  • Cooling down seems to be a part of every ride or cycling workout, but is there actually a physiological reason for doing it? Is there any benefit to the cooldown? I dive into the science to get to the bottom of this question.

    The two main reasons that I like to cooldown with some zone1 spinning at the end of a ride (particularly a turbo trainer session) are simply that (1) it provides a "nice" transition from a sympathetic/"agitated" nervous state back to a parasympathetic/calm state and before diving back into my day, its the same as why a commute in the car between work and home is nice, to provide a buffer/transitional state for you to adjust from one state to another and clear your mind, and (2) when you've been exercising your body temperature remains elevated after exercise and its simply more pleasant to finish being hot and bothered on the bike (where you have fans) than off it - I still have bad memories from school gym classes where you'd finish your PE session and then have to hurry to get straight to the next class - even if you showered you would still be sweating in your school clothes in the next class, very unpleasant - much nicer to properly cool down and adjust to a "normal" state while still on the bike, *then* have your shower, after-ride snack/shake etc.

      Totally agree with XX. Like a lot of things in training, I've thought for a long time the cool down was BS, but at the same time it would be very unnatural to not make some kind of gradual transition from hard work to normal life. There's been a lot of research lately on the sympathetic/parasympathetic nervous system , so it would be interesting to see some research looking cool-down from that angle

    Correct me if I am wrong, but backwards hat Dylan speaks for all of us (!) when he points out the higher average speed without the cool down.
    I mean, if your average speed is 34,1km/h you aren't risking the 33,9 by going easy for 5 min.

  • @Bendersnatchling
    @Bendersnatchling 2 роки тому +4

    3rd comment, sorry.
    There is a huge mathematical or design problem with these studies.
    When you make such a study you usually don't present an average effect, but what's labeled in the studies as CI -> confidence Interval.
    Furthermore you are trying to find a good estimator for the true value you are looking for.
    That estimator is a point estimator, so a certain number, but but the confidence interval will be around that value and the size of that confidence interval depends on the standard deviation of the observed values and the number of participants.
    The last part before we can understand the problem:
    A study will always statistically test wether it is POSSIBLE that the observed data is merely randomly different from what you observe if there was no effect. (Read that again, it's somewhat complicated).
    In this case: Is it possible to get the data you got, if a cool down has no effect?
    If the confidence value of the estimator includes a possible effect of 0 than you can't be sure that it does have an effect.
    So, if the effect you are looking for is small and the standard deviation is high then you need a very high number of observations or otherwise the confidence interval will always include the 0.
    The p value alone is misleading here. Usually the p value for statistical significance is set to 5%. So if there is a 5% chance or higher that you would get the data you observed, if there was no effect (of cool down) then you would say: No statistical significance.
    Basically every study that includes 10 or 20 people by design can't say with certainty that a small effect does exist.

    That's super interesting.
    I remember Jan Frodeno said in an interview that he believes the Olympic race will end in a sprint so instead of a cool down he sprinted at the end of every run in preparation for that race.
    Turns out he was right and won the triathlon Olympic gold medal.🪙
    He also said he barely even stretches and as far as he knows neither do his top competitors.
    Now those interview might be 5-10 years old, but he got into Olympic gold shape that way.
    Unfortunately those interview are in German but he might have told these stories in an English interview as well...

      Yes and Michael Phelps and all the best swimmers in the world stretch and warmup their legs & shoulders before every race so ?
      Also in olympic games you don't push your body to the limit like in an iron man, did you ever saw an IM champion sprint on the finish line ? I saw no one ever.
      Jan frodeno explained greatly how olympics games are just "a start" in you career and experience and if you look closely the NOR team are doing just the same right now.
      Really depends on your effort & your goal.

    • @SimonTheWattopian
      @SimonTheWattopian 2 роки тому +1

      @R1 Shoulder flexibility and mobility are actually important determinants of performance in swimming. On the hand, natural range of motion is enough for cycling and running, thus stretching is not important and doesn't improve performance as shown by the science.
      Have you ever seen triathletes after they cross the finish line in an Olympic triathlon? They usually collapse, having pushed their body to the limit. It is a different kind of limit compared to an Ironman - limit of lactate clearance and tolerance vs. limit of glycogen storage and fat oxidation rate.
      And yes, I have seen Ironman athletes sprint to the finish. For example, Chris McCormack and Lothar Leder at Challenge Roth.

