Summary

Nasal patency is an important component of performing exercises because it helps in humidifying, heating and filtering the inhaled air. However, many athletes and exercisers experience difficulty breathing through their nose, which can affect their breathing and performance. Namely, during sports activities and greater physical effort, there is increased air flow, which causes significant dehydration and cooling of the mucous membrane of the upper respiratory system. This dehydration is associated with the release of inflammatory mediators, which can ultimately lead to narrowing of the airways (eg in athletes with asthma). However, in all athletes, regardless of whether they have asthma or not, damage to the airways can occur because during exercise, hyperpnea exposes the respiratory epithelium to increased physical forces and pressure, which leads to the risk of exfoliation of the previously dehydrated epithelial cells of the nose and even their complete separation. Repeated stretching and compression can negatively affect the functionality of the epithelium and, with repeated exposure and damage, lead to structural and functional changes.

Rinsing the nose with a hypertonic or isotonic solution of seawater is a potential solution for nasal obstruction because after rinsing, the airflow through the nose improves and symptoms of obstruction are reduced. However, the effects of using nasal lavage solutions along with exercise in elite athletes are not yet known. The potential synergy of exercise and isotonic seawater solution as a nasal spray on airflow and the subjective impression of nasal patency in healthy individuals has not been sufficiently investigated5.

Research question

What is the effect of an isotonic seawater solution applied as a nasal spray on nasal airflow and the subjective impression of nasal obstruction in healthy athletes?

Hypothesis

An isotonic seawater solution applied as a nasal spray will improve nasal airflow and the subjective impression of nasal obstruction in healthy athletes.
