I don't think it's a football. I think it's either a medicine ball that is not drawn properly looking more elongated than it really is or it's a rugby ball. Given how it's held, how it looks as if it rests on the persons forearm and how it appears to have six sewn panels I vote for a medicine ball drawn from an incorrect perspective. It would alos make sense that someone would be wearing period "work-out" attire when exercising with a medicine ball.
