24
Q

What’s considered a low risk for waist to hip ratio for men and woman?

A

.95 or lower for men
.80 or lower for woman

25
What’s considered a high health risk for waist to hip ratio for men and woman?
1.0 or higher for men .86 or higher for women.
26
How do you calculate the waist to hip ratio (WHR)?
WHR = Waist measurement divided by Hip measurement
27
Gluteal fold
The area where the fold of the buttocks joins the back of the thigh
28
Where does a personal trainer take the skinfold measurements?
8 places on the body:
29
What are some things to keep in mind when using calipers/skin fold measurements?
30
Jackson and pillock 7-site protocol
Measures the thickness of skin folds at seven different places within the body to estimate body fat percentage.
31
Jackson and pollock 3- site protocol
Measures the thickness of skin folds at three different places within the body to estimate body fat percentage.
32
Four-site Durnan- Womersley protocol
Measures the thickness of skin folds at four different places (biceps, triceps, subscapular, and suprailiac) within the body to estimate body fat percentage.
33
How is the body fat percentage calculated with the Durnin - Womersley skin folds measurement?
Add the totals of the four skin folds sites and then find the appropriate sex and age categories for the body composition in the Durnin-Womersley body fat percentage chart:
34
How do you find the body fat percentage for the Jackson and pollock seven site and three site protocol?
Once the sum of the SKFs (skin folds measurements) have been recorded, various online resources can be used for estimating body fat percentage.
35
When is the Durnin- Womersley formula best used?
For individuals between the ages of 17 and 49 years of age and may not be as applicable for older adults. A potential advantage is that it only requires measurements for the upper body; it does not require an individual to wear shorts for a thigh measurement.
36
What is SFM (skin fold measurement) is considered the most accurate?
The seven site method
37
Bioelectrical impedance analysis (BIA)
A body composition assessment technique that estimates body fat percentage by measuring the resistance to the flow of electrical currents introduced into the body.
38
What are the BIAs (bioelectrical impedance conduction) limitations?
These include any event where the body either retains or loses water. Examples: fluctuating hydration levels, dehydration, extreme temperatures, heavy sweat rates, the use of diuretic, and even the presence of urine in the bladder volume.
39
Archimedes’ principle
The assumption stating that the volume of fluid displaced is equivalent to the volume of an object, fully immersed in that fluid or to the specific fraction of the volume below the surface.
40
What is the field of study of the measurement of living humans for purposes or understanding human physical variation in size, weight and proportion?
Anthropometry
41
Which principle assumes that the volume of fluid displaced by an object is equivalent to the volume of the object, fully immersed in that fluid or to the specific fraction of the volume below the service?
Archimedes’ principle
42
Mitochondria
The part of the cell that uses the nutrients to create energy for the cell; commonly known as the powerhouse of the cell.
43
Vo2max
The most valid measurement of aerobic fitness is a VO2max test. Oxygen consumption (VO2) is a measure of body’s usage rate of oxygen; it’s the difference between inspired and expired oxygen. It reflects the body’s ability to deliver oxygen to the exercising muscles and use it in mitochondria to manufacture energy aerobically. VO2max, or maximal oxygen uptake, measures the body’s upper limit of oxygen use, which is sometimes called peak VO2. •a higher VO2 max score reflects greater oxygen utilization and a greater capacity for physical work. •VO2max usually peaks at around ages 25 years to the early 30s, but it is highly trainable, implying that an active person in their 40s could have a higher VO2max than during their sedentary 20s. •VO2max decreases by approximately 5% per decade in fit individuals (an average of .5% per year) and around 10% per decade in unfit individuals (an average of 1.0% per year)
44
Ratings of perceived exertion
A subjective rating of perceived exertion (RPE) is a technique used to express or validate how hard a client feels that they are working during exercise.
45
YMCA 3 min step test
Cardiorespiratory assessment that assesses the aerobic fitness of deconditioned clients by having them complete 3 mins of continuous stepping in and off a 12-in (30-cm) box. Considered suitable for low risk, apparently healthy, non athletic adults. Cardiorespiratory fitness is evaluated from the recovery heart rate (RHR) rather than from an estimate of VO2max.
46
Rockport walk test
An aerobic test for deconditioned individuals or those of low fitness levels in which they are instructed to walk as fast as possible and have their pulse taken immediately after completing 1 mile.
47
1.5-mile 2.4 km) run test
An aerobic test that measures cardiorespriatory endurance by having the participant cover the distance of 1.5 miles in a short a time as possible.
48
Talk test
An aerobic test that measures the participants ability to talk or hold a conversation during an activity at various intensity levels.
49
Ventilatory threshold 1 (VT1)
The point at which the body uses an equal mix of carbohydrate and fat as fuel sources
50
Steady-state (SS) heart rate
Any stage at which the physiological response of heart rate from the cardiovascular system becomes relatively constant in relation to the amount of work being performed. (The heart rate response matches the level of work being performed).
51
The Ventilatory threshold (VT1) Test
An incremental test performed on any device (treadmill, bicycle) that gradually progresses in intensity level and relies on the interpretation of the way a person talks to determine a specific event at which the body’s metabolism undergoes a significant change. Aerobic test that aims to estimate thru nest of the body’s usage of a balance of fuels (50% fat, 50% carbs). Because it is an aerobic test, Steady state (ss) heart rate must be attained before any assessment of talking is collected.
52
Ventilatory threshold 2 (VT2)
The point where glucose provides nearly all the energy of the activity.
53
Anaerobic energy systems
Energy systems used to perform work in which glycogen is converted to glucose and oxygen is insufficient to break down pyruvate and create adenosine triphosphate.
54
Ventilatory threshold 2 (VT2) talk test
Measures the level at which the body can work at its highest sustainable steady-state intensity for more than a few minutes. At this level the body relies heavily on the anaerobic energy systems that begin to overwhelm the blood’s lactic acid buffering capacity. At this level the individual cannot respond to a question responds “no”.
55
What is the most valid measurement of aerobic fitness?
VO2max
56
Which term defines the degree to which a test specifically measures what it is intended to measure?
Validity
