Articles authored or co-authored by Walter M. Bortz II, MD:

"On Longevity: Increase Your Bore," Diabetes Wellness Letter," Vol. 1, No. 1. Most heart problems are actually blocked-artery problems. Research has shown that aerobic activity can greatly increase the diameter of arteries when stimulated by exercise. Thus, many heart problems, as well as diabetic complications associated with blockage of the small vessels, could be averted through exercise.

"Predictability of Weight Loss," Journal of the American Medical Association, Volume 204, pp 101-105. This article takes the mystery of weight loss, and demonstrates that one can predict with great accuracy how much weight one will lose each day. Weight loss is a process that is susceptible to logical and reasonable precise explanation. Since a pound of fat stores 3,500 calories, once one's daily basal metabolic requirements are calculated, one can predict weight loss or gain based on caloric intake.

"Running as Armor," Marathon and Beyond, Volume 10, Issue 10, pp 60-65. A fit lifestyle helps to modulate the aging process. Dr. Walter Bortz relates how his state of fitness from running several times a week helped insure his rapid recovery from an accident when a tree fell on him, punctured his lung and broke his ribs. Running and other vigorous aerobic activities helps prevent cardiovascular disease, musculoskeletal frailty, metabolic instability, while boosting the immune system, helping to prevent depression, and helping to prevent premature aging.

"A Conceptual Framework of Frailty: A Review," Journal of Gerontology: MEDICAL SCIENCES, Vol. 57A, No. 5, M283-M288. Does growing older necessarily mean growing more frail? This article defines frailty as a set of body-wide linked deteriorations, and then demonstrates that frailty is largely separable from the process of aging. As such, frailty can be prevented and even reversed by active intervention.

"Physical Fitness, Aging, and Sexuality," Palo Alto Medical Foundation, WIMP, Volume 170, No. 3. Sexuality is a major quality of life issue, even into advanced age. Some studies have indicated that both sexual performance and satisfaction decline with aging. This study shows that sexual activity and satisfaction are more strongly correlated with one's degree of fitness than one's age. Physical fitness and sexuality activity should be mutually-supportive elements of successful aging.
