Estimating sports performance is essential for the characterization, adjustment and monitoring of athletic training. Each tactical position has a value and this can be achieved by applying the most appropriate training. OBJECTIVE: To describe the sports performance values of athletes from Mato Grosso soccer. METHODS: The maximum oxygen consumption (VO2 max) was used to estimate the performance of the 20m shuttle run test and the Runing-based Anaerobic Sprint Test (RAST) for anaerobic power. The sample was intentional non-probabilistic, with 150 soccer players of the C and D male classes, who operated in Mato Grosso in the period between 2013 and 2015, stratified by category (basic and main categories) and by tactical position (striker, goalkeeper, side, sock, midfielder and defender). RESULTS: VO2max values were below the references for all categories and tactical positions. Base categories (in ml.kg-1 .min-1 ): attackers 45.79 (± 4.78), goalkeepers 44.42 (± 4.73), lateral 46.93 (± 1.6), middle 44 , 12 (± 3.92), flyers 46.14 (± 1.99) and quarterbacks 44.73 (± 5.6). Main category (in ml.kg-1 .min-1 ): attackers 45.28 (± 4.92), goalkeepers 44.59 (± 3.00), side 43.65 (± 6.81), middle 43 , 43 (± 7.09), leaflets 44.59 (± 6.09) and quarterbacks 45.49 (± 4.9). At maximum anaerobic power (P max) values below the reference for all categories and tactical positions were found. Base categories (W.kg-1 ): attackers 8.46 (± 0.95), goalkeepers 8.38 (± 0.99), side 8.04 (± 1.02), socks 7.84 (± 1.63), leaflets 8.33 (± 0.19) and quarterbacks 8.9 (± 1.49). Main (W.kg-1 ): attackers 8.15 (± 0.79), goalkeepers 9.29 (± 1.24), lateral 8.72 (± 1.06), half 8.45 (± 1, 32), flyers 8.7 (± 0.94) and quarterbacks 9.11 (± 0.83). Comparison (test T level of significance 0.05) of VO2 max and anaerobic power of the categories, results: VO2 max, p=0,309, P max p=0,045, P méd p=0,134, IFW.s-1 p=0,001 e IF%, and p=0,270, indicating that there was a significant difference between the two groups in P max and in IFW.s-1 . VO2 max, p = 0.703, P max p = 0.873, P med p = 0.175, P min p = 0.757, IFW.s-1 p = 0.739 and IF%, and p = 0.341, indicating that there was no significant difference between them. VO2 max, p = 0.941, P max p = 0.237, P med p = 0.800, P min p = 0.124, IFW.s-1 p = 0.104 and IF%, p = 0.066, indicating that there was no significant difference between them. The maximum velocities in 35 m were 23.84 (± 1.00) km.h-1 basis and 24.21 (± 1.00) km.h-1 main. There was no statistically significant difference between the velocity of the positions at both the base (p = 0.876) and the main (p = 0.221). CONCLUSION: The analysis of VO2 max, anaerobic power and velocity contradict studies that indicate differences between the tactical positions, which added to a generalized low performance of these valences suggests inadequacy and lack of specificity for position in the training of these athletes.
