The THINK program will begin with a series of baseline physical assessments comprising both heath and performance-related physical fitness. Participants will also receive a quiz on nutrition and exercise-related information and two surveys regarding nutritional behaviors and physical activity levels. They will be asked to complete one survey on exercise enjoyment and self-confidence. Parents will also be asked to complete a survey each on their child's nutritional habits. This will be done in two experimental and two control YMCA after school programs comprising primarily minority (Hispanic and Black) participants. Testing will again take place midway through the program and at the conclusion of the program nine months later. The control group will not go through the THINK program but will instead go through the traditional SPARK curriculum.
