The only treatment that can break the cycle is exercise.Įxercise provides powerful health benefits for quality of life, physical function, and independent living throughout the life cycle. The vicious cycle contributes to further inactivity and deterioration of physical function. This loss causes the perception of effort associated with even sub-maximal work to worsen, as the anaerobic threshold decreases. With avoidance of activity requiring effort, there is increased loss of exercise capacity. A vicious cycle of decline occurs between inactivity and loss of skeletal muscle mass which accelerates with age. Surveys of PA across the lifecycle show that physical exercise peaks in the middle high-school age range and begins declining through high school and into adult life. Low recreational physical activities have been associated with a threefold increase for major weight gain in men and a fourfold increase in women. The decline in physical activity (PA) occurs both at work and in leisure time, and may have at least partially contributed to the increase in obesity over the past 30 years. For most states in this country, less than half of the population meets CDC exercise recommendations. Physical exercise reduces the risk of premature death and prolongs longevity, and is an important treatment modality in the primary and secondary prevention of the above disorders. Physical inactivity is a modifiable risk factor for cardiovascular disease, obesity, depression, cancer, diabetes mellitus, hypertension, and osteoporosis. Patients should understand that for optimal health, exercise is no longer optional. Physicians should recommend near daily exercise which includes at various times strength training, stretching, and aerobic activity in addition to emphasizing adjustments that allow for reduced sitting and increased activity during daily routines. The health benefits of exercise appear to be dose-dependent. Almost any form of physical activity (PA) is beneficial, whether part of a regular exercise program or as a series of intermittent, incidental, non-purposeful, lifestyle-embedded activity (causing non-exercise activity thermogenesis or NEAT). Prolonged periods of occupational or leisure-time sitting have adverse health effects independent of exercise performed before or after. The physiologic mechanisms for such a benefit occur at both a cellular and multisystem level. Exercise provides a clear health benefit, which serves in the primary and secondary prevention of these disease processes (the most important being a reduction in cardiovascular disease and premature death). Physical inactivity is a modifiable risk factor (similar to dyslipidemia and hypertension) for a variety of chronic diseases, including cancer and cardiovascular disease.
