The Claim

Sixteen weeks of supervised high-intensity interval training or continuous moderate-intensity exercise, both combined with resistance training, significantly reduce body fat percentage by approximately 3.3% and increase lean mass by 1.2% to 1.7% in sedentary adults aged 50 and older with HIV, with no statistically significant difference between the two exercise intensities.

In plain English

In sedentary adults aged 50 and older with HIV, 16 weeks of supervised high-intensity interval training or continuous moderate-intensity exercise, both combined with resistance training, reduces body fat by about 3.3% and increases lean mass by 1.2% to 1.7%. The two exercise approaches produce similar results.

See the scientific wording

Sixteen weeks of supervised high-intensity interval training or continuous moderate-intensity exercise, both combined with resistance training, significantly reduce body fat percentage by approximately 3.3% and increase lean mass by 1.2% to 1.7% in sedentary adults aged 50 and older with HIV, with no statistically significant difference between the two exercise intensities.

Why this might work

When people do intense or moderate exercise with strength training, their muscles burn more fat for energy and build more muscle tissue because the body senses the physical effort and adjusts how it uses fuel and repairs muscle fibers.

  1. Study: The effects of high-intensity interval training versus continuous moderate-intensity exercise on body composition among older adults with HIV

    For older adults with HIV who haven’t been active, doing either short bursts of intense exercise or steady moderate exercise three times a week for four months — along with strength training — cuts body fat and builds muscle about the same amount, no matter which type you pick.
