At age 52, i am not really into all the falling drills I experienced in Hapkido years ago. I can still roll and fall well, I still practice them occasionally on a mat, but I don't think it would be healthy for me to do that over and over and over for hours on end.
So if you can demonstrate that you can fall, roll, etc well enough, how necessary is it to perform a lot of falls and rolls in training, or that an a modification that is not possible in Hapkido?
That really depends on the type of hapkido, the school and the instructor — and fellow students.
Speaking only for Moo Sul Kwan hapkido:
I gather that other schools don't place as much emphasis on throwing as Moo Sul Kwan hapkido. The Musulkwan in Korea was known for its full-circle throwing and Park maintained that focus in establishing his curriculum in the U.S. On a hip throw, we don't let them slide off to the side; the person thrown is to go completely over the hip and land so their feet are straight forward in relation to the thrower. The person is being thrown perpendicularly into the mat, so there really isn't a rollout possible.
The only way to really learn to throw people well is to fit (pick them up and set them down) and throw PEOPLE. I am not aware of any training equipment that replicates the feel of throwing a live person.
It comes down to reciprocity then: I will fall for you and in exchange, you will fall for me.
It takes repetition to get first a familiarity with the correct movements and eventually a mastery of a throw is to have someone who falls well enough to endure those falls without being injured.
That means great falling technique that is trained to the point of second nature and a good mat. Our "mat" is what some describe as "floating floor" — it is firm on the surface, but the whole floor moves on force-absorbing supports.
So falling is very, very, VERY important to learning hapkido at MSK.
Falling is also important to getting a deeper understanding of the throw itself.
That said, if you have already studied hapkido for many years and are of advanced age, and you still fall well then you probably don't need to
hit the mat as often as you did coming up through the ranks, IMO.
Personally, I think some falling is good in that it keeps your insides from being as "sloshy" — our bodies are constantly remodeling either stronger or weaker. It is good for personal health and well being to be hardy, to be able to endure, rather than being fragile. Falling down happens in life. Better that the body is maintaining a certain baseline than to fall one day and be injured from having grown weaker and more fragile (other than what age does to us — but we can fend that off to some extent).
So ... hours on end? I don't think that would be necessary anymore. Even coming up through the ranks, we don't fall for HOURS on end — maybe five or 10 or 15 minutes in class for basic falling training then some additional falls while practicing technique or throwing.
For example, we may be training throws and do 9 fits and one throw. Or three fits and one throw.
Doing basic falling drills a few times per week and actually being thrown maybe five or 10 times should be enough to maintain, I would think.
But you need to listen to your body (I can only hear mine and do my best to listen closely to it).
But somebody coming up through the ranks of MSK hapkido? If they can't fall, how can they participate? How can they pass on the curriculum if they were to reach dan ranks?
In the context of Moo Sul Kwan, I don't think I can with a clean conscience advance someone if they are not learning and training the entire curriculum. If someone was to learn to throw without falling for anyone else, it would become incomplete — maybe we could come up with some "Hapkido-based Hoshin Sul" but it wouldn't be the same as training in the complete art.
By the way, Mastecole: I realize you probably know most or all of this stuff. I'm just including it for others not familiar with falling/hapkido who might read this thread.
