Addressing days, hours and minutes per week in vigorous PA, moderate activity, walking and sitting during a weekday.
The validity for single IPAQ questions within "moderate activity", "walking" (days per week) and "sitting" was poor.
In the study with influenza virus, both vigorous activity as well as moderate activity (walking) appeared to be beneficial.
Higher levels of physical exercise at least 1 h a day of moderate activity (walking) or 30 min a day of more vigorous exercise (jogging)—can be required to obtain effective long-term weight loss.
These questions from IPAQ we also calculated METs and hours per week in vigorous and moderate activities, walking and sitting, as described by Craig et al. [ 1] and already mentioned.
We used the International Physical Activity Questionnaire (IPAQ), which assesses the duration and frequency of vigorous and moderate physical activity, walking and sitting over the last 7 days.
Measures physical activity across several domains, with primary outcome measures including walking in general, moderate activity, vigorous activity, walking for transport, and cycling for transport.
Primary outcome measures of physical activity include time (minutes/week) spent in walking, walking + moderate activity, vigorous activity, walking for transport, and cycling for transport, as well as an overall measure of activity expenditure (MET.minutes/week).
These values (vigorous activity, moderate activity, and walking) were used to calculate the PA levels, as specified in the official IPAQ instruction manual.
The 2002 Eurobarometer survey on physical activity, the most recent survey of the European population of its kind, included questions on the frequency and duration of vigorous activity, moderate activity, and walking [ 47].
Physical activity intensities were classified as follows: lying down and sitting as sedentary, standing as light physical activity, walking as moderate physical activity, and very active as vigorous physical activity [ 23].
