the standard deviation was statistically treated as follows. The results of this study are as follows; 1) There was no difference in BMI among the three groups. 2) There was a little difference of stress among the three groups. 3) There was a little difference in the average heart rate between the three groups on the degree of participation in physical activity. 4) There was no difference in RMSSD between the three groups on the degree of participation in physical activity. 5) There was no difference in TP between the three groups on the degree of participation in physical activity. 6) There was a difference in LF between the three groups on the degree of participation in physical activity. And LF of vigorous physical activity group was higher than walking physical activity group. These results suggest that higher physical activity level is associated with higher heart rate stability, sympathetic nervous activity, and stress resistance. |
