I recently bought a heart rate monitor for running and have noticed an oddity in my heart rate when picking up intensity on a long distance run, 5km and up.
Say I run a 1:38 for first few laps, then I cut it down to 1:33 for the next subsequent laps. What I notice is that my heart overreacts at first and then stabilizes. It jumps from 158 to about 168 and then comes down to 162. Then say a mile later I increase it to 1:29 laps, my heart rate will spike to like 175 and then stabilize to around 169. Is it normal for the body to react this way to a gradual increase in resistance? What is physiologically going on that is causing this to happen?
