AVALIAÇÃO DO CONSUMO DE OXIGêNIO (VO2máx.) EM TESTE DE BANCO: UM ESTUDO LONGITUDINAL EM ALUNOS DO NUCLEO PREPARATóRIO DE OFICIAIS DA RESERVA (NPOR) LOTADOS NO 16º REGIMENTO DE CAVALARIA MECANIZADA (RECMEC)

The aim of this study is to measure the VO2max in ascent and descent bench test in three moments, during the officials' of the reservation preparatory course. Methodology: it's an applied research, longitudinal, analytical, and probabilistic. The sample consisted of 15 active men, average of age 18,07±0,5 years old. The stature was measured (m), body mass (kg), heart frequency of effort (HFE) it was controlled the phases, increment of the height of the bench (cm), number of touches per minute (t/m) ascent and descent rhythm of the ergometric bench and time of execution. The individuals used a cardiofrequencimeter of the Polar mark A5 in the gauging of CF and the Table of Borg in the subjective control of the effort. The ergometric test applied was the Test of electronic bench of Cirilo (TEBC) in three different moments (3 months of interval): AVL 01, AVL 02 and AVL 03 of the year 2005. The used statistics was descriptive of average, deviation-pattern, maximum and minimum and inferential through the test of Friedman for repeated measures. The significance level was p <0,05, the software SPSS version 10.0 was used. Results: first, it was obtained an average of VO2max of 38,34±1,68 ml/kg/min, in the second 38,34±0,68 ml/kg/min and in the third 37,96±1,74 ml/kg/min, having significant differences just in the third moment (p=0,005) with decrease of the performance. Conclusion: The level of capacity cardiorespiratory was classified in reasonable in the 3 moments of test for the index of VO2max, with decrease in the third moment, and it was not characterized a satisfactory way for the specific needs of the troop during the investigated period, if compared the levels of this capacity with other studies in military. New studies are recommended, trying to evaluate the volunteers in different phases of the physical and tactical training, for more accurate analyses of the impact of the program.
