Effects of Exercise Modality on Abdominal Obesity and Health Risk Factors in Older Men and Women
The prevalence of abdominal obesity in the elderly is increasing at alarming rates and thus, requires immediate attention. By comparison to younger adults, obesity reduction in the elderly presents a unique challenge and requires an innovative approach. We propose a novel approach to investigate the effects of different exercise types as independent treatment strategies for the reduction of obesity and related health risk factors in older men and women. We propose that exercise without caloric restriction will be associated with modest weight loss (3-5%), that in turn will be associated with significant reduction in abdominal obesity, insulin resistance, and a corresponding increase in skeletal muscle mass and function. We will determine the separate effects of resistance and aerobic exercise on these primary outcome variables, and, whether a treatment strategy that combines the two is optimal.

Medical and Biotech [MESH] Definitions
Controlled physical activity, more strenuous than at rest, which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used. The intensity of exercise is often graded, using criteria such as rate of work done, oxygen consumption, and heart rate.
A type of strength-building exercise program that requires the body muscle to exert a force against some form of resistance, such as weight, stretch bands, water, or immovable objects. Resistance exercise is a combination of static and dynamic contractions involving shortening and lengthening of skeletal muscles.
The exercise capacity of an individual as measured by endurance (maximal exercise duration and/or maximal attained work load) during an EXERCISE TEST.
Asthma attacks following a period of exercise. Usually the induced attack is short-lived and regresses spontaneously. The magnitude of postexertional airway obstruction is strongly influenced by the environment in which exercise is performed (i.e. inhalation of cold air during physical exertion markedly augments the severity of the airway obstruction; conversely, warm humid air blunts or abolishes it).
A method of recording heart motion and internal structures by combining ultrasonic imaging with exercise testing (EXERCISE TEST) or pharmacologic stress.
The purpose of this study is to identify the body's response to aerobic vs. resistance exercise. Throughout this study, we will examine food intake, appetite, and physical and mental well...

BACKGROUND: Aerobic exercise training is known to increase red blood cell production; however, this has not been evaluated in breast cancer patients undergoing adjuvant chemotherapy (CT). The purpose...
Post-exercise hypotension (PEH) may follow a session of physical exercises. This effect has high clinical relevance for hypertensive individuals. Although there are several studies on the subject, an...
