Translational Health After School Program on Health-Related Knowledge/Behaviors and Exercise Perception

The aim of this study is to examine the effects of a translational health in nutrition and kinesiology (THINK) after school program on physical variables, nutrition and exercise knowledge base/behaviors, and exercise enjoyment and confidence.

Partnering with the YMCA investigators in the Kinesiology and Sport Sciences department at the University of Miami will set up the after-school THINK program offered three afternoons per week for nine months in two experimental and two control schools. The schools will consist of minority elementary school students (predominantly Hispanic and Black) in the South Florida area. The control schools will receive baseline, mid-year and follow-up testing nine months later, but will not go through the THINK program. They will instead go through their standard YMCA after school Sports, Play, and Active Recreation for Kids (SPARK) program.

Two- thirds of American adults are overweight or obese, and that number continues to rise. Thus, it is not surprising that the prevalence of overweight/obesity has more than doubled in school children and tripled in adolescents. Concomitant with the rise in obesity has been a significant decrease in physical fitness levels (1,2). At least one study has shown the youth of today demonstrate lower aerobic fitness levels than their parents (3). Low aerobic fitness levels are most prevalent among Hispanic and Black (non-Hispanic) minority youth. No doubt the increases in TV viewing, computer time and technology have contributed to the increase in sedentary habits and decline in physical activity levels (4).

The THINK program translates fitness and health-related information into knowledge and skills that children can understand and incorporate into their own personal health and lifestyle behaviors. The program is unique in that it combines educational and hands-on clinical experiences with physical activity and exercise. The goal is to promote healthier, more active children of today who demonstrate improved levels of physical fitness, exercise knowledge, and enjoyment of tomorrow.

Each unit in the THINK program has three components: a seminar on the scientific aspects of a health-related theme, clinical experiences related to the theme, and related physical activities performed in the field. The THINK seminars engage students by getting them up and moving, while asking questions that prompt them to think creatively to come up with their own answers. Clinical experiences reinforce the educational themes allowing children to learn more about their bodies, how it functions, and how it adapts through various movement exercises. Finally, games and enjoyable physical activities round out the program contributing to enhanced motor skill development and improved physical fitness levels.

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.

The purpose of the study is to determine whether the THINK program results in improvements in physical fitness, nutrition and exercise knowledge/habits, and exercise enjoyment and self-confidence above that of the control group.
