Why do some players appear slow, but at a crucial point they move incredibly fast?

 This is defined as a capability to control core muscles in the moment of movement. Strengthening and stabilizing the core is one of the main goals in order to change the direction on a sport ground quickly and impeccably.

 The stronger your core becomes, the more stable and stronger become your joints, spine, and pelvic muscles. This results in a more efficient fighting, agility, less injuries.  Strong and stable core gives power to upper and lower parts of the body.

In order to improve coordination, balance and neuromuscular functions, it is recommended to train on non-stable surface.
