**2. Methods**

This research had a descriptive characteristic [13] which verified the anthropometric profile and cognitive performance among elite and non-elite athletes of the beach volleyball modality. The universe of the study was constituted by athletes of the national circuit of beach volleyball/Banco do Brazil and the Cabo Branco Beach Volleyball Training Center/CT Cangaço. The sample was composed by 8 athletes, selected by non-probabilistic procedure, of the intentional type, with age bracket between 18 and 35 years old, being 04 elite athletes and 04 non-elite athletes. The participants received an informative document with all the procedures performed in the research. Afterwards, an informative document containing all the details regarding the date, time and place of research was delivered. Athletes who did not present the Free and Informed Consent Term - TCLE; did not agree with the terms of commitment, assumed with the researcher; were under medication treatment that influenced the execution of the tests; those who refused to participate in the study as volunteers, with no return or financial advantage, and those who did not show up on the day of data collection, were excluded from the process. The present study complied with the norms for research with human beings, resolution 466/12 of the National Health Council. CAAE: 26950119.0.0000.5176. One of the CogState® Computerized Cognitive Test Battery (Brief Battery) was used in the evaluation of cognitive performance, which is composed of four tests: Detection Test (cognitive domain measured: Psychomotor Function) **Figure 1**, Identification Test (cognitive domain measured: Attention) **Figure 2**, One Card Learning Test (cognitive domain measured: Visual Learning), One Back Speed Test (cognitive domain measured: Working Memory) in the study conducted used 4 tests from the (Brief Battery/ Brief Battery) being they Detection (Simple Reaction Time); Identification (Choice Reaction Time); One Back Speed (Working Memory); One Back Acuracy (Short Term Memory) which presented results in milliseconds (ms) and logarithmic values normalized to base 10, with validity from 0.76 to 0.89 [14, 15]. It was necessary to perform a demonstration of the protocol to facilitate the understanding and learning of the test. The analysis was done by the quantitative number of positive and negative answers divided by the total number of attempts executed.

Such results will be presented as percentage of correct answers. For weight evaluation a Tanita® Bc 601 bioimpedance scale was used, the individual barefoot with legs slightly apart with arms at the side of the body with the most erect body possible. For height assessment, a *Standard Sanny®* - ES 2030 stadiometer was used, with a range of use of 0.80 to 2.20 m, resolution in millimeters and a tolerance of +/− 2 mm at 2.20 m. The individual was barefoot, with heels together and arms relaxed. The data were classified as non-parametric with the analysis of the dispersion curve performed by the Shapiro Wilk test. The variables of anthropometric profile and cognitive performance were compared with the *Mann Whitney* U test between the two groups. The procedures were performed with a significance level of *p < 0.05 using* the Statistical Package for the Social Science - SPSS®, Version 25.0.
