Interpretive Summary: In this study, we examined how physical activity and fitness changes in girls from 8 to 10 years of age. These girls had either lean parents, a lean and an obese parent, or two obese parents. A longitudinal study was undertaken with annual assessments at 8, 9, and 10 years of age. Fitness was measured by treadmill testing, and physical activity measured by heart rate monitoring and by questionnaire. Sedentary behavior was assessed by questionnaire. Fitness did not change over time, but fitness did differ by groups. Girls with either 1 or 2 obese parents had significantly lower fitness than girls with 2 lean parents. Time spent watching TV during the school year and summer was similar over the study period and between groups. Our data suggest that fitness and physical activity remain fairly constant in girls from 8 to 10 years of age, but girls of obese parents tend to be less fit.
