Maximal accumulated oxygen deficit determination using the backward extrapolation technique in swimmers, runners and cyclists

Abstract

In order to optimize the anaerobic capacity evaluation, the main aim of the present project is to validate the evaluation of the maximal accumulated oxygen deficit (MAOD) and reduced MAOD using the backward extrapolation technique (MAODextr and MAODREDextr). Forty-five athletes (15 swimmers, 15 runners and 15 cyclists) will be submitted to three phases. In the first phase, the subjects will perform a 300-s all out front crawl swimming trial. Based on the 300-s swimming velocity, subjects will perform efforts between 15 and 120s with increments of 15s, and efforts between 120 and 270s with increments of 30s in three different days. The oxygen uptake (VO2) of these efforts will be measured by the backward extrapolation technique and the VO2 kinetics in swimming using the conventional method (CM). The data about VO2 versus time will be plotted and analyzed using the bi-exponential or mono-exponential function. In the fourth day, athletes will perform a 300-s maximum effort front crawl swimming trial using the VO2 analyzer. The aim of this first phase is to measure the VO2 kinetics in swimming using the backward extrapolation technique. In the second phase, the MAOD will be determined by the difference between the predicted VO2 and measured VO2 using the CM during the 300-s all out. In addition, using the VO2 data measured by CM after the 300-s all out, the MAODRED will be determined by the analysis of the contribution of alactic and lactic anaerobic metabolism. In the third phase, the MAODextr and MAODREDextr will be determined as mentioned in the second phase; however, the VO2 during the first phase will be analyzed using the backward extrapolation technique. In order to validate the MAODREDextr e MAODextr, the Pearson product-moment correlation, the Student's t test and the analysis of Bland and Altman will be used. All statistical analyses will be set at 5%. (AU)
