Q

What was the background on the study “superior cardiovascular effect of aerobic interval training versus moderate continuous training in heart failure patients”

A

Exercise training reduces symptoms of chronic heart failure. Which exercise intensity yields maximal beneficial adaptations is controversial. It has been reported that 88% and 49% of patients with a first diagnosis of chronic heart failure are older than 65 and older than 80. Despite this, most previous studies have excluded patients with an age above 70
Their objective was to compare training programs with moderate versus high exercise intensity with regard to variables associated with CV function and prognosis with post infarction heart failure

23
Q

What are the 3 different types of interval conditioning

  1. Spontaneous conditioning: getting skilled up; feeling fitter

2 fitness conditioning: getting trained up

  1. Performance conditioning: getting even fitter
24
Q

They utilize both aerobic (#___) and anaerobic (#__)

A

They form a logical progression continuous for training

They utilize both aerobic (#1,2,3) and anaerobic (#2,3)

25
Q

Spontaneous training: (getting skilled up)

What are the impacts on ADL and what is the RPE

A

“i want to reduce breathlessness enough to get to the store and back without stopping and without feeling so exhausted that i need to rest for the whole day”

RPE = 9-11

26
Q

Fitness conditioning: getting trained up

What are the impacts on ADL and what is the RPE

RPE= 11-13

27
Q

Performance conditioning: getting fitter

What are the impacts on ADL and what is the RPE

All!

-HR most common

yes
