The main objective of the study was to evaluate the cardiorespiratory ability of football players of five-a-side football. Secondarily we sought to assess the validity of an indirect method for the estimation for cardiorespiratory ability in this population group. Methods: A sectional study involving 8 five-a-side football players was realized (Football-5; median age=26 minimum=17 and maximum=30 years) and 7 futsal or football society seers players (Football-5; median age=25 minimum=20 and maximum=33 years). The cardiorespiratory ability was measured and evaluated through the completion of cardiopulmonary exercise testing (TCE), on treadmill, with the ramp protocol. The estimation of the cardiorespiratory ability was done by conducting the test Shuttle Run of 20-m.The intergroup comparisons was conducted through the test Mann-Whitney and intergroups was through the test Wilcoxon, both with simulation of Monte Carlo (α=5%). The Shuttle Run 20-m validity was checked by the intraclass correlation coefficient (CCI) and the Altman and Bland approach (SPSS 13.0 for Windows and Microsoft Office Excel 2007). Results: On TCE, the five-a-side football players showed lower uptake of oxygen (VO2) of peak, total effort time, speed at the end of the test, and these differences are statistically significant. Similarly, in the Shuttle Run of 20-m test the players showed worse performance, with a lower speed values achieved at the end of the test, distance and VO2 estimated. As test Shuttle Run 20-m validity, the players showed higher median values of VO2 in TCE (measured) relative to the Shuttle Run of 20-m (estimated) (p<0,05). Despite the differences between the methods are within the limits, calculated in the approach of Altman and Bland, players showed systematically higher values in TCE. The CCI demonstrated a moderate validity between methods. Conclusion: The five-a-side football players showed lower cardiorespiratory ability to athletes seers football either by TCE or Shuttle Run of 20-m. The Shuttle Run of 20-m test did not appear as a valid method for estimating oxygen uptake in this population group.application/pdfopenAccesshttp://creativecommons.org/licenses/by-nc-nd/4.0/deficiência visualfutebolconsumo de oxigênioFisioterapia e Terapia OcupacionalDissertação
