17
Q

Maximum heart rate calculations

A

220-age = MMR

208-(0.7xage)=MMR

18
Q

Target heart rate traditional

A

MHR x chosen% = THR

19
Q

Target heart rate- heart rate reserve method (Karvonen)

A

(MHR-RHR) x chosen% + RHR = THR

20
Q

Resting and maximum SV after aerobic training

A

BOTH increase

21
Q

Cardiac output calc

A

SV x HR

22
Q

Ejection fraction calc

A

SV/EDV

23
Q

Opening of a valve is narrowed

A

stenosis

24
Q

valve mechanically incompetent, allows “back flow”

A

regurgitation/insufficency

25
Q

A

approx 70 ml

resting SV may increase up to 100 in elite athletes

26
