Flashcards in Exercise for Diagnosis Deck (14):
1

Bruce Protocol involved what?

successively steeper slopes(too demanding) for walking tests of cardiac patients

2

what is the 'frailty threshold'?

~18ml O2/kg/min

3

What is the double product?

HR and BP

4

If you increase resistance in a test in a step wise fashion, what happens to HR?

on the plateaus, the heart levels out and follows the plateaus

5

VO2 Max take a long time to reach?

Nope, within a minute if going all out

6

lactate production only when anaerobic?

Can happen even with O2 present if needs more energy

7

2 indirect tests:

6min walk test
PWC150/170 (physical working capacity)

8

Does having a high VO2 max all that matters?

It's the ability to use and maintain that high VO2 max during exercise without producing too much lactate

9

more mitochondria mean less?

dependence on carbs

10

VO2 max or muscle oxidative capacity better predictor of endurance?

oxidative capacity (study with iron restoration)

11

lactate threshold?

when you start producing lactate to supplement energy

12

higher lactate threshold means?

more time until fatigue

13

muscle strength vs. mortality

stronger = less mortality

14

muscle strength testing?

1RM
isometric
concentric/eccentric
isokinetic
