Why is movement variability beneficial for skill acquisition and execution? What distinguishes "good" from "bad" variability in movement?  How do different coaching/instructional methods (e.g. ordering practice conditions, cueing, differential learning, and manipulating constraints) compare in terms of their ability to encourage functional variability? When should we be trying to maximize variabil...

A discussion with Mark O'Sullivan, Coach with AIK Football in Stockholm. We discuss Mark's concept of football interactions and how it relates to practice design and affordances, and the "race to the bottom" in talent identification.   More information about my guest: https://footblogball.wordpress.com/category/mark-o-sullivan/ https://twitter.com/markstkhlm   More information: http://perceptionac...

A look at research investigating the effects of assisted/guided movement on skill acquisition. Can experiencing the movement pattern of an elite athlete facilitate motor learning in a novice? Is it better to use assistance to reduce or augment errors? Articles/Books: Can Robots Help the Learning of Skilled Actions? Robot assistance of motor learning: A neuro-cognitive perspective Robotic guidance...

A look at how Bernstein's famous phrase "repetition without repetition" revolutionized how we think about motor learning. And an introduction to a few extensions of Bernstein's ideas including coordinative structures and the uncontrolled manifold hypothesis. Articles/Books: Dexterity and Its Development The Bernstein perspective: II. The concept of muscle linkage or coordinative structure The blis...

A look at Bernstein's theory of freezing/freeing degrees of freedom during skill acquisition and some research which has tested these ideas. Articles/Books: Dexterity and Its Development Free(z)ing Degrees of Freedom in Skill Acquisition Conscious Control Is Associated With Freezing of Mechanical Degrees of Freedom During Motor Learning Throwing Skills: Analysis of Movement Phases in Early Motor L...

The first episode in a series looking at the contributions of Nikolai Bernstein to our understanding of motor control and motor learning. What were Bernstein's "problems? Is finding solutions to these problems really what effective coaching is all about? Articles/Books: https://en.wikipedia.org/wiki/Nikolai_Bernstein Dexterity and Its Development The Bernstein perspective: I. The problems of degre...

A look at the Differential Learning approach to skill acquisition. Is maximizing movement variability by preventing repetition and correction the optimal way to design practice? How does this differ from the Constraints-Led Approach?   Articles The Nonlinear Nature of Learning - A Differential Learning Approach Time scales of adaptive behavior and motor learning in the presence of stochastic pertu...

A look at some recent research examining contextual interference, blocked vs random and variable vs constant practice.  How should coaches put these concepts into practice?   Articles Quantifying Contextual Interference and Its Effect on Skill Transfer in Skilled Youth Tennis Players Effects of practice schedule and task specificity on the adaptive process of motor learning Exploring the applicabi...

A discussion with Leah Robinson, Associate Professor of Movement Science from the University of Michigan. Topics include the importance of fundamental movement skills, how these skills should be measured, perceived motor competence and interventions for promoting movement in young children.   More information about my guest: http://www.kines.umich.edu/directory/faculty/leah-robinson http://www.cma...

Looking at research that has evaluated the Constraints-Led Approach (CLA) to coaching. How effective is this approach? What effects do changing constraints actually have on performance? How does the CLA compare to other more traditional coaching methods?   Articles Scaling the Equipment and Play Area in Children's Sport to improve Motor Skill Acquisition: A Systematic Review Switching tools: Perce...

What processes are involved when movement coordination is self-organized around constraints? How does the performer take into account their own action capabilities? What is the best way to design practice according to these ideas? A look at behavioral and ecological dynamics.   Articles The Dynamics of Perception and Action An Ecological Dynamics Approach to Skill Acquisition: Implications for Dev...

The first in a 3 part series on The Constraints-Led Approach to Coaching. What exactly are constraints? What are some common misconceptions about them? Why is understanding the theory behind them critical for using them effectively?      Articles Constraints on the development of coordination Change of Direction and Agility Tests: Challenging Our Current Measures of Performance   More information:...

A discussion with Brian McCormick, Head basketball coach at Broward College in Florida.

Is motor learning a single process that occurs at one time scale as suggested by the famous learning curve? Or are things happening simultaneously at multiple time scales, with some adaptations taking seconds and others years? What might this mean for coaching?   Articles/links: Warm-up Decrement in Performance on the Pursuit-Rotor The second facet of forgetting: A review of warm-up decrement The...

Just in time for the start of the World Series: a look vision and gaze behavior in baseball batting. Which aspects of vision are critical for hitting? Do great batters have superior vision? Where do good batters look before the ball is released?   Articles Defining elite athletes: Issues in the study of expert performance in sport psychology The visual function of professional baseball players Vis...

What are the key differences between describing an athlete's movements, an athlete's knowledge about those movements, and the instructions used by a coach to facilitate those movements?
