Background:
Literature consistently shows dearth of published data from developing countries on effect of exercise on HIV infected persons.
Objective:
The study was aimed at determining effect of aerobic exercise on CD4 cell counts and lipid profile of HIV infected persons in Northeastern Nigeria.
Methods:
Sample of convenience was employed to enroll volunteer and willing 91 HIV infected persons attending antiretroviral clinic at a tertiary hospital in Northeastern Nigeria. Eighty two met the inclusion criteria and participated in the study. Participants were randomly assigned to experimental and control groups. Baseline values of the variables were determined. Experimental group participated in moderate intensity treadmill aerobic exercise for 12 weeks. Control group participated in weekly lectures on nutrition, adherence to therapy among others. At the end, the study recorded 22% attrition rate, leaving 32 participants in each group (64 participants in both). After the 12 weeks, the variables were re-evaluated. Descriptive statistic summarized the socio-demographic characteristics of the participants. Paired and unpaired Student t-tests analyzed the significant difference in mean values of the variables.
Results:
Mean ages in years of the 64 participants, the control and experimental groups were 39.57 ± 10.13, 39.38 ± 10.03 and 40.84 ± 10.05 respectively. There was significant improvement (p < 0.05) in the variables between pre- and post-tests in the experimental group. In the control group, there was either no significant change (p > 0.05) or significant deterioration (p < 0.05) in lipid profile between pre- and post-tests, while in CD4 cell counts, significant improvement was observed. Significant difference (p < 0.05) existed in the variables at the end of the study between both groups.
Conclusion:
CD4 cell counts and lipid profile of HIV infected persons who participated in the 12 weeks moderate intensity treadmill aerobic exercise significantly improved. Proper nutrition and adherence to antiretroviral therapy may enhance immune function in HIV population.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

01:26Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
