Description

For sample adults who had participated in aerobics or aerobic dancing in the past 2 weeks (EXAEROB), EXAEROBBR reports whether respondents usually experienced a small, moderate, or large increase, or no increase at all in their heart rate or breathing while doing aerobics or aerobic dancing.

After determining that a respondent participated in aerobics or aerobic dancing, respondents were first asked, "How many times in the past 2 weeks did you do aerobics or aerobic dancing?" (EXAEROBNO). They were then asked, "On the average, about how many minutes did you spend (doing) aerobics or aerobic dancing each time?" (EXAEROBMIN). Finally, to obtain information for EXAEROBBR, respondents were asked, "What usually happened to your heart rate or breathing when you did aerobics or aerobic dancing? Did you have a small, moderate, or large increase, or no increase at all in your heart rate or breathing?"
