SSC consists of a rapid eccentric contraction followed immediately by a concentric one on the same muscle
group (Norman and Komi, 1979). SSC is involved in many daily and sport tasks such as gait, running, hoping and
jumping. Actually any movement that has a quick succession of eccentric and concentric contractions includes the
phenomenon of SSC. Furthermore, plyometric training uses multiple drills that are based on the function of the
SSC and consists a basic tool for strength and conditioning in order to improve jump height and explosiveness.
