Chapter 10 Flashcards
Why is it important to do fitness training?
To ensure a proper exercise program is prescribed
How long should you time a client’s resting heart rate?
60 seconds
What is the most accurate technique for counting heat rate at rest and during exercise?
Chest auscultation using a stethoscope
What artery is the best to palpate when checking heart rate?
The radial artery located at the wrist or carotid artery in the neck
What is considered a normal resting heart rate?
60-100 beats per minute. however, a highly trained athlete can have a resting heart rate as low as 40 bpm
What is considered to be a normal blood pressure reading?
120/80 mm/Hg
(T/F)? if a blood pressure measurement needs to be repeated, you should wait approximately 60 seconds or more with the cuff completely deflated to allow circulation to return to normal.
True
What does the term body composition mean?
Dividing the body into two components, fat weight and lean body weight.
A high fat weight is a risk factor for what?
Disease, cancer, diabetes, and other health problems
How do you calculate body mass index?
BMI - divide the body weight in kilograms by the height in meters squared (kg/m2)
What determines how an individual’s subcutaneous fat levels are distributed?
Age, gender, body type, and activity levels
Where do most females store fat?
Triceps, hips, and thighs
The waist-to-hip-ratio is effective in measuring what?
Shows the individual’s fat distribution as well as their risk factors of mortality and morbidity
(T/F)? in the waist-to-hip-ratio, the hip measurement should be smaller in circumference than the waist measurement.
False; the waist measurement should be smaller in circumference than the hip measurement.
What is a normal waist-to-hip-ratio for a male between the ages of 17-39?
0.90
What is the estimated accuracy range of hydrostatic weighing?
2.5%
How would an individual take a skin fold measurement on the axilla?
Vertical fold on the midaxillary line at the level of the xiphoid process
What is the standard three site skin fold formula for a man? Woman?
Chest, abdomen, thigh
Triceps, Suprailiac, thigh
The bioelectrical impedance analysis technique is based on what assumption?
Tissues high in water content will conduct electrical currents with less resistance than those with little water. because adipose tissue contains little water, fat will impede the flow of electrical current.
What is the estimated accuracy range of BIA?
4%
When using the BIA technique how long should a person fast before being tested?
Eating and drinking should be avoided for 4 hours prior to testing.
What is the purpose of the sit and reach test?
The test measures flexibility of the erector spinae muscles, hamstrings, upper back and calves.
What position creates maximal compressive forces on the intervertebral disks?
A seated fully flexed position
How do you score the client on the sit and reach test?
The client’s score is the best of three and can be compared to the norms of their sex and age.
