  1. I just recently bought a Powertap and have been playing with it. If I hold
    250 watts, my heartrate at the following times is:

    0 minutes - 60 bpm
    5 minutes - 165 bpm
    10 minutes - 170 bpm
    15 minutes - 175 bpm
    20 minutes - 180 bpm
    25 minutes - 185 bpm
    30 minutes - 190 bpm

    At the end of the 30 minutes, I didn't really have much left in the tank,
    but oddly enough the first 15 minutes of holding that wattage did not seem
    very hard. I'm wondering why my heart rate continues to go through the roof
    when holding a wattage? I was assuming that the heart rate would level off
    after about 5 minutes at a particular wattage.

    Thx, Jeff

  2. a couple things come to mind,

    either your powertap is dysfunctional because the numbers show that every 5
    minutes the HR increases 5bpm = very odd these numbers would always move in
    lockstep

    or 250watts is riding a TT and there is not much fitness so HR will increase
    over time as the heart becomes tired and less O2 efficient fuels are needed

    "crit pro", information that don't make sense, HR spiraling out of control,
    .. . . with your experience, can you provide some insight?

  3. the heart rate did not go up exactly lockstep, I was estimating the HR at
    those particular times by looking at a graph, so I think the Powertap is
    functioning fine.

    anyway, I was just wondering, like I said, I thought the HR would level off
    at a particular wattage. I'm certainly no pro, I just do riding with
    friends, club rides, and one or two races a year, and this is my second year
    biking.

    I'm just getting over a cold, so perhaps I will try this again in a week to
    see if I get the same results...

    I have noticed that on a 40-50 mile ride, if I go real hard the 1st 20-30
    minutes, I don't seem to 100% recover again for the rest of the ride,
    perhaps my endurance or fitness is just poor!?

  4. Theory #1 - You were riding above your threshold pace and were
    accumulating lactate acid over the thirty minutes resulting in the rise
    over time.

    Theory #2 - You were riding on an indoor trainer without a fan
    If you do not have a huge fan on your body temp will go up when riding
    an indoor trainer. At higher temps your heart needs to work very hard
    to cool you down and this would explain the rise over time.

    Theory #3 - You did not drink much in the 30 minutes and became dehydrated.

    For long rides you should never go hard in the first 30 minutes.

  5. thanks for the different ideas, seems #1 is the most probable...

    #2...I was riding on an indoor trainer, but I had a fan blowing on me

    #3... I didn't drink anything in those 30 minutes, I didn't think you could
    lose enough water in only 30 minutes to make a performace difference?

    Try warming up properly and do this again. The difference between your 10
    minute and 30 minute HR should not be this big at all, maybe 10 beats at the
    most. Even if you are going above your threshold. Since you didn't blow up
    you weren't going above your 30 minute Functional Threshold Power.Possibly
    above your 31 minute FTP but you don't know that until you blow up.

    PE, this is intriguing. If you don't mind, could you run down what the FTP
    is? Are you saying it's a kind of power threshold that you can do for 30
    minutes and then you have to drop off the pace?

    Intriguing is only the beginning 😉
    FTP in itself is usually measured as your Functional Threshold Power for a
    duration of 60 minutes. And yes if I can still do it after 61 minutes I
    didn't go hard enough. Almost 😉 at that level the difference would only be
    fractions of a Watt anyway.
    From this you can calculate what you can expect of yourself over different
    durations
    This gives me a number to work with when calculating my training zones. Lets
    say my FTP is 270W.
    If I want to do an endurance ride for instance I'll try to average 150-200
    W. The shorter it is, no less than 1 1/2 - 2 hours, the closer I will be to
    200W. The longer it is the closer I will be to 150W.
    If I want to do VO2max intervals I will do 3-8 minute intervals in the zone
    286 - 326 W. Shorter intervals closer to 326W and longer intervals closer to
    286W.
    To increase my FTP I do 2*20 minute intervals at or slightly above my FTP
    These are numbers that I get from my Software that I download my PM to(
    PowerMeter ). They work quite perfectly in most cases and are an immense
    help when I need to pace myself. For instance for a TT or doing intervals.
    Most of the time I forget to look at my HR, it isn't really relevant until
    maybe after I download. For instance. When I do a 60 minute TT at 270W avgP
    ( average Power) my HR can average 165 bpm one day and 175 bpm another day,
    depending on weather, hydration, how well I slept etc etc. However my Power
    is what counts.

    The mailing list I recommended above is very informative. You can also read
    some more about Training with Power at
    http://www.cyclingpeakssoftware.com/power411.html

    Try to read all articles by Andy Coggan. He is the intriguing man by all
    means and he has put a *lot* of work into making Power Based Training
    comprehensive and useful to the cyclists outside of the big trade teams.

    That's a bit odd - work on endurance, maybe? Or perhaps you're either
    getting dehydrated or started that way, or you're turning a big gear and
    running out of strength (easy to confuse with running out of power).

    It normally will, roughly - actually it will go up, then almost plateau but
    continue to rise slowly, if you aren't really well hydrated and drinking
    every so often, or if you're building up lactic acid. What's your cadence
    for this?

    I find the % method of determining zones (VO 2 max done at x% of a certain
    power number) to be inaccurate. I think it's because a person's ability in
    different zones will vary from one individual to another. I prefer to
    establish zones based on performances (previous training sessions) in each
    of those zones.

    When I was approaching my peak in early August I was doing 30 seconds on/off
    or 1 minute on intervals near 600 watts each, which is much higher than the
    tables you (Per) are referring to. Earlier in the season these same
    intervals were done closer to 450 watts. I don't think there was a
    corresponding change in my LT or FTP that would have indicated how high
    these ranges needed to be as my fitness was changing.