    • @user-ur5vw1gi4v
      @user-ur5vw1gi4v 2 роки тому

      @@SimonTheWattopian Agree with the range of motion and stretching.
      But so far Olympics are not about breaking records, it's about being the best which is far different and this is why Frodeno explain well how he had two careers : One before the olympic and one after he decided to stop olympics.
      -Look at Eliud Kipchoge : did he made a sprint in the last 50m of his sub 2h marathon ?
      -Recent Norwegians IM team breaking all records : do they sprint at the finish line ?
      -Even Frodeno and almost all IM champions at the finish line ? Look how much videos you want you won't find any sprint.
      Why?
      Because the race is made way before these 50m and if your body start to fail then it means your performance can be improved. If from start to finish you keep your perfect and higher pace possible without any change and keep perfect nutrition then you can't sprint in the end.
      There is a huge difference between "race to be the best" and race to "reach your max human potential" : for 1) your goal is to beat the others then yes you'll have to do whatever it takes to finish first your mentality is not about breaking records or reaching your max potential, it's all about getting the gold medal.
      In 2) you know you're among the best and you're not here to prove yourself you're here to demonstrate how far you can go in your human potential and limits. This race is a shot to reach perfection. In this case if you sprint in the end it means you already failed your goal.
      Why 1) & 2) are very different? Because Jan started at 1) then said "that's it I'm the best, then what ?"
      He decided to stay in the sport and explore his human max potential and switched to 2)
      In 1) you sprint in 2) you don't

    Thanks Dyaln,
    I had a rider ask me recently about the benefits (or not) of doing a cool down after he had to cut short an indoor session. I went looking for studies that showed impact on performance and struggled to find anything to support it one way or the other. Reduction of blood pooling was often cited as a reason for cooling down, but impact on performance was often vague to non existent. It feels like a natural process and I still prescribe it, but it's great to have you looking at these things and passing on the science. Much appreciated. Oh, and I sent him this video.

    As for that stretching study, I'm wondering:
    1) which specific stretches they did,
    2) how long did they hold each stretch,
    3) were any of the stretches dynamic,
    4) did they do any yoga poses in addition,
    5) what were the subjects' baseline musculoskeletal stiffness and flexibility levels,
    6) how old were the research subjects.
    I think the study outcome would change a whole lot depending on the above. As for me, I'm gonna keep doing 20 minutes of cycling specific stretches and yoga poses in the evenings because it's a night and day difference the next day. It's not a marginal gain, if I don't stretch I can barely move the next day. If I stretch, I can function normally. The research definitely does not match my reality here. And as far as cool down goes, I also feel better with 2-3 minutes of cooldown. Research is only as good as the subjects, inputs and specific protocols used.

    What has always worked for me is first hydrate very well and do a good warm up before your ride. Try to get the heart rate up a little and get your muscles to just start to burn and then your warm up is complete. After your workout, hydrate well and replenish your carbs and a little protein helps. Taking in some electrolytes certainly won't hurt either. Cooling down never did anything to help me and stretching hindered my performance. Hope this helps someone out. 👍

And if I do my little cool-down routine (about 5 mins) then my legs usually seem ok the next day.

(I did it once on my wife’s eBike and even that was tough.) I literally do 50mile rides to/from the local ski resort, and my final third of a mile is by far the steepest segment of the day.

Zero cooldown road rides are my norm.

    I'm 60. I've had a few (not many) atrial flutter events. I've had the checks done and I'm fine. However, it appears that these problems are correlated with middle aged (late middle aged - gulp) men who do high levels of aerobic / anaerobic exercise. I have 4 friends (USA and UK) who have similar problems all of whom I'd judge to be "fitter than me". There are procedures and drugs to minimise the problem - none of which I need (one of my pals had surgery two are on drugs). My cardiologist told me that the other animal this problem is prevalent in is racing horses. The maximal work of finishing a horse race and then immediate stop has been related to the onset of atrial flutter in both humans and horses (so she says, I don't have the papers). My own experience does relate to this, on the 3 or 4 occasions I've had this, this is been in times of low hydration AND immediate stop of exercise (sprint for the finish line). For 2 years now I've had 1k slow down of letting my heart rate recover to non-stress levels gently and I've had no problems.
    So, not directly relating to the excellent debate in the article - but for middle aged+ people, it does seem that letting heart levels gently return to normal (ish) levels is a good idea. Don't act like a race horse.

    When I was a swimmer, I absolutely had to do a cooldown swim after a race or I'd cramp up. After the 200 breaststroke, I would start curling into a cramped up ball as soon as I touched the wall. If I didn't get into the cooldown pool to swim it out, that soreness would stay with me for the rest of the day, and I wouldn't be able to race well in subsequent events.
    But for training, cooldown swims were mostly mental and a time to socialize-we even have a name for talking while using a kickboard: social kick.

    Good research as always, thanks. I normally cool down for practical reasons when outdoors like you said, getting home etc, not so much indoors though. I guess if lactate does return to normal levels faster with a cool down, maybe that is why you see track cyclists doing cool downs as they might have another event later on they have to ride in. More research needed.

    Hi Dylan!
    We have seen Team sky some sort of revolutionising post race procedure by riding on the rollers after the race and today almost everyone does it. According to your Video this would be useless... but why are they doing it? Any guesses? And another question. What about an easy ride after coming home for maybe 30 Minutes 3 hours after the race?

  • @10ktube

    Ironically, I watched this while spinning down on the trainer after a hard tempo ride. I've gotten off my cross bike, went to the awards, went to the car, drove home, and have lived to tell the tale many times. And, I've also done many times where after a race I went to the car and spun on the trainer easy and been just as fine. It's a mental break for me more than anything.

