Transcript Unit 2a Physical Activity and Injury

Physical Activity and Injury
OBJECTIVES:
List and describe some activity related
physical injuries.
 List some guidelines for preventing injuries
during physical activity.
 Explain how to apply the RICE formula to the
treatment of physical injuries.


Identify different types of risky exercises.
VOCABULARY YOU SHOULD KNOW:

Biomechanical principles

Ligament

Micro Trauma

Overuse injury

Side Stitch

Tendon
COMMON INJURIES


?? What are they in your sport??
blisters


cuts

dislocations
strains


sprains
bruises

fractures
COMMON INJURIES

skin


feet
Leg muscles


ankles
knees
OVERUSE INJURY

Caused by repetitive movement.

Blister most common

Shinsplints

Runners Heel
COMMON INJURIES

“Side Stitch”
Pain in lower abdomen due
to vigorous activity.
Press heel of hand while bending forward or
backward.
 Micro= small
 Microtrauma:
trauma = injury:

Often won’t show up on x-ray. “overuse”
PREVENTING INJURIES

How many bones?

Held together how???

Muscle contraction = body movement.

Biomechanical principles=
1) Don’t force in direction not designed to go!

Muscle contraction =
TENDONS VS LIGAMENTS
Preventing Injuries

Biomechanical principles=
1) Don’t force in direction not designed to go!
2) Movement shouldn’t over stress bones,
tendons, ligaments or muscles.
3) Balance muscle development. (“antagonistic”)
PREVENTION GUIDELINES:

1) Start Slowly

2) Listen to body

3) Warm-up/Cool downs

4) Be Fit

5) Moderation

6) Dress Appropriately
R.I.C.E
 R= REST
 I= ICE
 C= COMPRESSION
 E= ELEVATION
RISKY EXERCISES/MOVEMENTS

Goes against biomechanical principles

Hyperflexion vs hyperextension

Hyper = “too much”

Hyperflexion is using joints in a way not
intended.

Flexion = “to bend”
RISKY EXERCISES TO
AVOID
AVOID:
HyperEXTENSION

Opposite of “flexion”
EXERCISES TO AVOID:

Twisting motion: Friction = wear n tear on
joints/tissue.
?? REVIEW QUESTIONS ??

1) What are some exercise related physical
injuries?

2) How can you prevent injuries during
physical activity?

3) How can the RICE formula be used to
treat physical injuries?
4) What are some different types of risky
exercises?
