HIV patients treated with Highly Active AntiRetroviral Therapy (HAART) show significant metabolic symptoms, such as lipodystrophy, dyslipidemia, and insulin resistance. A possible contribution to these symptoms in HIV/HAART is a decrease in mitochondrial function, resulting in a decreased fatty acid oxidation. A combined regime of aerobic and resistance training has been demonstrated to increase lean body mass and reduce overall fat and truncal fat and the levels of triglyceride and LDL cholesterol.
