Question:

Is it harmful to exercise above maximum heart rate during a 4-5 minute sprint?

My MHR is 162, and during sprint it gets to 175 during the last minute or 2.

Although it is relatively uncommon for a person to be able to achieve a heart rate significantly above 220 minus their age at any level of exercise, a few percent of people have genetically different max heart rates. Most of the time, this does not represent a disease state & short sprints achieving whatever max heart rate are reasonable as part of a supervised training regimen. However, it is important to be evaluated to exclude exercise induced arrhythmia. It is possible to have a dangerous rhythm that only shows up at peak exercise.
