The delineation between strenuous and light was whether the activity resulted in breathlessness and sweating or not.
Level of strenuous and light leisure-time physical activity was graded according to hours of activity resulting and not resulting in perspiration or breathlessness during an average week.
Strenuous and light activity were assessed on a five-point scale: 1 = no days, 2 = 1 or 2 days, 3 = 3 to 5 days, 4 = 6 to 8 days and 5 = 9 days or more.
In this questionnaire, participants are asked to report the average weekly frequency and duration with which they engaged in strenuous, moderate, and light exercise over the past month.
19 Separate hours per week variables were calculated for strenuous, moderate and light PA by multiplying the number of hours spent per week by the portion of the year in which they engaged in activity at those intensities.
Assisted by a trained interviewer, participants estimated the average hours per week and the average number of months during the past year they spent in exercise, sport or work activities of strenuous, moderate and light intensities.
