Exercise prescription--North American experience.
  1. R. J. Shephard

    Abstract

    The principles of exercise prescription are reviewed with respect to North American experience. The required regimen must be safe, therapeutically effective, and ensure a high rate of compliance. Precautions to increase the safety of exercise are discussed. Cardiac emergencies are sufficiently rare events (less than 1 in 200,000 hours even in post-coronary classes) that the need for immediate medical supervision of a well-designed programme can be questioned. The prime determinant of the response to training is the intensity of effort relative to the individual's initial fitness. Post-coronary patients often have a great potential for training due to their previous inactivity, but this will not be realised if the prescribed exercise is of insufficient intensity. Exercise programmes are plagued by a high 'drop-out' rate; 50% of normal middle-aged volunteers are lost in 6 months, and even with post-coronary programmes losses can be 60--70% over 4 years. Simple suggestions are made for improving compliance with the required exercise prescription.
