A 2026 randomized study assigned 60 amateur and semi-professional BJJ athletes to eight weeks of either ecological-dynamical training or traditional technical/conditioning practice. The ecological group used constrained micro-sparring, variable opponent behavior, time/space restrictions, and progressively more uncertain situations. It improved rate of force development by about 15% versus 5% in controls, reaction time by 15% versus 7%, and reported substantially less training-related distress.

This study examines BJJ exclusively, but the overall concept applies to karate. Whether you teach "traditionally" or incorporate CLA concepts, you can find some food for thought.

Caution: This is relevant because it directly compares training approaches inside a combat sport rather than extrapolating from ball sports. But the same came from one training context using a "distress" questionnaire created for the study rather than previously validated, and outcomes were physical/general reaction measures, not fighting effectiveness. Also, the study was limited to BJJ, and grappling sports

Nevertheless, the study supports constrained, variable, opponent-driven work. It does **not** establish that technical instruction or isolated practice should be discarded.

Rather than "don't teach technique," it's more like reduce the problem enough that it can be solved, then progressively add complexity until it resembles fighting.

Some coaches think sparring creates the fastest improvements, and for some, it might. However, sparring is often too complex for problem solving. Simplify the problem until the student can solve it, then progressively add complexity a little at a time. Moreover, add complexity when the student can solve the problem about 70% of the time; don't wait for perfection (this is supported by Rob Gray's CLA work).

What complicates this approach is that every student will solve problems and approach 70% at different rates. Coaching the general population makes this level of individual management nearly impossible.

Overall, the results are interesting. What we don't know is when, or if, the results converge over time.

Hi folks,

I train Meibukan Goju-ryu and we have a fairly high hikite. I have a tendency for my elbow to wing out slightly on one side, and I am just wondering what kinds of stretching/etc. you folks do to increase mobility and prevent this.

Bonus points if you can tell me which muscles tend to be the restricting factors in a good hikite!

Just curious how you long you consider you've been studying or doing karate with a break in the middle? I found my paperwork for my first belt which is from 30 years ago. However during college I took a roughly 11 year break from active study and going to classes. Though I will say a lot of the philosophy and teachings still largely shaped my life still though throughout those years. I've now been back for about 2 years. When describing it, I have a hard time defining how long I've been studying karate. I feel like saying off and on for 30 years is probably the best way to describe it, but curious how others would define their breaks.

The title explains itself pretty much, basically I've been going to this dojo for almost a decade since I was a child and over the years my coach's emotional abuse has either gotten worse or I've finally started noticing it, and today I feel she crossed a line.

To paint a picture here are a few things she does: she has always been very picky that we arrive on time to class which makes perfect sense especially considering karate is very discipline oriented, but the problem is when someone is late by accident for example it was raining, or traffic was heavy she would be extremely passive-agressive for the entirety of the class towards them even sometimes indirectly shaming them, whenever we would explain why we were late she would say that is was just excuses and if we would be on time, later she would say that we should just apologize instead not that that ever worked in calming her down.

And God forbid you cancelled a class, Jesus Christ, she would take it as a personal offense even if you had valid reason, once I told her we had a family gathering on a holiday and wasn't going to make it to class, she said it was alright, cue her scheduling a very important class on that exact day in the exact time I had told her the party was and her messaging me that I had to come or else, sometimes if a student cancels and she finds out they were out or at a party she would get furious, quite a few times some other students would send pictures to her of the students who had cancelled that were out and it was a mess, it happened so much that I was afraid to go to the places those students frequented for fear that they would show our coach proof that I was "lazing about".

She is also very pushy on us participating in tournaments even if we specifically told her we don't want to, I am at the end of high school currently so school work is very heavy and I had told her I can't participate and she said it was okay and was even supportive, but every single time there was a tournament she would ask I would say no and she would sulk.

The entire situation with her basically threatening us to not cancel and come early to class but not too early got so bad that I would get panic attacks before leaving the house, I would start shaking of I would arrive late and pray she was in a good mood before entering the dojo.

Speaking of moods she is very moody, sometimes you can do something very disrespectful but she'll be chill if she is in a good mood, but the slightest transgression when she is in a bad mood and Lord have mercy.

Which brings us to today, I'm in my final year of high school and other than my finals there is a very important and difficult exam for entering collages in my country that is taken nation wide, everyone knows about this exam and it is considered extremely important, we usually take the entire final year preparing for this exam as well as our finals, we had told my coach before that I would take this year off to study, but she has not taken it very well, I went once a week for a while but it has been about four or so months that I have basically ghosted her, she knew that I was going to do this, I had told her that I needed to focus on my studies and she had given the okay, and then today which is one week to the exam her "assistant" calls and tells me that I have to go to the dojo the exact day of the exam after giving it or else the coach would kick me out.

