Beyond Optimality: Embracing Emergent Adaptation. A conversation with Madhur Mangalam.

This podcast was recorded in response the publication of 'The myth of Optimality in Human Movement Science' by Madhur Mangalam.

I recorded this episode some time ago but it has been a tough year and I have not published any podcasts. I lost my beloved River Tiger this year - it's still very raw but I do want to discuss that in another episode. My motivation is stronger for continuing to explore skill adaptation in equestrian and adventure sports so despite the need to prioritise my PhD thesis, I will endeavour to publish some episodes this year.

The "myth of optimality" in human movement science critiques the idea that there's one "perfect" way to move, arguing that evolution produces sufficient adaptations, not perfect solutions, and that movement is dynamic, context-dependent, and adaptive. This flawed concept, often used in biomechanics and motor control, ignores the body's ability to find flexible solutions based on task, environment (e.g., running on a track vs. trail), and internal states (fatigue), proposing instead that performance emerges from complex, multi-scale processes, not a fixed, optimal blueprint. 

This discussion explores the concept of optimality in human and equine movement sciences. Madhur Mangalam, an assistant professor of biomechanics, critiques the optimality framework, arguing it oversimplifies complex movements. He emphasises the importance of variability and context in movement, citing his viral paper on the myth of optimality. Marianne and Madhur discuss the need for a more empathetic, constraint-aware approach in coaching and the limitations of lab-based research in capturing real-world movement dynamics.

Madhur Mangalam is an accomplished Assistant Professor in the Department of Biomechanics at the University of Nebraska in Omaha. He has a stellar academic background, earning his Bachelor's and Master's degrees in Life Sciences from the prestigious Indian Institute of Science Education and Research in Pune, India. His insatiable curiosity and passion for understanding the human mind led him to complete his Ph.D. in Psychology at the renowned University of Georgia in Athens, followed by rigorous postdoctoral training in Neuroscience at Northeastern University in Boston.Dr. Mangalam's research pursuits are at the forefront of interdisciplinary innovation, primarily focusing on unraveling the nonlinear dynamical principles that underlie perception-action mechanisms and embodied/embedded cognition. His scholarly journey is marked by a commitment to advancing our understanding of these intricate processes. Furthermore, he is a pioneer in developing cutting-edge nonlinear analytical methods, which play a pivotal role in uncovering and deciphering these fundamental principles. With his exceptional academic journey and dedication to pushing the boundaries of knowledge, Dr. Mangalam continues to make impactful contributions to biomechanics, psychology, and neuroscience.
