Question 1

What is the recommended minimum min of exercise per week for adults?

Answer 1

-150 min/week

Question 2

Purposes of maximal VO2 tests

Answer 2

• to diagnose coronary artery disease
• test responses to conditioning programs
• test motivation for activity
• accurately measure VO2 (meaning also accurate lactate and MLSS thresholds)

Question 3

Types of pain in exercise/sports

Answer 3

• Physiological induced pain
• pain from contact (getting hit)
• Emotional pain (learning how to not react by stimuli in order to stay focused and achieve your goal)

Question 4

What are some assumptions of sub maximal lab tests?

Answer 4

• can lead to 10-20% error
• HR and VO2 have linear relationship
• max HR for a given age is the same

Question 5

Advantages of sub maximal tests

Answer 5

• large numbers in short amount of time
• cheap

Question 6

Disadvantages of sub maximal tests

Answer 6

• variability in max HR
• HR can be affected by external factors
• VO2 changes depending on the modality of the test (most have a higher VO2 max while running on treadmill vs running/cycling)

Question 7

What are some pre-test controls before any aerobic power test?

Answer 7

• HR under 100
• Resting BP below 144/94 and above 80/50
• No alcohol 6 hours before test
• No caffeine 2 hours before test
• no heavy meal within 3-4 hrs

Question 8

Criteria for stopping test

Answer 8

• HR reached 85% of HR max
• fatigue/pain
• client requests to stop
• angina
• rapid ventilation at low work rates
  -SBP above 250
• DBP above 129
