adenosine triphosphate (ATP)

the immediate source of energy for all cellular activity, including the contraction of muscle fibers is ?

the nonoxidative pathway

which bioenergetic pathway is sometimes called the "anaerobic" pathway?

the oxidative pathway

the primary advantage of which bioenergetic pathway is that it can produce large amounts of ATP to sustain prolonged exercise, without producing fatiguing by products?

sarcoplasmic reticulum

within a skeletal muscle fiber, large amounts of calcium are stored in the?

type I muscle fibers

during long duration exercise of sub-max intensity (e.g. marathon) which type of muscle fibers are primarily recruited ?

on the myosin cross bridge heads

The ATPase that is used to produce a muscle fiber twitch by way of sliding filaments is found on?

the increased number of mitochondria

the capacity of endurance training to increase the amount of ATP produced by oxidative phosphorylation is due to?

motor unit

a single motor neuron and all of the muscle fibers that it innervates is a?

type IIX to type IIA

both resistance training and endurance training result in the conversion of one muscle fiber type to another. what are the types?

alveoli

within the pulmonary system, the actual exchange of gases within the blood occurs at the?

20-25-fold

during maximal intensity exercise minute ventilation can increase by how much?

70ml

under resting conditions stroke volume in a typical male(70 kg) is about how many ml?

cardiac output

the amount of blood ejected from the heart per minute is referred to as

stroke volume

the frank starling mechanism plays a vital role in determining what?

5-to6-fold

during max intensity aerobic exercise, cardiac output increases by _______ in an untrained individual

C.increased resting cardiac output

which of the following adaptations would NOT be expected to occur as a result of long-term aerobic training.

A.decreased resting HR B.increased resting SV C.increased resting cardiac output D.increased max HR

A.↑ in end-diastolic volume

while performing a running workout of submax intensity which one of the following responses would be expected to occur.

A.↑ in end-diastolic volume B.↓ in end-diastolic volume C.↓ in ejection fraction D.↓ in cardiac output

B.lower heart rate

compaired with running, swimming will result in _______ even if exercise intensity is the same.

A.higher HR B.lower HR C.lower cardiac output D.higher cardiac output

capilaries

the exchange of gases between the blood and the surrounding tissue takes place at these vessels.

arterioles

the process of vasoconstriction and vasodialation which regulate blood flow to a given muscle mass occur at the _______

D.increased diastolic blood pressure

during aerobic exercise which of the following responses would NOT be considered normal?

A.increased systolic BP B.increased pulse pressure C.increased mean arterial pressure D.increased diastolic blood pressure

B.blood pressure elevations are highest during isometric muscular actions

which of the following reguarding BP and resistance exercise is correct?

A.people with mild CVD should not lift weights

B.BP elevations are highest during isometric muscular actions

A.men produce more testosterone than women

the reason that men have higher hematocrit and hemiglobin levels than women is

A.men produce more testosterone than women

B.men have greater muscle mass than women

C.women experience menstrual blood loss

D.men train harder than women

D.leukocytes

the cells of the blood that are often called white blood cells are the

A.platelets B.erythrocytes C.plasmacytes D.leukocytes

A.30min B.60min C.10min D.90min
