Don't think anyone would argue that good skiing requires a certain kind of strength and balance. So just as you can try to match the strength demands of skiing by doing, say, one-legged squats, can you not also try to match the balance demands by doing the same?
If you took a trained ski racer and asked them to balance on one foot I doubt they'd have any problem doing so for an extended period of time. Your average citizen, well...
There is a very good skier named Blake Saunders who posted here for a while, and who advocated hacky sack as something that would help with mogul skiing. .... I'm not a neurophysiokinesioligist, but it seems reasonable that hacky sack might indeed match certain demands of effective mogul skiing....
Kook, are we in violent agreement, or... ??
I'd put hackey sack in the same category as slacklining -- maybe good as a way to get the nervous system firing for a warm-up, also a good way to engage in active rest and team bonding.
However, not a good way to train the strength and conditioning demands of bump skiing, and certainly not a good way to approach training the movements required for bump skiing.
S&C-wise, for bump skiing you have competition runs which are quite short and involve explosive, high frequency movements plus some gymnastics thrown in. For competitive moguls skiers, you also have long training days on-snow. For recreational bumpers, the intensity of a single run will seldom (ever?) match the intensity of competitive moguls, and likewise unless a recreational skier hits the park they are probably keeping things close to the ground for the most part. But, again both longer runs and long days. The strength and energy demands are therefore quite different from hackey sack for both sets of bumps skiers (and also rather different from ski racers, because the timing of muscle contractions is different as are the distribution and length of Gs).
Balance-wise, obviously the two activities have virtually nothing in common.
Reflex-wise, yes, both hackey sack and bump skiing involve reflexes and a sort of not-quite-conscious decision making, but both are a classic case where you can't change your raw processing speed by getting better at learned movement chains for a specific activity. For instance, a season of bump skiing won't make you dramatically better at hackey sack.
The cross training for competitive mogul skiers is very specific. For instance, learning jump involves water ramps and tramp work. Both of those have their shortcoming relative to snow, because of the slight difference for water ramps and dramatic differences on tramps from snow, but they afford lower-consequence environments and the ability to get in lots of reps while developing skills, and transfer well because they are very specific.
Likewise, for a recreational skier in particular, putting on inline skates and finding a paved pump track where available would be one ideal summer scenario for learning pumping and absorption with specific movement transfer over to bumps. Getting on a dirt pump track on a bike will still have a lot of carryover, and even more so if the recreational skier is the very rare adult bike rider who learns to manual and then manual through the tightly spaced "bumps" in those sections of a pump track where this helps.
Playing hackey sack would however be unlikely to actively HURT mogul balance. An example of something that could be a real negative would be a lot of bosu ball work, if someone does it in a way that they think mimics bump skiing. What that bosu trainer can easily do if they aren't careful is degrade their on-snow bump movement patterns while becoming a proficient bosu jumper. An analogy here would be a tennis player who starts playing a lot of racquetball and thinks it should help their tennis game.
I didn't watch the linked video but based on video of Blake's I've seen in the past he was/is a very good and athletic skier, I total agree about that.
