The aim of the study is to assess the impact of the rehabilitation and treatment stay at the underground Health Resort of the 'Wieliczka' Salt Mine in Wieliczka on the functional capacity, respiratory parameters, and rheological properties of blood in elderly individuals with respiratory diseases.
The research project will involve patients aged 65 and older with chronic respiratory diseases. Based on controlled studies conducted at the Health Resort "Wieliczka" Salt Mine in Wieliczka, and assuming the project will be a prospective, experimental, controlled study with a crossover design, calculations were made for the primary variable under investigation (exercise tolerance). These calculations determined that 29 pairs of participants are needed to achieve a statistical power of 80% and a significance level of 5% (bilateral). To detect a mean difference between pairs of 58, assuming a standard deviation of 106 for these differences and accounting for a 10% loss of participants from observation, the required sample size was increased to 33 pairs. Given the crossover design, the study plans to include 33 patients.
Volunteers will undergo qualifying tests, measurements of functional fitness, respiratory indicators, and blood rheology tests 3 weeks prior to the start of the rehabilitation and therapeutic stay in the underground salt chambers (1st test). During the 3-week period before the rehabilitation, participants will not engage in any other form of therapeutic rehabilitation. Functional fitness, respiratory indicators, and blood rheology tests will be repeated before the start of the stay (2nd test), immediately after its completion (3rd test), and 3 months after its completion (4th follow-up test). Each day of the rehabilitation and therapeutic stay will include a 2.5-hour visit to the underground health resort under the supervision of a doctor, physiotherapist, and nurse, during which pulmonary rehabilitation will be implemented.

It includes 15 dimensions, covering aspects of physical, mental, and social well-being.Minimum Value: 0 (representing the worst possible health state) Maximum Value: 1 (representing the best possible health state). Higher Scores indicate better health-related quality of life, reflecting higher levels of functioning and well-being across the 15 dimensions. | up to 18 months |

| TNF-alfa | Tumor Necrosis Factor alpha (TNF-α) is a key pro-inflammatory cytokine involved in the regulation of immune responses, inflammation, and apoptosis. It is produced primarily by activated macrophages, but also by T lymphocytes, natural killer (NK) cells, and other immune and non-immune cells in response to infection, injury, or immune stimulation. | up to 18 months |
| WBC [10⁹/l] | White Blood Cell Count - WBC [10⁹/l] Represents the number of leukocytes in one liter of blood. WBCs play a crucial role in immune defense.
