Abstract

The aim of this study was to
determine the effects of aerobic training on biomechanical parameters and
lactate response (La) during sprint swimming test (SST) and evaluate their
relations with the progress of swimming time in adolescent swimmers.

Twenty-eight swimmers (15 males
and 13 females aged 13-16 years) performed an all-out 100-m sprint swimming
test twice pre and post 12 weeks of aerobic training. Basic
anthropometrical measurements including body height, body weight, body fat
percentage and physiological and biomechanical parameters in SST were obtained
and such measurements repeated after 12-week training period. Video analysis
determined the stroke count, stroke rate, stroke length, split time, swimming
speed during 100m-sprint swimming test. Heart rates and blood samples for La
were taken from the fingertip pre exercise and at the fifth minute of recovery.
Results were processed with SPSS 20.0.

The results showed that the swimming
time and stroke count decreased and stroke length, stroke rate and La levels
increased significantly (P<.05 for all). No significant changes was seen in
antropometry. Swimming time was correlated with both biomechanical parameters
and La response. La was also correlated with stroke rate and swimming speed.

In conclusion instead of
excessive training loads, just aerobic training may remarkably contributes to
sprint swimming performance in adolescent swimmers.
