RESUMO

In this study, objective to analyse the validity of the eletronic equipment in a tests batery of tecnical moviments of voleyball, in the attack zone. It treat of a decriptive research, transversal, quantitative of primary data. The sample was of 12 young men, in the band age of 14 to 17 years old, participants of clubs and sportive guilds. The studied variables was: calibration, frequency and speed of pulses, varion of the produced and detected pulses, deslocation speed, deslocation between the passage points during the route of the left sector, right and central, jumps (spikes and blocks), total distance roted in the running, ball speed in the spike. In the analitic plan were used the statistic pacakage SPSS version 8.0 with descriptive statistc of mean, Standard desviation, maximun and minimum; Excel streadsheet 7.0 version 98 to the calculus of the amplitude degree of the control map of the variables, based in the tests repetition in the verification of the reliability and reprodutibility; inferencial estatistic with Anova One Way test for repeated measurements, Wilcoxon, correlation coeficient "r" of Pearson and Sperman, Student "t" test , for independents samples, Intraclass correlation coeficient (ICC), with significance levei of 5%; intervals with 95% of confiance. The analise was made by graphics and tables. The results was analyseds inicialy at the instrument calibration. It wasn t found significants diferences between the high of the two jumps measurement (Ieft setor, right and central) (p = 0,606), neigther to the athlete rout (p = 0,577). The coeficients were high with correlation r=1,00 and Spearman=0,999, to the jumps high and r=0,998 e Spearman= 0,999, to the route, showing a linearity between the two processes of measurement. For the ICC, it was found values above of 0,61 for ali the sectors and the varianace analyse (ANOVA) didn t present significance in the variables passage, jumps, routed distance and average spees with values of p=0,115 a p=0,994 for the repeated measures of the evaluators A and B. All the measures intra-evaluator stayed into the high and low limits of control. It follows that between tha evaluators, the measurements presented reliability and reprodutibility favourable to the study validation in the left sector, central and right, with linearity between the two processes of measurement. The passages, the jumps, the total routed distance and the ball speed, even though analyseds in the same conditions, presented diferences in each sector, with satisfatory ICC, however the left sector ifind more associations and aceptable correlations. All the correlations are above of 0,90 and the ICC of 0,60, indicating that the validation process is pertinent
