You're putting out great content, but I find the teasers on these excerpts to be frequently misleading and it's starting to get annoying. What's the overlooked training metric we were promised? It's totally unclear from this video. Getting a little too cute and click-bait-ish in your titles may drive more traffic in the short term, but folks such as myself that have devoted 7 or 8 minutes to learning something new only to be disappointed a few times are going to stop clicking in the future.
Agreed, totally unnecessary as the actual video is better than the title
The value they’re speaking of is calories.
If I were interviewed by him I would be upset by being misrepresented in his misleading, sensationalist, and clickbait titles, especially if I was giving a nuanced and balanced response to something I had thought about a lot. Poor journalistic ethics.
Exactly - good content, but stop the clickbait please. This ain't got what you said it got.
How did you get “stop using average power” from that snipped. Hes talking about not using normalised VO2 max and not reducing weight to try to increase normalised VO2 max.
indeed
I didn't really understand how his answer addressed the question here at first but now I've listened to the rest of the episode I totally get it. I think the rest of the answer is needed to understand his point properly but if you've put the edit there deliberately to feed people to give everything a proper listen chapeau, you nailed it
Where is the rest, the short version conveys little other then training being the stimulus?
I understood almost none of this
Why is there a shift from using CTL towards tracking kJ?
Chronic Training Load is a metric used to quantify how much training was done recently. It’s based off the Training Stress Score of individual activities, and TSS is relative to FTP. 100 TSS is equivalent to 1 hour at FTP. So in the end it’s about how much time was spent at a certain power level. TSS has many downsides, e.g. it underestimates the training effect of long but low intensity activities or short but high intensity intervals, so switching to another metric could bring advantages.
Olav first connects CTL with kJ/calories:
Ultimately, endurance athletes need to cover a long distance to progress in training. To go the distance, they must apply power to the pedals. In order to do that over a long time, they need to stay in energy balance at least, or better have a surplus to support muscle repair/growth.
Distance
Reducing weight to increase W/kg leads to down spiral. 5sec vs 10 min talk, same said.
Physics 101: the kJ (or kNm) is a unit of energy. Energy is power (Energy per unit time) integrated over time.
Cyclists with power meters have the ability to measure energy by recording their power vs time and then integrating it. This, energy, is the metric for a training session's load, to determine whether we overloaded and how much. One can of course weigh oneself and then compute energy per kg or whatever weight unit. What Olav was talking about, I'm not quite sure.
kJ really isn’t a good metric for training load. If you burn 1000kJ in a sprint-based workout, it will have a very different effect on your body than 1000kJ of endurance.
@@kidsafeits called intensity mate.
@@jacklauren9359 And intensity by itself does not measure training load. A time component is required.
@@kidsafe A sprint-based workout that would burn as many kJ as an aerobic workout would probably destroy you. Doing sprints is anaerobic and your anaerobic power system can only run for a minute or so at best...How many full anaerobic efforts with rests between could one do in a realistic session? The kinds of sessions that most cyclists do are virtually 100% aerobic, and so the energy metric is perfectly applicable for training load. Anaerobic work is a very small part, if at all, for most cyclists' training, for those who are doing track events like the 1k, and is also subject to making sure one does not overload excessively or under-recover. Added note: I think the ideal when using the energy metric is to divide it into two components: fat burn and glycogen burn, based on the relative percentages that are a function of intensity (e.g. Z2 is about 80% fat burn, 20% glycogen, Z4 about 50-50), so that you then have a training load calculated for both. For the anaerobic work you could do a similar thing, calculate the anaerobic load using power data integrated over time in anaerobic mode.
@@Avianthro Sprint is maybe a bad comparison. But when I do a 1hr Z2 ride and some 4x8min VO2max intervals I burn pretty exactly the same kJ. Still the physiological effect is vastly different.
Measuring something is easy, interpret the result and make proper training prescription out of it is an entirely different animal.
BTW: 80% fat in z2 is very rare (keto diet), 50% is more realistic.
Also anaerobic energy is dominant above vo2max. At threshold there is still ~95% aerobic energy.
What I got from the video is that we shouldn't be overly concerned by the optics of the w/kg metric as it can be misleading. How? You can improve W/kg ratio either by increasing your watts or by dropping weight. And where dropping weight might help increase w/kg metric, it is counterproductive as it also leads to diminished (dramatically) Vo2 max. I.e. if you don't eat properly, your overall performance will decrease (Vo2), even though your w/kg metric might look better. Hence his point of not focusing too much on w/kg by dropping weight, but instead (I assume) by increasing your watt output.
It's like personal finance - you want to make sure you accumulate your capital not just by saving as much money as possible, but by actually being able to earn more money. That's how I read it at least.
Hi really liked Olav Bu when I learned about him and his methods, but the more I listen to him I feel like he is increasingly rambling about random corellations of training metrics without really making a whole lot of sense and I get the feeling this is on purpose, classic snake oil.
Really unclear.
need a better producer
Olav Bu is the best snake oil seller i have seen in triathlon
His snake oil seems to be working pretty well
Is not the oil he sells that is working :) is the other stuff :)
@@tiagomendes6475exactly. These fackers think they are slick. They are using dr ferari’s secret that is undetectable 🤷🏻♂️
First! 😃🎉
