Weekly frequency effect of AIT on the aerobic power of recently incorporated military on the Brazilian Army/A influencia da frequencia semanal do treinamento intervalado aerobico, previsto no manual C20-20, sobre a potencia aerobica de militares recem incorporados ao exercito Brasileiro

This study's goal has been to verify the weekly frequency effect of AIT on the aerobic power of recently incorporated military on the Brazilian Army. 80 military, from the 9 Armored Regiment of Cavalry, have participated of the study, all voluntary, masculine sex, age 18.13 years, body mass 67.39 kg and stature 1.73 m, residents in the city of Sao Gabriel. All participants have made a pre-test, which consisted of the 12 minute test. The group was divided randomly, in four study groups, of which three had carried through the AIT in the weekly three frequencies, two and one days and the other composed the group has controlled, that it did not carry through the activity. Pre-test results were: 2805 m; 2810 m; 2830 m; e 2805 m respectively. The AIT was executed for six weeks, with two volume overloads, made every other week. At the end, a post-test was made in similar conditions of the pre-test, which results test were: 3010 m; 3060 m; 3027.5 m; e 2815 m. Was observed that there was no effect difference among training frequencies of training groups (A, B and C) nor differences between those and group D. A meaningful difference has been identified between pre and post training, between all training group and D group (control group). The results analysis led to the conclusion that an efficient execution oh this training, for aerobic increase can be reached by a frequency of the least once week AIT, for the period analyzed. Key words: running, military, interval training, aerobic power, 12 minutes Cooper Test. O presente estudo teve por objetivo verificar o efeito da frequencia semanal do TIA sobre a potencia aerobica de militares recem incorporados ao exercito brasileiro.
