ReviewExercise and diet, independent of weight loss, improve cardiometabolic risk profile in overweight and obese individuals.
Diet and/or exercise are routinely advised as methods for weight loss in overweight/obese individuals, particularly those who are at high risk for cardiovascular disease and type 2 diabetes mellitus. However, physical activity and structured exercise programs rarely result in significant loss of body weight or body fat, and weight-loss diets have extraordinarily high recidivism rates. ⋯ These lifestyle-induced adaptations occur independently of changes in body weight or body fat. Thus, overweight/obese men and women who are at increased risk for cardiovascular disease and type 2 diabetes as a result of sedentary lifestyle, poor diet, and excess body weight should be encouraged to engage in regular physical activity and improve their diet, regardless of whether the healthier lifestyle leads to weight loss.

Comparative StudyAutomated external defibrillators in health and fitness facilities.
Exercise is encouraged to promote health, but it can be a trigger for sudden cardiac arrest (SCA) in individuals with underlying cardiovascular disease. In 2002, the American Heart Association and the American College of Sports Medicine issued recommendations for the presence of automated external defibrillators (AEDs) in health and fitness facilities. ⋯ There is a substantial gap in guideline implementation between national recommendations and current emergency response planning for SCA in health and fitness facilities. Health and fitness facilities are strategic locations to place AEDs in an effort to improve outcomes from exercise-related SCA. Facilities with general memberships of > 1500 are encouraged to have on-site AEDs, given the high incidence of SCA.
