Exercise Dose-Response Effects in Prediabetes
The purpose of the study is to evaluate the effects of different amounts and intensities of aerobic exercise training programs, with and without weight loss, in people who are at risk for diabetes. An additional purpose of the study is to evaluate the factors in the blood and in exercising muscles that contribute to the improvement in those risk factors. This information will be used to improve exercise training guidelines for improving cardiovascular and metabolic health in people with abnormal fasting glucose, also known as prediabetes.

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.
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.
Transient reduction in blood pressure levels immediately after exercises that lasts 2-12 hours. The reduction varies but is typically 5-20 mm Hg when compared to pre-exercise levels. It exists both in normotensive and hypertensive individuals and may play a role in excercise related PHYSIOLOGIC ADAPTATION.
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...
Aerobic exercise has the potential to become an effective and easily accessible treatment for Parkinson's disease (PD) that can improve both cognitive and motor dysfunction. This project w...
This study aims to investigate the effect of aerobic exercise on the aerobic capacity, the daily functioning, post-stroke fatigue , depression and cardiovascular risk factors in stroke pa...
This is a randomized, 26-week study of supervised exercise assessing three doses of exercise in sedentary individuals 65 years of age and over with age-related cognitive changes. A total...
Aging is associated with declines in aerobic capacity, exercise tolerance, and functional endurance that lead to physical disability and loss of independence. Furthermore, the existing hi...
Abnormally elevated exercise blood pressure is associated with an increased risk of cardiovascular disease. Aerobic exercise training has been shown to reduce exercise blood pressure. However, it is u...
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...
The purpose of this study was to evaluate the profile of serum iron in spontaneously hypertensive rats after an aerobic physical exercise. To accomplish this, 12 normotensive Wistar rats and 12 sponta...
The purpose of this study was to investigate the effect of 6 months aerobic exercise and diet alone or in combination on markers of inflammation (MOI) in circulation and in adipose abdominal tissue (...
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...
