Triplanar movements develop rotary and angular/diagonal strength to assist the prime movers. More important, prime movers can act with rotary and angular/diagonal strength, though most people fail to develop this capacity! Developing multiplanar strength of the prime movers increases stability, enhances injury prevention, multiplies force production abilities, and, most important, stimulates the neuromuscular patterns required of athletes.
Prasara yoga, by its movement through the six mechanical degrees offreedom, targets the rotary and angular/diagonal strength to develop these motor recruitment patterns so that we become simultaneously strong and functional. Without this, our performance suffers greatly and injury likelihood significantly increases.
The term six degrees of freedom refers to motion in three dimensional space, namely the ability to move forward/backward, up/down, left/right (translation: in three perpendicular axes), combined with rotation about three perpendicular axes (yaw, pitch, roll). Because the motion within these three axes combines with the rotation about the three axes, movement gains infinite degrees of freedom. There is no limit to the variations. The motion indeed has six degrees of freedom.
