CV Exercise Flashcards
Prescription using HR Max
55%-90% of HR Max
Prescription using HR Reserve/Karvonen
(HR max - HR rest) * (40-85%) + HR Rest
General CV Exercise Prescription
20-60 min/day, 3-5 days per week
Duration for lower level CV exercise
> = 30 min
Duration for higher level CV exercise
> = 20 min
Cardiac Rehab Phase I Exercise Parameters
RPE
Cardiac Rehab Phase II Exercise Parameters
RPE 11-13, 14-16 if no symptoms Standard HR criteria 15 min building up to 40 min 3-5 days per week Post-hospitalization up to 12 weeks
Cardiac Rehab Phase III Exercise Parameters
Same as phase II, pt more independent
Cardiac Rehab Phase IV Exercise Parameters
Same as phase II, pt totally independent
Prescription using METs
(Max METs - Resting METs) * (40-85%) + Resting METS
METs for slow walking
2.0 METs
METs walking 3 mph
3-4
METs walking 4 mph
4.5-7
METs jogging 5 mph
8
METs running 7 mph
11.5
METs making bed, washing dishes
2
METs light gardening
3-4
METs shoveling
7
Typical BP response to exercise
SBP: Increase 10 mm Hg per MET level
DBP: Stay the same or drop slightly
Drop in SBP a concern
Normal max aerobic capacity for adults (in METs)?
8-12 METs
MET to VO2 conversion
1 MET = 3.5 mL O2/kg/min
Role of various nutrients in supplying energy for activity
Activity > 1 hour, fats play greater role
Intensity > 70% VO2 max, carbs play greater role
Walking prognosis - myelomeningocele
Walking in the home and community using only AFOs would be possible for a child at L4–L5
A child with a L3–L4 myelomeningocele would be expected to achieve community ambulation using KAFOs
A child with L1–L2 myelomeningocele would be expected to walk short distances in the home with KAFOs
Standing in parapodium would be an appropriate prognosis for a child who has a thoracic–level myelomeningocele