    Lactate has correlation with tiredness and soreness but that doesn’t mean there’s a cause and effect relationship. Lactate is high after anaerobic bouts. I e very hard efforts that cause fatigue and soreness. It is however good fuel and muscle tissue including cardiac muscle as well as brain will use it when intensity drops and oxygen becomes available to burn the lactate off. Going through the shower and rushing off to work will be sufficient to rid lactate. If that is your concern. Which it probably shouldn’t be.

    I was told when I was young that I should at least jog a few seconds to allow the heart rate to come down more controlled. I was surprised there was no discussion about that aspect in your video. I just now tried to find a research paper on the topic but could not. In your research for this video did you come across any studies about this? What would be your advice for someone doing very hard 30 second effort repeats? "You can come to a dead stop after" OR "try to allow the heart a few seconds to come down more controlled"
    I am very curious about this.
    Thanks for the video and sharing the research!

    @robertlee3002 2 роки тому

    Useful video, as always, and great all Dylan's content has a scientifically backed basis. I thought it would have been useful to balance out the analysis by looking at warm ups and their potential benefits, particularly given one of the points in the video was around what to do if time-strapped. Warm up is definitely key, physically and mentally, particularly ahead of a hard session. If doing a fitness test or before an event (particularly if a shorter, higher intensity event), it's important to progress body to a state for optimal performance, therefore warming up with some shorter bursts of higher intensity is key to enable vascular shunting, priming the right energy systems, increased energy metabolism, and to instigate homeostatic mechanisms (e.g. sweating). In a structured training session, the warm up is often technically focused - i.e. it will include drills (probably less obvious for cycling, but for triathletes out there, there are plenty of running and swimming specific drills that are usefully built into a warm up). Another component of a warm-up is neurological pathway recruitment - e.g. if you include specific muscle activation exercises specific to the session/sport, then you will carry this through to the session itself and ensure optimal targeting of specific muscles/muscle groups. For example, if you are over-recruiting quads vs hamstrings during running or cycling, then alongside targeted strength training exercises, specific activation exercises (using bands or body weight) can help address the imbalance (in turn improving efficiency and therefore performance, as well as reducing likelihood of injury).

    One thing you did not touch on is the elevated glucose that occurs during intense exerecise probably as a result of increased sympathetic tone.

    Cool down, especially on the trainer, just means I don't spend the first 15 minutes off the bike sweating profusely. Cooling off and getting my HR down before stepping off the bike allows my to relax more comfortably.

  • @cnay2983

    I'd imagine this topic is very relevant for those atheletes that train indoors. Since I moved back outdoors to do all my training warm ups and cool downs are just part of the 10-30mins till I get to the appropriate terrain to train! I remember hating the cool down period after an indoor session as Id just want to collapse on the floor but I like that outdoor training forces me to put in extra miles

  • @6SpeedTA95

    I’d like to see you do something on back to back riding days. For example, if someone has a long ride Saturday and maybe that’s 150tss if they go do 150+ on Sunday is that hurting their performance? Is there a point where it helps vs hurts? Maybe if Saturday is 125 tss a long jard Sunday is ok and you can rack 250 tss? Maybe the body hits a tipping point at 150tss Saturday which makes a hard ride Sunday detrimental? I have no clue what these numbers would be and probably the type of workout matters too. All z2 accumulated over 3 hours is different from gobs of intervals accumulated over 2 hours.

Another thing I noticed is the older one gets the harder it is to optimize one's body temperature. I prefer biking in temperatures anywhere from ten to sixteen degrees Celsius.

    Hi Dylan. A question about ftp. Is the 20 minute ftp test really accurate? I mean if I do a ftp test and manage to hold a pace that gives me an ftp of between 200 and 250 watts for 20 minutes (I'm less than average). That does not mean that I can hold an average of 200 watts for a 3 hour ride. Would it not be more realistic to measure ftp over a longer time to get the numbers to be more accurate?

  • @Cookefan59

    I think the best benefit from a cool down is psychological as you stated. Preventing mental burnout can be just as important as anything but not everybody needs to do it especially if you’re late for work in the morning after your trainer ride. Your run to the shower and speed dressing can be your cool down. 😂

    A cooldown goes a long way in restoring blood glucose to normal levels, which is definitely important for anyone who is diabetic, as lower level muscle contractions facilitate glucose reuptake without the use of insulin. The same reason we should all be taking a 10-20min walk after a meal. It can cut the amount of insulin we need to produce in half. Pretty interesting.

      There are a lot of things that WT teams do that are just tradition and a cooldown is certainly not hurting their riders so I don't really see a need for them to stop doing it. I think people assume that WT teams are doing everything 100% correct but we don't have to look very far back in history to know that's not true with riders using loose fitting jerseys, narrow tires, tiny cassettes, etc. I don't see any reason why they won't continue to improve their methods and they'll look back in 20 years at some of the things they do now and shake their heads.

    Cooldown for me is largely psychological, so I try to do one whenever I can. The trend to remember the beginning and end of a workout more clearly means I'll dread the next interval session less if I chill for 5-10 minutes at the end of a workout. If there's a recovery benefit, cool? If not, that's fine too.
