The effect of high dose oxprenolol on stress-induced physical and psychophysiological variables
Abstract:
The effects of oral oxprenolol (480 mg) and lorazepam (2 mg) on skin conductance, reaction time, critical flicker frequency and self-rating visual analogue scales for anxiety, sedation and concentration were investigated in 6 healthy male volunteers. Oxprenolol exerted a central action similar to lorazepam as shown by a significant lowering of skin conductance and decrease in the number of spontaneous fluctuations during stress, impaired critical flicker frequency and decrease in alertness with reduced concentration.

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...
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.