    What ever you're happy with...

    depending on weather, hydration, how well I slept etc etc. However my Power
    is what counts.

    The mailing list I recommended above is very informative. You can also read
    some more about Training with Power at
    http://www.cyclingpeakssoftware.com/power411.html

    Try to read all articles by Andy Coggan. He is the intriguing man by all
    means and he has put a *lot* of work into making Power Based Training
    comprehensive and useful to the cyclists outside of the big trade teams.

    OK, thanks a bunch. I'll go and look those over.

    I just recently bought a Powertap and have been playing with it. If
    I hold 250 watts, my heartrate at the following times is:

    0 minutes - 60 bpm
    5 minutes - 165 bpm
    10 minutes - 170 bpm
    15 minutes - 175 bpm
    20 minutes - 180 bpm
    25 minutes - 185 bpm
    30 minutes - 190 bpm

    At the end of the 30 minutes, I didn't really have much left in the
    tank, but oddly enough the first 15 minutes of holding that wattage
    did not seem very hard. I'm wondering why my heart rate continues to
    go through the roof when holding a wattage? I was assuming that the
    heart rate would level off after about 5 minutes at a particular
    wattage.

    Thx, Jeff

    Try warming up properly and do this again. The difference between your 10
    minute and 30 minute HR should not be this big at all, maybe 10 beats at the
    most. Even if you are going above your threshold. Since you didn't blow up
    you weren't going above your 30 minute Functional Threshold Power.Possibly
    above your 31 minute FTP but you don't know that until you blow up.

    It's totally normal for your HR to continue to go up as you ride at a constant power. Check out cyclingforum's power training section for some examples of power files with relatively constant power and look at the HR's.

    PE, this is intriguing. If you don't mind, could you run down what
    the FTP is? Are you saying it's a kind of power threshold that you
    can do for 30 minutes and then you have to drop off the pace?

    -B

    Intriguing is only the beginning 😉
    FTP in itself is usually measured as your Functional Threshold Power
    for a duration of 60 minutes. And yes if I can still do it after 61
    minutes I didn't go hard enough. Almost 😉 at that level the
    difference would only be fractions of a Watt anyway.
    From this you can calculate what you can expect of yourself over
    different durations
    This gives me a number to work with when calculating my training
    zones. Lets say my FTP is 270W.
    If I want to do an endurance ride for instance I'll try to average
    150-200 W. The shorter it is, no less than 1 1/2 - 2 hours, the
    closer I will be to 200W. The longer it is the closer I will be to
    150W.
    If I want to do VO2max intervals I will do 3-8 minute intervals in
    the zone 286 - 326 W. Shorter intervals closer to 326W and longer
    intervals closer to 286W.

    I find the % method of determining zones (VO 2 max done at x% of a
    certain power number) to be inaccurate. I think it's because a
    person's ability in different zones will vary from one individual to
    another. I prefer to establish zones based on performances (previous
    training sessions) in each of those zones.

    When I was approaching my peak in early August I was doing 30 seconds
    on/off or 1 minute on intervals near 600 watts each, which is much
    higher than the tables you (Per) are referring to. Earlier in the
    season these same intervals were done closer to 450 watts. I don't
    think there was a corresponding change in my LT or FTP that would
    have indicated how high these ranges needed to be as my fitness was
    changing.

    What ever you're happy with...

    -WG

    You haven't taken a closer look at CPS have you? When I do 30 second
    intervals I'm above 600W too. You'd be surprised at how accurate it is.
    What I described above is just a small section of it. I haven't even
    mentioned TSS scores and IF numbers yet. Which is something else that helps
    you keep track of intensity and duration over a period. All I was trying to
    do was to make Badger curious enough to go read more about it on his own 😉

    From the original description
    (http://lists.topica.com/lists/wattage/read/message.html?mid=901936066&sort=d&start=100):

    "as with all systems training exercise prescriptions should be
    individualized, in this case taking into account the power the athlete has
    generated in previous similar or identical workouts...the primary reference,
    therefore, is not to the system itself, but to the athlete's own unique (and
    current) ability."

    IOW, training is testing and testing is training.^TM

    effort, consideration must also be given to the distribution of power."

    IOW, when you're playing with work:rest ratios you have to look at not only
    the power during the 'on' phase, but also during the 'off' phase, and
    vice-versa.

    I don't see how you could know that, since you follow a different approach.

    I didn't say/mean that. It's a percentage of (what you call something
    near) LT power. The intervals you would suggest for VO2max and other
    areas of emphasis are based on a percentage of (something like) power
    at a level sustainable for 60 minutes; what others would call it CP60
    or LT power, etc. For example, do the intervals at a power level of x%
    of your threshold power. Right?

    I know. By your calculations, if the power I can sustain for 60 minutes
    is 280 watts, what should my target power level be for intervals of 30
    seconds on/off for 6 minutes total times two sets? How about 1 minute
    on and 3 minutes off for a total of 5 interval times two setss? How
    about 20 seconds on and 100 seconds off for a total of three intervals
    followed by 4 minutes rest and then two more sets of the intervals?

    FWIW, I do all of these intervals based primarily on perceived exertion
    with certain high and low limits of power output. The limits aren't
    calculated, they are based on what I've done in previous training.

    While I follow a different approach I am still aware of how _you_
    calculate the zones for these intervals. By your method of determining
    zones, in the Spring I was doing them at x% of TP and in August the %
    had gone up much more than the slight change in my TP would have
    suggested.
