Analyzing the Body's Response to Acute Exercise: Systems and Effects

This report provides a comprehensive overview of the body's response to acute exercise, detailing the effects on various physiological systems. It begins by exploring the musculoskeletal system, highlighting how exercise influences blood supply, muscle pliability, range of movement, and muscle fiber micro-tears. The report then delves into the energy systems, including phosphocreatine, lactic acid, and aerobic systems, and their roles in providing energy during exercise. Furthermore, it examines the cardiovascular and respiratory responses, such as anticipatory rise, blood pressure changes, vasodilation, breathing rate, and tidal volume. The report emphasizes the interconnectedness of these systems, illustrating how they work together to support physical activity. Finally, the report references studies on the effects of exercise on brain-derived neurotrophic factor, providing a well-rounded understanding of the body's reaction to acute exercise.

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.
