A multi-disciplinary symposium, to be held at the Department of
Exercise and Sport Science, Alsager Campus, Manchester Metropolitan
University, UK, Monday 30 October 2000.

At various levels of analysis, variability in the movement system is
becoming increasingly significant to theoreticians and practitioners.
It is clear that a multidisciplinary perspective is needed to
interpret its role during goal-directed activity. What are the
implications of these theoretical developments? How do they help us to
understand the nature of brain processes, perceptual-motor
development, movement system dynamics, physiological system
adaptations, and their implications for biomechanical measurement and
practical interventions strategies such as coaching?

This one-day symposium, organised by the Department of Exercise and
Sport Science at Manchester Metropolitan University, brings together
world class experts in various sub-disciplines for the purposes of
discussing the concept of variability at different levels of the
movement system. The following sub-disciplines will form the backdrop
for the meeting:

_ Psychology
_ Movement Science
_ Nonlinear Dynamics
_ Coaching Pedagogy
_ Physiology
_ Biomechanics
_ Neurosciences
_ Perceptual-Motor Development

Proposed Organisation and Structure
The multidisciplinary meeting breaks down naturally into two parts. In
the morning, the focus will be on examining the role of constraints on
the movement system, and the implications for perception and action
and skill acquisition. Karl Newell will discuss recent advances in the
structure of movement variability and how these developments influence
our understanding of motor system function. Geert Savelsbergh will
propose the idea of perceptual degrees of freedom and examine evidence
for the concept in young children. Lieke Peper will discuss
variability in relation to the prospective control of interceptive
actions. Craig Handford will conclude the morning session by examining
the implications of recent advances in understanding variability for
models of learning and coaching in sport, using the volleyball serve
as a task vehicle.

After lunch, discussion of the role and implications of movement
system variability at different levels of analysis is undertaken from
a multidisciplinary viewpoint. Alberto Minetti will examine
characteristics of antagonist muscles in reducing variability at the
level of mechanical force production, and Carlo Reggiani will examine
current understanding of variability in contractile properties of
muscle using single fibre analysis. Walter Freeman will present a
neurodynamical approach to the study of self-organising brain
processes and Rolf Ingvaldsen will outline how individual differences
has been construed in major psychological frameworks including
Behaviourism, Freudian theory, Cognitive Science and Dynamical Systems
theory. The meeting will be completed with an open Round Table
discussion involving the audience.

It is proposed to make available video-tapes of each coherent half of
the symposium.
