NSCA-CSCS CHAPTER 6 EXAM2024/2025
A 17 year-old high school cross-country runner has been training
aerobically for six months in preparation for the upcoming season.
Which of the following adaptations will occur in the muscles during that
time? - Precise Answer ✔✔Hypertrophy of Type I fibers
The amount of blood ejected from the left ventricle during each beat is
known as what? - Precise Answer ✔✔Stroke Volume
What does not normally increase during and aerobic exercise session? -
Precise Answer ✔✔Diastolic Blood Pressure
The mean arterial pressure is defined as the - Precise Answer
✔✔Average blood pressure throughout the cardiac cycle.
Primary training adaptations of elite aerobically trained athletes include
what? - Precise Answer ✔✔Increased maximal oxygen uptake,
Decreased blood lactate concentration, and Increased running economy.
What is an early adaptation to acclimatizing to high altitude? - Precise
Answer ✔✔Increased resting cardiac output
, Cardiac Output - Precise Answer ✔✔The amount of blood pumped by
the heart in liters per minute and is determined by the quantity of blood
ejected with each beat and the heart's rate of pumping
Stroke Volume - Precise Answer ✔✔The quantity of blood ejected with
each beat.
Heart Rate - Precise Answer ✔✔The heart's rate of pumping
What is the equation for cardiac output? - Precise Answer ✔✔Q = SV x
HR
End-Diastolic Volume - Precise Answer ✔✔The volume of blood
available to be pumped by the left ventricle at the end of the filling
phase, or diastole.
Venous Return - Precise Answer ✔✔The amount of blood returning to
the heart.
Frank-Starling Mechanism - Precise Answer ✔✔With increased
volume, the myocardial fibers become more stretched than at rest,
resulting in a more forceful contraction and an increase in force of
systolic ejection and greater cardiac emptying. This is also related to the
concept that the force of contraction is a function of the length of the
fibers of the muscle wall.
