Since the outbreak of the HIV pandemic, more than 30 million people have died from AIDS in the last 40 years; thus the human immunodeficiency virus (HIV) and the acquired immunodeficiency syndrome (AIDS) continue to spread throughout the world. The effectiveness of retrovirals with modern drug combinations for the treatment of HIV/AIDS allows many people to improve their life expectancy. Although retrovirals have achieved a better quality of life among patients suffering from the disease, the disease can result in a number of adverse physical and physiological effects. In many cases, patients infected with the HIV/AIDS virus could be treated with other alternative forms adjunct to retroviral treatment such as physical exercises. The purpose of this research is to determine the effect of positive emotions generated after physical activity in various parks in the city of Lima as a complementary therapy in HIV/AIDS patients. For this, 25 patients divided into two groups were studied: a control of 10 people who was not under the exercise program, and a second group of 15 people who underwent an exercise regimen for one year. The experiments were analyzed using a Likert-type survey that measured participants' positive emotions and CD4 T-cell count. The results showed that people under the exercise regimen had a higher assessment of both positive emotions and CD4 T cells.
