A COMPARATIVE STUDY OF INTERVAL TRAINING EFFECTS ON THE INDICATORS OF THE AEROBIC CAPACITY OF FOOTBALL PLAYERS UNDER 19 YEARS OLD

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
