421 Final: CRF Testing

Question 0

Field Tests

Answer 0

• Predetermined time/distance

- Fitness predicted through HR response OR distance achieved

Question 1

Assumptions for estimating VO2max from Submax testing (4):

Answer 1

• subjects effort is appropriate
• aerobic fitness is the limiting factor
• test is appropriate for testee
• HR linearly related to VO2

Question 2

What are the 3 Submax Field Tests?

Answer 2

• Rockport 1-mile
• 1.5 mile run
• Cooper 12 minute run/walk

Question 3

Rockport 1-mile

Answer 3

• good for older people/ low fitness level
• walk as fast as possible on measured track
• HR measured at the end

Question 4

1.5 Mile Run

Answer 4

Variable obtained = TIME (min)

• good for young/healthy, should be able to run for 15 minutes continuously
• ensure flat area

Question 5

Cooper 12-minute Run/Walk

Answer 5

Variable obtained = DISTANCE (m)

• good for people in btw Rockport and 1.5-mile
• jog/run or walk as fast as possible for 12 min

Question 6

What are the 4 Submax Lab Tests?

Answer 6

• Astrand bike test
• YMCA Bike Test
• Balke (treadmill- inc. grade)
• Bruce (treadmill- inc. grade and speed)

Question 7

What is the criteria for reaching VO2max (4)?

Answer 7

1. Paella yeah in VO2-
2. RER >/= 1.1- ratio btw CO2 and O2
3. Post-Ex Lactate = 8mmol
4. HRmax within 10bpm of APMHR or 85% of APMHR

Question 8

When is it appropriate to terminate a YMCA bike test (2)?

Answer 8

Complete when:

• 2 consecutive stages with HR btw 110 and 85% APMHR
• 2 consecutive stages with steady state within 5bpm during last 2-min

Question 9

When should an Exercise Test be stopped?

A D E S

Answer 9

A- onset of angina/angina-like symptoms
D- drop in SBP >/= 10 mmHg with inc. in work rate
E- excessive rise in BP: systolic >250 mmHg, and/or diastolic >115 mmHg
S- shortness of breath, leg cramps, claudication

Question 10

What are additional reasons to stop an Exercise Test?

P HR S

Answer 10

P- signs of poor perfusion (light-headedness, confusion)
HR- failure of HR to inc. with inc. intensity
S- subject requests to stop

Question 11

What are the 2 reasons for Exercise Testing?

Answer 11

Functional- determine level of fitness for training/ prescription purpose
Diagnostic- find underlying diseases/issues (stress-test)

Question 12

What is the protocol for Balke treadmill test?

Answer 12

• increase GRADE
• speed remains constant
• no one protocol for speed, but must remain constant (standard 3mph)

Question 13

What is the Treadmill Submax protocol?

Answer 13

Progress subject up to 85% of APMHR

Constant increase in METs/stage

Question 14

Astrand Protocol

Answer 14

Goal: obtain HR btw 125-170 (< 125 HR-VO2 relationship is weak; > 170 = out of submax test range)
Single stage, 6 minutes at 50 rpm; Age correction factor
Get: work rate, HR, and predict VO2 via nomogram

Question 15

YMCA Protocol

Answer 15

• multi-stage = 3 minute stages
• next stage dependent on HR of 1st stage
• HR taken each min, BP every 3rd
• adv= longer, slightly more VIG, more data points

Question 16

Bruce Treadmill Protocol

Answer 16

• Most used, 3 min stages
• increase GRADE and SPEED
• utilize HR and workload data from 2+ stages to estimate VO2max
• good for younger, more physically active

Question 17

What is the General Method for Max Testing?

Answer 17

Goal of 8-12 minutes to reach max capacity

> 12 minutes, fatigue becomes limiting factor

Question 18

Cycle vs. Treadmill

Answer 18

Cycle: safer, easier for measurements, non weight-bearing, convenient
-Astrand and YMCA
Treadmill: familiarity (used to walking), may yield larger VO2 (unless trained on cycle)
- Balke and Bruce
