This year I have been fine tuning my training. Due to my schedule I can only ride 60-80 mpw. I have added weight training and it has helped me significantly, especially my legs. I have more power with less effort. My hill climbing has improved. My recovery rate has improved. I have also discovered the benefits of "push/pull". It does take some practice and I'm still getting my leg muscles conditioned to it.

The push down comes easiest and is second nature to everyone. The next part of the stroke your likely to develope is the pull back at the bottom of the pedal stroke. The last thing i developed was the push over the top of the stroke. I have read studies that have stated that no matter what you do your never going to create power in the last 90 degrees of the pedal stroke just before you get to the top. But by lifting your knees as high as they can go you'll find that you are going to naturally push over the top in the 12 o'clock position. For me this inceased by cadence by about 8 rpms and my wattage output by about 15 watts at no increase in heart rate. A free 15 watts of power at less muscle fatigue. Viola! Eric

In fact "muscle growth" (increase in muscle cross sectional area) in ECP is likely to be detrimental again, there's no evidence to support this. i know more people who are injured in the gym or cross training than from any other modality there isn't any evidence to support this notion (that pulling up increases performance). what we do know is that better cyclists either push down more or pulling up makes no difference. i think you should all shut up and listen to what ric has to say he is obviously very qualified and the best way to improve is to ride...hard.

Anyways pulling up is where you pull up on the pedal with your legs so you are making a complete circle with the pedal, you want to use both legs all the time. It might sound like it takes more work to do that but it makes it alot easier to pedal. Your pedaling will be much more efficant, you can do drills on an indoor trainer to find the dead spots in your stroke and then work to improve that. __________________ "Pain is temporary.

But when I'm in a group of riders drafting, I will use this technique to conserve energy and that is all. If I'm looking for power its at 11oclock - 5 oclock for me. sometimes seems like 10oclock being pushed up over the top and down to 5oclock. It keeps a continuous motion, by the time your right foot is down to 5 oclock your left foot is at 11oclock already pushing across. No deadspots. Each type of stroke has a time and a place for me.

What effect does the aerobar TT position have on your pedalling ?

I don't use aero bars, so I couldn't tell you from that experience. I live in the mountains of North Georgia(U.S.), so really I have no use for them, just way to dangerous. All of the riding around here has steep climbing and descending. I do, on the other hand, ride a very low stretched out position. Closest I could compare to aerobars would be using barends(MTB) while riding up long steep grades on gravel roads . I move closer to the tip of the saddle to get the most out of my power. Use arms and upper body strength to stabilize hips/torso to generate more downward force. I am always faster powering big gears compared to high rpm spinning. When I do spin high cadence, I get to the top less wore out but my time always suffers. This doesn't work for everyone, I know. I'm a fairly lightweight smaller framed cyclist(135 lbs).

When applying maximum seated power, do you use vertical pedal pressure ? If you were to use aerobars, leaving the aerodynamic factor aside, would they be more of a hindrance than a help ?

I also noticed that my foot was kind of floating in my shoe. No pressure at all on the floor of the shoe, all pressure was toward the front cramming my toes and ball of my foot. I eventually became aware of this and starting applying an across the top and then down motion. The power I gained was very noticeable. Pains I used to get like lower back and hip have gone away since using this method. I would say the aero bars would help, I use my arms to stabilize my body, when pushing hard. Gives me a platform to push off. When doing a leg press, you have the back of the seat to push off of and handles to hold and pull on. Take away the back of the seat and the handles and you're not getting much done. Your body needs a ceiling to push the power off of, or we just become weight and gravity.

Also aerobars would be more of a hindrance than a help.

On short steep roller's, when powering to keep momentum uphill, I am barely on the seat (but not standing).This is something that had started when I added the down part of the stroke. As far as the aerobars are concerned, I never used them before, so I don't know how it feels. I do, however; pull like a madman on bar ends(MTB). Not sure if it is a similar style Anquetil or not, I just know that I generate more power pedaling this way.

Indeed to optimally tune one's sequence of pushing & pulling along the full circle of a pedal stroke, it would be ideal to verify on a power meter (Watts) how different styles affect the total power that one can generate. Unfortunately bycicle power meter are very expensive (in excess of 1000 USD).
However thare is a a new cyclocomputer with road gradient indication (www.clino.it, based on a microaccelerometer), which, for about 1/10 the cost, is also capable of measuring power, albeit only on uphill stretches of road. To me this is not a serious limitation, as I am anyway able to test how much power my body can generate, and I do not really care whether I can do this only while cycling uphill ... that's sufficient to verify my training fitness and how much power I can deliver for different styles of pedalling. I am using it in combination with a conventional Heart Rate Monitor, so that I can even cross-correlate BPMs with generated Watts !
OK, that I can do this only while riding uphill might be a limitation, but at 1/10 the cost I do not mind at all, it's just a great instrument !

Some of you know me from other forums, most notably Slowtwitch. To those who do not know me I am the inventor of PowerCranks. PowerCranks are independent cranks that force the user to, at a minimum, completely unweight on the upstroke. Our data suggests that the typical user will gain 40% in power, at least for reasonable distances (40K or so), after 6 to 9 months of exclusive use (it takes quite awhile to change things). Independent studies have shown cycling efficiency improvements of 10% in only 6 weeks or 3 times a week use. So, it does seem from this data that the "circular" pedaling style can make a difference in regards to to power potential of the athlete. But, that is not what I am mostly interested in talking about here. It is clear to me that most of you don't have a clue where cycling power and forces on the pedals are coming from. Those who think style doesn't make a difference cite the Coyle study, which has many significant flaws when it comes to showing what these people purport that it shows. They say that the stronger cyclists don't pull up and that the only thing that matters is how much one pushes down. B.S. Let's look at the basics of where these forces come from. On the downstroke, there are two sources of downward pedal forces. The pushing muscles are, of course, one. But the passive weight of the thigh is another. When the thigh is lifted on the backstroke, potential energy is put into it which is recovered on the downstroke. If Coyle did not account for the mass differences of the thighs in the riders in his study (which he did not) he cannot say who is pushing harder and who is not. By the same token, as long as the backward forces on the upstroke are less than those that would come from a flacid leg (which they are in everyone) then everyone is "pulling up" on the backstroke, they just are not doing so enough to completely unweight the pedal. But, everyone is putting the same amount of potential energy into the upward moving thigh. This energy must come from muscles pulling the leg up or from forces of the downward moving leg being diverted from the wheel to push the leg up, or a combination of the two. A person with a more massive thigh must pull up "harder" to achieve the same negative force on the pedal as someone with a smaller thigh even though if one were to look just at the pedal forces one would think he was not pulling up at all or equally. While he may not be driving the bicycle directly at this point in time he does get this energy back on the downstroke (when the potential energy he puts in is recovered) so it does contribute to driving the bicycle, whether it is obvious or not. Anyhow, I thought I would try to clarify this misconception of what pushing and pulling means and how it relates to cycling efficiency. Frank Day PowerCranks

So why does it make a difference weather your upward-moving thigh is pulled up by that leg or by the downward force of the opposite leg?

I'd love to believe in your product, because a 40% gain would turn me (and many other average competive cyclists) into tour-winning shape.
