Ok folks, I am doing a project to figure out power to weight ratio for runners. I need this from you: 10k PR, age, BMI, gender. Here is the calculator: https://www.google.com/search?q=bmi+calculator

Most recent 10k PR (in the past two years): 39:47
10k PR: 37:42
Age: 23
BMI: 26.3
Caveat: At the time of the PR, BMI was ~25. Also, BMI doesn't account for BF%/muscle, as I'm sure you know. Just curious why you are choosing BMI
Gender: M
How are you doing the project? And what's the question you're trying to answer? I'm curious

Here is the calculator: https://www.google.com/search?q=bmi+calculatorHow do you calculate power from this info? Wouldn't it be highly dependent on body morphology, running economy/stride and elevation profile as well?

yea it wont be perfect, but something to work with. just like stryd power meter - which doesnt take these factors into consideration either. But no one bothered doing this, it has to be done!

Hi synthetic,
Disclaimer: I am with Stryd
Stryd does account for running economy and the elevation profile. Stryd also considers important factors of body morphology such as height and weight.

I get it: BMI is a short cut that attempts to cut two independent variables down to one. But it is such a total garbage shortcut! It has been garbage since it first started becoming popular 25 years ago. The latest datapoint that it is total garbage: according to recent data, Jay Cutler (NFL "quarterback", 6'3", 266 lbs) and Donald Trump (6'3", 269 lbs) have the same BMI.

But then again some fat slobs can put down impressive run numbers.. so it's fine here.
As for stryd, it doesn't factor in morphology, such as limb length. I will be more interested in the product if it gather more data points... Arm swing, knee height , kick back height, etc

How do you account for elastic energy storage and return?

Accelerometers can't determine the source of energy causing acceleration any more than strain gages can determine the source of energy generating force (torque).

Try this experiment: Hop in place at your own self selected height and frequency. Note how hard it feels; not very hard at all.That's because when you hop at self selected frequency you take advantage of energy storage and return from your "leg spring". Just like you do when you run. Now do a hop and stop, hop again, stop, repeat several times. Note how hard it feels; much much harder than self selected hopping. When you hop and stop, each hop is done with muscular power and the metabolic cost is much higher. I would expect that anyone who wants to make an objective measure of muscular power during running should know this and make an attempt to account for it.
Re: run power project [Bio_McGeek]

Try this experiment: pedal your ergometer at, say, 200 W while seated, then while standing. Would your metabolic rate be different? Almost certainly. Would your power output be different? No.
IOW, you're thinking about the input, whereas what Stryd (or, e.g,, SRM) is measuring the output.

Let me ask a different question: How does styrde account for negative power?
