I went on a 60 min run today with a heart rate monitor. My average heart rate was about 184, which is basically 90% of my max heart rate (205). My max heart rate is that high because I'm a teenager. I read that 90% of max heart rate is considered anaerobic. So was this run anaerobic? |

well, that was your average heart rate, so it probably fluctuated above and below that number. |

Was I getting any aerobic benefit from this run? |

That's slightly lower than 90% but not much, depending on what your resting HR is. I'd guess around 87%, so almost certainly anaerobic. I think the threshold varies slightly individual to individual but I think it's generally between 75-80%. My numbers are actually close to what yours probably (max around 207, resting around 50) and I go anaerobic once my rate gets to around 178-179. For aerobic workouts I try to keep my average below 165, which feels pretty slow. Also, I imagine you know this already and are just giving rough estimates but, in case not, HR % is usually the measurement between resting heart rate and max heart rate, rather than between 0 and max heart rate. 90% would likely be around 190 bpm for you. If your resting HR is 45 and your max is 205 then the difference between resting and max is 160 which is your resting rate of 45 being 0% hr, and each 16 beats over resting being 10%. |

a one hour one is almost entirely aerobic. Congrats. |

No, it's really not. Resting hr has nothing to do with what percentage of MAX HR a specific RH is. 184.5 is 90% of 205. Don't mix up Heart Rate Reserve with max hr. |

No run is "completely" anaerobic. All runs have both anaerobic and anaerobic energy contributions. |

Oops....anaerobic and AEROBIC energy contributions. |

it was at the upper limit of your AT. unless something is screwed up with your heart, here's what was going on. you were doing a faster threshold run, you were using BOTH systems, primarily aerobic though. your anaerobic system was making up for the shortcomings of your aerobic system (because you were moving quickly) you produced lactate proabably at a slightly higher rate than you were able to clear it. but still, mostly aerobic. |
| Huh? |

Dude said it was a 60' run. He'd have to buffer 100%. |

'For aerobic workouts I try to keep my average below 165, which feels pretty slow.' It feels slow because you're in poor aerobic shape. If you trained at a lower HR more often for longer, you'd run faster at 160. |
| can't be 100% anaerobic |

Correct me if I'm wrong, but isn't it impossible for a run to be completely anaerobic? Even if you are going anaerobic, you are still also producing energy aerobically, right? Your aerobic system doesn't shut down when your anaerobic system kicks in. |

Go by percentage of max hr. HR reserve is a stupid concept. |

Go by percentage of max hr. HR reserve is a stupid concept.[/quote] why is ti a stupid concept? Suppose two people have the same max HR, but one has a resting rate of 40 and the other 65. Say they both go out for an easy run at 7:30 pace. The HR of the person with the resting rate of 40 will have the lower HR than the person with the resting rate of 65. Follow that to the point of threshold, and the person with the resting rate of 40 is running faster than the person with the resting rate of 65. I just don't see how the resting HR doesn't matter when a person with a resting rate of 40 has to elevate their HR by 25 more bpm than a person with resting rate of 65. |

You're not raising it 25 more bpm, you're raising it ~8-12 bpm. It's a stupid concept because the less in-shape person has to run HARDER than the in-shape person. It's a stupid concept because the better shape you get into, the lower hr zones you run in. If I get off the couch with a max of 200 and a rhr of 60 and run at 70% hrr my hr is 158. Six months down the road with a max of 200 and a rhr of 40, 70% is now 152. It's the opposite of what it should be, especially considering AeT and AnT have likely risen to a higher percentage of max hr as well. That's why it's a stupid concept. |

There are various stresses you can induce to your system. Anaerobic stress is part of a continuum. Others are right when they say you can't have done 60 minutes completely anaerobic. Was there a large stress on your anaerobic metabolism? Yes. Was the run completely anaerobic? No. To put it in perspective, lets use Daniels' numbers. Anaerobic effort begins when you start running at velocity of VO2 Max (vVO2Max) which is about your race pace for an 11 minute race. I doubt you ran at that effort level. A 60 minute race typically constitutes the max effort one can hold for a lactate threshold effort. For most elites, that is around 87-89% max heart rate. So, you more than likely put in a 1 hour time trial effort. I am not sure what your goal with this run was, but, unless you were racing (or are in really great shape) this was probably pretty taxing on you. If it was just a "60 minute run" you more than likely went way too hard. I used to tell my guys 75% is better for what Daniels would call E days with 80% absolute max (163 in your case) being the upper limit. 90% absolute max for an hour is a "hard once a week tops" workout. Also, I found that heart rate reserve tended to make me run too fast and recover too slowly, but, I was always a larger athlete with fair to middling speed. I know some folks can do the "fast all the time" thing, but, they tend to be more the marathon types than the middle distance types. Hope some of this helps. |

uh, what? i can hold 92% max hr for an hour and i'm not close to elite. using 'most' in conjunction with hr is very, very silly. |
