So much influences heart rate that comparing what your HR is at 7mph to another runner's at the same speed is not worthwhile. It is truly an individual variable. That is why it is so important to get an assessment if you are looking to quantify an adaptation. As a quick quiz, if you were told to go out and run at your lactate threshold, what type of pace would you be running at?<BR/>A) one that is relatively an all-day pace<BR/>B) one that makes you feel your dancing on that red line and if you go even a tiny bit faster, you will crash and burn relatively quick.<BR/><BR/>Phil CuttiCatalyst Coachhttps://www.blogger.com/profile/14418446488383706336noreply@blogger.comtag:blogger.com,1999:blog-8860166.post-26589559050753489692009-02-18T20:28:00.000-08:002009-02-18T20:28:00.000-08:00Great tips and links, everyone!Michael - "Why We R...Great tips and links, everyone!<BR/><BR/>Michael - "Why We Run" is a great read! I enjoyed it.<BR/><BR/>Dave - I was quite surprised by the speeds at each heart rate as well. For what it's worth, my running economy seems to have gotten much better over the years. At the last test I did two years, my heart rate was about 15% higher at each speed. I dare say it, but I think the treadmill workouts have been helpful in focusing on running economy. I spend a lot of time in the aerobic phase locking in a heart rate and seeing how fast I can run at that rate; you end up increasing turnover, dropping your arms, working from your core...all those things we read about. But best of all you can't back off your pace or you'll fall off the treadmill. ;-) So keep at it! You'll get faster.<BR/><BR/>SDScott Dunlaphttps://www.blogger.com/profile/16096284778835123584noreply@blogger.comtag:blogger.com,1999:blog-8860166.post-28401537704805276902009-02-18T20:06:00.000-08:002009-02-18T20:06:00.000-08:00Scott,Thanks for all the detail.

My body fat is 8%.<BR/><BR/>You are far faster than I am though. At 6 MPH, my HR was 125. At 7 MPH, my HR was 144. At 8 MPH I was pushing 160. I'm envious. No amount of training would get me to the level where I could run as fast as you with such a low heart rate.Davehttps://www.blogger.com/profile/11651955086323366961noreply@blogger.comtag:blogger.com,1999:blog-8860166.post-86658116625524932682009-02-18T14:00:00.000-08:002009-02-18T14:00:00.000-08:00That was one very comprehensive test of tests done...That was one very comprehensive test of tests done, so the $200 price tag was a good one - especially with a DEXA scanner for the body fat composition!<BR/><BR/>It's good to know you've improved since your previous test too, that gives me some hope that my training after some time will improve on changing the shape of my...ahem, chassis. :-)Jonhttps://www.blogger.com/profile/13275664685558526436noreply@blogger.comtag:blogger.com,1999:blog-8860166.post-49827383694500617742009-02-17T19:26:00.000-08:002009-02-17T19:26:00.000-08:00Great post Scott.

I'm reading Bernd Heinrich "Why We Run" and his explanation of V02 max makes sense to me for the first time ever. A good read... the book and your post. Thanks also to Dusty for posting the link to HR V02 max calculator. I'll link this to my blog. Cheers.

Kinesiology/human performance/bioengineering/etc departments often need guinea pigs in the form of endurance athletes, and depending on what they are testing they usually need to get a baseline indicator of fitness (VO2max, anaerobic threshold, body fat). With the testing I did, I wasn't paid a stipend but instead I was paid with information. Point being, runners looking to get some numbers might want to ask around at local universities if they're interested in saving a buck.Bobby Gillhttps://www.blogger.com/profile/08124506401194614439noreply@blogger.comtag:blogger.com,1999:blog-8860166.post-90543272820954298252009-02-17T11:38:00.000-08:002009-02-17T11:38:00.000-08:00congratulations!
