Introduction
5

The ability to impact the environment depends on our capacity for
physical activity.

Movement represents more than just a convenience; it is
fundamental to human evolutionary development—no less
important than the complexities of intellect and emotion.


The exercise physiology is now a separate academic
field of study within the biological sciences.
Exercise physiology as an academic discipline consists of
three distinct components;
1. Body of knowledge built on facts and theories
derived from research
2. Formal course of study in institutions of higher learning
3. Professional preparation of practitioners and future
investigators and leaders in the field.

Introduction
8

Exercise physiology has developed as a field
separate from physiology because of its unique
focus on the study of the functional dynamics and
adaptations to human movement and associated
physiological responses.

Definition
9

Exercise physiology can be defined as both a
basic and an applied science that describes,
explains, and uses the body’s response to exercise
and adaptation to exercise training to maximize
human physical potential.

Exercise Physiologist
10

Many individuals view exercise physiology as an undergraduate or
graduate academic major (or concentration) completed at an
accredited college or university.

In this regard, only those who complete this academic major have
the “right” to be called an “exercise physiologist.”

WHAT DO EXERCISE PHYSIOLOGISTS DO?
11
Exercise physiologists assume diverse careers;

Colleges

Universities

Private industry settings

Health, fitness, and rehabilitation centers, personal
trainers, managers, and entrepreneurs in the health and
fitness industry.

Sports Medicine and Exercise Physiology
: A Vital Link
13

Sports medicine professionals and exercise physiologists work
hand in hand with similar populations. These include,

at one extreme, sedentary people who need only a modest
amount of regular exercise to reduce risk of degenerative
diseases, and

at the other extreme, able-bodied and disabled athletes who
strive to further enhance their performance.

Sports Medicine and Exercise Physiology
: A Vital Link
14

In their clinical role, exercise physiologists alongside
sports medicine professionals test, treat, and rehabilitate
individuals with diverse diseases and physical disabilities.

Nutrition and Energy
15

Proper nutrition forms the foundation for physical
performance.

The foods we consume provide fuel for biologic work and
chemicals for extracting and using potential energy within
this fuel. Food also provides essential elements to synthesize
new tissue and repair existing cells.

Six broad categories of nutrients:
16
carbohydrates,
 lipids,
 proteins,
 vitamins,
 minerals, and
 water.
Understanding each nutrient’s role in energy metabolism
and tissue synthesis clarifies one’s knowledge of the
interaction between food intake and storage and exercise
performance

Lipid’s Role in the Body
18





Four important functions of lipids in the body
include:
1. Energy reserve
2. Protection of vital organs and thermal insulation
3. Transport medium for fat-soluble vitamins
4. Hunger suppressor

Contribution of Fat in Exercise
20





The contribution of fat to the energy requirements
of exercise depends on two factors:
1. Fatty acid release from triacylglycerols in the fat
storage sites.
2. Delivery in the circulation to muscle tissue as free
fatty acids (FFA) bound to blood albumin.
