Outline of the pilot study procedure from baseline to 12-month measures. The Smart Heart Trial included three assessments and spanned 12 months. The physical, metabolic, cardiovascular, and body composition outcome measures were taken for each subject upon study entry at baseline and at follow-up after 6 and 12 months.
