Résumé:
The study aimed to identify the effect of a proposed training program
using high-intensity interval training (HIIT) on the development of maximal
aerobic speed (MAS) and maximal oxygen consumption (VO₂max) among under19 football players. To achieve this experimentally, the researcher adopted the
experimental method using a two-group design (experimental and control) with
pre- and post-measurements. The study sample consisted of 18 under-19 football
players who were purposefully selected and evenly divided into two groups: 9
players in the experimental group and 9 in the control group.
As for the study tools, the researcher used the Vameval test to measure
maximal aerobic speed and a treadmill test to assess maximal oxygen consumption,
in addition to implementing the proposed training program designed by the
researcher.
The results revealed statistically significant differences at the 0.05 significance
level between the pre- and post-tests in both the MAS and VO₂max tests in favor
of the post-test for the experimental group. Furthermore, the researcher found
statistically significant differences between the experimental and control groups in
both variables, in favor of the experimental group subjected to the high-intensity
interval training.
In light of these findings, the researcher recommends the adoption of this
training method and the use of the proposed program to improve maximal aerobic
speed and maximal oxygen consumption in under-19 football players
