Ch 4 Lesson 5 Physical Activity Injuries

By the end of this lesson you will be able to:
Identify weather-related risks associated with
various physical activities
Analyze strategies for preventing & responding to
accidental injuries related to physical activity
Identify physical activity injuries requiring
professional health services for people of all ages
Temperatures can be
extremely high or
extremely low.
Factors like wind,
humidity, and air
pollution can increase
your risk of injury.
Also pay attention for
weather warning for
thunderstorms, or
Heat Cramps – muscle spasms
that result from a loss of large
amounts of salt and water
through perspiration.
Heatstroke – a condition in
which the body loses the
ability to rid itself of excess
heat through perspiration.
This causes Hyperthermia – a
sudden increase in body
Overexertion – over working
the body. This is related to hot
weather problems.
Example is heat exhaustion,
cold clammy skin, dizziness,
headache, shortness of
Frostbite - a condition that
results when body tissue
becomes frozen.
Early signs called frost nip,
this is when skin becomes
Hypothermia – a condition
in which the body
temperature becomes
dangerously low.
The brain can not function
and the body systems begin
to shut down.
Dress in 3 layers
Pull moisture away from
Provide insulation.
To keep wind out.
70% of the body’s heat is lost
through the head.
During cold weather
activities start slow and be
sure to warm up your
It is just as important to stay
hydrated in cold weather as
warm weather.
Sunburn – is the
burning of the outer
layers of the skin.
Prolonged exposure to
the sun can speed up
the skins aging process
and increase the risk of
developing skin cancer.
The most dangerous
hours for UV exposure
are from 10:00 am to
4:00 pm.
Cover as must as your
body as possible when
outside and wear
broad-brimmed hats.
Use sunscreen and lip
balm of at least 15 SPF.
Apply sunscreen 30

outside and every 2
hours that you are in
the sun.
Also put sunscreen on
again after swimming.
Muscle Cramp – is a
spasm or sudden
tightening of a muscle.
Strain – a condition
resulting from
damaging a muscle or
Sprain – is a injury to
the ligament
surrounding a joint.
Rest - avoid using the
affected joint.
Ice – this helps to reduce
swelling. Ice for 20 minutes
then remove for 20 minutes.
Compression – light
pressure through the use of
an elastic bandage can help
to reduce swelling.
Elevation – Raise the affect
limb above the level of the
heart to reduce pain and
Fracture and Dislocations –
 fractures are any break in a
bone. Fractures require
immobilization to heal.
 Dislocations are when a bone
is forced from it normal
position in a joint.
Tendonitis – condition in which
the tendons are stretched and
torn from overuse.
Concussion – is a result from a
blow to the head and can cause
swelling of the brain, resulting in
unconsciousness or even death.
What is hypothermia? With which types of
weather is this condition often associated?
Analyze & describe strategies for preventing
muscle soreness after a workout.
Identify which injuries described in this lesson
require the attention of professional health
Explain why muscle cramps might be more
dangerous for a swimmer than for a jogger.
