ABSTRACT:
It is difficult to give the profound meaning and definition of plyometric training. Generally plyometric training consists of those exercises which produce, “an overload of isometric type muscles action which invokes the stretch reflex in muscles.” The term plyometric is derived from the Greek language,”Pleythyein” which means, ‘to increase’. Here ‘Plyo’ stands for more and ‘Metric’ stands for measure. Here the enhancement of explosive strength takes place as a result of rapid eccentric contractions through powerful muscular contraction. ‘Chu’ Defined plyometric as,’the exercises that combine the speed and strength ability to produce an explosive power’. Plyometric training was first introduce by,’Fredwilt’, in the year 1975. This training improves the relationship between maximum strength and explosive strength. It improves the tolerance of the muscles for increased strength loads. The maximum force that a muscle can develop is attained during a rapid eccentric contraction is a mechanism of plyometrics. When a concentric contraction occurs immediately following an eccentric contraction and a generated force within the muscles can be dramatically increased.
