RESUMO

Football players physical evaluation are important with regards to offering more precise parameters to a training programme. This way, the aerobe capacity has been shown into an important variable in the training context, and there is some worry to approximate the evaluation of this variable within the specificity in which it is used. This work is characterized as a descriptive research and had the objective to validate a field test to evaluate de VOz max of f_otball players. Eleven - athletes hav:.. been evaluated in- this study (age: - X=16,1 +0,52); (height: X=173,31cm X + 7,34cm);(weight X=66,53kg);fat% ( X=12,53+5,34). I t has been used two tests, the former, a continuous laboratory test already validated with 7 km/h initial speed with speed increment (1.2 km/h) every minute until exhaustion. The second test occurred on a two hundred thirty (230) meters circuit of a football field, with motor activities similar to those used by players during a football match, with 6km/h initial speed, with weight increment (2 km/h) every circuit round until exhaustion, without interruption. The people were submitted to a second test a week later in the field test, in order to verify the reproducibility of the proposed testo It has been used the K4b2 equipment to evaluate the VOzmax. It has been also checked the existence of the VOz plateau and the secondary criteria; the coefficient of respiratory changes (R), heart frequency and the concentration of blood lactate in the fmal testo The plateau, the R and FCM were obtained through the equipment software used in this research (K4b2), while the blood lactato analysis was done by using and electrochemical analyzer YSL 1500 ST A T Yellow Spring. As statistic procedure, it has been used the descriptive one, Pearson s correlation and interclass correlation and still "t" test of Student. The field test was validated and the results pointed to the non difference existence between the results from the laboratory and field test
