Abstract

We tested the hypothesis that the age-related decline in maximal aerobic capacity, as measured by maximal oxygen uptake ((V) over dot O-2 (max)), is greater in Hispanic than in Caucasian women. We studied 146 healthy sedentary women aged 20-75 yr: 53 Hispanic (primarily of Mexican descent) and 93 Caucasian (non-Hispanic white). The groups did not differ in mean age, body mass, percent body fat, estimated physical activity-related energy expenditure, or education-based socioeconomic status (SES). During maximal exercise, respiratory exchange ratio, rating of perceived exertion, and percent predicted maximal heart rate were similar across age and ethnicity, suggestingequivalent maximum voluntary efforts in all subjects. (V) over dot O-2 (max) (ml . kg(-1) . min(-1)) was inversely related to age (P < 0.01) in Caucasian (r = -0.68) and Hispanic (r = -0.61) women. The absolute rate of decline in (V) over dot O-2 (max) with age was the same in the two groups (-0.31ml . kg(-1) . min(-1) . yr(-1)). The relative rate of decline (% from age 25 yr) also was similar in the Caucasian (-9.0%) and Hispanic (-9.2%) women. When subjects of all ages were pooled, mean levels of (V) over dot O-2 (max) were similar in the two groups (<similar to>28 ml . kg(-1) . min(-1)). These results, the first to our knowledge in Hispanics, indicate that mean levels of (V) over dot O-2 (max), as well as the rate of decline in (V) over dot O-2 (max) with age, are similar in healthy sedentary Hispanic and Caucasian women of similar SES. Thus it does not appear that Hispanic ethnicity per se modulates maximal aerobic capacity in this population.
