Aerobic Requirements of Arm Ergometry: Implications for Exercise Testing and Training
Abstract:
In brief: To compare the oxygen cost of submaximal and maximal arm and leg exercise, ten healthy men (mean age 28 years) underwent multistage arm and leg ergometer tests using standard open circuit calorimetry. VO2 during arm exercise was greater than leg exercise at any given work load. Peak work load during arm work (675 kpm-min(-1)) was only 55% of the peak work load during leg work (1,230 kpm-min(-1)). VO2 max during arm work (10.5 mets) was 80% of the VO2 max during leg work (13.2 mets). Since arm performance tends to be a poor predictor of leg performance and vice versa, arm ergometry appears to be the preferred exercise mode for the functional evaluation of select patients.

Exercise 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...
Exercise 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
Exercise 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...
