-pediatrics: birth to puberty=open growth plates, learning curve is significant (learning gross motor skills)
-adolescent (adulthood)=bid chemical changes
-puberty: increase growth, 2nd sex characteristics
-adulthood to geriatric: decreased metabolism, decreased cell repair, decreased muscular capabilities

-growth is complete between the ages of 19-24

common congenital and aquired risk factors
-strength and flexibility imbalances
-improper technique: bad habits
-congenital and acquired heart disease
-previous injuries and surgeries not healed

effects of common illnesses and diseases in physical activity
-increase in heart rate
-labored ventilation rate
-increase in core temperature
-lose of fluids
-metabolic processes have to work extra hard to maintain homeostasis from normal ADL’s as well as fight illness, recover from injury, etc.
-NECK DOWN: DISCONTINUE (internal illness); NECK UP (play ball)
