300718 Building Athletic Movement-part 2
Physical athleticism requires precise mastery and powerful execution of specific sport movement/motor system patterns. In order to accomplish these multifaceted demands on the body each of the interacting sequential muscle groups within the kinematic chain and kinematic system have to be functioning and producing their peak tension at the exact right time.
Each exercise or sport movement is formed by and evolves from a cause and effect relationship with the individual elements making up the pattern. The line of force which is developed to successfully complete these movements depends on the efficiency of the neuromuscular system. The relationship between these mechanisms is constantly changing in an effort to find the most balanced response to the required movement pattern. Meanwhile additions to the dynamic element are being added to the equation.
This latter represents the ‘rigid framework’ i.e. the determination of the spatial time parameters and the working effect of the movement. It is this dynamic concept that is vitally important to the athlete and their coach.
The dynamics of the patterns depend on the interaction with the sport implement; in the case of the lifter, the loaded barbell of dumbbell. This interaction is further divided into concentration and the dynamic reaction to the load.
Expanding on this interactive process leads one to the conclusion that we are not just discussing the physical expressions of the movement but also the process that evolves during the active accentuation of the motor unit’s responses to the external stimuli, i.e. the load.
