Effect of bathing in the thermal mineral water well on the performance and potential pain of athletes. Randomized, controlled, single-blind study.

In rowing sports, where the same series of movements are repeated thousands of times, the lower lumbar region is the most stressed part. Because of this, even training on an ergometer can cause numerous lower back problems, even among competitors. In addition, rowers use many muscle groups during their sport, for which the beneficial effect of thermal medicinal waters, affecting the entire musculoskeletal system, can be beneficial, and is used for rehabilitation purposes in several countries.

Studies describe the numerous positive effects of bathing in warm water (37-46°C) in increasing blood flow, regulating blood sugar, and even the positive response of the vascular system.

The Palatinus Spa's water supply is provided by the drilled thermal wells of Margit Island of Budapest.

Regarding its type, the medicinal water is a low salt concentration, calcium-magnesium-hydrogen carbonate, chloride, and sulfate medicinal water, which also has a significant fluoride and metasilicic acid content. The total dissolved mineral content is 1205 mg/liter. In the study, we would conduct the clinical trial necessary for the "Margaret Island mineral water" / 37-38 °C / thermal mineral water of the Margitszigeti É. III well to be declared medicinal water.

Research Question Primary objective: Effect of bathing in the "Margaret Island mineral water" thermal mineral water of the Margaret Island III well on the performance and potential pain of athletes. Randomized, controlled, single-blind study.

Secondary objective: To what extent does thermal water treatment lead to a change in the quality of life of those receiving it compared to their initial condition, and what is the magnitude of this change compared to the control group?
