Quoted message said:It would be helpful to know your age and weight. At 72 steps per
minute that would seem to be a good bit of vertical displacement and
most likely heel strike first. If your entire body weight comes down
on each foot strike, there's a lot of energy being wasted as you have
to get that weight's center of mass back up for the next step.

The Tinikling video is around 180 steps/ minute. You see how light
they are on their feet. They're keeping there center of gravity up so
they're only lifting their legs and not their center of mass.

I read this post, and your blog, right before my run yesterday. With
your words in mind, I practiced taking quick little baby steps for the
duration of the run. I usually take small steps anyway - I have really
short legs - in the past when I tested my cadence it ran around
166ish. This time, I managed to get it up closer to the 180 range - I
tested twice, one time came in at 175, the other time 185. I ran close
to 3 miles at 11:48 pace, which is pretty good for me, though not my
fastest.
The 185 was when I was running on a long, gradual downhill. On the
downhill, I definetly had the feeling of falling, as you describe in
your blog. The weird thing however was that my right foot still wanted
to roll and push off. So for a stretch it seemed like my right foot
was acting like a piston to my left, which wasn't rolling. This was
probably also a factor of running in the gutter of the road - the
camber. Aerobically speaking, it seemed like no trouble at all to fly
down the hill at a 185 cadence.
It was harder to maintain this on the uphill. It took a lot of focus -
I seemed to naturally want to take larger strides to maintain my pace
up the hill. When I maintained the baby steps I couldn't hold the pace
without searing my lungs. And my heels started bothering me for some
reason.
I did feel like I was going faster, even with such small steps,
particularly on the downhill - I felt like I was flying. Without
rolling and pushing off with my foot, I felt more efficient although I
am still doubtful. Seems to me that pushing off would give me more air
to cover more distance - even if stride length remains small?
A couple of times I felt like I was going to trip myself up, my steps
were that small. In fact, I almost did trip once, when a car-with-
oblivious-cell-phone-using-driver came barrelling down in my lane, and
I had to quickly jump to safety on the curb. It was hard to shift from
tiny baby steps barely off the ground, to a big jump to a high curb.
Overall, this running style felt more comfortable to my body,
particularly my hips and knees. However, late last night before bed I
had a lot of grumpiness in my calves. Not pain - more like restless
legs and healthy muscle soreness like they'd had a workout. I don't
recall the last time my calves felt like they'd been challenged like
that. Usually I feel it more in my quads and hamstrings.
Here's the thing: if I continue with this, where does the increased
speed come from? How will I get back to an 8:30 pace which I was once
capable of? If it's a factor of aerobics, does that mean that my
cadence will be higher than 180? It seems to me that the speed has to
come from increased cadence, longer stride, or more powerful push
off.... but by what you are recommending, it's all about the cadence.
So am I to assume that I would have to build up a cadence higher than
180?
I guess I still don't understand how that works.
