Effects of Inspiratory Muscle Training on Performance in Young Swimmers: a Comparison of Land- and Water-based Applications
The aim of this study is to investigate the effects of four weeks of land- and water-based inspiratory muscle training (IMT) on performance and selected physiological variables in young swimmers. A total of 30 competitive swimmers (22 males and 8 females), who have been training regularly for at least two years, will be voluntarily recruited and assigned to three groups: Land + IMT, Swimming + IMT, and Water + IMT. To compare the effects of different training protocols and evaluate their specific contributions to performance, participants will undergo assessments before the intervention and after the completion of the four-week training period. These assessments will include anthropometric measurements, pulmonary function tests, respiratory muscle strength, 100- and 200-meter freestyle swimming performance, stroke rate and stroke efficiency, as well as cardiopulmonary capacity. Previous studies investigating the effects of inspiratory muscle training in swimmers have generally applied the intervention in land-based settings and reported positive physical and physiological adaptations. However, to the best of our knowledge, no previous study has examined the effects of IMT performed in the water in swimmers. This novel approach is expected to better simulate the actual breathing demands encountered during swimming, thereby improving respiratory control, promoting a more efficient breathing rhythm during competition, and enhancing swimming performance.
