摘要

Data from the 1999–2004 National Health and Nutrition Examination Survey were used to describe the distributionnof cardiorespiratory fitness and its association with obesity and leisure-time physical activity (LTPA) fornadults 20–49 years of age without physical limitations or indications of cardiovascular disease. A sample of 7,437nadults aged 20–49 years were examined at a mobile examination center. Of 4,860 eligible for a submaximalntreadmill test, 3,250 completed the test and were included in the analysis. The mean maximal oxygen uptaken(_VO2max) was estimated as 44.5, 42.8, and 42.2 mL/kg/minute for men 20–29, 30–39, and 40–49 years of age,nrespectively. For women, it was 36.5, 35.4, and 34.4 mL/kg/minute for the corresponding age groups. Non-nHispanic black women had lower fitness levels than did non-Hispanic white and Mexican-American women.nRegardless of gender or race/ethnicity, people who were obese had a significantly lower estimated maximalnoxygen uptake than did nonobese adults. Furthermore, a positive association between fitness level and LTPAnparticipation was observed for both men and women. These results can be used to track future populationnassessments and to evaluate interventions. The differences in fitness status among population subgroups andnby obesity status or LTPA can also be used to develop health policies and targeted educational campaigns.
