40
Systematic error
situations that result in a unidirectional change in scores on repeated testing
41
Examples of Systematic error
bias, learning, fatigue
42
Random error
variability both increases and decreases test scores on repeated testing
43
Examples of Random error
imprecision, biological
44
Validity
Does a test, instrument, etc. measure what it is supposed to measure?
45
Face Validity
Can be claimed when the measure appears to obviously assess the target variable or performance
46
Content Validity
The attempt to measure the desired parameter or a defined domain of content. Is your evaluation more than the sum of its parts?
47
Construct Validity
Can be claimed when the measures permit inferences to be made about an underlying trait(s)/abilities.
48
Criterion Validity
Evaluate the performance of your test against some criterion (i.e. usually another test which seeks to measure the same construct)
49
Concurrent validity
Can be claimed when a test measure is similar to a criterion (standard) or previously validated test measure.
50
Discriminant validity
“Have all of your athletes run a mile – the ones who come last will be your most powerful athletes
51
Predictive validity
Can be claimed when the measure taken, successfully predicts the criterion measure of a gold standard
52
Reliability
How consistent is a test or measure?
53
Analysis of Variance (ANOVA)
The inferential test of mean differences across trials. Assessment of systematic error. It detects how much change occurred from one trial to the next
54
Intra Class Correlation (ICC)
A relative measure of reliability in that it is a ratio of variances. Applied to specific populations
55
Systematic Bias
(Improvement) mean of the diff. scores. Bias should be minimized before calculating Typical Error.
56
Resting metabolic rate
Consisting of basal and sleeping conditions plus the metabolic cost of arousal (60-75%)
57
Thermogenic effect of feeding
Breaking down food consumed (10%)
58

assessing aerobic power's golden standard is
68

69
Secondary criteria for determining aerobic power (VO2max)

O2 sensor CO2 sensor Volume sensor
72
VO2 formula F1N2
79.04%
73
VO2 formula F1O2
20.93%
74
Absolute VO2
The total volume of oxygen taken up by the body (L/min)
75
Relative VO2
The volume of oxygen taken up by the body relative to that person’s body weight (ml/kg/min)
76
Reasons for terminating a VO2max test
○ Drop in systolic BP of 10 mmHg with increase in workload. ○ Chest pain or angina. ○ Increasing nervousness (including dizziness, near fainting). ○ Signs of poor perfusion (cyanosis or pallor). ○ Abnormal ECG recording (if using). ○ Hypertensive response (> 250/115 mmHg). ○ Cramping, signs of extreme fatigue. ○ Failure of equipment
77
Bruce VO2max test is better for
older populations
78
Astrand VO2max test is better for
athletes
79
VO2max used the most
Bruce
80
Diagnostic stress tests
coronary artery disease & symptoms such as chest pain, shortness of breath or lightheadedness.
81
Functional stress tests
To assess a procedure that was used to improve coronary artery circulation
82
Prognostic stress tests
Assessing patients with risk factors
83
Absolute contraindications of exercise
➢ Acute MI (within 2 days) ➢ Acute pericarditis, myocarditis ➢ Pulmonary edema ➢ Severe aortic stenosis ➢ Dissecting aneurysm ➢ Hemodynamically unstable arrhythmia
84
Walking relative VO2 equation
VO2= (0.1*S) + (1.8*S*G) + 3.5
85
Treadmill relative VO2 equation
VO2= (0.2*S) + (0.9*S*G) + 3.5
86
Liability perspective
1. Be a professional 2. Pre-screening actions and intentions are important 3. Pre-screening paperwork is important 4. Don’t make it up as you go along
87
Risk mitigation perspective
1. Ask before you do 2. Explain before you do 3. Listen, answer questions 4. Get real acknowledgement from participants
88
Hyperpnea
Ventilation to match metabolic demand
89
Hyperventilation
Ventilation to remove excess CO2
