Nado amarrado: uma revisão histórica e sua aplicabilidade.

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.
