Perceiving movement patterns: Implications for skill evaluation, correction and development. [Percepción de los patrones de movimiento: Implicaciones para la evaluación, corrección y el desarrollo de habilidades].

Abstract

Skill practitioners such as coaches, judges, and rehabilitation specialists rely heavily on the visual observation of movement to analyse performance, concomitantly performers of movement rely heavily on kinaesthetic sensitivity to produce movements of desired precision. The observation of movement errors (by coaches or therapists) and the correction of movement errors (by performers or patients) depend on fundamentally different perceptual systems that may differ in their sensitivity, units of control and trainability. This paper first examines the skill of perceiving fundamental movement characteristics and patterns (i.e., movement kinematics) by reviewing sport expertise literature that has investigated the capabilities of both expert performers and expert observers. Important expertise related differences in visual perceptual skill are discussed with a focus on perceptual and motor contributions to perceptual skill. Theories related to the perception of others movement patterns such as common coding are reviewed with a focus on implications for skill practitioners. Limitations in the current visual observation literature are considered, in particular the need to more directly examine the perceptual capabilities of skill practitioners to reliably differentiate changes in kinematics. The critical parallel issue of the kinaesthetic sensitivity of the patient or athlete is also reviewed, highlighting the need to know the magnitude of the differences between visual and kinaesthetic sensitivities for changes in movement kinematics in order to understand some of the challenges involved in matching detection of movement pattern errors to correction of these errors. Future research directions are discussed; particularly key methodological issues which may help directly establish perceptual sensitivity.Key words: perception; observation; kinematics; kinaesthesis; expertise.

La capacidad de determinar de forma precisa las características fundamentales del movimiento a través de la observación es fundamental para ofrecer una evaluación, diagnóstico y corrección eficaces. Del mismo modo, la capacidad de controlar con precisión la ejecución del movimiento es central para la producción de patrones de movimiento deseados. La observación de errores del movimiento (por entrenadores y terapeutas) y la corrección de estos errores (por atletas o pacientes) dependen fundamentalmente de diferentes sistemas de percepción que pueden diferir en su sensibilidad, unidad de control y capacidad de entrenamiento.

Comparing Video Analysis to Computerized Detection of Limb Position for the Diagnosis of Movement Control during Back Squat Exercise with Overload

“…On the other hand, evaluators performing visual observation of the performance might perceive (and evaluate) this variation in back squat execution as incorrect due to the lack of an appropriate reference or even perceive small functional motion variability as disarrangements [ 62 , 63 ]. To avoid additional sources of misinterpretation in the analysis of the movement by evaluators, the current study recruited a single group of experienced male lifters, but even in this category of participants (i.e., advanced), there are qualitative motor differences during the execution [ 33 , 73 ] that might contribute to the disagreement of judgement between evaluators. Finally, future research should focus on analysing subjects’ movements in three dimensions rather than just in the sagittal plane.…”

Managing the cognitive loads associated with judgment and decision-making in a group of adventure sports coaches: a mixed-method investigation

“…Profiling performers is not new and, unsurprisingly, the coaches employed a range of observation and questioning strategies (Giblin, Farrow, Ball, & Abernethey, 2015). These appear highly individualised, both towards the performer and coach (McGarry, 2009) with coaches having preferred approaches, questions and assumptions based on their experiences and forming a set of highly personal heuristics built within the absolutes mentioned earlier.…”

A qualitative study exploring tactical performance determinants from the perspective of three Rugby World Cup coaches

“…Expert coaches have the ability to recognise relevant patterns faster and with more accuracy than novices. 15,16 This pattern recognition derived from an extensive foundation of highly specialised declarative and procedural knowledge, makes them a valuable knowledge source. 16 Understanding the informational constraints that regulate goal-directed behaviour in rugby by using rich descriptions from experiential knowledge sources will support an explanation of performance.…”
