  In this paper, for the first time, there is comprehensively tackling the
problem of biomechanical optimization of a sport of situation such as judo.
Starting from the optimization of more simple sports, optimization of this kind
of complex sports is grounded on a general physics tool such as the analysis of
variation. The objective function is divided for static and dynamic situation
of Athletes couple, and it is proposed also a sort of dynamic programming
problem Strategic Optimization. A dynamic programming problem is an
optimization problem in which decisions have to be taken sequentially over
several time periods linked in some fashion.
  A strategy for a dynamic programming problem is just a contingency plan, a
plan that specifies what is to be done at each stage as a function of all that
has transpired up to that point. It is possible to demonstrate, under some
conditions, that a Markovian optimal strategy is an optimal strategy for the
dynamic programming problem under examination. At last we try to approach the
optimization of couple of athletes motion. Shifting s Trajectories study is a
very hard and complex work, because falls among fractal, self similar
trajectories produced by Chaotic, irregular, Dynamics. It is possible to
Optimize Athletes motion planning. Motion planning could be defined as the
problem of finding a collision free trajectory from the start configuration to
the goal configuration. It is possible to treat motion as an optimization
problem, to search the trajectory that drive adversary into a final broken
symmetry position, where it is possible to collide and apply one of the two
throwing tools: Couple or Lever.
