Yes, it is chronic inflammation that is harmful. I am intrigued by the question of how best to avoid chronic inflammation. Including days of complete rest in a training programme is one approach but I am not sure it is the best method. There is a close relationship between the activity of the autonomic nervous system and the immune mechanisms responsible for inflammation. In general, the parasympathetic branch of the autonomic nervous system promotes recovery. I am currently exploring optimum ways of invoking parasympathetic activity. The scientific literature does not provide a complete answer, though it is a good starting point. As I see it, we each face the challenge of interpreting our own responses to various possible strategies for balancing stress and recovery, taking account of the general principles that can be extracted from the scientific literature. I have been thinking a lot about this challenge in recent months. I am thinking about writing a few blog posts about my experiences, mainly because assembling the ideas helps me clarify my own thinking. Perhaps others might be interested, though ultimately we each face unique circumstances. |

I see that Carlton Palmer struggled in the Sheffield Half-Marathon on Sunday after suffering a small heart attack. Despite having a previous history of heart issues, he still took part and had some discomfort in the first mile, yet carried on and finished in just over two hours. For me, his maximum heart rate of 232bpm is alarming. I tend to slow down if I get into the 180s and avoid going over 185 at all costs as the recommended rate (220 minus age) is always likely to be exceeded. |

I see that Phil. He posted the Polar stats on his Twitter. His avg was 154 for the race and I could be very wrong but I wonder if that 232 is a misread. Surpised that an athlete, who has had previous heart issues would continue running for 12 miles if seeing/feeling a 232bpm reading. He has said he is being kept in with a suspected small heart attack. Doing tests. I wonder if he took himself to hospital after seeing the reading via his HRM. Could someone run a half marathon for another 12 after saying his heart 'played up' in mile 1? Seems like he will be fine from his tweets, which is great. |

232 in the first mile is obviously an issue or a misread. Presumably he felt the issue which means it was a bit mad to carry on. Surrey Phil The recommended rate (220 minus age) is always likely to be exceeded. Lots of people have max hrs above the formula. It's not a recommended rate. |

Yeah, my max HR is 20+ beats higher than the result of this formula, and I don’t believe I’m an outlier by any stretch of the imagination.

My HR is now right up the creek. Even though my heart and arteries are functioning ok I'm not able to get anywhere near what I was doing just three years ago, maybe long covid. A post above mentioned hard running/races every weekend once upon a time; days I recall indeed but also nearly all my training running was at the top end. Hard! Especially on club nights! We're talking early 1980's here. That was seemingly ok for a decade. Unfortunately there don't seem to be many useful studies concerning the decline in pace for really older (old!) folks who run! I can hardly call myself "a runner" these days, possibly a "jogger" but more obviously a "plodder". I had hoped that my decline in pace would be gradual but it came at me like a sprinter! I'm 74 and started running at age 29 and during the period had supposed that VO2 declines etc amongst the running fraternity were not as marked as in the general non-running population . I'm putting mine down then either to post covid or just bad luck. |

But Steve, you are still out running and I would put money on you being fitter than 99.999% of 70+ year olds.

Mt non scientific thinking on healthy running aligns with this TedTalk, ie if you just want health benefits from running, you shouldn't go too far, or too fast. I certainly think for me, racing a marathon tips me over from being a healthy hobby to being slightly destructive. Bit I also couldn't just run purely for health, I need the competitive side of the sport to spur me on. So I haven't run a marathon for about 7 years, but maybe will do another next year, if my old bones allow. |

I'm not sure that running too far or too fast is the key. I would say not allowing yourself sufficient recovery is probably more important - and recovery doesn't mean just rest, but active recovery, getting your parasympathetic nervous system working as quickly as you can, reducing your cortisol levels so that you're not always swimming in the stuff.

I agree with a lot of the points that O’Keefe make in that Ted talk, but I found his style of presentation too much like that of a snake oil salesman. As far as I could see, there were definite inaccuracies in the way he presented the data. I discussed O’Keefe’s talk in my Word Press blog in 2013, shortly after he delivered that talk. canute1.wordpress.com In my blog I also provided links to some critiques by other experts. Nonetheless, at that time (a decade ago), I agreed with O’Keefe’s conclusion that if your goal is to maximise the length of your life, the best strategy is probably to exercise regularly at moderate intensity. I still broadly agree with that, though I think that a modest amount of intense training is probably OK provided you ensure adequate recovery, as implied by J2R. In recent times I have been re-examining the scientific evidence, and also exploring what seems to work best for me, personally. As I mentioned in the above post (number 2653) on this thread , I am thinking about writing a few new blog posts updating my current thoughts on the issue of recovery, as soon as I can find time to do so. |
