Construção e validação de um teste percepto-cognitivo para atletas escolares

Abstract

Volleyball is characterized by being a sport with open motor skills, in other words, it is susceptible to be in an unstable environment, therefore, motor actions are likely to achieve high perceptual-cognitive demands during a game. The goal of this present study was to create and validate a perceptual-cognitive test for school athletes. The research was observational. The sample consisted of 19 female with the following characteristics: average age of 13.9 years (SD=±1.170), average body weight 53.80kg (±10.60), average height 1.61m (±0.046) and average BMI of 20.90 kg/m2) (±4.230). The variables looked into were the average reaction time associated to the performance in the test realized using the SwitchedOn smartphone application, the TQR (total quality recovery scale), Brums (Brunel mood scale) and PDS (pleasure and displeasure). Besides the addition of variables to characterize the sample (age, height, body weight and BMI). For the descriptive values data analysis, basic descriptive statistics were calculated using the average and standard deviation, to compare the data between the days it were applied non-generalized Linear Models such as ETA effect size (partial etasquared) and to verify the data reproducibility and reliability the Intraclass Correlation Index (ICC) were required. The results showed, with regard to mood, that there were significant differences associated to confusion and tension that the athletes found themselves in the amount of days. Regarding the category, the U15 athletes were more fatigued and more tense compared to the U17 athletes. Between the first and second day, reliability was moderate in the best attempt (ICC=0.617), and in the average of 3 attempts (ICC=0.715) and good in the average of the last 2 attempts (ICC=0.789). On the second to third day, the best attempt (ICC=0.646) was moderate and good for the average of 3 attempts (ICC=0.782) and average of the last 2 attempts (ICC=0.764). The average ICC demonstrated that it is as moderate for the best attempt (ICC=0.631) and average of 3 attempts (ICC=0.748) and good for the average of the last 2 attempts (ICC=0.776). The test was proved reliable and was capable of evaluate the perceptualcognitive, as well as, showed itself as a low cost practical tool to evaluate volleyball school athletes.
