Unit 1 quiz Flashcards
Respiration is caused by air pressure differences between the lungs and atmosphere
true
kinetics is the study and description of motion
false
arteries carry blood toward the heart, veins carry blood away from the heart
false
force is a linear effect that can be described as a push, pull, or tendency to distort
true
the AV node delays electrical conduction through the heart about .13s allowing for arterial contraction to ventricular depolarization
true
biomechanics is the study and application of the motion of living organisms using the branch of physics known as mechanics
true
the heart is located posterior to the vertebra and anterior to the sternum
false
one function of the cardiovascular system is to remove metabolic waste
true
kinematics is the study of forces and torques that cause movement
false
the heart valves function to keep blood flowing in two directions
false
Under cold stress the body shunts blood to the skin which transfers heat from the core and warms exposed cold areas like the face hands
false
endurance athletes do not need to ingest more water or fluids when competing and a good guidance is to drink water when thirst begins
false
Acute resistance training has no effect on blood pressure
false
one physiologic adaptation induced by resistance training is an ability to recruit a greater percentage of motor units when required
true
the oxidative phosphorylation metabolic pathway can create ATP using carbs, fats, or proteins
true
dietary fiber helps with digestive health but is not impact blood cholesterol
false
Routine consumption of various nutritious foods among the basic food groups practically ensures adequate intake of vitamins and minerals
true
high density lipoprotien (HDL) cholesterol increases the risk of coronary artery disease
false
Cardiovascular drift occurs when heart rate increases despite steady state exercise workloads
true
Anaerobic glycolysis yield a total of 4 to 5 ATP molecules
false
transient ischemic attacks (tia) have neurologic symptoms that last more than 24 hrs
false
the ability to recruit high threshold motor units is impaired after deconditioning
true
it is currently recommended that otherwise healthy individuals perform 30 minutes of moderate- intensity aerobic activity per day at least 5 days per week, supplemented by an increase in daily lifestyle activity
true
the most recent national cholesterol education program recommendations are that all non HDL-C levels should be less than 130mg/ day
true
during the initial hours after an acute myocardial infarction, the heart typically experiences decreased systolic function
true
acceptable body fat percentage in prepubescent children is different for males and females
false
peripheral artery disease PAD refers to inhibited blood flow through noncoronary arteries such as the femoral, tibial, illiac, abdominal aorta, renal and mesenteric arteries
true
muscle atrophy as a result of deconditioning is most severe in muscles involved in weight bearing and postural control (thigh, calf muscle groups)
true
fat free mass (FFM) remains relatively constant throughout adulthood
false
anaerobic power declines to childhood levels by age 65 and does not improve with training after 60
false
an assumption of risk by a client or patient simply allows the exercise professionals to perform other procedures outside their typical realm of duties when working with a patient or client
false
The limitation of the PAR-Q preparticipation screening is that it can only identify those who are high risk
True
exercise prescription in patients with known cardiovascular disease may be done without approval and input from a physician
False
in examining exercise testing procedures and recommendations for structured physical activity provided to clients, it is important for professionals to understand how the law of contracts affects their relationships with clients
True
physician approval is not needed to safely start an exercise program in patients with osteoporosis
false
increased numbers of untoward events will result in negligence claims
true
the modified research council questionnaire for assessing the severity of breathlessness is a useful preparticiaption screening tool for assessing which activity patterns bring on breathlessness in patients with chronic heart failure
false
documentation is not important to many aspects of risk management, just the verification of adherence to standards
false
generally it is prudent for the elderly to obtain physician clearance to participate in an exercise program
true
when negligence claims are asserted, the critical question centers on whether an exercise professional provided service in accordance with the so- called standard of care
true
