English abstract
The study aimed to examine the relationship between the muscular capacity of the lower limb for the individual when belonging to the prepuberty 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, Standing long Jump, Triple Jump, Five Jump (SUT, TJT, FJT) and tests the speed in a one-line (SOL) twice 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. Also this study find out that the muscle strength index of the lower limbs of the five jumps test (PIFJT) Predicts 51% (p = 0.000) of the total time recorded in the speed test for the pre-peak height velocity group. For the post-peak velocity group, the study found the five jumps test (FJT) with the standing Long Jump Test (SUT) predicts 56% (p = 0.031) of the total time recorded for the speed test in a straight line.
Key words: Horizontal Jump, Five Jump Test, Triple Jump Test, Standing long Jump Test, speed one line, growing stages
