The four movement phases are the stance phase, preparatory phase,

Movement phases are movement therapy consisting of the assessment of the quality of a movement relating to a particular point.  This happens with the intent of optimizing efficiency movement ease within a specific timeline. Movement phases are illustrated below.

The stance phase is gait phase which controls 60% of a single cycle. It last from heel strike to toe-off. The foot acts as the shock absorber, rigid lever, pedestal and mobile adapter when placed in the ground in this phase and the other foot Pass over its top (Swanson, 2007). During this phase, the knees are at their flexion. In runners gait, the hip, ankle, knee are in extra flexion compared to the heel strike in stance phase. As your body moves frontwards the knees and angle allow optimum energy absorption through the lower extremity.

Preparation phases are a phase that facilitates the impending movement. Example when jumping one need to bend at your hips, ankles, and knees.when using your hand preparation phase happens by liberating movement frees hands from a constrained position such as the position underneath another hand resting position. It helps to facilitate speed, the efficiency of the task and strength (Gallego,2010) .

Movement phase. During this period elements of the amphibious force change points of embarkation to the effective area. The move can happen via rendezvous, staging and rehearsal areas. The phase is competed by elements of amphibious force arriving at their suggested operational areas (Shamaei, 2013). Follow through the phase is the phase that prevents and slow the body’s movement to avoid injury as one get ready to come up with other movement or both. The body rebalances and stops the forward motion and muscles activity return to resting level. From the above characteristics of every movement phases, it is clear that each influence the efficiency of the other phase. If one phase is incorrect, then there is no movement because the next phase will not happen.
