It was truly a mind-blowing experience. It | made me realize though that we're really at the tip of the | iceberg in terms of what kinds of things we could do with VR. | Up until now, the games we could play had the limit of only | taking a few key presses and mouse motion as input. Suddenly | we're now afforded the entire realm of physical motion. Not to | hype it up too much, but the possibilities feel practically | endless. | Johnjonjoan wrote: | I'd be inclined to think beatsabre is repetitive.

Which makes me wonder... Is | dance superior to repetitive exercise for seasoned dancers, | or are they actually the same thing? | gnramires wrote: | There are many kinds of dance and styles. I guess the | main ways to divide could be a) Partner dance b) Group | dance, and a') Choreography b') Improvisation. | | Even for seasoned dancers there is a lot to offer in all | of those. In partner dance you have to watch and adapt to | your partner all the time (no matter the skill level). In | choreography you of course have to learn new programs and | execute them well (displaying the desired artistic | expression), in improvisation you have to come up with | things on the fly. | | Unless you get stuck in an old routine (same old | choreography, not doing anything new, etc.), there is | almost endless variation and learning of new tricks and | nuances. | Johnjonjoan wrote: | Thanks for the info. In that case I guess we can only | infer that dance is better than repetitive exercise | providing you are not banging out the same routines over | and over. (In which case it is arguably repetitive | exercise itself) | | This aligns much better with my view that creating and | accessing relatively new/rarely used pathways is the | mechanism that keeps our brains agile. | joshuamorton wrote: | You missed solo dance as c).

The way I'm interpreting | it, I read it as you need to combine physical activity with | sensory and cognitive tasks. Which dance provides.

Take | climbing: slowly reaching for a difficult hold you've never | touched before, where you carefully lay your fingers on it, | just touching it at first to make sure it'll actually hold | you - and if not a fall an injury is certainly in there - | while the rest of your body is at one wth the rock. That's | basically the same for me. Or take snowboarding, just surfing | a gentle slope, all alone while a snow shower slowly becomes | heavier. There's no real goal there, focus fades, it's just | you going with the flow. And getting that trance-like feeling | really only works if you let go of certain natural fears. | screye wrote: | A well executed boulder can often seem indistinguishable | from dance. So many sports have a natural flow and tempo | (the zone), that once you tap into, you really do feel one | with the sport. | | Sadly, the feeling can be fickle mistress and hard to tap | into. | screye wrote: | Yeah, I wonder if they compared dancing to highly dynamic (non | repetitive) sports, then would the results be different. | | Soccer for instance, demands continuous concentration and is as | taxing mentally as it is physically, esp. in certain positions. | This seems to be similarly true with sports like hockey, | basketball, tennis, etc. Not sure how much of it applies to | stop-start sports like baseball, cricket and american football. | | Climbing requires deliberate control over muscles, breathing, | coordination and concentration, in manner that I haven't seen | in any physical activity. | | That being said, looking at some of the dancers I know, dancing | can be incredibly physically taxing on its own. | d_silin wrote: | I love indoor climbing, really makes physical exercize the | opposite of boring. | lowestprimate wrote: | Same here.

Before everything shut down I used to | practice yoga at a school here in Brooklyn that was very | physically demanding and attracted a lot of more advanced | practitioners. Most of the advanced students had long | histories with dance or martial arts (or both). All of these | arts teach increased awareness both physically and mentally, | challenges your proprioception, and surprises the body with | creative movement. | | I personally had been looking for a place to practice a | martial art to add to my yoga practice, but then covid hit | and the city shut down. Hopefully after all this is over | though. | codr7 wrote: | I'm far from objective, having practiced and taught Wing | Chun for more than 25 years; but from the martial arts I've | been in contact with, WC excels at teaching physical and | emotional awareness. | | Cuts both ways, I've been looking for oppurtunities to | teach but people are so nervous and spinning now that it's | mostly impossible to reach through. | mtalantikite wrote: | Well if you know anyone in New York I'd be happy to take | a recommendation for a WC teacher.

