Medical Professionals Propose Prescribing Physical Exercise Over General Lifestyle Advice
Medical professionals are moving to treat physical activity as a core medical intervention rather than a broad lifestyle recommendation. Carl Zhou and Nicholas Fabiano at the University of Ottawa, alongside Stanley Wong at the University of Toronto, outlined this shift in an article published in the journal Brain Health.
The researchers argue that maintaining a healthy brain requires sustaining cognitive, emotional, behavioral, and social functions throughout life. Under the proposed model, doctors would move beyond general suggestions and issue specific exercise prescriptions.
We tend to consider the exercise as a generalist advice about the lifestyle,
Dr. Zhou stated. The evidence we have analyzed supports a more specific approach: a prescription that specifies the type of activity, frequency, intensity, duration, safety considerations, and a monitoring plan, just as we would do with a medication.
When individuals move skeletal muscles, the tissue releases myokines, which are molecules that interact with the body to modify metabolic, inflammatory, and neural signals. Aerobic exercise also increases circulating blood flow, which delivers nutrients and clears cellular waste. Research indicates that physical activity increases blood flow and activity in the hippocampus, a brain region vital for memory consolidation.
The World Health Organization recommends physical activity to reduce the risk of all types of dementia, including Alzheimer’s disease. The organization advises at least 75 minutes of moderate-intensity activity per week to yield measurable public health benefits.
Build sustainable exercise habits through small daily successes
While the World Health Organization baseline sits at 75 minutes, broader guidelines recommend between 150 and 300 minutes of moderate-intensity activity, or 75 to 150 minutes of vigorous activity weekly, combined with two days of strength training.
The starting point does not have to be impressive,
Dr. Fabiano stated. It has to be feasible. Repeated small successes foster self-efficacy and create habits, and that is what generates the conditions necessary to maintain activity sustainably.
Patients struggling with a 15-minute daily routine can begin with a 5-minute walk or exercises performed while seated. Healthcare providers in primary care and physiotherapy could design personalized regimens for patients, utilizing community centers and support groups to improve access.
This structured approach aims to increase energy, self-sufficiency, sleep quality, and overall life satisfaction for patients who maintain the routine.
Frequently Asked Questions About Exercise Prescriptions
What specific details would an exercise prescription include?
An exercise prescription details the exact type of physical activity, weekly frequency, workout intensity, session duration, safety considerations, and a formal monitoring plan administered by healthcare professionals.
How much weekly physical activity does the World Health Organization recommend?
The World Health Organization recommends at least 75 minutes of moderate-intensity activity per week to observe measurable health benefits, with broader guidelines ranging between 150 and 300 minutes of moderate activity weekly.
Which researchers proposed changing exercise from advice to treatment?
Carl Zhou and Nicholas Fabiano from the University of Ottawa, alongside Stanley Wong from the University of Toronto, proposed the shift in the journal Brain Health.
