Resumo

Introdução: o desempenho na natação pode ser influenciado por diferentes fatores, como a técnica de nado, as forças envolvidas na tarefa ou, ainda, aspectos fisiológicos e biomecânicos, dentre estes as análises das forças propulsiva (FP) e resistivas (FR) são de fundamental importância para o desenvolvimento da natação competitiva. O nado amarrado é um método largamente utilizado por técnicos pesquisadores nos últimos 50 anos, podemos atribuir isso a sua praticidade e custo reduzido quando comparado a outros métodos. Objetivo: elucidar a aplicabilidade do nado amarrado em nível histórico e prático. Método: foi realizado um levantamento bibliográfico em bases de dados cujos trabalhos utilizaram de alguma forma o nado amarrado ou que o estudaram. Resultados: foi observado que o nado amarrado é uma ferramenta com alta reprodutibilidade, possui boa relação com o desempenho na natação e pode ser utilizada para o acompanhamento de atletas ao longo de um programa de treino, bem como servir de potencial preditor de talentos esportivos. Conclusão: o nado amarrado possui lacunas quando a descrição detalhada dos métodos utilizados, contudo devido ao volume de trabalhos produzidos nas últimas décadas, podemos afirmar que este possui base sólida para ser aplicado para pesquisas e treinamento de natação.

ABSTRACT. Tethered swim: a historical review and applicability. Background: swimming performance can be influenced by different factors, such as swimming technique, the forces involved in the task or, also, physiological and biomechanical aspects, among which the analyzes of the propulsive (PF) and resistive (FR) forces are of fundamental importance for the development of competitive swimming. The tied swim is a method widely used by technical researchers in the last 50 years, we can attribute this to its practicality and reduced cost when compared to other methods. Objective: to elucidate the applicability of the tied swim in historical and practical level. Methods: a bibliographic survey was carried out in databases whose works somehow used the tethered swimming or studied it. Results: It has been observed that the tied swim is a tool with high reproducibility, has a good relationship with swimming performance and can be used to accompany athletes throughout a training program, as well as to serve as a potential predictor of sports talents. Conclusion: the tied swim has gaps when the detailed description of the methods used, however due to the volume of work produced in the last decades, we can affirm that it has a solid base to be applied for research and swimming training.
