No, although swimming requires a lot of energy, so does football. It's a guy thing, so football players, like linemen, eat more than Phelps.
The answer is usually 3 or 4 depending on whether the team plays a 3-4 defense (3 defensive linemen and 4 linebackers) or a 4-3 defense (4 defensive linemen and 3 linebackers). Occasionally teams will line up with 2 or 5 linemen, but this is very rare.
