EXSC 410 EXAM QUESTIONS ANDANSWERS
5 components of health related fitness - Answer-cardiorespiratory fitness, body
composition, muscular strength, muscular endurance, flexibility
how can we test aerobic fitness? - Answer-maximal and sub maximal aerobic fitness
tests
what is a submaximal test - Answer-- estimates VO2 max
- cheaper
- less time consuming
- better for high risk individuals
- less experienced technicians required
- can test many participants at once (step test)
what is a maximal test - Answer-- VO2 Max test
- perform action until volitional exhaustion
- can be dangerous/not possible for high risk populations
- expensive
- needs experienced personnel to administer
what component does the ebbeling test teach us about? - Answer-cardiorespiratory
fitness
what type of test is the ebbeling test? - Answer-submaximal aerobic test
assumptions of submaximal aerobic testing: - Answer-- steady state is reached
- 220-age = HRmax
- HR is linearly related to VO2 and Workload
- aerobic fitness is the limiting factor
- subject is in appropriate state for exercise (no HR altering medications, illnesses, etc.)
- mechanical efficiency is the same for everyone
Submaximal Lab Tests: - Answer-- YMCA Bike
- Astrand Cycle Test
- Ebbeling Treadmill Walk
- Step Tests
- Non-exercise models
Submaximal Field Tests: - Answer-- 12 minute run
- one mile walk
Graded Aerobic Exercise Tests - Answer-- bench stepping
- cycle ergometer
, - treadmill
bench stepping test - Answer-- simple to conduct
- can test large populations
- different protocols have different step heights
cycle ergometer test - Answer-- can be good for people with balance issues
- could result in muscular fatigue over aerobic fatigue (not good for accurate results)
aerobic treadmill tests - Answer-- everyone walks so participants are already trained
- most likely that aerobic will be the limiting factor
- need a treadmill
- difficult for people with balance issues
variables measured during aerobic testing: - Answer-- HR
- BP
- power output
- RPE
- time
- distance
rating of perceived exertion - Answer-scale of 6-20, number participant picks should
correlate with their HR, 6=60bpm
limitations of submaximal testing - Answer-- HRmax variability (not always 220-age)
- HR linearity variability (not always perfectly linear relationship)
- cycle economy variability (not everyone cycles regularly)
- submit tests estimate VO2 max, they don't measure it
indications for stopping a submax test: - Answer-- chest pain
- drop in SBP greater than 10mmHg
- excessive rise in SBP greater than 250mmHg or DBP greater than 115mmHg
- shortness of breath
- failure of HR to increase w/ workload
- noticeable change in heart rhythm
- individual requests to stop
- failure of testing equipment
Ebbeling Protocol - Answer-1. calculate HRmax and 50% and 70% of it
2. take resting HR and BP
3. subject warms up (2.0-4.5mph) need to reach (50-70% HR)
4. if not at HR range after 2 min, do a 3rd
5. If not at HR range after 3rd min increase speed and repeat warm up
6. after warm up, increase grade to 5% and keep speed same
7. subject walks for 4-5 minutes, should reach steady state.
8. record HR every 30 seconds during testing stage
