by the body: often used as a supplement
to maintain cartilage in the joints.
Chondroitin-naturally occurring substance
in humans and animals: often used as a
supplement to treat osteoarthritis.
Performance Enhancers


Ergogenic aid- any agent that enhances
energy utilization, including energy
production and efficiency. (book)
Ergogenic Aid- any agent that enhances
performance. (Jen Croll)
Performance Enhancers

It is estimated that between 1 and 3
million athletes in the USA have used
anabolic steroids.
Performance Enhancers

Anabolic Steroids-substances that are
used to enhance metabolism and thus act
to build up the body tissues



Anabolic-muscle building
Androgenic-masculine characteristics
Steroids-specific class of drugs
Performance Enhancers

Anabolic Steroids

Used to enhance appearance and
performance
Stacking/cycling-cycling on and off
weeks/months with different drugs to get max
effect and min side effects.
Performance Enhancers

Anabolic steroids

Numerous side effects (pg 156)
Approximately 10% of men in one clinic say
steroids was their gateway drug to others.
They did this to counteract side effects from
the steroids.
Performance Enhancers


Growth hormones- a substance naturally
produced in the body by the pituitary
gland, it work to increase conversion of
amino acids into protein. It allows fat to
be used as an energy source instead of
muscle glycogen.
Side Effects-heart disease, impotence,
osteoporosis and death.

supplement to increase skeletal muscle.
Performance Enhancers

Creatine Monohydrate





Found in the liver and kidneys
1992 study found it increase muscle by 20%
It increases energy produced during exercise,

body
