what are the 2 types of fatigue?

(a)  

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

(a)  

It persists, and recovery is not quickly
anticipated.

(a)  

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

(a)  

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

(a)  

if possible, rotate the work so
the heavy work is performed in
the morning and the lighter
tasks are performed in the later
part of the day

(a)  

Provide information on proper body positioning (neutral posture), or proper lifting techniques to the workers. Educate them on how to identify WMSD risk factors, signs, and symptoms before an injury occurs

(a)  

Encouraging stretching increases blood flow and whisks away waste products. It increases flexibility, and they are less likely to injure a warm muscle

(a)  

We all take brief pauses in work and these
pauses can be energy pauses, as in doing
something such as stretching, which aids
in recovery by re-oxygenating the
muscles