Internal is the sort | that says: does this study actually test what it claims to? If a | study looks in a black box, sees there's no elephant inside, and | says "there's no elephant in there! Huzzah, we've proven it's a | tiger!", that's an internally invalid study. External validity is | about applicability: if I give a dose of abx to a bunch of people | with advanced AIDS to treat an infection, and find it doesn't | work, it doesn't mean "this abx doesn't work." It means "this abx | doesn't work /in this population/. Don't extrapolate it to an | immune-competent population." | | 1. The study begins with what they describe in their registration | documents as "healthy elderly." That's a bit kind: "Sixty-two | normal volunteers, who responded to a local advertisement, were | screened. Subjects with any neurological condition, metallic | implants, claustrophobia, tinnitus, BMI <=30, high blood pressure | (systolic<=140 mmHg), diabetes mellitus, intensive physical | engagement (more than 1 hour/week) and abnormal performance in a | cognitive screening test (MMSE < 27)[32] and a test devoted to | depressive symptoms (BDI-II > 13) [33] were excluded." In short, | they started with an _anomalously_ healthy population, who likely | have a lifetime of exposure to exercise and physical activity. Do | the results here extrapolate to the general population? Do they | extrapolate to the same degree? It 's a decent question mark, | considering their results are non-significant in everything | except their "looks like false positives" brain volume measures | to begin with - even a little bit of "ehh... maybe not so much" | takes them into the realm of "no effects", alongside every other | measure in the paper. External validity is doubtful here. | | 2. Internal validity is a bit doubtful too, first for reasons of | selection bias. They recruited 62 healthy volunteers; they had 14 | dropouts. A 22% dropout rate isn't atrocious, but it's more than | enough - if it's not random - to skew a study. Their enrollment | figure describes the dropouts as almost entirely pre- | randomisation (10/14), but the study description notes that 6 | drop-outs were due to failure to achieve frequency of adherence, | which clearly had to occur post-randomization, and 2 due to | dissatisfaction with group assignment (obviously post- | randomization). 6 got seriously ill - I'd love to know _in which | group_ , and with what. | | 3. Their way of controlling for equivalent physical load was to | measure heart rate twice. On the one hand, not crazy. On the | other hand, if you've ever seen your HR during a workout session, | you'll see how noisy that is - and with a sample of a whole 38 | pairs, that's a relatively huge amount of noise. Moreover, it | doesn't appear that they used that to guide intensity of | intervention, just "to control" (which I take to mean, to plug | into a multivariate model at some point - except they don't, as | they describe the covariates they plug into their model to be | age, sex, and intracranial volume for brain volume t-tests) I'm | skeptical this is an adequate control - I'd at least have wanted | a time-weighted average HR. | | 3.b. The sports intervention had one effort-controllable | component (sport bike), but had 3 different components. It's not | at all clear they could capture the effort under the regimen | above, especially as the relatively light strength exercise that | the elderly tend to tolerate is the place where I'm most | suspicious of them failing to capture an effort delta. | | 4. The differences in brain volume swung in different directions | in each group, without making an awful lot of sense (more right | cerebellar development in standard exercise group?? So, | asymmetrically, the less-coordination-demanding intervention | showed more development of the primary coordination center of the | brain?). But more generally, looking at supplementary table S3, | note that dancing showed improvements in anterior and posterior | white matter, and standard exercise in temporal and occipital. | The brain isn't that cleanly delineated - to find such | statistically strong effects in such broad brushstrokes sets off | a red flag for me. | | The fact that there was scattered growth *in both groups suggests | we're looking at false positives. Not precisely a new problem for | this study methodology. Their p-threshold of .001 is considered | best-practices (aka, the bare minimum) for cluster-based | adjustment of multiple testing in neuroimaging: so that's good. | They don't report the p-values on their brain volume testing; | table S3 simply notes "p<.001". An actual effect size would be | better, but hard to get with cluster-based thresholds - they're | sensitive to "any signal, at all, is it there?" but they're | shitty at locking down precise volumes. | | 5. Dance group had lower BDNF plasma at baseline vs. standard | exercise (1500 vs. 2100) (p .14), and equal at post (2200 to | 2100, p .6). In short, they showed regression to the mean in the | dance group. They report this as "the dance group had an increase | in plasma BDNF from baseline." Serum levels likewise were not | significantly difference pre and post between the two groups | (dance went from 35K to 36K, sport went from 30K to 29K). In | short, nothing happened. But they hid the "fucking nothing | happened" in supplementary table 4, and dressed it up real pretty | in the included figure 4. | | 6. Cognitive outcomes, the only thing that actually matters here: | no differences. | | 7. At least some physical fitness differences? No, none there | either. | | TL;DR they found nothing, made some misleading figures out of it. | There are no perfect studies, but this one just boils down to | "found nothing, needed publication." | PaulDavisThe1st wrote: | Obligatory favorite obscure book that everyone should at least | have read a Medium summary of citation: | | https://www.amazon.com/Keeping-Together-Time-Dance-History/d... | | Super-tiny summary: humans have used coordinated rhythmic | movement and the feelings it evokes as an aid to build | communities and create efficient synchronized behavior. This | behavior may even predated the human separation from other apes, | and there is some evidence that certain other modern apes may use | this too, though to a more limited degree. | | If this is truly such an ancient mechanism (the author's case is | not ironclad, but good), it wouldn't be surprising to find | connections between "coordinated rhythmic movement" and brain | function. | hannob wrote: | Looking at this: | | "Dancing compared to conventional fitness activity led to larger | volume increases in more brain areas, including the cingulate | cortex, insula, corpus callosum and sensorimotor cortex. Only | dancing was associated with an increase in plasma BDNF levels. | Regarding cognition, both groups improved in attention and | spatial memory, but no significant group differences emerged. The | latter finding may indicate that cognitive benefits may develop | later and after structural brain changes have taken place." | | May I translate: They saw improvements in things they could | easily measure. They hope this translate into improved cognitive | ability. But it actually didn't. But they still hope it'll do | that later. | | (FWIW: I'm an active Lindy Hop dancer - ok, I have been before | covid... - I love dancing and I am really looking forward to when | I can visit dance festivals again.) | MagnumPIG wrote: | No wonder science journalism has a hard time keeping to the | facts, even with direct access to the paper we're upvoting and | misunderstanding a paper of trivial significance... | dnquark wrote: | My first dance teacher used to refer to a similar study from 10 | years ago in NEJM | (https://www.nejm.org/doi/full/10.1056/nejmoa022252); his | commentary is at | https://socialdance.stanford.edu/syllabi/smarter.htm | | But yeah, getting into lindy hop 15 years ago was literally the | best thing that ever happened to me.
