Question
Hello, may i get help with this physiology question?
Explain the physiological mechanisms that drive the changes in heart rate between conditions
a. Between sitting up, regular breathing and immediately after exercise.
b. Between immediately after exercise, and after 60 seconds of recording/recovery
Expert Solution
Step 1: Introduction
Physiological mechanisms that drive the changes in heart rate in various physical states is controlled jointly by sympathetic and parasympathetic outflow.
Sympathetic outflow causes increase in heart rate.
Parasympathetic outflow causes decrease in heart rate.
- The heart rate at normal physiological condition is in the range of 60-100 beats/minutes.
(Average 72 beats/minutes)
