Chapter 14 Flashcards
What is atherosclerotic heart disease?
The narrowing of the coronary arteries that supply the heart muscle with blood and oxygen.
What is ischemia?
an inadequate blood supply to an organ/part of body, particularly the heart
What does metabolic equivalent mean?
It refers to the energy you use at rest compared to the energy used during exercise.
A value of 7 METs is 7 x the energy used at rest.
How many sets/reps should those with CAD start on and how often?
One set of 12-15 reps using 8-10 exercises that target major muscle groups 2x a week.
What level on the 6-20 RPE scale should those with CAD not exceed?
11-14
What signs signal termination of session?
angina dyspnea lightheadedness/dizziness pallor rapid HR above established targets
How do you know a client is hypertensive?
Their BP reads as 140/90 or they take antihypertensives.
How much activity should prehypertensive and hypertensive individuals participate in?
at least 30 mins of regular activity for at least 5 days a week
What resistance training is recommended for prehypertensive/hypertensive clients?
Those using low to moderate resistance and high reps as opposed to heavy lifting
What type of exercise/contraction should be avoided for pre/hypertensive clients?
Isometric exercises
What two medications can alter heart rate response and cause orthostatic hypotension and post exercise hypotension?
beta blockers
calcium channel blockers
An exercise session should be discontinued if the SBP or DBP rises to ______ or ____ mmHg or if the SBP fails to _________.
250 or 115
or if the SBP fails to increase.
What are the warning signs of a stroke?
- sudden numbness or weakness of face, arms, legs
- confusion or trouble speaking/understanding others
- trouble seeing
- walking problems, dizziness or loss of balance and coordination
- severe headache with no known cause
What duration of walking should someone with PVD start at and progress to?
They should start with 20-30 mins and progress to 30-60 mins.
Where is cholesterol manufactured in the body and what foods is it prominent in?
It is manufactured by the liver and found in dairy products, meat and eggs.
What is an effective means of improving lipid profiles in many people?
The combination of exercise and dietary changes that lower body weight.
What fasting plasma glucose levels suggests diabetes and prediabetes?
Diabetes = > or equal to 126mg/dL Prediabetes = 100-125 mg/dL
What pre-exercise blood glucose levels should signal you to avoid/postpone exercise?
If the pre-exercise glucose is greater than 300 mg/dL alone or over 250 mg/dL with ketosis.
Most Type 1 Diabetes clients can comfortably exercise at an intensity between 55-75% of capacity or at an RPE of __ to __.
11-14
What are the exercise guidelines for Type 1 Diabetics?
To allow 5-10 mins of proper warm up and cool down.
To progress to 30 mins or more of exercise at an RPE of 11-14 on the 6-20 scale.
What are the exercise guidelines for Type 2 Diabetics?
To allow 5-10 mins of proper warm up and cool down.
To perform aerobic exercise at low-moderate intensity/11-16 RPE for 40-60 mins 5 or 6 days a week.
Low-mod resistance training consisting of 8-12 reps for 8-10 different exercise 2x a week is also recommended.
What is metabolic syndrome characterized by?
abdominal obesity dyslipidemia increased BP insulin resistance prothrombotic state proinflammatory state
The AHA and NHLBI recommend that metabolic syndrome can be identified with 3 or more of what components?
- elevated waist circumference (men ≥ 40 inches / women ≥ 35 inches)
- elevated triglycerides (≥ 150 mg/dL)
- reduced HDL cholesterol (men < 40 mg/dL / women < 50 mg/dL)
- increased BP 130/85
- elevated fasting blood glucose (≥ 100 mg/dL)
What is the primary treatment objective for metabolic syndrome?
To reduce the risk for developing cardiovascular disease and type 2 diabetes.
ACSM recommends that overweight and obese individuals should accumulate how many mins of physical activity per week?
200-300 mins
At what intensity should a deconditioned individual with METS begin at and progress to? And how frequently?
They should begin at a low intensity and gradually progress to moderate levels such as 40-75% of VO2 reserve or an RPE of 9-13.
They should begin with a frequency of 3-5 times a week.
