Abstract
The aim of this study was to determine the effect of several months of training on
performance and energetic profile of elite swimmers. 9 elite swimmers were evaluated
at 3 different time periods during the 2010–2011 calendar. Swimming performance was
assessed based on lists of times for the 200 m freestyle event. An incremental set
of 7×200 m swims was applied to obtain the energetic data. Measurements and/or estimations
were made for the: velocity at 4 mmol l − 1 of lactate concentrations, highest value of lactate concentrations, maximal oxygen
consumption, minimum swimming velocity where the maximal oxygen consumption is reached
and total energy expenditure (Etot). The performance and most of the energetic variables assessed presented no significant
variations during the study period. The only exception was the Etot with significant differences between all measurements. Correlation coefficients suggested
a high stability for all variables. Cohen’s Kappa tracking index demonstrated high
variability in the individual adaptations to training. It is concluded that elite
swimmers demonstrate a slight improvement in performance and energetic profile in
response to several months of training. Each subject has an individual way of adapting
to the training load, combining the different energetic confounders to enhance performance.