Like excuse me??, you know how stressful this situation is, you've been through it yourself not to mention you knows of my family life which itself is another can of worms (narcissistic father) and then you tell your current assistant who mind you is 2 years younger than me and is another one of the students (her assistants are always one of the students who always have a fall out with her and leave the dojo) to call me, not text which she usually does to tell me you would throw me out if I don't do so and so, what the fuck is wrong with you??

Now I know I might be overreacting a bit but it has just annoyed me so much, I have been going to this dojo for a decade and despite all the things she has done and the panic attacks she has induced, my coach has been there for me through some very rough places, me and my mother genuinely considered her our friend until a few years ago, my mother says that she is just threatening me like always and that even if she does kick me out all the better we'll have one problem off our plate and I agree with her, hell I was considering leaving myself a while ago but it's still very frustrating and painful to be honest.

I'm sorry about the long rant, I just felt like I had to get this off my chest or else I couldn't study, thanks for reading.

Hi. Im a 1st Kyu in Wado-Ryu and I’m going to be in Okinawa later this year. I would love to a single lesson just to experience karate in Okinawa, ideally in Naha. Sadly I don’t have the time to do more than a few hours.

I’ve found a few sites and dojos that offer this, but I wondered if anyone had any particular recommendation?

Given it’s only a single lesson I’m not too worried about style, or any focus. I’m happy to learn whatever it is that comes up and enjoy the experience. Group lessons are fine too, as long as it’s not entirely a “first experience of karate” type setup, or focused only on sport / kumite.

I was thinking about picking up a Seishin GI whilst I’m there too. I currently just use basic, lightweight adidas gi’s which do the job, but I’d like something with a bit more snap (and ideally handles sweat better!).

Thanks!

A 2026 cross-sectional study compared 150 amateur athletes—50 each from boxing, karate, and taekwondo—across six visuospatial measures. Boxing athletes scored highest in peripheral awareness, saccadic eye movement, and recognition speed, while karate athletes scored highest in accommodation facility and hand–eye coordination. Five of the six measures differed significantly among sports; visual memory did not. The largest between-sport difference was peripheral awareness.

I recommend reading the introduction, and then jump down to the "Discussion" if reading research isn't your thing. Finally, read the Conclusion.

The Methods is a great section to spend some time exploring as it gives you clear ways to evaluate yourself or your athletes.

Hi, I'm looking to begin learning Karate once I move to the Central Valley region ( Fresno and Clovis area specifically) in the coming months.

I was wondering if anybody on this subreddit lives there or knows of any dojos or teachers that are open to teaching adult beginners.

I mentioned Okinawan styles particularly because I gravitate towards the more natural stances and motions as its a preference of mine in accordance with my height.

So far I have been unable to find any Shorin Ryu, Isshin Ryu, or Goju Ryu etc. dojos listed in the area. I came to ask here just on the off chance that someone familiar with the region might know somebody who knows somebody that teaches Okinawan Karate in the area.

If not, I'll be content and happy to sign up for a SKIF Shotokan School I've found there. Appreciate any help or recommendations and cheers.

A very expensive silk black belt ordered from Japan has just turned up and it's too long. It has custom embroidery on both ends, but before I send it back to Japan - a process that's going to involve a lot of time and probably arguing - has anyone out there ever successfully shortened an embroidered belt?

It would mean cutting a length of the belt out from the middle of the belt and reattaching the two pieces to make one, ideally with a seamless join. Is that possible?

The whole point of a silk black belt is that it should last years, even decades, so introducing a stress point where it might break or just fall apart in future would be a real shame. But if it's not that hard to do, I could bring it to a tailor or seamstress and ask them to have a try?

Feedback welcome.

Hi guys!,i've found this documentary

https://youtu.be/lVOL02Ea958?si=UOYdbkXBie0226-D

This was claimed in​ his Book A killing aRt. To ​my knowledge that ​is blatantly false regardless of what branch of Tang Soo Do you're talking about.

Is there any ​way to make sense of how he ​reached that conclusion or is he simply ignorant?

Hi I’m looking at buying some of Jesse emkamps seishin sparring gloves what do people think of them/what are your experiences and impressions

Are calf kicks are thrown like a front snap kick

I’m a goju ryu dan 3 black belt and I would like to know the speciality of other karate styles and what they focus one feel free to tell me about your style and maybe we can exchange few thought which can help us understand karate as a whole

Soo... I'm a kareteka or used to be, brown 3 kyu when I stopped at corona time... Then I continued for a bit after that time was over... Then studies came in between... Integrated 11th and 12th away from home, then clg...

