Abstract Resume

Introduction:The purpose of this study was analyze the relationship between perceived exertion (Hooper Scale), stress biomarkers (CK) and vertical jump in the performance of athletes of the Brazilian
Athletics Paralympic Team throughout the preparatory and competitive period. Methods: Were analyzed a total of 22 athletes with different types of disabilities, members of the
Brazilian national team paralympic athletics both genders. The study was longitudinal character, consists of 5 evaluation periods, 3 preparatory and 2 competitive. Were evaluated serum levels of
creatine kinase (CK), analysis of vertical jumps Squat Jump (SJ), and perception of effort by Hopper scale in order to evaluate  the adjustments caused by of training during the preparatory and
competitive period. Statistical analysis was performed using the statistical software SPSS 15.0, which was held the Shapiro-Wilk normality test and adopted the non-parametric Wilcoxon test for
non-normal samples, and the test Spearman correlation to verify the relationship between the variables. For the analysis of CK deltas was used a maximum of 120%. It was also adopted the value of P
<0.05 for significance. Results: The activity and serum CK concentrations showed an increase in the final stages of collection as compared with the early stages throughout the study
period as well as the variables Hooper scale, presenting a significant difference at various times. When compared CK values, only the initial sampling at each moment was possible to note a significant
difference between week of training and Taper 1 (0.01) between Taper 1 and 2 (0.05) Taper 1 and World Championship (0.02) and the Parapan American Games and World Championship (0.02), the evaluation
of the initial collections. And when compared to the final collections, significant difference between the week of training and Taper 1 (0.01), Week of Training and Taper 2 (0.02) and Week Training
and the World Games (0.00), plus significant difference also between the Parapan American Games and the World Championship (0.04), Taper 2 and World Games (0.00). When analyzed the difference between
the initial and final values (delta) of CK, it was possible to observe that only the Taper 1 showed values above the 120% limit stipulated as a reference value. When analyzed the vertical jump, SJ
showed significant differences (0.02) between the week of training and Taper 1. There was an inverse relationship between CK and SJ. There was an inverse relationship between CK and SJ, with
significant difference of 0.00 at all time points analyzed, and when CK values increased to values decreased SJ. Conclusion: It was observed that both the CK as the variables of
perceived exertion scale of Hooper had similar behavior over the analysis period, with elevation peak and decline in the next few moments. However, the vertical jump test presented an inverse
relationship with the other tests, showing a drop in revenue at times when the levels of CK and perceived exertion were high. Thus it is possible to conclude that by controlling the CK values and
effort perception tests, such as Hooper Scale, you can monitor the level of performance of athletes.
