ABSTRACT
Purpose:
The aim of the study was to assess lactate and glucose concentrations as indicators of anaerobic capacity in a highlyranked female junior swimmer.
Methods:
Ten trials of a 5 × 200 m backstroke step test were performed between December 2008 and July 2011. Each trial was video-recorded and blood samples were drawn from the ear lobe 1 min after completion of each step to measure lactate and glucose concentrations.
Results:
During maximal effort, lactate concentrations of 5.1 to 13.1 mmol • l-1 were recorded, while glucose concentration varied from 6.6 to 8.1 mmol • l-1. Correlations between lactate and glucose concentrations were significant in most tests. The shape of lactate and glucose curves revealed an improvement in the swimmer’s endurance ability during subsequent tests.
Conclusions:
Analysis of fluctuations in lactate and glucose concentrations appears to be a relevant indicator of the anaerobic capacity of experienced swimmers.
