The Claim
Supervised aerobic and resistance exercise performed over 16 weeks in older adults with HIV results in a reduction in fat mass and an increase in lean mass, with no significant change in total body weight or BMI.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In older adults with HIV, 16 weeks of supervised aerobic and resistance exercise reduces body fat and increases muscle mass without changing overall weight or body mass index.
See the scientific wording
Supervised aerobic and resistance exercise for 16 weeks improves body composition in older adults with HIV by reducing fat mass and increasing lean mass, but does not significantly alter total body weight or BMI, indicating that fat loss is offset by muscle gain.
When older adults with HIV do regular aerobic and strength training, their muscles burn more fat for energy and build more muscle tissue, so body fat goes down while muscle goes up — but total weight stays the same because muscle replaces fat.
What the research says
1 studyWhen older adults with HIV did 16 weeks of combined cardio and strength training, they lost fat and gained muscle — so their weight stayed about the same, but their bodies got leaner and stronger.
