The benefits and risks of exercise training: the exercise prescription
1Boston University School of Medicine, University Hospital, Boston University Medical Center, Massachusetts.
Abstract:
The physiologic responses to exercise are mediated by a complex interaction of central, peripheral, and neurohumoral stimuli designed to increase cardiopulmonary function. With repetitive exercise, significant cardiovascular and muscular adaptations occur that facilitate and enhance the response to exercise. Exercise is beneficial not only to younger healthy individuals, but to patients with many chronic medical conditions and to elderly individuals as well. Physical activity has a role in the reduction of major cardiac risk factors and in both the primary and secondary prevention of cardiac events. With proper evaluation and counseling, exercise can be performed safely, even among patients with cardiovascular and other chronic diseases. Given the high percentage of the U.S. population whose sedentary lifestyle predisposes them to the development of cardiovascular disease and the numerous beneficial effects of exercise, it is prudent to prescribe exercise as a means of improving individual and general public health.

01:27Exercise and Muscle Performance
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Sustained exercise increases the muscles' oxygen demand, which can be met...
01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

01:26Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes

The Role of Exercise in Stress Management
Regular physical activity is essential for reducing stress and promoting cardiovascular health. Exercise strengthens the heart, enhances blood flow, keeps blood vessels flexible, and helps lower blood pressure, all of which reduce the body's stress response. Research shows that adults who exercise regularly have nearly half the risk...
