Buckeye - you should do it before the race so you can use the HR numbers IN the race. Just schedule them in there this week with a few easy days in between each.

This is a pet peeve of mine, too. So many people take 220-age as gospel.

I think it is important to understand why 220-age does not work:

- 220-age for maximum heart rate (MaxHR) has been demonstrated in numerous studies as the MEAN MaxHR in a normal distribution of MaxHRs
- the standard deviation is approximately 10 beats per minute
- that means that while the mean (median and mode) MaxHR for a 30 year old the is 190, 68% of the population of 30 year olds fall into 180-200, 13.5% are 170-180, 13.5% are 200-210, 2.5% are under 170 and 2.5% are over 210!
- all atheletes would agree that even the 1 standard deviation range (180-200) is far to wide to be useful, much less when you consider the tails

Finally, I suspect, although have never seen a study, that athletes lose MaxHR at a slower rate than the average of 1 beat per year. Therefore, as an athlete ages they drift to the higher end of the range.

Holy cow.

I avoided reading this thread since last year because it is just so long... but I finally hunkered down this morning with a big cup 'o coffee and I'm so glad I did. Mike, your advice is fabulous, and I now realize where I have gone wrong.

I started running for the first time since I was a kid in March 2005. I started off at about an 8:30 km pace (approx 13:40 mile), and each step was a struggle (and plagued with injury). Today, I am a little faster - around a 6:50 km (11:00 mile) pace - and while I am now free of injury (and about 30 extra pounds), it really doesn't feel as though it is getting easier. I still sweat my tookus off and each run feels akin to drudgery... and I have stayed at the same pace for the last 4 months. Sigh.

BUT! I now understand why my run times haven't improved: I've been consistently training in Z4 and never anything less! (According to your excel spreadsheet and my LT of 178, that is). So, now I'm heading out for a nice.. SLOW.. run in the rain. I've never been this excited to pound the pavement! Just wanted to stop by and say thanks for the conversation. I'm sure it'll help get me where I want to go!

Another triathlete has seen the light!

Give the HR training a chance and I think you'll be happy you did.  Your previous training gave you a fairly immediate improvement in pace but seriously limited your potential because you weren't developing your aerobic base.  Start going long and easy and before you know it you'll be running faster at the same intensity or holding pace at a lower intensity.  And probably best of all, you won't feel exhausted all the time from the hard running day in and day out.

Subject: RE: HR Zones: 220-Age - the TRUTH!

OKay Mike, I have read this entire thread in bits and peices but I have a few questions.  I plan to buy a HRM in the next few weeks that has a lap feature but right now I have the FS1 from Polar that doesn't have that wonderful function.  I have been a lacrosse player all through high school and two years of college.  I would go out and try to run 2 mile as fast as I could every time without a HRM. 

  Now I have given up on lacrosse and chosen a life style that will benefit me more then the bruises from lacrosse.  So I recently (mid April) did my first sprint tri, and got killed when I got off the bike.  My legs were dead.  I have tried working out with more bricks, and have another sprint tri in Mid june.  So now I would like to start "training correctly" and begin using the zones.  My question is how specifically again to test for the run and bike.  In the area I live (central Maryland) there are many hills and stop signs that would make the bike ride difficult.  But what type of work effort should I give on the run?  I think back in my lax days the coach had us to a EKG test and I maxed out with a max HR of like 205 or something.  I had the treadmill spinning at like 10mph.. and a 6% grade or something it was rough!  So how should I try this again. 

 

Hope this post has some questions in it and you could answer them.  Thanks again

Try using a trainer for the bike test and a track for the run. The test is detailed here. Pretty much an all out effort for the 30'.

I just got a Polar RS100 and plan on doing my LT test within the week. When setting up my watch after the test, should I be entering my LT where it asks for max HR? Is this the best way to calibrate the watch as to ensure the zones are based on my LT number and not my max HR?

How does everyone else do it?

No, subbing LT for MHR won't work...the zones would be all wonky.

My HRM lets me put upper and lower limits for each zone...does yours let you do that?

Yes, I can manually set my limits. I believe the RS100 only has 1 zone though, so I think I'd have to manually change the limits before each workout if I were to change my target.

If I can manually set my max as my LT and then manually set my high and low limits, wouldn't that work?

I don't bother setting zones in my HRM.  You really only need to remember a few numbers...Z1/Z2 boundary and Z2/Z3 boundary will take care of the majority of your training.  For Tempo sessions you need to remember your Z4/Z5a boundary.

Thats what I was looking for. Thanks!

By the way, I did a LT test on a indoor trainer last night and averaged 147 for the last 20 minutes. I was pretty burnt at the end, but not about to drop dead. Its a fine line between what is perceived as maximal effort versus what actually is maximal effort. Should I add a few beats to this just to factor in the idea of maybe falling a little short of giving maximal effort?

No.  You can always retest in a few weeks and see if you generate a better, more consistent effort.  But the test actually assumes you can't push yourself to a maximal effort (i.e., that it's not a 30min. race).  To get LT under race conditions, you'd likely have to do about a 1hr effort (think 40k TT on the bike or 15k run).  On a 30min race, you'd actually take beats off to estimate LT.

How would I know if my second effort is better, is a rise in avg. rate or a lower avg. an indicator if at all?

The LT is just a number.  One is not better/worse than another.  If you're faster, it's better.

What's a decent measure to base how hard you're really working during the TT? My cadence was always around 115 to 120. Should it have been higher, or is that impossible to answer for any single individual?

Cadence has nothing to do with intensity of effort. The measure you use is that you should be totally spent at the end of the TT.

When on a trainer, do you set the level to 0, 1, 2, ??? Whatever level you can push your hardest for 30 minutes basically?

The gear, trainer resistance, and cadence isn't really important.  All you need to focus on is that you are pushing as hard as you possibly can sustain for 30min.  Ideally you'd like to maintain a steady cadence and run the same gear from start to finish.  If you need to shift to an easier gear or can't sustain the cadence then you know that you went out too hard.  It's better to get near the end and pick it up slightly to completely tap yourself out than to punk out at the end because of poor pacing early on.  When you finish you should be totally spent.  if you re-test in a few weeks and get a different number it isn't necessarily better or worse, although it might be more accurate or closer to the real value.  Remember, we are only estimating LT here.  If you don't typically ride time trials then chances are that you didn't pace yourself optimally on the first run through the test.  That's something that will improve with experience.

I found this thread becuase I need to do some max HR testing.  I haven't had time to read through the entire thread so I apologize if I'm being redundant.  I have a few questions regarding the run test.

Does it matter if I do the run test outside or on a treadmill?  If it's outside shoud the terrain be relatively flat?

When doing these tests is it necessary to be well rested??

Quick!  Edit your post before Mike sees it!

Test can be done outside or on a treadmill/trainer, but it's more effective to do them in conditions similar to how you are training (so if you run outside usually, test outside).  

A flat course is generally better as it will be easier to meter your effort.

You should be well-rested to get a more accurate test.
