seggy interaction Flashcards
Segmental interaction principle
states that forces acting between the segments of a body can transfer energy and momentum between segment
5 principles of seg interaction
# of segments Order of segments Max velocity Stabalise Follow through
of segments
Use as many segments as possible
order of segments
Use largest/slower segments first and smallest/fastest segments last
Max velocity
Each segment should reach max velocity before next segment begins to contract/move
Stabalise
Each segment should stables before the next segment commence movement
Follow through
use a follow through to ensure there is no deceleration of the final segment
Kinetics
examines and describes the forces needed to produce movement
Kinematics
Examines and describes the movement patterns needed to produce efficient movement
Kinematic chains
Is the process of identifying how best to use segments of movement for power or accuracy
Kinematic coordination of movements
can be pictured as a continuum, ranging from simultaneous body segment actions to sequential actions
Kinematic chain when accuracy is the primary concern
generally involves less segments and they are used simultaneously
Kinematic chain when velocity and distance is primary concern
involves more segments and they are used sequentially
