Of course he knew better and just likes to complain for exercise because he is getting too old to run, but for those of you who are not aware, there is one big difference between judo as it was practiced at that time - you weighed in the morning of the tournament. In mixed martial arts, in contrast, you weigh in somewhere around 30 hours before you fight.
If you don't think that matters, then you have never had to cut a lot of weight to compete. Many competitors - I'd venture to say most serious ones - get into the lowest weight division they can, which often means they don't eat sometimes two days or more before and, depending on how much weight they need to cut, might not drink anything 24 or 48 hours before they weigh in.
They might sit in the sauna for hours or run in a plastic suit for an hour, and then rest and do it again.
I've done all of it (well, not the not drinking for 48 hours part, but I've drank very little). There is a limit to how much weight you can cut before it weakens you and you can't fight worth a damn.
However, if you get to weigh in 30 hours earlier, instead of an hour before you get on the mat, it's easier. You can rehydrate. Drink water. Eat food. Digest. Rest up from the 6 miles or however many you ran that day. And being an athlete in good condition, tomorrow, you can be 12 pounds heavier (or in the men's case, 20 pounds heavier) and feel fit as a fiddle. (Where did that analogy come from? Fiddles aren't fit. They can't do anything.)
Supposedly now judo is going to go to weigh-ins the day before, evaluate it and see what difference it makes. That seems very bizarre to me because I think it would be blatantly obvious the differences it will make.
- People will make weight divisions they could not previously because they will have time to recover and so,
- People will take more extreme measures to lose the weight because 1
