The terms “strengths & weaknesses” and “rate limiters & enhancers” are often used in different contexts within movement and performance analysis.
Strengths and weaknesses are commonly used in the dominant approach to identify areas where an athlete excels (strengths) and areas where they struggle or underperform (weaknesses). Strengths might refer to physical attributes like force production, speed, or agility, or technical skills like accuracy in shooting, dribbling, or tactical awareness. Weaknesses are the areas that limit an athlete’s performance or ability to execute certain tasks effectively, like poor force development, coordination, or decision-making in critical moments. These concepts focus more on an athlete’s individual abilities, often without a consideration of the constraints or environment within which they perform. Rate Limiters and enhancers refer to factors that either limit or enhance the athlete’s performance within a given context, considering the interaction between the individual, the task, and the environment. This approach emphasizes how different constraints affect movement and decision-making. Rate limiters are factors that constrain or limit an athlete’s ability to perform optimally. Rate limiters can be:
Enhancers are factors that facilitate or enhance performance. They are often the same aspects that allow an athlete to perform at their highest level:
Strengths and weaknesses typically describe static individual characteristics and abilities, while rate limiters and enhancers focus more on dynamic elements and their relationship to the athlete’s performance in a specific context, factoring in the task and environmental constraints.

What is a movement signature?
A movement signature refers to the unique patterns or characteristics of an individual’s movements. It represents how someone moves based on external and internal constraints. The individual’s unique movement patterns (or signature) emerge as a result of the complex interaction between personal abilities, the task at hand, and the environment. Individual constraints include physical and psychological factors:
These constraints interact to guide and shape the development of a movement signature. Instead of coaching exact positions, the coach should manipulate the constraints to encourage adaptive learning and problem-solving. The goal is to allow the athlete to discover their optimal movement solutions through experimentation, practice, and adaptation to the dynamic constraints. When applying ecological dynamics to motor learning, the focus is on how athletes learn to attune (awareness) their perceptual-motor skills to the information available in the environment. There’s an emphasis on the adaptive processes that occur over time through practice and experience.
On the other hand, motor performance examines how an athlete’s current state (physiological, psychological, etc.) interacts with the affordances (movement opportunities) provided by the environment. There’s a recognition that performance is a result of the real-time interactions between the individual, the task, and the environment. In summary, motor learning involves the adaption of skills over time, leading to relatively “sticky” (permanent) changes, while motor performance refers to the immediate display of those skills in a specific situation. Dynamic Correspondence is a concept developed by Russian sports scientist Yuri Verkhoshansky. It focuses on the idea that training patterns should be highly specific to the movements and physical demands of the sport for which an athlete is preparing. The principle is rooted in the belief that the best way to improve performance in a particular sport is to closely mimic the sport’s movements, speeds, and muscular patterns during training.
The 5 Criteria of Dynamic Correspondence: 1. Accentuated Region & Specificity of Joint Actions:
Task decomposition and task simplification are strategies used to facilitate the understanding and adaptation of motor skills in relation to the dynamic environment.
Task decomposition involves breaking down a complex motor skill or movement task into isolated components. For example, performing closed change of direction drills where the conditions are predictable.. Task simplification entails modifying the task or environment to reduce its complexity, making it more appropriate for the individual. This can involve manipulating constraints like rules, velocities, playing area or number of participants. It affords opportunities to practice and develop specific elements of the skill in a contextual setting, gradually building up the experience before exposure to complex situations. For example, 1v1s with smaller workspace, simple role specific tasks and manageable amount of unpredictability. |
