9. Is my 13 year old a kid?
Children are not small adults
Anatomy and physiology is
developing and not mature
Despite these concepts which
are intuitively understood in
the broadest sense, in
practice, especially in athletic
pursuits, these distinctions are
forgotten or worse, ignored
10. How come the other kid is faster,
stronger, more coordinated?
11. Should anybody but parents
care?
50% of all children, age 5-18, participate in
organized sport programs
18 million will incur sports related injury this
year.
50% of these are overuse type injuries
Annual cost to treat these preventable
injuries is $1.2 billion

17. Overuse Injury Prevention
Pre-participation
screening
Athlete/parent/patient
education
No pain = no gain??
18. Pain may be the result of a sport injury
Pain is a natural response to something being
wrong
Pain is the barometer for activity continue or stop
Adults have prior experience to qualify pain
Trends can clarify the level of pain and injury
20. Youth specific risks
A child with a shorter stride length subjects themselves to
more repetition of heel strike to cover the same distance as
an adult
Immature cartilage is more susceptible to shear forces than
adult cartilage
Asynchrony of bone growth and muscle tendon elongation.
Bone grows first which is the stimulus for muscle tendon
elongation, the delay may be 3-6 months, during which
time flexibility is significantly decreased
21. Overuse injury progression
Pain only during high levels of activity
Activity stops, then pain stops
Pain will then persist after the activity
stops
Pain worsens with performance altered
Progresses to pain with ADL and with
sleep
22. What are the variables??
Pain present after activity for greater
than 2 hours must significantly
decreases activity
Location
Frequency
Duration
Intensity
Training/competition
Surface, equipment

28. Should your child lift weights??
Stretch and perform light exercise for 10 minutes
6-8 exercises of 10-15 reps, they could do 2-3
more
1-3 sets, minimum of 1-2 minutes between sets
If doing 2 sets, when almost 3, 2x, increase
resistance
Focus on better, smoother, not heavier, faster
They must succeed!!
29. Is the psychological part
overrated ?
Pressed by peers, coaches and
parents they are more likely to
ignore injury when it first begins or
to use it as an escape technique