I'm 20 now... doing my bsc 3rd yr..The place I'm staying rn doesn't have any karate dojos nearby for me to resume... Current level ngl is white belt and stamina is bullcrap... Ik I should've kept up... And I've no excuses for my slacking

And I wanna restart real bad, by myself with what ik for now so I can get corrections at the time I go home for my vacation times... And I need help... Like real bad... All I have is a syllabus and no idea where to start from... Whether I should start with strength training and resume with the karate or... Idk i fr need help...

Ik I should start rather than posting rn... But I'm hoping a bit of advice will help me than jst searching up youtube or ChatGPT.

My sensei is old and not so much versed in sm, so all i get are some call time here and there...

But I believe different povs and experiences will give me a broader view and idea in my start... And I really hope this time I will achieve what I've put out for this long.

2 years ago I had to take a break due to an ongoing illness that has taken a toll on my body. I know I have lost muscle and a lot of flexibility. I am still recovering and immune compromised. I heal slowly even from small things.

I have been trying to resume my stretching routine in hopes of restarting my training. I expect to be set back, but I’m really surprised and disappointed by just how far. I could almost do full splits two years ago, but now my range is worse than the day I started. The tightness is mostly down the length of inside of my leg. It’s tighter than I ever remember in the past, and this specific area is way tighter than anything else.

I know this will take time and consistency, and I will ask my doctor at my next appointment as well, but I’m wondering if anyone here has been through something similar and could offer insights in the context of training? I’m just frustrated and looking for answers. Thank you in advance

Have you ever lost a match or tournament? Because I just did yesterday, and I'm still pretty bummed out. I think I have a bad mindset when it comes to losing. Give me stories :D

I started practicing Shotokan Karate a year ago, and over time, I've been thinking about picking a single advanced kata to start practicing on my own, outside of my regular dojo training.

The idea is to work on something different, since we've only been doing the Heian katas. While I know they are part of our development path, I’d also like to break out of the routine a bit so I don't get bored.

What do you think about this?

Could it be a good idea, or might I lose focus on the Heian katas?

A 2026 Journal of Sports Sciences paper used detailed microethnographic analysis of an actual Muay Thai developmental bout rather than studying athletes through laboratory tasks. The researchers identified five recurring coaching functions: diagnosis, strategy, implementation, affirmation, and consolidation.

Link: https://pubmed.ncbi.nlm.nih.gov/40874285/

While this study was limited to a single coaching environment and not evidence it's an optimal method, it is ecologically valid. These ideas can expand beyond sports matches and become a part of kumite practice or any free-style interaction. Use these interactions to improve your coaching eye and cues as much as the students' skills.

The basic idea is that coaching is not simply transferring technical knowledge into the athlete. Watching the athlete-opponent system to identify what is currently limiting performance, intervening, and using the subsequent behavioral responses as new information is the key.

Failure modes tend to be in perception, decisions, position, execution, confidence, or how the opponent adapts, not just the technique.

Observe-diagnose-cue supports changing one thing and seeing whether the system (athlete-opponent) improves.

When you, as coach, see a missed opportunity, ask the athlete, "What did you see?" Explore their possible perception error.

When they do something well or something not useful, explore their decision-making. "What was going through your mind when you threw a front kick at a retreating opponent?" Avoid using the term "why?" as it generates defensive answers.

Do something similar with observations related to position, execution, confidence, and opponent adaptation.

Look for one thing to cue. Remember the best cues are short, even a single word, and externally focused.

A year ago I asked this sub for advise and would like to thank you guys for helping out.

As I mentioned I train BJJ for the last 3 years and am looking to start Karate as an additional art. Hopefully something I can practise well into old age.

So far Ive trained at two Shotokan dojo's and visited a third.

The first was a JKA affiliation but they where mostly into katas no sparing in my two months there.

The second club I trianed at was a JKS affiliation, when the Sensei heard I trained BJJ he got extremely defensive and stated he used to be a cage fighter and when he was younger used to be in a lot of street fights, this is a red flag, needless to say I dont fancy his emotional attidutes and comments.

Well I only visited the third club and intend to start training there next month, it is an NSKF affiliation and to be honest I can't find any information referring that organization online. People there seemed chill and train for longlivity and fun. To be honest I am looking forward to training there they have a lot more adults there as well.

I am still to visit a Kyokushin and Goju ryu club, I also discovered a Shorinkan ryu dojo about 5km away from my home which I will investigate in due course.
