Hi Guys: There seems to be lots of interest in various shapes of chainrings these days. We just published this paper showing that they have absolutely no physiological effect. Importantly, we also show that they inflate the power values provided by power meters which may explain why some...

The counterweight reduces the effort required to lift the leg. Cyclists do pull up a little bit with the counterweight just like most people do when pedaling normally with both legs. So the latter of your two scenarios.

Not that this will sway any of the true believers but we think this is the final nail in the coffin of pedaling technique lore: https://journals.physiology.org/doi/abs/10.1152/japplphysiol.00661.2020 The amazingly cool thing is that this amputee cyclist's metabolic cost decreased with the...

I would like to thank the developers for the Ignore feature. My Ignore list includes Jimmy Bee, Frontdoor, and Backdoor. Such a nicer forum now.

That would require a muscular force. Everyone does this to some extent. As mentioned months or years ago in this thread, all studies which investigate really pulling up show that it REDUCES efficiency / INCREASES metabolic cost. Even in a single legged cyclist, pulling up LESS is more efficient...

Pedal forces result from a combination of muscular forces and gravity and inertia forces. Most of the ineffective forces are due to gravity (eg the weight of the limb when the pedal is coming up). Those forces stay constant. The muscular forces that cyclists choose to produce are highly...

Simple. Because most of the ineffective forces come from the mass of the limbs (weight and acceleration) whereas the effective forces come from muscular effort. Those mass-dependent forces remain constant. So as power goes up the mass depended forces represent a smaller contribution to overall...

Re: Re: I love that you come up with all this complicated nonsensical claptrap but when given a solid research paper you respond with "Thanks for the paper, it was too complicated for me to fully understand. " With your passion for science denial and complex nonsense, perhaps you could get rich...

Re: Re: Got to hand it to you Noel, you never give up. This one seemed really promising for your side and perplexing to me initially. I know Dr. Ettema and he's a solid scientist who trained under Sjøgaard. The issue with this study finally came to me when I was reading the discussion and he...

Re: Re: Alternatively, if you would read the paper you would understand that the muscles are already doing everything that can be done to produce power. Where shall I send it so you can read rather than speculate? Of course, if your real purpose is to troll rather than to learn or even debate...

Re: Re: Its all laid out clearly in the paper, which you have not requested. Happy to send it to you so you can read it for yourself. What is your email address? Cheers, Jim

Re: Re: Okay, I think I see what you're getting at: Different techniques might produce different kineamtics which would change muscle length trajectories thereby facilitating a different approach to power production. Is that it? While the theory is plausible, the actual possible changes are...

Goodness gracious I have really missed an erudite discussion! Why didn't anyone tell me? I can't post the pdf of our recent paper because of copyright issues but I can send it to one person at a time. Send me your email address and I'll send you the reprint. It will be really good to hear about...

Re: Re: This reminded me of one of my favorite quotes from Lonesome Dove: Never try to teach a pig to sing; it wastes your time and annoys the pig.

Re: Re: Tom Petty said it best: You believe what you want to believe. Keep on peddling your pedaling Noel. Cheers, Jim
