    One thing that I can't seem to reconcile is how individual practice away from the rink affects skill acquisition. Many, if not most, really successful players presumably practiced a ton away from the rink. If someone is shooting pucks or stickhandling on their own without other players/constraints, is this of no value? How can someone create constraints? Shooter tutors? Or other objects blocking net? In terms of variability, shooting from different distances, or angles would apply. For stickhandling this gets tough...Any thoughts?

    Thanks, Rob, for reviewing our study. As you highlighted, the key lies in testing under 'constant' conditions. We tried to test the effect of variable practice even when the test itself had extremely reduced variability. In fact, the group you refer to as the control group did constant practice. Although we probably shouldn't have called it that. As you correctly point out, every time the participant picks up the ball, they do so in a slightly different way, they never repeat the same range of motion…, and even during the final throws, they might be more fatigued (not measured) or even more bored. So, we should have called it the extremely low variability group… Despite several calls to consider the characteristics of the skill and the learners when applying variability, few studies still address these variables. We've gained valuable insights from this experiment, and hope our new study, which dives deeper into this issue, will offer more and better. Coming soon ;-) Thanks for sharing your perspective.

    10:10, This reminds me of a study I heard about how people who develop OCD are extremely disturbed by the compulsive thought and this leads to the development of obsessive behaviours... I believe an intervention of mindfulness meditation was effective in lowering their anxiety triggered by the thought, by noticing it and accepting it. This sounds rather similar IMO

    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?

    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.

    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

    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.

      Yeah you see how important constraints and affordances are when you see pro level boulderers solve the same problem using totally different movement solutions. It seems to me much of bouldering is already pretty ecological since exploration of movement options is highly encouraged.

    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...

    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.

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🙏
