I’m in Dr Grays HSE program right now and if there’s one thing I can say, it’s laid out so well. As soon as I come up with a question, the next lecture answers it.

This is Excellent! Thank you for breaking it down. Given your experience with hockey any chance you could do something similar for youth hockey players (not goalies)? The method and the principles would stay the same, but I’d be very curious to see how you create representative designs for younger players that already have too many constraints due to their lack of game knowledge and skills?

Great video!

Googled these guys and just realized Jeff Quail's the guy who invented the Shocknife. Go Canada.

Great chat, thanks!

I've been trying to think of good ways to apply this to martial arts. Do you by chance have any opinions or experience with that? Like is there anyway you could step through how you would teach a roundhouse kick with constraints, and then how you would design safe sparring games with constraints. I'm really curious to see a few examples so that I can get an idea of what it might look like and then go from there.

Hi Rob!! Appreciate all the information you are putting out! I think you mentioned a having a patreon? Could you share the link for that??

28:04 this seems completely obvious. Gotta move the hand, etc. Yet it just blew my mind.

Good stuff.

Fantastic stuff. Great to see Coach Souders on Perception Action again.

Really enjoyed this Thanks guys

CLA definition of "skill" 4:35 to around 5:00 to 6:00. I would stress or add that skills have a component of prediction/anticipation accuracy more than just dexterity. I suppose that has to do with selection though... 9:10, 4 Key goals of CLA

Damn no way

Introduction and Overview Greg Souders, a submission grappling and Jiu-Jitsu coach, discusses his coaching philosophy and methodology. He emphasizes an ecological approach, focusing on simplifying Jiu-Jitsu into basic human behaviors and the overall system of interaction. Coaching Philosophy Traditional Jiu-Jitsu training involves learning moves and techniques in isolation. Greg advocates for a more holistic approach, considering the entire system, including environmental and psychological factors. He focuses on immobilization as a fundamental concept, leading to more complex skills like strangulation and breaking. Training Methodology Greg uses games and tasks to teach skills, starting with end states and working backward to more complex situations. Training involves high variability and frequent practice to develop adaptability. He emphasizes external focus and immediate feedback based on the opponent's reactions. Skill Development Training progresses from low variability situations to more complex and dynamic interactions. Greg discusses the importance of understanding and manipulating relationships between body segments (e.g., wrist, elbow, shoulder). Advanced Training Advanced students face more complex tasks and longer practice times to enhance their skills. Variability and novelty are constantly introduced to challenge and develop higher-level skills. Deception and Strategy Deception is a crucial aspect of grappling, involving movements that appear to be one thing but result in another. Greg teaches students to understand and manipulate their opponent's responses through strategic actions. Individual Constraints Training is tailored to individual constraints, such as size and body type. For example, larger athletes may need different strategies due to their physical limitations. Use of Language and Communication Consistent language and communication are used in both practice and competition to maintain focus and reduce cognitive load. Greg avoids introducing new terminology during competitions to prevent confusion. Intrinsic Dynamics Greg recognizes the importance of intrinsic dynamics, allowing students to find their own solutions within guided parameters. He uses practice design as the primary intervention tool to facilitate learning. Film and Feedback While not extensively used in class, students are encouraged to film their practice sessions for self-analysis and improvement. Ecological Approach and Learning Theory Greg integrates ecological dynamics principles, such as invariants and attractors, to guide his coaching. He emphasizes the importance of continuous learning and adaptation. Further Studies Suggested Exploring Ecological Dynamics in Combat Sports Investigate the application of ecological dynamics principles in various combat sports, comparing different training methodologies. Variability in Skill Acquisition Study the impact of high variability training on skill acquisition and performance in grappling and other sports. Deception and Strategic Movement Analyze the role of deception in combat sports, including the psychological and physical aspects. Intrinsic Dynamics and Personalized Training Examine how intrinsic dynamics influence training outcomes and the effectiveness of personalized training approaches. Use of Technology in Training Explore the benefits and challenges of using video analysis and other technologies in sports training. Impact of Environmental and Psychological Factors Investigate how environmental and psychological factors affect performance and learning in combat sports.

Does eco vs IP make anyone else see Aristotle v plato?

Outstanding discussion. Greg is so articulate in his explanations. I hope to be as concise as he is one day. Thank you for having him back on Rob!

05:48 I see you constraining your language Greg. The phrase mentioned in the other podcasts was: "We came to fight, motherfucker!"

