The growing interest in running as an exercise, and particularly as a sport of competition, demands the study of runner's metabolic efficiency. The estimate of the critical velocity (CV) has been used in different studies to since it is a method of simple applicability to determine the anaerobic threshold of runners, taking into consideration the intensity of effort and the execution time. The objective of the present work was to identify and compare the efficiency of methods that are currently being used for the estimation of runner's CV. A bibliographic review of scientific articles published during the period 2011 to 2016 was carried out. The analysis of the literature showed the estimation of CV is determined by different strategies such as: maximal and submaximal tests, continuous and intermittent, in athletics track, tradmill and asphalt; with different groups of runners. The determination of critical velocity enabled an efficient establishment of the anaerobic threshold of runners, regardless of the group of individuals analyzed in a simpler, less costly, and equally reliable as other more sophisticated methods of anaerobic threshold estimation that require laboratory tests.

Keywords : critical velocity; critical power; anaerobic threshold; runners.
