Purpose
The study is a behavioral clinical trial of aerobic exercise to determine dose-response effects on risk for type 2 diabetes, fatness, fitness, blood cholesterol levels, and other cardiovascular risk factors in overweight elementary schoolchildren.
The hypothesis is that the more exercise a child does, the more benefit he or she will gain in reducing the risk of diabetes and other cardiovascular diseases.
An ancillary study examined effects on cognition and achievement.

| Arms | Assigned Interventions |
|---|---|
|
No Intervention: Control
Children were not provided with an after-school exercise intervention. They were free to do their usual activities. Families were offered a monthly healthy lifestyle class.
|
|
|
Experimental: Low Dose
This group was assigned to receive a 20 min/day aerobic exercise program offered 5 days/week after school. Families were offered a monthly healthy lifestyle class.
|
Behavioral: Aerobic exercise program
Vigorous intermittent physical activity in group format conducted in research gymnasium after school by research staff. Heart rate monitors documented each child's average heart rate on a daily basis. Small incentives were offered for achieving goal of >150 bpm average HR each day and attending at least 80% of sessions (4 days/week).

|
Experimental: High dose
This group was assigned to receive a 40 min/day aerobic exercise program offered 5 days/week after school. Families were offered a monthly healthy lifestyle class.

Detailed Description:
The study is a behavioral clinical trial of aerobic exercise to determine dose-response effects on insulin response to the oral glucose tolerance test, body composition, fitness, lipid profile, inflammation and other metabolic syndrome components in overweight elementary schoolchildren.
Blinded psychological assessments of cognition and achievement were obtained.
