what are the 2 types of fatigue?

It has a recent onset and is temporary in duration. It is
usually related to excessive physical activity, lack of exercise, insufficient rest or sleep, poor diet, dehydration, increase in activity, or other environmental factor

It persists, and recovery is not quickly
anticipated.

it is a result of the accumulation of
waste products such as lactate and results in an oxygen debt, which ultimately leads to fatigue

The problem with allowing fatigue
to set in is that it does the
following:
 Degrades physical work
performance
 This causes workers to perform
at a slower rate
 May hinder one's ability to
perform certain exertions
May cause one to suffer from
tremors and other symptoms
that interfere with precision
 Degrades mental capacity
 Increases error rate
