I'm trying to figure out how much power each joint of the lower half of a humanoid robot would need in order to operate similarly to a human being, but I'm finding different informations based on each source and I don't know very well which one is the correct.

I found this article talking about the peak power of each joint of the lower half of a human being: Table of power and peak power of human while running

Source: Joint Torque and Mechanical Power of Lower Extremity and Its Relevance to Hamstring Strain during Sprint Running - PMC

However, I found this other article that says that a cyclist can output 1600 watts during short periods: Graph showing rpm, torque and power produced by a cyclist

Excerpt of an article about Atlas from Boston Dynamics Source: Maximal muscular power: lessons from sprint cycling

Then I went looking for the power consumed by the Atlas robot, but I could only find its battery power capacity and charge time, which is around 3700 watt-hours while being operational for 1 hour while doing walking and carrying objects.

Which one is the correct power output or peak power that a human can output so it can be used as basis for a humanoid robot?
