Résumé:
The study aimed to know the effect of interval training on the indicators of
aerobic capacity, and knowing the existence of variances between the change
parentages of these capabilities after the training, as that the researcher supposed
that there are variances with statistical significance between pre and post
measurement in aerobic capabilities after interval training, and according to the
nature of the research that depends on experimental method, it has been chosen a
sample research non randomly which include twenty four players from the team
of Widad Mostaganem under the age of nineteen that they underwent to the
training program with interval method for eight weeks which contains three
quotas in the week, while the pre and post tests have conducted in order to
measure their capabilities aerobic, as the results showed the existence of
variances with statistical significance between pre and post measurement for the
research sample and in favor of post-test, as that they showed the existence of
variances with statistical significance between the change parentages of aerobic
capabilities for maximum aerobic speed and anaerobic threshold.So we conclude
that the interval training improved aerobic capabilities by increasing the
(VO2MAX, VAM,AT and FCMAX )and the greatest influence be into the anaerobic
threshold(AT) and the maximal aerobic speed(MAS) .
Key Words: interval training, Maximum oxygen uptake, maximal aerobic
speed, aerobic threshold
