comment Exercises to improve balance when kicking
@JediWitness, sorry, this sounds too much like a "my art is better than your art" argument rather than an attempt to address the original question. If you'd like a more open-ended discussion, perhaps the chat would be a better place to present your points.

comment Exercises to improve balance when kicking
@JediWitness, your comments are noted. The OP was asking about balance, not power or leg sweeps. Was your intent to make some point about balance in your comments?

comment Which kind of breath provides the most striking power?
@stslavik, that's not true. Every aspect of human-related physics is quite easily measurable. Impact energy, pressure and impulse are all directly measurable. Velocity can be observed with a high speed camera (see any episode of Mythbusters for an example). The mass of the system components shows up in all of the related formulae; just solve for 'm'.

@BerinLoritsch, then it's an unanswerable question without that context. General aimless discussion is specifically disallowed in the FAQ.

comment Which kind of breath provides the most striking power?
"Power is how much force is transferred to the target": again, you're thinking of energy.

comment Which kind of breath provides the most striking power?
This is incorrect: "Power is force over time." You're thinking of work: en.wikipedia.org/wiki/Power_(physics)#Mechanical_power The correct definition is "Power = Force times velocity = Work over time." Power is also a poor choice as a physical principle due to it's lack of conservation. Try kinetic energy instead = 1/2 * mass * velocity^2.

comment Which kind of breath provides the most striking power?
@BerinLoritsch, so it's an unanswerable general question according to the FAQ: martialarts.stackexchange.com/faq#dontask There are too many variables, undefined terms and a missing metric (what is "best"?).

comment Which kind of breath provides the most striking power?
"No, I can't define the methods of breathing that I refer to" - if the terms aren't defined, then this is not an answerable question.

comment How do I coach her mindset to better suit karate competitions?
Totally agree: if you're engaged, you can't give objective feedback. That said, you can talk about "what worked for me" and see if that's useful. Realize: it might not help. Her issues are not your issues.

comment Correct usage of the title “Master”?
+1 Very true - in class, the students call me "doctor Cross" - if they called me "mister Cross", I and my two sons would all turn at the same time....

comment Value in Practicing Spinning Kicks
@RoryAlsop, you're welcome. I agree - that bout is fascinating and terrifying at the same time. Both of those men are far outside my weight class (and I'm in an age bracket where I know better). The forms on your site are interesting - I had never seen how cross-shaped chon ji really is. On a side note, the bounce that the performer does before every move is very distracting for me. Different styles....

This question is too localized - how do you define "correct"?

comment How helpful is it to film yourself during training and analyze videos after training?
@dmckee, well we have to pick a word. I do a fair amount of public speaking as well and had to help edit a video presentation of one of my talks. I was ready to claw out my own eyes before we were done.... ;-)

comment What's this posture called, and does it signify something
@knb, you are welcome. You aren't wrong in noticing the difference between the form and the picture. Personally, I would call that a variant that, in real life, would certainly be adapted to the situation of the moment (i.e., block high if the attack is coming high). Your mileage will obviously vary.

comment Value in Practicing Spinning Kicks
@Trevoke, if you're speaking about the overall population, sure, they are not inclined to back kick. They are, however, inclined to get their head out of the way. The OP was asking from the point of view of someone who is being trained in spinning kicks and does not understand the motivation. That is not the average person. So, when I say "you" in that sentence, you can substitute "David H. Clements."

comment Are students with disabilities tested differently?
Check the comments on that post, particularly Robert's comment "But, if your question is intended to gather a list of equally relevant answers, and you don’t expect one answer to be the most applicable, it should be a community wiki anyway. Community wiki on a “list of X” question suggests that the value of the question is in having the list of answers as a collection (i.e. a collaboration)." Is it possible to answer this question definitively? As far as I can tell, the answers "yes", "no" and "maybe" are all equally valid.

This is another wiki question. All answers will be subjective.

@Tomas, thanks. I was trying to be brief without being rude. I succeeded in at least one of those two. ;-)

comment What benefits (if any) are there when listening to music while practicing? And does it depend on the style?
This is a wiki question: there is no yes / no answer. Every "answer" is going to be completely subjective.

comment Are there musical instruments which, when practiced, noticeably increase martial arts skills and performance?
@KeithNicholas, I'm going to have to agree.
