Table 1. Homeostasis.

Homeostatic

mechanism

disrupted

by running

a marathon

and how is

it altered i.e.

increased or

decreased

How is the

change detected

What

effector is

involved

What hormonal response

is provided

What would happen if

the response did not

occur within the

marathon runner.

Weight

Taking energy

drinks and

sweating.

Drinking energy

drinks shows that

fat is being

broken down in

the body and

needs

replacement

while sweating

indicates the loss

of excess water to

cool down the

body.

Sweat glands,

liver

Release of glucagon to

metabolize energy.

Break down of fat to

energy.

Release of thyroid

hormones which controls

the rate at which calories

are burnt, which also has an

effect on weight loss and

gain.

The runner would lack

enough energy to

continue the marathon

and this would’ve

resulted in failure to

complete the race.

Also, obesity and

obesity-related

disorders including

metabolic syndrome,

hypertension,

hyperglycemia, and

dyslipidemia can all be

caused by thyroid

dysfunction.

Heart Rate

Heart beats more

rapidly.

Heart

Release of adrenaline

hormone. These hormones

aids in the increase of heart

muscle contraction power,

the increase in blood flow to

working muscle (to a point),

the reduction of blood flow

to non-working muscle, and

the mobilization of substrate

molecules for use of certain

tissues. In general, the heart

rate and the force of

contraction of the heart are

both increased by

adrenaline. As a result, the

runner gets more blood

supply if you have more and

more contractions.

The runner would lack

enough oxygen because

the rate of contractions

would be low in the

heart their heart and

thus would not be able

to supply more blood

with oxygen which is

needed to produce

enough energy required

to replace energy lost

through heat and in the

muscles.
