What Is The Most Efficient Cadence? GCN Does Science

1. epo positive? :D
2. isn't the blood lactate, heart rate and stuff kinda irrelevant compared to the average wattage he was able to hold with certain cadences?
3. Dont get it. I just saw videos about seat height where the knee is slightly bent and now the same guy who made the video in the bike has a considerable knee bending...
4. 6:36 So the more power you output the faster your cadence should be. Well leisure cyclists doing 60 rpm are spot on then! Hallelujah!
5. it would be good to see 3 cyclists doimg the same 3 tests and then compare the result as that should exclude unique abilities of individual cyclist.
6. They tell me my cadence of 50 or so is too slow but my gear is 53 11 I agree that it is too slow but if I spin such a gear I will break the speed limit of most bike paths.
7. I have cycled a lot for decades. I've raced MTB and Road. For me it's a little common sense. I try to balance my muscle fatigue and cardio so nether is over taxed but balanced. When my cadence is too high my cardio is over taxed. When too low my legs give out.
   Do your own TTs and you will find the cadence that allows you to record the fastest times. The fastest time = the most efficient cadence. Mine was around 92 when younger but is about 87 now. Each person will have variations in optimal cadence because the balance for them is a little different.
   When I see a noob riding with a 110 cadence for a moderate ride in the park, I want to say something, but don't want to be intrusive. Plus I feel they will find out for themselves that their rpms are absurdly high and will adjust later.
8. Question, what difference does proper cycling clothes make over just normal clothes(T-shirt and Shorts).
   
   Thanks
9. ive experimented with different cadences over the years and I now always spin fast. I rode for a while mashing bigger gears and I found that my average speed was no faster than when I spin, my legs would get tired quickly, id get knee pain, achilles pain and I found that my cardio was not getting a good workout. I put weight on when I mashed gears. I love the feeling of spinning fast.
10. 90, wtf as he comes flying off!!
11. So let's talk about n engine for just a minute.... When you have higher rotation, torque tends to decrease, even if power tends to increase. But when you have a perfectly tuned and engineered engine, attached to a low weight car, you don't need so much torque, in order to obtain power, as you will have a higher rotation. That is the problem in phisics. When a machine based in alternative movement is created, just like an engine, or the legs of a cyclist, is hard to obtain high torque, at high rotation. In order to achieve that, you will need huge amounts of air and fuel entering the engine and a ignition system so well tuned that can burn it efficiently at high revs. The same thing with a cyclist. Training is the answer, and training at high cadence, and at the same time, producing high torque, in order to obtain high power. That is achieved by taking nutrients (fuel) and oxygen to the muscles, have a good exhaust system (in a cycling that would be taking the waste produces from the muscles) and having a perfect tuned aerobyc and neuro firing system in order to, efficiently (other than effectively), produce power. That is the graal of cycling for me (well, i understand it, but i can not achieve it... lol... this is a rela little engine :P ). And that is not at the reach of everyone. And having a coach that understand this phisics, can be so good, or so bad. That can take you to real work tuning you up, or taking the wrong pad, with your ego on command, lead you bad. Ask Ferrari, and he understand this perfectly, and know exactly what to do with a human body, in order to "tune" it for support that effort... If you know what i mean. That was exactly what he've done with Armstrong, a guy that he choose as a lab for his experiments, weakened by a desease that he tuned to exhaustion based (in my opinion) in this principle. And achieved a nearly perfect machine. Not legal though, but nearly perfect.
12. use your cadence meter to see at what cadence you A: feel the most comfortable at and B: where you climb the fastest at yet can still accelerate at the top...... there in lies the answer ...your cadence will vary by terrain slightly but there is a reason bicycles now have 20-22 gears ..... s cadence that feels good to you can be maintained and the gears used for the increase or decrease of speed IF you know your body and your bike...then your cadence meter can show you where you live
13. They weren't cheating. How can you cheat when everyone is on Juice?
14. Would some scientifically-trained folks weigh in on this?
    "Recent studies highlight lactate as a biomarker of fatigue rather than as a direct cause. The lactate-shuttle mechanism facilitates the utilization of lactate as an energy substrate in both type I and type II skeletal muscle fibres, promoting energy sufficiency during exercise. Recent literature also supports a role for lactate in enhancing human oxidative capacity by up-regulating skeletal muscle mitochondrial biogenesis."
    
    That passage reads as if there is a training benefit to provoking the production of lactate. If true, then wouldn't it make more sense to train a lot at higher cadence, perhaps racing a somewhat lower cadence?
15. Just about to go out on a ride where 'Efficient Cadence' will be on my mind... thanks for added motivation.
16. Everyone go for 60 RPMs! Get in line with local snails!
17. I was waiting for that Vader joke all video, thanks :P
18. I seriously love you guys and these videos so much! Well done!
19. ahahahhahah, that ending!
20. duu.....rian....rider..... will go mental when he sees this!
