Exercise Testing for Health and Physical Fitness Flashcards
Work
- Formula = ?
- Unit of measure = ?
Exercise Testing
- Work = Force exerted over a distance
- Work = force × distance
- Unit of measurement: joule (J)
- 1 joule = 1 Newton (N) of force over 1 meter
Power
- Formula = ?
- Unit of measure = ?
Exercise Testing
- Power / “Explosive Strength” = The rate at which work is performed
- Power = force × distance / time
- OR Power = force × velocity
- Unit of measurement: watts (W)
- 1 W = 1 J/s
Min. VO2max needed for living = ?
Exercise Testing
Min. VO2max needed for living = 13 mL·kg·min-1
Cycle Ergometry Protocols
Advantages over treadmill = ?
Exercise Testing
- VO2max is typically 5-25% lower than in treadmill running
- Advantages over treadmill
- Used for cyclists & triathletes to monitor sport-specific fitness
- Appropriate for those w. postural instability, arthritis, etc.
- Easier to monitor blood pressure
- Fewer ECG artifacts
HR has general linear relationship to = ?
Exercise Testing
- HR has general linear relationship to:
- Mechanical power output
- Workload
- Exercise intensity
Normal Values for Resting HR
- Men
- Low = ?
- Average = ?
- High = ?
- Women
- Low = ?
- Average = ?
- High = ?
Exercise Testing
- Normal Values for Resting HR:
Electrocardiogram (ECG) Measurement
Normal or abnormal cardiac function is indicated by waveform = ?
4
Exercise Testing
- Electrocardiogram (ECG) Measurement = Used when stress testing people w. signs or risk for CV disease.
- Waveforms represent contraction & relaxation of heart chambers
- Normal or abnormal cardiac function is indicated by waveform:
- Height
- Width
- Spacing
- Shape
Perceived Exertion Measurement
Exercise Testing
Perceived Exertion Measurement:
- Intended to correspond (when multiplied by 10) to:
- HR
- Oxygen uptake
- Should be obtained from subject in last 15 sec of each stage of GXT
RPE Scale and Associated Physiological Responses
- RPE 11 = ? % Max HR / ? % VO2max
- RPE 13 = ? % Max HR / ? % VO2max
- RPE 15 = ? % Max HR / ? % VO2max
- RPE 17 = ? % Max HR / ? % VO2max
Exercise Testing
Cardiovascular Endurance Tests
Terminate Test when = ?
Exercise Testing
Test Termination Criteria:
- Angina or chest pain indicating myocardial ischemia
- Abnormal blood pressure response
- Abnormal ECG response
- Discomfort or pain in extremities indicating intermittent claudication
- Dyspnea, or difficulty in breathing
- Dizziness or syncope
Lactate Threshold
- Untrained people occurs at about ? % VO2max
- Athletes occurs at ? % of VO2max
Exercise Testing
- Untrained people: occurs at about 50% VO2max
- Athletes: occurs at 80-90% of VO2max
- Cause of excessive rate of lactate release:
- Greater reliance on carbohydrate instead of lipid metabolism
- Recruitment of fast-twitch muscle fibers
- Stimulation of sympathetic nervous system
Ventilatory threshold = ?
Exercise Testing
Ventilatory threshold(VT1) refers to the point during exercise at which ventilationstarts to increase at a faster rate.
Anaerobic capacity tests = ?
Exercise Testing
Anaerobic Capacity: Most tests quantify performance in tasks relying on ATP synthesis
- Wingate test = 30-second test on cycle ergometer
- Margaria step test = running up staircase as fast as possible.
- Anaerobic treadmill test = running at 20% grade & 8 mi·hr-1
- Vertical jump test = jumping & reaching as high as possible
- Running sprint test = amount of time to cover given distance
What factors affect anaerobic power and speed tests ?
Exercise Testing
Factors Affecting Anaerobic Power and Speed Tests:
- Motivation to perform at one’s best
- Skill at performing movements
- Degree of coordination
- Muscle-fiber-type composition
- Body composition
The FITT principle is an acronym that represents = ?
Exercise Testing
FITT principle =
- Frequency
- Intensity
- Time
- Type
