EXSS 2004 Chapter 10
Equipment and assessment in exercise science
Terms in this set (15)
1. Why should the type of ergometer (i.e., treadmill or cycle) used during testing be matched to the exercise mode of the individual being tested?
The type of ergometer should be based on the individual's primary mode of exercise. The treadmill is good for people who generally do walking or running. Recombinant cycles are good for people who are overweight, disabled, need extra support, or already cycle frequently.
2. A metabolic measurement cart is used to make assessments of what physiologic measure?
Cardiovascular and Pulmonary function
volume of air inhaled and exhaled
3. The measurement of lung function provides an assessment of what two broad categories of pulmonary disease?
Restrictive Lung Disease: decreased lung capacity due to inflammation, scarring, or abnormalities in the muscles or skeleton of the chest wall
Obstructive Lung Disease: narrowing of the passageways of the lungs, which makes exhaling difficult (asthma, chronic obstructive pulmonary disease)
4. An ECG machine measures what aspect of cardiovascular function?
Detects and records the electric impulses of the heart during and between contractions
5. An EMG machine measures what aspect of muscular function?
Electric activity of skeletal muscles during and between contractions.
6. An isokinetic dynamometer controls the speed of muscle contraction and makes a measurement of what muscle function?
Muscle force (torque) during isometric and isokinetic movement of joints
7. Describe the basic scientific principle associated with the use of MRI and MRS.
MRI: uses a strong magnetic field, radio frequency pulses, and a computer to produce detailed pictures of body structures. The MRS is similar to that of the MRI, only in the MRS technique the noninvasive measurement of tissue substrates and metabolites can occur.
8. Dual energy X-ray absorptiometry can be used to provide a quantitative assessment
of what three body components?
Lean Mass, Fat Mass, and Skeletal Mass.
9. What are the three most commonly used instruments for the determination of free- living physical activity and energy expenditure?
Whole-Room Indirect Calorimeter, Doubly-Labeled Water, Accelerometers and Pedometers
10. What is the conceptual basis for using bioelectric impedance analyzers to measure body composition?
Lean body mass is 50%-70% water, where fat body mass is 15%-20% water. When a low voltage electric current is sent through the body, it travels through body mass faster if the body mass has more water. So, by measuring how fast an electric current runs through the body and considering height and weight, it is possible to come up with a person's body composition.
11. The principle that a certain percentage of total body fat lies directly beneath the surface of the skin allows for the use of which technique for the assessment of body composition?
Skinfold assessment using skin fold calipers.
12. What are the two types of thermotherapy and how does each type work to enhance rehabilitation from injury.
Cryotherapy: reduces temperature in injured area, tissue metabolism, inflammation, bloodflow, paint, and muscle spasm.
Heat Therapy: aids in recovery by increasing blood flow, and decreasing muscle and joint soreness and stiffness.
13. High-speed motion capture systems are often used to assess what aspect of motor performance?
Body and limb movements
14. Electroencephalography (EEG) provides the assessment of what physiologic measure?
Electric activity produced by the brain
15. What is the difference between quantitative and qualitative instruments in the measurement of behavioral and psychological assessments of exercise and sport psychology?
Quantitative instruments often involve questionnaires or psychological inventory that give insight into the individuals chronic and acute physical activity
Qualitative research might involve life histories, case studies, or a mixture of different approaches
