At weight parity, I agree that a brown bear has better chances of winning a face-off between the two. However, taking that the average polar bear is larger (1160 pounds among all populations' average weights) than the average coastal Kamchatkan (800 pounds), Alaskan (850 pounds), or Kodiak brown bear (950 pounds), I would take the polar bear's chances. I bet on the polar bear with a 100-pound weight advantage among the two.

Brotherbear and Ursus at CarnivoraForums had data on both of the animals' respective strengths; the brown bear notably having greater pushing and abducting strength due to it's "shoulder hump" and elbow flexibility over the polar bear, yet the polar bear has greater pulling and adducting strength due to its larger biceps and forearms, and it's elbow muscle attachments provide a greater lever in forearm movements while the upper arm remains stationary. However, at weight parity, the brown bear is still the stronger of the two also due to its leg strength (increased back-kicking strength). Neck-wise, the polar bear has a stronger neck for pulling/tugging prey out of the water while the brown bear has a stronger neck for shaking and distilling lateral (horizontal) forces. Considering all forces applied in all vectors of direction, the brown bear is stronger and more powerful at equal weights. Reply
