CARDIOVASCULAR ADAPTATIONS TO TRAINING

Question 1

Training intensity

Answer 1

is the most important factor in maintaining cardiovascular fitness. To determine the training intensity, it is necessary to determine the individual’s theoretical maximum heart rat

Question 2

Endurance training

Answer 2

results in an increase in cardiac dimensions, mass, and the size of the coronary vascular bed (increased capillarization).

The internal diameter of coronary arteries may also increase as a result of training.

More importantly, the arteries are more distensible during exercise as a result of training.

training results in an increase in blood volume

Question 3

Stroke volume

Answer 3

greater at rest, at submaximal exercise (absolute and relative workloads), and at maximal exercise following an endurance training program

Question 4

Resting heart rate

Answer 4

is lower following endurance training. The heart rate response to an absolute submaximal amount of work is significantly reduced following endurance training

Question 5

Maximum heart rate

Answer 5

unchanged or slightly decreased (2-3 bpm) with endurance training.

Question 6

Resting cardiac output

Answer 6

is not changed following a training program, however, it is achieved by a larger stroke volume and a lower heart rate

Question 7

VO2 max

Answer 7

increases as a result of endurance training; improvements of 15% are routinely reported with training programs that meet the recommendations set forth by the ACSM
