Excellent analysis of power applied to pedal stroke

+1 finally someone not saying pull up on the up stroke but to un weight your foot as actually pulling up is just a waste in all but sprints

Does anyone else pay attention to the vectors? The pioneer power meter is one of the best training aids, but so few people know how to use it or even what the vectors mean. If the vector is at 90 degrees from the crank and in the direction that the crank is traveling, it is efficient. Efficiency can be expressed as SIN(offset angle). Now go back and look at the video, notice the the vectors are almost all straight down, from 1:00 all the way past 6:00. Past 45 degrees the efficiency is dropping off rapidly. The data from most riders looks this way because people learn how to walk long before they learn how to pedal. What you're looking at is another skill set poorly adapted to pedaling. If they were intelligent, they would look at which large muscle groups can produce power and where in the pedal stroke they can be effective. You have two large muscle groups, glutes and quads - they fight gravity all day. quads extend the lower leg from the knee, they can only produce forward vectors. Glutes extend the femur down from the hip, they can only produce downward force. The key to a better pedal stroke is to learn how to produce force in the right direction at the right time with the right muscles. Yes, it means learning motor skills - I'm pretty sure humans are capable of doing that...

Could not agree with you more. Another theory which matches yours, I often find myself pushing slightly forward to engage my butt muscle when climbing. When sprinting, the video is more or less spot one but you nailed it. The power should be applied and used using the correct muscle group depending on the type of effort. Only way to train those muscle when needed.

A great way to practice this is when you ride your city-bike without clips. Your push-leg does the job and then lift your other leg that it is barely touching the pedal. Next, try to feel how you your push-leg goes beyond the dead point at the bottom and then lift it instead of resting on your pedal. Next, use your forefoot and don't get your heels down at lower position, but keep it at about 10 degrees. Otherwise you will not use your calf muscle.

You don't pull, if you do that, your HR spikes for the same power output. You can only help a tiny bit to lift. Our body is not designed to pull legs up, not for hours at a time.

Beware some people have different sized legs so this affects the pedal movement if they do not wear a small lift to match the leg sizes. Spinning vs grinding is critical as you can rebuild your energy while spinning but not when grinding.

Human legs aren't built to do "pulling" work, pull is not efficient as push, we aren't machine that able to constantly split perfect between push/pull workload in circle motion, no one can do that. This is why I train pedaling on pushing as our legs were naturally built for this purpose, learn to do pushing people....
@j1y0ni8 жыл бұрын
Totally agree. As do the British cycling team as well as Dr Aurial Forrester (Inventor of SRM) Plus if you concentrate on pulling up on the upstroke on one leg with the other leg on the downstroke the leg on downstroke won't get an efficient power phase. As well as not having physically attributes to pull, humans don't have the cognitive attributes to think quick enough.

Thank you.................. I've been saying this for years, decades and especially over the past ignorant knees WAY too forward to spindle past ten years or so..........., no one believes this - in addition to being on too small a frame, but I digress............. They believe that one can pull up equal to pushing down............ Insane. Push people, push.

Actually the legs is made to pull. When you run you lift your legs and it goes down by gravity. The bike require the gravity to be use. It's not that much about pushing but more about the weight being transfer from on side to another. At the moment the legs is being contract to support the weight. All of those are made naturally, what we need to focus on is a movement circling with the less efforts and not losing the momentum of the down and up position.

When you push down the right leg your force need to over come the weight of your left leg so the best way is pull your left leg up slightly, trust me.

+Jan Kowalski at 90rpm and at optimum rpm even if humans had the physiology we don't have the psychology to process commands to the specific muscles if we concentrate on riding circles this then impedes on the power phase of the downstroke.
@johnberg1818 жыл бұрын
+Jan Kowalski you fell into the myth of the scrape pull and push mentality. all the evidence or the preponderance of the data proves that most if not all power comes from the pushing cycle of the pedal stroke. all power comes from your quads not the hamstrings. and you might beat me up the mountains not because of pedal technique but most likel because you are a skinny bike pro.
@JanKowalski-pe9lo8 жыл бұрын
I not saying that most power dont come from quads. I think that you right but... Smooth stroke is not possible to achieve only focusing on pushing and im sure you wont deny profits of smooth pedalling. In reality of pro peloton if there is any chance to turn on more muscles in the same job its worth a try as it means energy saving no questions. Even if this is miniscule.
@johnberg1818 жыл бұрын
+Jan Kowalski the key is to activate more muscle fiber responsible for the main part of the pedal stroke. this can be done or trained only with hill work, power sprints and big gear training. i agree it is not the smoothest stroke but perhaps the most efficient.

I am not a pro. I am an old phart who rides hills every day. I sometimes pull when climbing rather than down shifting, just a little bit of extra power. Also, I have some bad joints and a nerve damaged leg that limits what I can do through that leg. Pulling with one leg is a way for me to even out my effort. I could keep going in my comment. Your video is myopic. I came here to learn something, and learned nothing. Good luck to all you pros, especially when you get old.

If you peddle like a pro, and put that kind of stress on your knees, you better make sure that your crank arms are perfectly straight and HAVE NEVER BEEN CRASHED, even if they look undamaged, after a crash they can be bent and you may not realize it, and if you push as hard and fast as you can on an out of line crankarm it can destroy your kneecap, and like me, you will not be able to ride for a year.

YUKI INU 80% of the time I train on a 14 kg road bike and spinning is the key to not have knee problems. I train on the heavier bike so that when I race others on a 7 kg bike the built up muscle stamina can be applied on counter attacks and Peleton break attacks. I know some pro riders train on a much heavier bike for mountain stages so their legs are trained to that weight. This gives them massive advantage when riding their 6.8 kg bikes. Even at 14 kg to me it feels light enough and the key is to be in gearing where the priority is head wind speed . ABS = Always Be Spinning not grinding.

How do you know how long he was maintaining that effort for? Your heart rate takes some time to catch up with your effort (hence why it's not a good pacing tool). If the most powerful sprinter launches a 900 watt sprint from a leisurely pace, he's heart rate is not gonna be through the roof in 10 seconds.

Hilarious all this nonsense relying on the fact that those bikes are 6.7 kg . Lets see the numbers on a 15 kg ( 30 lbs) and how all the data goes into the trash as you now needs a sprinter type cyclist to ride that 15 kg bike. I don't give a shit how fit you are or how pro you are, Bike Weight is critical since all your training is based off that 6.7 kg UCI weight for competitions. If UCI decided tomorrow to make 15 kg bikes as standard all the top "Pros" would retire the next day. You have 6.7 kg bikes which even a child can lift and still they require drug or hidden motor assistance . Clean up the sport 30 lbs mandatory bikes and all these chicken leg Pros either put on more weight or they leave.