The amount of knowledge, references, and work that these two have put it into their relative communities for FREE...it's just something we should all be very thankful. Another great podcast to watch!!

Another great discussion with Greg! I can watch these everyday and still learn something new. Thanks for these!

Love this, trying to apply ecological dynamics to bouldering. Greg's changed my bjj a lot even though we've never met.

Legendary podcast

Hi all. Does anyone know where i can get the Michael ashford interview? I looked for the podcast mentioned but cant find it. Assume rob has it up somewhere? But cant seem to find either! Many thanks.

I would love to hear your thoughts on “sport science” culture and forceplate/isokinetic testing research and applied testing to measure “neuromuscular profiles”… it seems absurdly reductionistic and completly goes against everything Perceptual motor landscape/DST to use a jump test across every sport to as a proxy for readiness… thoughts?

So its a case of so many different things to consider before you execute a shot (tennis) all in the space of a second and the technique is the actual last thing. Everything else before that drives your decision of how to hit your shot? Heavy technical focus from a drop feed ect is a like tring to answer a question before youve been asked it...

Hi ....First of all, I love your energy...it's spot-on!!! Secondly, what are your thoughts and recommendations on nutritional supplementation to maintain wellness after your therapy, in addition, are you open to receive new cutting-edge information on maintaining our own stem cell health?

Thank-you 🙏. Great, thought-provoking look at Physio from a more ecological POV. (I was already a huge proponent of UltimateInstability Aquabag)

Hey Rob, I love your work, although I do challenge your point on prediction. it seems like both methods use prediction, which could be defined as probability of success that in one scenario, you have one state with a static probability and in the scenario favor, you take into consideration many static steps over time this increasing probability over time. This is exemplified in your statement of continuously, taking in new information and making micro adjustments. Please let me know if I am understanding this correctly.

BJJ Mental Models brought me here.

Thank you

Thank you for sharing.

Incredibly useful, thank you for providing so much amazing content Rob!

Nice! I just watched a 5-year old interview with Alex Sarama last night, and here he is today on one of my favorite podcasts.

Make your other books also as a Audible + a PDF. Great work sofar from you! Keep it up✌️

Hey Dr. Gray, your audio cuts out pretty often so it was hard to hear when you were explaining :(

Rob, Thank you so much for sharing these conversations with us. I'm learning so much and using them often as a coach and coaching educator. Cheers.

6:39, definition of constraints 7:19, says that adding constraints can make picking up a new movement pattern easier because it reduces the possible options (as long as it also leaves you with the best one to do) 7:50, time dependence, stability vs adaptability 8:34, 10:09, task constraints 12:54, 13:43, 15:08, key 7 17:24, myth busting

Hi! I really appreciate the information you provide! Is there any information, study, or video about whether I should train with training partners who are at a lower level, the same level, or higher level than me?

Interview about OPTIMAL theory is episode 80.

this is something so much similar to what J.R Kantor understood about human behaviour in his work interbehaivourism

I wonder how much better the youth of today will be at sports now that you can go down to Best Buy and get a VR headset. What are they losing by relying on VR?

I really really like these videos it can just be tricky to understand you sometimes when you speak so fast that you trip and mumble. I only say this as I find it frustrating due to the information being so excellent 🙏 thank you for this channel!

👍 way to go, a great talk and hope that more and more coaches and instructors find this. Ecological dynamics with CLA is the skill accelerator and it really fast-tracks learning. We’ve been developing this now for about five years in self-defense context as well as in security/LEO training as well as in military with ”Zero Distance Solutions”-context. Super work and I do hope that we can help a lot of martial artists & combatives to learn faster🙏

This is brilliant , however I don't claim to understand everything

Rowing has been using an ecological (including constraints led) approach for decades if not more than a century. If you want to talk about it I'm happy to oblige. I think you'd find that our training already supports the style of learning you're advocating.

Hey, Rob! Cool study! I’m curious as to the utility of this study with respect to the ecological approach. If we’re staying true to the EA, it would seem that we should be focused on successful completion of the task no matter how the movement looks (movement quality). My initial thought was that maybe these coaches could be better at identifying invariants and therefore be better able to constrain the environment to afford, however it seems that invariants would be much more broad than something like shoulder internal rotation speed or other biomechanical features. Thanks for all you do!

Would love to see this study design, measuring validity as a secondary research goal - comparing the coaches’ scores to efficiency of force production.

I would of like to hear you go deeper on your last question. What to do when a player responds to an affordance with a negative reaction? Going through that now personally
