Overall, all items had at least fair agreement for all participants, males and females with frequency of physical activity participation in the evenings (6-9 pm) and very active participation in Physical Education being the most stable items for all participants.
The weekly frequency of physical activity in the various domains (physical education at school, leisure time physical activity, active commuting to and from school, and LPA) was also estimated for the entire population and by gender.
To date, no information is available on the optimal frequency of physical activity on cognitive functioning in children.
The purpose of the study was to identify the factors associated with older adults' frequency of physical activity.
We computed the mean across summer and winter in all three settings and we selected the exercise intensity and setting with the maximum value to represent the highest frequency of physical activity across all domains.
We also examined repeatability of women's responses to questions on frequency of physical activity over time.
Boys had a higher frequency of physical activity and girls a higher frequency of skipping meals.
The type, intensity and frequency of physical activity for effective stress control remains unclear.
Mean BMI decreased and mean alcohol consumption increased with increasing frequency of physical activity.
We also hypothesized that boys would report a higher frequency of physical activity than girls, and that the frequency of physical activity would decrease with age in both sexes.
No significant trends in the risk of ankle or of wrist fracture were observed by women's frequency of physical activity.
