Resumo
It is known that detraining leads to the loss of cardiorespiratory and neuromuscular systems adaptations, once acquired with physical training, including swimming. Although several studies have been investigated the effect of detraining, through a physiological concept, it have not yet been found in the literature a study that have investigated the effect of detraining in kinematic variables during swimming. Knowing that, this work was developed in order to verify the detraining effect on kinematic variables in front crawl stroke performance with different breathing patterns. For this, we used a methodology based on video analysis for kinematic variables (swim time, stroke velocity, stroke rate, stroke length and hand velocity) in different breathing patterns (no breathing, breathing to the preferred side, breathing to the non-preferred side and bilateral breathing) during front crawl stroke, before and after the detraining period. The data showed that, after five weeks of detraining the swim time was increased, the swim velocity and stroke rate was lower, except for bilateral breathing. Although, the stroke time was increased and stroke velocity was lower in no breathing pattern and breathing to the preferred side, on the other hand, the stroke length was increased just in breathing to the preferred side. Therefore, these findings indicate that there are adverse effects of detraining on kinematic variables related to swimming front crawl stroke perfomance with various breathing pattern
