The majority of the rikishis seem to be deliberately fat (many looks just "overweight", just a few are those who look american style), who don't start out as fat kids and became obese adults, but gain weight consciously for the carrier just enough amount to make the job of other rikishis harder or to put momentum into their moves. They seem to be active to their 35-40 birthdays; those who remain around sumo as elders not many look fat (from among whom I've seen) so they drop their layers after retiring. These are sportsman most of whom live active lives, who trains, who are quick to move. I doubt that many has sloppy fat hearts. This would need more investigation, looking at the yokozuna list above, and calculate all, then look at other rikishis how do they fare, then compare it to Japanese life expectancy (and Mongolian and maybe to other nations).
