Basic Components of Physical Fitness of Human Beings
To
take better efficiency we know machine environment as well as human configuring
to work is essential. It means worker should enthusiastic as well as energize. In
depth distribution we know human body is biological thing. Therefore its energy
and capability is very important. Under the physical fitness such details are
discussed. In depth learning about physical fitness following points can be
explained.
Cardiorespiratory (CR)
endurance
Under
this point is discussed how human body cells take oxygen and how its
consumption and consumption speed and especially this is very important for proper
muscular activities. This topic related to metabolism. In metabolism, body
taken foods are absorb into body and produces energy. For this operation need
to take atmospheric oxygen. Oxygen is taken from nose and it is absorbed and
filtered by lung and oxygen are combined by bloods hemoglobin and transported
to each cells and here in each cells intake foods are consume aiding oxygen and
convert adenosine di-phosphate (ADP) to adenosine tri-phosphate (ATP) and collect
energy for future energy requirement of body and release carbon dioxide. This
process can be explained using Krebs cycle concept.
In
ergonomics to increase productivity, oxygen intake to the factory flow develops
using plant utilities techniques. And each workplace has developed to take
fresh oxygen and also techniques are developed to emit out carbon dioxide gas. As
well as proper canteen and nutrition planning process is another thing to take
proper physical fitness. And also meal time plan also very important for each
shift of organization.
Muscular Strength
In
this topic find how many strength workers muscular system has and it means how
much energy force can be keep on muscles. We all know human muscles especially
on hands and legs have lever type of movement when working and have to keep
energy some objects are carrying out here and there. Therefore muscular
strength depended on inter tissues and bones cohesiveness. However the maximum
strength of human muscle is between 30 and 40Ncm-2 of cross
sectional area. To improve muscular strength of employee some company launch
sport programs, healthcare tests, exercise program, yoga programs, etc.
Muscular
Endurance
In
muscular strength we discussed strength and Newton force of muscles but it is
not enough in ergonomic discussion because employee has to work extended period
of time. It means employee has to do same works in each time of day and it
means repetition. In this repetition of work sometime employee’s efficiency
will reduce due to tiredness of muscle. To avoid this problem some companies
offer small refresh time among works. By aiding this leisure period employ can
reset and it it is increase willingness to work and increased aimed efficiency
of each works. Apart this, some companies continues first aids if some cause
and medical instructions are also provided to be health.
Flexibility
In
the workplace employee has to move here and there during operations. Therefore
he/ she has to move joints and skeletal of body hence, body flexibility is an
essential thing is to do this. Some people are very fat and not flexible
therefore working repetition time will high and this is directly affected for
production drop. Therefore selecting people for the particular works need to be
test weather this person match into this work. If not have to arrange environment
and space to be familiar with particular employee. Because although some
workers are very fat but they can be flexible by arranging suitable space in
their workplace design.
Body
Composition
Another
component of physical fitness is body composition and we all know different
body sizes have different employees and some are thin and some are fat. Some
person cannot work correctly because he/ she has extra body weight. The best
example is heat sealing machine operator have to operate machine by standing.
If very fat person is used for this operation, required efficiency cannot be
taken. But sometime this operator may suitable for some sewing and assembling
operation. Not only body mass each body composition should match to proper deal
with machinery environment to take required efficiency. Because some small
operators difficult to work with warp knitting machines. Therefore to control
warp knitting machine it is essential to use tall employee.
