P. E EXAM Flashcards
Individuals who engage in various
types of physicalactivities such as
sports and exercise have ahigher
risk of getting injured as compared
to thosewho practice a sedentary
lifestyle. However, thepotential ben-
efits of an active lifestyle outweigh
therisks of suffering an injury.
Most of the injuries are preventable
andawareness of the risk factorswill
help in reducingthe risk.
Furthermore, vigilance and safety
measurescan dramatically reduce
the occurrenceof injuries
SPORTS INJURIES
Damaged tissues or organs which
occur when itencounters trauma or
physical force that is greaterthan
what it can resist or absorb
INJURIES
Able to withstand varying degrees
of stress andstrain but itwill brea-
kdown if it experiences animpact
that is stronger than what it can tole-
rate.
TISSUES
What are the factors influencing
The ability oragan/tissues to effectively resist /absorbed forces
inherent abnormality• age
• technique
• fitness level
• equipment
• environmental aspect
impact the center causing it to
bend or fold
COMPRESSIVE FORCES
actawayfromthecen-
terofthestructure, causinga pull or
stretch
TENSILE FORCES
opposing forces toward thedif-
ferent ends ofthe structure cau-
sing it to twist
SHEAR FORCES
have signs and symptoms that
manifestimmediately after force
application
ACUTE INJURIES
an overstretched ligaments;
can be mild,moderate, or severe
– lower
limbs(ankleand knee)
commonly sprained ligament –
anteriorcruciate ligament
SPRAIN
aconnective tissuethat helps
stabilize the knee every time the
muscles contract
ACL/ anterior cruciate ligaments
caused by excessive stretching
that causestears in the muscle-
tendonunit
- lower
limbs(hamstring and calf muscle)
A person who suffers a strain will
feel a
sudden sharp pain at the muscle
belly
STRAIN
breaks in the continuity of the
bone
upper
limbs (handand forearm)
Healing period is between 3 weeks
to severalmonths depending on
theseverity of theinjury
normally treated with immobil-
ization byattaching a fixator or a
cast
FRACTURES
bones that are pushed out from
their jointcapsule
commonly occur in joints that
allow greaterrange of motion
upper
limbs(shoulders and elbows)
The pain will be relieved once
the bone is
repositioned
DISLOCATION
Life-threatening injuries because
theydisrupt the normal func-
tion of the brain
If not resolved immediately, the
starts to die
CONCUSSION
the signs and symptoms occur after a long
period of exposure to the force.
CHRONIC/OVERUSE INJURIES
