Researchers found that both high-intensity interval training (HIIT) and continuous moderate-intensity exercise (CME) can effectively improve body composition in older adults living with HIV. In a study involving 95 participants aged 50 and above, those who engaged in either form of exercise for 16 weeks saw reductions in body fat and increases in lean muscle mass. This is particularly important for older adults, as maintaining a healthy body composition can support overall health, mobility, and quality of life as they age.

For people over 50, especially those with HIV, the findings suggest that incorporating regular exercise can lead to meaningful changes in body fat and muscle strength. Both exercise types resulted in a similar decrease in body fat percentage of about 3.3%, while HIIT participants gained slightly more lean mass compared to those doing CME. This means that regardless of the intensity, older adults can benefit from exercise to help manage their body composition, which is crucial for maintaining energy levels and reducing health risks.

The study is based on a well-structured trial with 95 participants, providing strong evidence that both HIIT and CME are effective strategies for improving body composition among older adults with HIV. However, it’s important to note that while both exercise types showed benefits, the researchers did not find significant differences between the two methods. This suggests that individuals can choose the type of exercise they enjoy most, knowing they can still achieve positive results.

If you’re over 50 and looking to improve your body composition, consider adding a mix of HIIT or moderate-intensity exercise along with resistance training to your routine. Always consult a healthcare provider before starting a new exercise program, especially if you have underlying health conditions.
