Question

Chapter 12: Cardiovascular Responses to Exercise Exercise 1 True-False. Indicate whether each of the following statements is true or false by cireling + if true and O if false. If the statement is false correct it in the space provided. O 1. The plateau seen in the exercise response of many cardiovascular variables + indicates that a steady state has been achieved + 2. Cardiac output increases during short-term, light to moderate submaximal aerobic exercise due to an increase in heart rate and an increase in stroke volume. 3. Total peripheral resistance increases during short-term, light to moderate submaximal aerobic exercise due to vasodilation in the active muscles. +O Blood volume decreases during dynamic aerobic exercise, reflecting fluid loss from sweating whether the activity lasts 5 min or 5 hr. + 0 4.

Explanation / Answer

1. The plateau seen in the exercise response of many cardiovascular variables indicates that a steady state has been achieved. True

The plateau in the exercise response  indicates that a steady state has been achieved

2. Cardiac output increases during short-term, light to moderate submaximal aerobic exercise due to an increase in heart rate and an increase in stroke volume. True

Increase in heart rate and an increase in stroke volume is seen in  light to moderate submaximal aerobic exercise which causes increase in cardiac output

3. Total peripheral resistance increases during short-term, light to moderate submaximal aerobic exercise due to vasodilation in the active muscles. False

It causes vasoconstriction

4. Blood volume decreases during dynamic aerobic exercise, reflecting fluid loss from sweating whether the activity lasts 5 min or 5 hr. False

Tere will be no much sweating in dynamic aerobics

As per chegg rules only first four subparts of a question should be answered
