Only one workout helped older adults lose fat and keep muscle
ScienceDaily reports on a University of the Sunshine Coast trial in Maturitas of 123 healthy older adults, average age 72, who did three supervised sessions of 45 minutes each week for six months. High- and moderate-intensity groups lost more fat than the low-intensity group, but only HIIT retained lean tissue. Researchers called the improvements relatively small, and the scans measured lean tissue, not strength.
Why it matters: Relevant to healthy older adults interested in how exercise intensity relates to body composition, and to the rehabilitation and preventive-care clinicians who work with them.
