The Body's Response To Acute Exercise

This presentation explores the body's response to acute exercise, focusing on the musculoskeletal, energy, cardiovascular, and respiratory systems. It discusses the physiological changes that occur during exercise and the benefits of regular physical activity. The presentation also includes references for further reading.

Introduction
The body has various manner to respond exercise such as it increase the flow of blood and
oxygen in a maximize volume. The exercise can effect body and helps in measuring aerobic
fitness of the body. It also describe the measurement of oxygen that muscles required in
order to perform an activity.

The musculoskeletal and energy system
response to acute exercise.
The acute exercise refers to a
particular period of intense activity or
exercise. It makes the breath harder
and help in building muscle and
strength of body. This type of exercise
can lower negative effect and raise in
positive effect in body.

Cont.
The musculoskeletal system provide movement of body by use of various ligaments and
muscles. It perform various functions such as support, stability to body. This system is
made up of muscles, cartilage, joints and tissue that connect different organs together.
These responses are described below.

Cont.
Blood supply:- While doing exercising the blood pressure needs to be raise in order to
perform good function of body so it is required to increase level of oxygen in body.
Muscle pliability:- After exercise, muscles become more flexible which is a good sign
of reducing the risk of various injury.

Cont.
Range of movement:- The exercise influences the range of movement of body by making fluid
between joints vicious. At the time of exercise, joints become warmer which leads to raise
temperature of body.
Muscle fiber micro tears:- the exercise an effect muscle fiber micro tears as muscles consist of
various fibers.

The energy system response
The energy is required to perform activities and movements that are signalling from
brain. It is necessary to develop contraction of muscle fibres. The energy can be obtained
through carbohydrates and fat through foods.

Cont.
Phosphocreatine energy systems:- the phosphocreatine is stores in ATP-PC system
which is required for an high activity.
Lactic acid system:- this system provides energy to body when activity is performing
for long duration for a shorter period of time.

Cont.
Aerobic energy system:- during exercise, oxygen and glucose are breakdown so the
oxygen are needed as a source of energy.
Energy continuum:- in this, energy are taken from food and resources which are
transferred into muscles to increase the ability to exercise with intensity.

The cardiovascular and respiratory
responses to acute exercise
It is a system which controls the flow of blood to
all organs of body. It regulates oxygen, waste
products and nutrients of body. In this response
occur when the heart beats faster while doing
exercise.

Cont.
Anticipatory rise:- the normal heart rate of a healthy person is 60- 80 beats per minute
but in aged people it has raise to 100 beats per minute. This is differently occur in
sports person as they have 28-40 beats a minute.
Blood pressure:- this is the most important sign that occur in the body. There are two
types of blood pressure at the time of exercise such as high blood pressure and low
blood pressure.

Vasodilation:- The cardiovascular system helps in regulating internal temperature of body. This
response occur when temperature increase of body which result in increase in the size of blood
vessels.
Cont.

The respiratory response to acute exercise
The main function of this system is to deliver oxygen through out the body. The person can
supply oxygen though breathing. In this, lungs and tubes provide oxygen to muscle and
tissues. This also helps in eliminating carbon di oxide from body.

Cont.
Breathing rate:- the increase in CO2 and decrease in oxygen, it makes faster breath.
While doing exercise, the muscles require more oxygen to function properly so it
develop more breathing rate from which it allow to oxygen to enter in the body.
Tidal volume:- it refers to volume of air that are breath in and out in 1 breath. The tidal
volume increases at the time of exercise when the requirement of oxygen increases.

The response of cardiovascular, respiratory,
muscular and energy systems to acute
exercise.
The responses occur in muscular system occur as exercise demands lots of
muscles contraction to perform exercise. This responses occur as different parts
of system work upon functioning of nervous system. The muscle are fleshy
which is [reset around the bones.

Cont.
This response occurs as the time of exercise, muscles need more blood to perform metabolic
activity. By increasing temperature, the muscles start reacting and responding which leads to
various changes in body.
The response in energy system is occur as energy required to perform a exercise properly. As
each individual has different energy while sprinting as they need higher energy more than
who run for a long period of time.

Cont.
While doing exercise, the muscles start contracting which leads to supply of more oxygen
in body. The heart rate increases at time of exercise. So the oxygen and nutrients are
required while doing exercise.
The response from respiratory system is occur by replacing the amount of CO2 by
oxygen. The tidal volume increases according to demand of exercise that are performed
by person.

Continue…
The initial response benefits the sport person as these responses can help them in
repairing their injuries with effectively. The aerobic example of this can be jogging that
are occur for a short period of time.

Conclusion
From the above ppt, it has been concluded that various responses are occur from
exercise different systems. These systems are such as musculoskeletal, cardiovascular,
energy and respiratory systems.
