- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This looked back at real patients, but it has not been proven in a trial.
The short version
In one look back at past patients, those who exercised after diagnosis tended to be in better shape when the tumor returned.
What was studied. Researchers looked back at records from 201 people with glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary who were diagnosed between 2010 and 2023. Of these, 25 took part in a planned exercise program after diagnosis, and the team compared them with those who did not.
What they found. When the tumor came back, people in the exercise program had smaller tumors. They were also better able to do daily tasks. They lost less muscle and gained less fat inside and under the skin than people who did not exercise. The exercise program by itself was not clearly tied to living longer once other factors were counted.
What this means, and what it doesn't
What it could mean: This hints that staying active after a glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary diagnosis may help keep your body stronger. It may be worth asking your care team if a safe exercise plan is right for you.
What it doesn't mean: This does not prove that exercise shrinks tumors or helps people live longer. The researchers only looked back at past records, and the group that exercised was small. They say new studies that assign people to exercise or not are needed. This is not a cure, and it does not replace your treatment.
