The information and the fitness program outlined are based on experience and research conducted at the Nadezha Health Club in Smolensk, Russia. Major risk factors for cardiovascular disease are discussed, as well as how development of coronary disease can be attenuated or arrested by a prolonged routine of jogging. The effects of fitness running are also outlined in relation to certain diseases and conditions: diseases of the blood vessels of the lower extremities, neurasthenia, gastro-intestinal disease, diabetes, and obesity. A section is also included on running and injuries. The risk factors discussed include: high serum cholesterol, diastolic hypertension, obesity, smoking, unfavorable heredity, insufficient motor activity, and excessive nutrition high in calories. The fundamentals of training which should be applied to fitness running focus on three principles: repetition, incremental improvement, and individualization. Instruction in the basics of fitness running as well as the stages of training vary according to the health, conditioning, and age of participants. Correct planning of weekly and monthly workouts is essential to achieve health benefits. Postexercise recovery should be worked into the routine: a pattern of alternating workouts with rest days.
