For sample adults who had participated in biking in the past 2 weeks (EXBIKE), EXBIKENO reports the number of times the respondent had participated in biking over those 2 weeks.

After the interviewer determined that a respondent participated in biking, respondents were asked, "How many times in the past 2 weeks did you bike?"

Related Variables 

Respondents were also asked how many minutes on average they had spent biking each time during the past 2 weeks (EXBIKEMIN) and how much their heart rate or breathing had increased while biking (EXBIKEBR).


Apart from universe changes, EXBIKENO is fully comparable across all years.
