During prolonged exercise or at higher rates of work increases in CO 2 production hydrogen ions (H+) and body and blood temperatures stimulate further increases in pulmonary ventilation At low work intensities the increase in ventilation is mostly the result of in- creases in tidal volume
Increases with Dynamic Exercise • As work intensity rises the proportion of CO distributed – skeletal muscle increases – viscera decreases • Exercise Hyperemia – Increased blood flow to cardiac and skeletal muscles during exercise - Laughlin Am J Physiol 1999; 277: S244 Predicted Maximum Heart Rate • Standard equation Max HR = 220
What happens to the body during exercise?
During exercise, more blood is sent to the active skeletal muscles, and, as body temperature increases, more blood is sent to the skin. This process is accomplished both by the increase in cardiac output and by the redistribution of blood flow away from areas of low demand, such as the splanch- nic organs.
How does exercise affect the cardiovascular response?
With few excep- tions, the cardiovascular response to exercise is directly proportional to the skeletal muscle oxygen demands for any given rate of work, and oxygen uptake ( VO ?. 2. ) increases linearly with increasing rates of work.
How does dynamic exercise affect blood pressure?
Blood Pressure Mean arterial blood pressure increases in response to dynamic exercise, largely owing to an increase in systolic blood pressure, because diastolic blood pres-sure remains at near-resting levels. Systolic blood pressure increases linearly with increasing rates of work, reaching peak values of between 200 and 240
What are the body's physiologic responses to episodes of aerobic and resistance exercise?
The body’s physiologic responses to episodes of aerobic and resistance exercise occur in the muscu- loskeletal, cardiovascular, respiratory, endocrine, and immune systems. These responses have been studied in controlled laboratory settings, where ex- ercise stress can be precisely regulated and physi- ologic responses carefully observed.
