Harimoto is hardly an example for nearly anyone though.
His dad trains him most of the day and his training routine is like, 3 hours straight short pushes, 3 hours straight something else, etc.
It's mind numbing to most who don't have his motivation, and if it wasn't, life gets in the way. The kid is also kind of a genius when it comes to his normal schooling. One of the top in Japan in maths or something like that?
I forgot where I read it.
But yeah alplay, first you gotta learn topspin man. Since you like sharing your footage, I'd love to see that. Not to give you advice or criticism or anything like that though. I seriously just want to ENJOY watching you play with a good topspin stroke because it will make me happy seeing someone as dedicated as you getting better.
I am not sure if straight 3 hours of one shot is effective. I would rather go for 10 minute x shot, 10 minute y, 10min z, 10 min x, 10 min y, 10 min z.
I will make quotes here (from wiki and other other articles which are using informations from scientific researches):
'Although varied practice may lead to poor performance throughout the acquisition phase, it is important for the development of the schemata, which is responsible for the assembly and improved retention and transfer of motor learning'
'varied practice creates conditions that are likely to encourage elaborative rehearsal (see Craik & Tulving, 1975). Elaborative rehearsal is a means by which the learner forms multiple associations with the to-be-learned material, so that it can be recalled using a variety of cues.'
But I have to highlight that:'The source of contextual interference is not well understood. At present, it is primarily an empirical phenomenon.'
Of course there is the well-known video about blocked practice vs random practice. If you don't know it, just open a thread about training, it infected the whole forum (that's our luck) .DD
