The effects of a high school walking program, The Robust American Indian
Lifestyle Study (TRAILS), were evaluated by measuring
changes in lipid profile, aerobic capacity, and body composition. The walking program was implemented at Anadarko Public High School in
southwest Oklahoma. Approximately 55% of the school's students are Native
American, 34% are white, and 4% are African American. Ethnically, 7% of the
students are Hispanic or Latino.
The intervention consisted of daily (Monday through Friday) self-paced
walking for 35 to 40 minutes for 11 weeks. Pre- and post-intervention
assessments of non-fasting lipid profile, non-fasting plasma glucose, aerobic
capacity, and body composition were performed.
Twenty-five students completed the pre- and post-intervention
assessments. The mean age of the students was 16.7 years (± 1.4). Sixty percent
of the students were of normal weight, 4% were at risk for overweight, and
36% were overweight. The mean miles walked was 37.6 (± 10.7). Using paired
t-tests, statistically significant improvements were seen in total
cholesterol (174.8 to 149.4 mg/dL, P < .001); low-density
lipoprotein cholesterol (106.4 to 85.1 mg/dL, P < .001); non-high-density lipoprotein
cholesterol, calculated by subtracting high-density lipoprotein cholesterol
from total cholesterol (128.5
to 105.9 mg/dL, P < .001); and non-fasting plasma glucose (103.2 to
82.4 mg/dL, P < .001).
A school-based walking program may have a positive impact on lipids and
non-fasting plasma glucose.
