Review on the Formulation, Existing Problems, and Practical Effects of Fitness Exercise Prescriptions for People With Intellectual Disabilities.

Compared with normal people, patients with intellectual disability have poor cardiopulmonary and muscle fitness levels, and their daily physical activity generally cannot reach the "guideline-recommended amount," which increases the risk of obesity and cardiovascular disease in this group.

The results show that the design idea of aerobic fitness exercise prescription for patients with intellectual impairment follows the six-element paradigm, but the insufficient recommended amount of each element is a common problem.
