Abstract:
Michigan-type computerized biomechanical models have the potential to predict hazard levels of exertion in many activities besides lifting. With suitable refinement, they could provide guidelines for non-lifting activities in a shorter term than can be expected from epidemiological and psychophysical studies. This paper examines some of the assumptions in the models, particularly as regards muscle action at joints. Observed features of whole symmetrical exertions are described which could be used for comparison with and validation of the simpler models before extending their use to production in the real-life conditions of asymmetrical exertions.

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...

What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system as it...
