Hi Herb,
I would amend your instructors comment to, one should not stand
for long while riding - sitting IS better.
However, as Sheldon Brown's article says there are still reasons for it. I have adopted a habit on the 200K rides I do of standing for 6 to 12 strokes every time I start to lose momentum on a grade, when my cadence gets low enough that I can stand and stroke smoothly. I do this to keep my butt happy, and it works really well. I have to practice standing to have the strength to do that on such a long ride. You might see me practicing standing for that reason. Standing also shakes the cobwebs out of your back, neck, arms, etc. I also stand because it is fun. On certain roads with a long series of little short steep "rollers," it is possible to stand and "run on the pedals." This is an incredible feeling for as long as it lasts.
The situation that Sheldon did not mention is keeping warm. On that cold ride some of us did two weeks ago, I was purposely doing all sorts of unusual things in order to enjoy temperatures in the teens. Because standing IS inefficient is is a great way to get heated up in the cold. We would brake going downhill and stand going up. It is also inefficient to put 30 pounds of rocks in your pannier, but that too keeps you warm and working hard at lower speeds (less wind).
Also, the inefficiency is a good way to get more of a workout in a short amount of time. If I only have time for 20 miles, I might stand up and hammer the hills too get more out of the limited opportunity. If you only have 30 minutes to spin in class, you might want to stand to get a higher HR - not that you can't achieve the same thing sitting.
But for Umstead on a leisurely ride, I am with you instructor, using a low enough gear, being practiced enough to maintain a high smooth cadence, and sitting is the most efficient way to make good time on a hill that has a good surface. For 99.9% of road riding as well sitting is the best thing.
Anyway, for me I need to maintain the ability to stand, even if I don't do it much becasue it is inefficient.
Mike
