Résumé:
The research aims to know the effect of implying plyometric method to improve the upgrading capacity and the
digital achievement in the effectiveness of the long jump. Where researchers used the experimental method to the nature of
research, and the sample consisted of high school students of Relizane province (Algeria). The 56 students were selected and
divided into two groups in equal number, while the tests used were the broad jump test of the stability, vertical jump, and
digital test achievement in the long jump. After statistical processing of the raw results, the researchers concluded that the use
plyometric method in physical education and sports classes for high school students has improved the upgrading capacity, as
well as digital achievement in the long jump, in addition to the superiority of the experimental sample over the control sample
in the test results. The research finding confirms the effectiveness of using plyometric exercises with students while teaching in
improving the digital achievement with the experimental research sample.
