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