|
Why use Karnoven's formula?
|
Directly correlates to VO2 max
%(HRmax - HRrest) + HRrest |
|
|
Where should RPE be for endurance ex
|
13-16
Somewhat hard to hard "Talk test" |
|
|
How is endurance training diff for obese ppl?
|
Should ex at longer durations and lower intensities b/c obesity increases the mechanical work of the heart
|
|
|
exercise induced asthma: how should pt breathe
|
Thru nose, which warms and humidifies air
|
|
|
How long for warm up and cool down period. why use this?
|
5 to 15 minutes each
Cool down to prevent venous pooling Longer periods may be needed for deconditioned or older ppl |
|
|
Why is there a drop in aerobic performance at altitudes > 6000 feet?
What does this reult in? |
pp of oxygen is reduced
Results in hyperventilation and increased heart rate Hyperventilation causes a drop in CO2 and resp alkalosis |
|
|
Adjustsments or acclimization protocol for higher altitude training?
|
Take 2 weeks at 2300 feet and an additional week for every 600 meters
Will get a dec in plasma and inc in RBCs with training This type of training has not shown to be beneficial |
|
|
What happens with oxygen delivery when exercising in hot weather?
|
Blood is shunted to periphery and muscles are deprived of oxygen
Core temp and sweating increases Need lots of fluid (use room temp) |
|
|
How long does it take to acclimitize to heat stress?
|
10 days
Ex capacity is inc'd CO is better regulated Sweating is more efficient This DOES NOT seriously deteriorate with age |
|
|
What does the GTO do during stretching?
|
Inhibits contraction of the mm
When excessive tension develops, GTO fires and ihibits alpha motor neuron firing Autogenic inhibition |
|
|
Why should stretching of non contractile tissue be done cautiously in the elderly?
|
Collagen loses its elasticity and tissue blood supply is dec'd, reducing healing capacity
|
|
|
Dynamic stabilization, conrolled mobility
|
Proximal segmens provide a stable base for fxt movts
Weight shifting |
|
|
Dynamic stabilization, static-dynamic control
|
Maintain postural stability during dynamic extremity movements
ie. kicking a ball, reaching |
|
|
Feedback given to pt during intial balance training? Later in training?
|
Knowledge of results early
Knowledge of performance later |
|
|
2 PNF techniques to improve coordination
|
Stabilizing reversals
Rhythmic stabilization |
|
|
Consequences of hydrostatic pressure with aquatic therapy
|
Shunt blood from periphery to core
Inc SV by 30 Dec in VC by 8-10% Harder to breathe |
|
|
Contraindications to aquatic therapy
|
B/B incontinence
Severe kidney dx Severe cadiac or resp dysfxt Severe PVD |
