Obesity is one of the most common non-communicable chronic diseases in childhood with a tendency to extend into adulthood.  Physical activity is essential to increasing HDL-cholesterol (HDL-C). It is more difficult for overweight individuals to realize this benefit. These difficulties can be minimized with aquatic exercise. The aim of this study was to investigate the effects of 12 weeks of water-based exercises on HDL-cholesterol in overweight and obese adolescents.

Conclusion & Implications:  Our data demonstrates the beneficial effects of an interval training exercise program on BMI and HDL-C. Through more enjoyable activities, such as water-based exercises, we can provide long-term continuity, favoring the improvement of the cardiovascular risk profile in this population. Aquatic exercise would be a good alternative to reduce the risks associated with overweight and obesity considerations in adolescents.
