To improve ease, find your rhythm, and better coordinate your freestyle swimming, it is essential to learn to breathe properly and synchronize your breath with your movements.

This recommendation is soundly validated by sports science. A quasi-experimental study conducted by Xu (2025) demonstrates that a controlled breathing rhythm (such as breathing every three arm cycles) significantly improves swimming speed while decreasing the perception of effort. Biomechanically, observational work conducted by Seifert et al. (2010) reveals that proper coordination of breath allows for the maintenance of optimal body alignment and minimizes water resistance. Conversely, poor breathing technique disrupts buoyancy and increases the effort required to move forward. Furthermore, a meta-analysis published on PMC (2024) confirms that optimizing the respiratory muscles helps prevent respiratory fatigue during swimming. The proposed technical training is therefore a key step toward swimming with fluidity and conserving energy.
