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 older, those who engaged in either exercise regimen for 16 weeks showed significant reductions in body fat and increases in lean muscle mass. This is particularly important for older adults who want to maintain a healthy weight and muscle strength as they age.

For people living with HIV, maintaining a healthy body composition is crucial for overall health and longevity. The study showed that participants experienced a decrease in fat percentage of about 3.3% and an increase in lean mass of 1.7% after following either exercise program. This can lead to better energy levels, improved mobility, and a lower risk of chronic diseases, which are essential for aging well.

The research is based on a small human trial, with 95 participants, and while the results are promising, they are not yet definitive. Both HIIT and CME combined with resistance training showed benefits, but there were no significant differences between the two exercise types. This suggests that older adults can choose either approach based on their preferences and fitness levels.

If you’re looking to improve your body composition, consider incorporating either HIIT or CME into your routine, along with resistance training. Start slowly and gradually increase intensity to ensure safety and effectiveness. Always consult with a healthcare provider before beginning any new exercise program, especially if you have underlying health conditions.
