Homeostasis is when the body is made to be kept at a constant internal environment
despite the changes going on from the external, outside environment, for example exercise.
During exercise different changes happen in the body to attempt to deal with the changes in
the environment. The nervous system passes on and receives signals about the
temperature, hydration, blood pressure, blood pressure etc. which are all necessities in the
human body in order to survive. A human body automatically uses a feedback system during
exercise to maintain normal temperature levels and water levels. During exercise the
internal environment is changed and causes the body to go through stress. It is through the
homeostasis feedback mechanisms that the body is able to be changed to a constant and
healthy internal environment and go back to the normal rates after the exercise has
finished. There are two types of feedback mechanisms that are involved in homeostasis.
Negative feedback mechanism changes the variable back to its original state, so in the case
of exercise, it is used during the exercise to adjust the output change and make it back to its
normal state. Positive feedback mechanism is not a part of the process of keeping the
internal environment changes back to its normal state during exercise.
Whilst exercising, your body needs to maintain a constant amount of oxygen supply in your
body and blood in order to keep your muscles working, which would naturally be a lot more
than the usual amount of oxygen than when they are resting. The harder you exercise the
quicker your breathing rate becomes, which helps to release carbon dioxide from your
body. Another probable homeostatic response in relation to the change of breathing rate
would be allowing all that excess carbon dioxide to be released in order to prevent the
build-up of lactic acid, which would then cause for the individuals exercise to stop as they
are unable to continue with all the excess carbon dioxide. The probable response in
summary would be sending more oxygen around the individual’s blood in order for the
individual to take extra breaths and exhaling the carbon dioxide out of their system.
Through the exercise the body of the individual converts the food that had been taken into
the body into energy to allow the person to continue exercising healthily, but a factor of
that change is the production of heat as a waste product. During exercise it is normal for an
individual to become hot and sweaty, this is a homeostatic response to the change in
temperature. When a person becomes too hot, their hair muscles relax, and they lie flat on
their skin to allow their body to let out more heat. As well as this you start to sweat which
gets secreted from their sweat glands from inside their body, which then evaporates over
time to cool the skin and gradually cool down the body. As well as this the capillaries in the
person’s blood dilate and the blood flow increases which causes heat to be lost via the
radiation being let out.
Your body naturally breaks down carbohydrates into glucose to allow energy to be
transferred and used in the body. All the extra glucose that is broken down is transferred
into glycogen and becomes stored in the liver and muscle cells. During exercise the internal
environment changes, for example the blood glucose levels, which causes for the body to
become dizzy and weak, leading to the homeostatic response being the glycogen storage to
be released in order to increase the blood glucose levels in order to bring it back to the
constant state. An individual who exercises a lot is expected to eat a high carbohydrate diet
such as fruits, vegetables and grains, meaning less of the other nutrients in order for the
body to have more glucose to store for it to be released as energy when needed.
