Oxygen, Exercise, Weight in Women
Do African-American and Caucasian overweight
women differ in oxygen consumption during fixed periods of exercise?
Exercise & Weight Loss Study Aim
To examine whether there are ethnic differences in oxygen consumption
during fixed periods of exercise.
Exercise & Weight Loss Study Subjects
Twenty-seven African-American and 120 Caucasian overweight adult women
prior to initiating a weight loss program.
Exercise & Weight Loss Study Measurements
Measurement of oxygen consumption occurred during four stages of a graded
exercise test, with body composition assessed by dual-energy X-ray absorptiometry.
Exercise & Weight Loss Study Results
There were no significant differences between overweight African-American
and Caucasian women for absolute oxygen consumption or oxygen consumption
adjusted for either body weight or fat-free mass across four levels of
a submaximal graded exercise test.
Exercise & Weight Loss Study Conclusion
The results from this study suggest that African-American and Caucasian
women do not differ in energy expenditure during fixed workloads of exercise,
suggesting that this may not contribute to differences in energy balance
and body weight regulation between women in these two ethnic groups.
