Excellent article, Dean....something that everyone should review. You younger guys should understand that the effects are cumlative...meaning it takes years to slowly but surely erode your health (don't ask me how I know this). One cardiologist told me years ago that the worse possible thing you can do is go from being sound asleep to running at full tilt in a short expanse of time - which is exactly what we do.

Interesting read. It think the article does blur semantics slightly. It seems to mostly focus on the peak sustained HR during active fire fighting. Obviously this is going to be a very high number. This is also where being in better shape will have a more profound effect. The lines are blurred however because the article then goes on to briefly talk about how our HR spikes when the bells drop. While I agree their both areas of concern I don't think they're necessarily linked. Unless the fire is across from the firehouse you're not going to go from full resting HR to full peak in seconds. There is going to be travel time where the HR will be somewhere in between. I know for me if I'm responding from home I use the drive to the FH to collect my thoughts and "settle down". In those cases if I were to wear a HR monitor you'd see a brief spike when the pager goes off, then a drop off during the drive, then another more sustained high period once we get on scene.
I think the initial spike when the tones drop can be dampened a lot by the nature of the tone. There was a study somewhere that measured the HR of FF's when they woke up to different alerts.. Bells, Klaxons, human voices, wave noises, whatever. No surprise that the study found that the HR peak was less when less jarring noises were used.
