Persons over 35 years old have an increased prevalence of risk factors. Careful medical examinations, even in a fit military population, are needed before initiating intensive physical train ing regimens. Risk factor profiling, which synthesizes major risk factors into a composite score, is a beneficial procedure by which to evaluate individuals. Training programs should be based on several considerations: (1) the individual's age and physical condition; (2) his body composition; (3) his risk factor profile; (4) his preference and physical ability for activity; and (5) the available facilities and climatic conditions. Exercise should enhance work capacity and serve as a preventive mea sure for coronary heart disease. The most efficient types of exercise to meet these ends are activities that involve the large muscles in continuous activity for 20 to 30 min daily, including warm-up and cool-down periods.
