Dynamic correspondence

Do movement skills influence functional correspondence?


Dynamic correspondence

Originating from within the strength and conditioning literature the concept of ‘dynamic correspondence’ can be seen to raise many of the same elements of the ‘functional/non-functional’ debate heard elsewhere.  Dynamic correspondence is a means of profiling any particular sports skill with regards to such factors as the speed, force, and range of motion employed within it. This process allows for an exercise to be designed to enhance a certain part of the original skill considered. A sprinter in the blocks may need to enhance their ability to produce force at the specific point in range of the musculature responsible. A dynamic correspondence exercise would be seen to address this issue and ultimately enhance the overall performance of the sprinter’s start.

Functional correspondence?

From a movement control perspective perhaps the concept of a ‘functional correspondence’ is worthy of attention. This concept may help those who see non-functional exercise as lacking merit as a means to improve movement quality.  Employing so called ‘non-functional’ movement strategies to alter daily and sports function could be likened to the use of the exercises that result of dynamic correspondence.

The Performance Matrix movement analysis profiles clients’ movement skills. Through this process deficits within their movement control are highlighted which can then be pulled out for specific attention (just like the force production abilities in the sprinter’s start). Depending on the profile of the movement impairment identified ‘non-functional’ loading strategies, ‘non-functional’ body positions and ‘non-functional’ recruitment strategies may need to be employed. A good example is supplied by ‘sequence of contribution’ (which synergists contribute when to a movement). If a multi-joint mobiliser is seen to both initiate an action and contribute so excessively as to produce other unwanted movements and rigidity during an activity of functional, postural loading a ‘non-functional’ fix is required.  An appropriate exercise will need to alter the recruitment mix of both the when and the how much, a change difficult to achieve during functional exercise. Functional correspondence, just like dynamic correspondence, may be a concept that allows any movement to be profiled, deconstructed and subsequently rebuilt so that performance is resilient and robust across the movement control continuum.
