This bachelor thesis focuses on the assessment of swimmer fatigue during front crawl swimming using inertial sensors and heart rate monitoring. The aim of the thesis was to analyze changes in selected swimming technique parameters during increasing exercise intensity and to assess their relationship with the physiological response of the organism. The measurement was carried out during repeated maximal swimming intervals in a swimming pool. Data collection was performed using the Movella Xsens DOT inertial sensor and the Polar Verity Sense optical heart rate sensor. The evaluated parameters included stroke rate, stroke length, lateral movement amplitude, maximum acceleration in the direction of movement, and heart rate. Subjective perception of exertion was also assessed using the RPE scale. The results indicated changes in selected swimming technique parameters during increasing exercise intensity and confirmed the applicability of inertial sensors for swimming technique analysis in real training conditions.

Process of defence
Student prezentoval výsledky své práce a komise byla seznámena s posudky. Doc. Kumstát položil otázku, zda práce vycházela z existujících studií, zejména při návrhu a nastavení měřicího protokolu. Dále se dotázal, zda existuje prokázaný vztah mezi výsledným časem na plavecké trati, například na 100 m, a frekvencí plaveckých záběrů. Student obhájil bakalářskou práci s výhradami a odpověděl na otázky členů komise a oponenta.
