Measurement of Heart Rate for Autonomic Nervous System
Abstract: The Autonomic Nervous System lab was designed to measure reaction times by using a variety of tests that affect the heart rate. These tests were the startle, stroop, Valsalva maneuver, diving reflex, and a test of our choice. The test our group chose to measure the heart rate in response to doing a trust fall to anticipate the stress right before the fall. To begin this lab we chose a participant, and then hooked their finger up to the pulse transducer sensor. Using the chart 5 program on the lab computer the participant’s heart rate is measured. Before beginning each test we measured the heart rate of the participant to find the resting heart rate, which was named the “control” portion, and then the heart rate was measured once again when the actual test itself was done being the “experimental” portion to see whether the heart rate increased or decreased due to the test.
After receiving the data and applying it to the graphs, it was shown that the heart rate increased after the startle test and the stroop test. But the heart rate decreased after the diving test and Valsalva maneuver. During the diving test the heart rate decreased after due to the anticipation of placing the head into the freezing cold water. During the Valsalva maneuver the heart rate decreased because of a release in pressure throughout the body. Heart rate should be fairly constant in all humans; however the rate of speed will differ between different individuals.
Introduction:
The nervous system is defined as “a fast-acting control system that triggers muscle contraction or gland secretion” (Marieb 2010). This definition states that the nervous system is the reaction from the brain to the body in order to function in different variations. The nervous system begins in the brain and spinal cord, here three functions take place; sensory input, integration, and motor output. The nervous system is divided into separate
