Exercise in Insulin-Resistant Minority Adolescents

An Exercise Intervention in Insulin-Resistant Minority Adolescents

• Status: Completed
• Phase: —
• Study type: Observational
• Enrollment: 40 (estimated)
• Sponsor: Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) · NIH
• Sex: All
• Age: 14 Years – 18 Years
• Healthy volunteers: Not accepted

Summary

Insulin resistance, often accompanied by obesity, plays a major role in the development of type 2 diabetes. This phenomenon may be related with the fact that American adolescents are now becoming less physically active in early puberty, explaining the largely pubertal and post-pubertal onset of type 2 diabetes in adolescence. Although regular physical activity has been suggested to attenuate obesity and prevent type 2 diabetes in high-risk children and adolescents, the magnitude of exercise training-induced improvement in the risk factors for type 2 diabetes has been only recently studied in adults and studied very little in pediatric populations. It is clear that exercise, diet, and genetics all contribute to the development of type 2 diabetes in children. However, the few studies that have been done to dissect the relative contributions of these three risk factors have generally used only lipid profiles as the end point. There have been a number of recent advances in our understanding of the molecular basis of type 2 diabetes, particularly, with regards to insulin regulatory pathways modulated by exercise within muscle tissue.
