Introduction and methodology:<\/strong><\/p>\n Muscular force production while stroking is determinant in competitive swimming performance (Keskinen, Tilli, & Komi, 1989). As a consequence of this fact, some authors have sought a relationship between swimming performance and multi-joint dry-land exercises involving the same muscle system required in swimming (Morou\u00e7o et al., 2011; Perez-olea, Valenzuela, Aponte, & Izquierdo, 2018). However, the environmental conditions of these exercises are different from those experienced by swimmers in the water (Rav\u00e9 et al., 2018). Hence, tethered swimming was one of the methodologies used to the measurement of force, being stated as a valid and reliable methodology to assess swimmer\u2019s strength potential (Akis & Orcan, 2004; Amaro, Marinho, Batalha, Marques, & Morou\u00e7o, 2014). During tethered swimming the force is measured through a transducer fixed to the wall and connected to swimmers\u2019 hip by a non-elastic.<\/p>\n The aquatic environment complicates the direct measurement of force application (Akis & Orcan, 2004), resulting in kinematical differences between free-swimming and tethered swimming (Samson, Monnet, Bernard, Lacouture, & David, 2018). These differences are due to the stationary water and the nondisplacement of the swimmers. Hence,\u00a0 the use of a flume was indicated as a way to replicate the conditions experienced during free-swimming (Vorontsov, Popov, Binevsky, & Dyrko, 2006). Thus, in our Aquatics Lab, we studied the relationship between tethered swimming in a flume and free-swimming performance. We found stronger relationships between tethered force parameters and swimming performance as the water flow velocity increased (Ruiz-Navarro, Morou\u00e7o, & Arellano, 2020). The fact that the relationship between tethered force parameters and swimming velocity increased as the water flow approached the actual free-swimming velocity seemed to evaluate the ability to apply force in the water. Meanwhile, at zero velocity it appeared to measure the muscle strength potential of the swimmer (Ruiz-Navarro et al., 2020; Vorontsov et al., 2006).<\/p>\n <\/p>\n <\/p>\n Unfortunately, not many clubs can afford the cost of a swimming flume, so other options have been considered. Semi-tethered swimming became an alternative, as it allows swimmers\u00b4 displacement while force production is registered. In addition, the 25 m swim speed was shown to be strongly correlated with maximum swim power (Dominguez-Castells, Izquierdo, & Arellano, 2013). Furthermore, semi-tethered swimming has been used as a method for power-strength in-water development through the use of power-racks, elastic cords, or parachutes. Nevertheless, when implementing these methods, high loads alter the kinematics of swimming (Cuenca-Fern\u00e1ndez, Gay, Ruiz-Navarro, & Arellano, 2020), which produces a deterioration in swimming patterns that might be counterproductive and result in a worsening of swimming performance (Francisco Cuenca-Fern\u00e1ndez, Ruiz-Navarro, & Arellano, 2020).<\/p>\n <\/p>\n Applications for coaches<\/strong><\/p>\n Tethered swimming is a useful tool for swimming assessment and training. The use of a flume allows overcoming the differences between free-swimming and tethered swimming, evaluating the ability to apply force in the water. Subsequently, semi-tethered swimming can be also used as an alternative to tethered swimming. This methodology is often used in daily training for in-water strength and power development. However, coaches shall be cautious about applying high loads, as it can alter the swimming kinematics. Therefore, swimmers should focus on the strength and power development with the proper technique (i.e., the same technique as they will use while free-swimming).<\/p>\n <\/p>\n Original version of the study<\/strong><\/p>\n Ruiz-Navarro, J.
