Lecture 5

Question 1

Purpose of fitness testing:

Answer 1

• educating about present fitness status relative to health-related standards, and -age/gender norms
• provide data that will assist in the development of ExRx
• collecting baseline and follow up data to evaluate effectiveness of ExRx
• motivate participants by establishing goals
• stratifying risk
• identify readiness to resume training
• research questions
• strengths and weaknesses of participant

Question 2

Risk assessment:

Answer 2

identify hazards
decide who might be harmed and how*
evaluate risk and decide whether existing precautions are adequate or more should be done
record significant issues*
review assessment and revise if necessary

Question 3

Equipment hazards:

Answer 3

Electrical hazards *
Entrapment hazards
Falls or trips

Question 4

Physiological state or client hazards:

Answer 4

Cardiovascular complications
Fainting
Vomiting*
Musculoskeletal injury

Question 5

Environmental hazards

Answer 5

Modifications to env – heat, cold, hypoxic, gas mixtures

Question 6

Informed consent:

Answer 6

Explain purpose of test
Description of procedures, time commitments
Identify/describe risks, discomforts, benefits
Statements regarding confidentiality, anonymity, privacy
Id contact person regarding questions
Statement that it is voluntary, withdraw without fear of sanction anytime

Question 7

Pre-test instructions:

Answer 7

Wear comfy, loose fitting clothing
Drink plenty fluids 24hour prior
Avoid food, tobacco, caffeine for x hours prior
Avoid alcohol, strenuous ex 24 hr prior
Get adequate sleep night before (6-8hrs)

Question 8

Prior to participant arrival:

Answer 8

Have all forms, paper work required ready
Calibrate* equipment
Organise equipment and test space so test can follow in sequence w/out stressing same muscle group repeatedly
Ensure informed consent is obtained
Set room temp between 20-23deg* humidity <60%

Question 9

Test order*

Answer 9

1 Resting measurements – HR rest, BP rest, ht, wt, body comp
2 cardiorespiratory endurance
3 muscular fitness
4 flexibility

Question 10

Selecting appropriate tests

Answer 10

Energy system
Mode of ex
Muscle group
Mvmt type

Question 11

How can you achieve standard conditions in each case?

Answer 11

Provide meals, food ex diary, pedometers, HR monitor

Question 12

Timing devices:

Answer 12

Chronometers (stopwatch)
Counters e.g. rpm
Metronomes
*+/- 1rpm = ~2% error in Watts (1.3% error in VO2)
* +/- 6rpm = ~10% error in Watts (8% error in VO2)

Question 13

Cycle ergometer advantages

Answer 13

Safer-less client apprehension
Easier for blood sampling
Improved audibility for BP assessment
Reduction motion artifact for ECG
Space efficient
Less expensive

Question 14

Cycler ergometer disadvantages

Answer 14

Less familiar mode of ex
Leg fatigue may limit ex before cardiopulmonary limitation is reached
Smaller total muscle mass decrease VO2 max
Work rate can be intrinsically regulated

Question 15

Treadmill advantages

Answer 15

Most familiar motor patter
Large muscle mass -> larger vo2 max
Easy to calibrate

Question 16

Treadmill disadvantages

Answer 16

Greater safety risk and client apprehension
Increased motion artifact and noise
More difficulty for collection of blood samples
Less space efficient
