The Role of Exercise in Integrative Preventive Medicine
Eighty observational association studies and several controlled trials provide strong evidence that exercise, done in appropriate amounts and with appropriate techniques, can dramatically enhance well-being and decrease morbidity and mortality. This chapter summarizes the available evidence so that healthcare providers can write rational prescriptions for physical activity for patients that allow minimal activity for maximum health benefit. In brief, doing four physical activities weekly—(1) any kind, (2) strength building, (3) bone strengthening (jumping), and (4) stamina building—and avoiding prolonged (> 1 hr) inactivity by walking for two minutes every hour—provides maximal morbidity and mortality benefit.
