Exercise as Medicine

Exercise is an important aspect of overall health and well-being. The benefits of regular physical activity are numerous and extend beyond just physical health to include mental and emotional health as well. Exercise can be considered a form of medicine, as it has been shown to be an effective treatment for a variety of health conditions. In this article, we will explore the concept of exercise as medicine and the evidence supporting its use in the prevention and treatment of various diseases.


The Concept of Exercise as Medicine



Exercise can be considered a form of medicine because it has a positive impact on many different physiological systems in the body. Regular physical activity has been shown to improve cardiovascular health, increase bone density, improve insulin sensitivity, and reduce the risk of certain types of cancer. Exercise has also been shown to have a positive effect on mental health, reducing the risk of depression and anxiety and improving cognitive function.


The concept of exercise as medicine is based on the idea that physical activity can be used as a tool to prevent and treat various health conditions. Exercise can be prescribed in a similar way to medications, with specific dosages and recommendations for duration, intensity, and frequency. By prescribing exercise, healthcare professionals can help patients improve their overall health and well-being.


The Evidence for Exercise as Medicine


There is a significant amount of evidence supporting the use of exercise as medicine. Numerous studies have shown that physical activity can be an effective treatment for a variety of health conditions, including:

  1. Cardiovascular Disease: Exercise has been shown to improve cardiovascular health by reducing blood pressure, improving cholesterol levels, and reducing the risk of heart disease. Regular physical activity can also improve heart function and reduce the risk of heart failure.

  2. Type 2 Diabetes: Exercise has been shown to improve insulin sensitivity, which is important for people with type 2 diabetes. Regular physical activity can also help people with diabetes manage their blood sugar levels and reduce the risk of complications.

  3. Obesity: Exercise is an important tool for weight loss and weight management. Regular physical activity can help people lose weight, reduce body fat, and maintain a healthy weight.

  4. Osteoporosis: Exercise can help improve bone density and reduce the risk of osteoporosis. Weight-bearing exercises, such as walking or jogging, are particularly effective for improving bone health.

  5. Cancer: Exercise has been shown to reduce the risk of certain types of cancer, including breast, colon, and prostate cancer. Regular physical activity can also improve the quality of life for cancer survivors.

  6. Mental Health: Exercise has a positive impact on mental health, reducing the risk of depression and anxiety. Regular physical activity can also improve cognitive function and reduce the risk of dementia.

  7. Chronic Pain: Exercise can be an effective treatment for chronic pain. Regular physical activity can help reduce pain levels and improve overall function for people with chronic pain conditions such as fibromyalgia and osteoarthritis.

Prescribing Exercise as Medicine


Prescribing exercise as medicine involves developing an individualized exercise prescription for each patient. This prescription takes into account the patient's medical history, current health status, and fitness level. The prescription will include recommendations for the type of exercise, duration, intensity, and frequency.


The type of exercise recommended will depend on the patient's health status and fitness level. For example, someone with cardiovascular disease may be prescribed aerobic exercise, such as walking or cycling, while someone with osteoporosis may be prescribed weight-bearing exercises, such as weight lifting or jumping jacks.


The duration and intensity of the exercise prescription will also depend on the patient's health status and fitness level. For example, someone who is new to exercise may start with a shorter duration and lower intensity, while someone who is more fit may be prescribed a longer duration and higher intensity.
