Ironically I would assume sumo wrestlers would be the worst at walking against a wind.
Sounds like a myth for the Mythbusters to test.
I think that would largely depend on the ratio of surface area / mass. Going by the equation:
Force = mass * acceleration
If force is constant, increasing the mass, as in sumo wrestlers who have a large mass, will experience a lower acceleration. So the wind should have less of an effect on sumo wrestler.
There is more to it, though. Since sumo wrestlers generally have a larger mass, they usually also have a larger surface area. If surface area increases, the force applied will increase since the force is the integration or addition of all the tiny little pieces of wind force hitting every part of the body. So in reality
, a sumo wrestler experiences both an increase in mass and
force in the above equation.
However, I believe the change in mass is more significant than the change in force, and since the change in mass trumps the change in force, acceleration has to decrease to keep the equivalence true, hence why sumo wrestlers should be better against the wind.
To exemplify this, someone way gain 25% more weight but their frontal surface area may only increase by about 10% since it really depends on how that additional mass is distributed about the body, and you have to take into account the three-dimensional aspects of the various parts of the human body.
