For sample adults who had participated in walking in the past 2 weeks (EXWALK), EXWALKMIN reports the average number of minutes respondents had spent walking each time they had engaged in that activity over the past 2 weeks.
After determining that a respondent participated in walking, respondents were first asked, "How many times in the past 2 weeks did you go walking?" (EXWALKNO). They were then asked, "On the average, about how many minutes did you spend walking each time?" EXWALKMIN reports the answer to this last question.
As a follow-up, respondents were asked how much their heart rate or breathing had increased while walking(EXWALKBR).
