علاقة القدرة العضلية للأطراف السفلى مع أداء السرعة في خط مستقيم وفقا لمراحل النمو

Abstract EN

The study aimed to the examine the relationship between the muscular capacity of the lower limb for the individual when belonging to the pre- puberty and post.

through the horizontal jump tests for the youth ages (13 ± 2) years and determine which jump tests can predict performance in repeated speed one-line (SOL).

to achieve this, the study was conducted on a sample of 107 individual (age : 12.59 ± 1.46, length : 1.49 ± 0.08, weight : 47.83 ± 15.59).

all the individuals performed the following tests: horizontal jump tests and speed in a one-line to verify the stability of the tests and then apply the test protocol.

one of the most important findings of this study is that all applied tests have relation with speed of two groups, either the pre-puberty and post.

this study also showed that plyometric training programs based on horizontal jumping, especially the five-jump test can improve the sprint in a straight line in the group belonging to the stage before reaching peak height velocity (PHV), and relying on the exercises of the five-horizontal jump and the broad jump to improve the sprint in a straight line for the stage after reaching PHV.
