Background:
Understanding the physical activity patterns of youth is important for the implementation and evaluation of programming and interventions designed to change behavior. To date, little is known about the objectively measured physical activity patterns of Native American youth. Therefore, the purpose of the study was to examine the step counts of Navajo youth during weekdays, weekend days, and physical education classes.
Methods:
Participants included 63 high school students (mean age = 15.14 ± 1.37 years). Youth wore a pedometer (Walk-4-Life 2505) for seven consecutive days. Means and standard deviations were calculated for weekdays, weekend days, and physical education.
Results:
Boys averaged 11,078 ± 4400 steps/weekday compared to 6493 ± 5651 on weekend days. Girls averaged 7567 ± 5614 on weekdays compared to 7589 ± 7712 on weekend days. Both boys (20 %) and girls (26 %) accumulated a large percentage of their weekday step counts from physical education classes.
Conclusions:
Findings highlight the importance of additional physical activity opportunities in the community. Youth are falling well short of recommended levels of physical activity with physical education being an important source of physical activity.

Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
