Final-cardiovascular testing

Question 1

assumptions of V02 max from submax exercise

Answer 1

Steady state HR is obtained for each work rate

• linear relation b/w work and HR
• the dif b/w actual and predicted HR is minimal
• subject is not on any meds

Question 2

General indications for stopping an exercise test (ACSM)

Answer 2

• onset of angina symptoms
• drop in SBP >10
• excessive rise in BP
• shortness of breathe
• failure of HR to increase
• requests to stiop

Question 3

Test termination criteria CSEP

Answer 3

• reaches 85% of 220-age
• asks to stop
• shows signs of physiological distress
• canot maintain cadence

Question 4

Minimum vo2 max for independent living and how much does it decline per decade

Answer 4

15-20ml/kg/min

declines 4-5ml/kg/min per decade

Question 5

ACSM walking equation considerations (page 3 slideset 8)

Answer 5

convert mph to m/s (mph x 26.8)
convert grade to decimal form (10% to .1)
above 5mph equation starts with 0.2

Question 6

How to calculate acsm cycling equation

Answer 6

1. calculate workrate- (3kg) (60rpm) (6m/rev) = x kg min
2. xkgmin/ 6 = x watts

put xwatts into vo2 cycling equation

Question 7

how much does handrail holding affect VO2

Answer 7

25-35% less work when holding rail

Question 8

calculation of caloric cost of activity (example on page 5 slideset 8)

Answer 8

vo2 * 5= energy expenditure in kcal/com

Mets* 3.5* body weight (kg)/200= kcal/min

Question 9

advantages of submaximal testing

Answer 9

• safer
• controlled pace
• not population specific
• quick
• cost effective
• dont need highly trained personnnel
• can do mass testing

Question 10

disadvantages of submaximal testing

Answer 10

1. Vo2 max is not directly measured (10-20% off)

2. dont get a measure of true max HR

Question 11

Advantages and disadvantages of max tests

Answer 11

adv
1. more accurate

dis

• motivation is factor
• more risk
• time
• cost

Question 12

How many cals does an 80kg man burn while running at 8mph with 2% incline for 30 mins

V02=(.2)(speed)+(.9)(grade)(speed)+3.5
cals/min= Vo2 max(l/min) *5

Answer 12

(0.2)(826.8)+(.9)(.02)(826.8)
=50.3ml/kg/min

50. 3*80/1000 *5
51. 1cal/min

30 mins=603kcal

Question 13

The max rate of oxygen uptake during aerobic exercise reflects these 2 things

Answer 13

1. the capacity of the heart, lungs and circulatory system to transport and deliver oxygen to working muscles
2. utilization of oxygen by muscles during ex

Question 14

What is Ve/MVV and what do healthy subjects have and chronic pulmonary disease subjects

Answer 14

-ratio of max minute ventilation during exercise to maximal voluntary ventilation at rest

health- achieve 60-70%
chronic- may achieve 100%
