Abstract [eng] The work aimed to investigate the changes in oxygen levels (SmO2) in the muscles of World-class kayak athletes during special physical exercises. Organisation and methods of the research. One elite kayak athlete, a prize winner in World and European championships and Olympic games in a 1000 m kayak flat water race event, aged 30 (height of 184.5 cm, body mass of 89 kg.), participated in the study. Two physically different loads while working on an ergometer (Dansprint PRO, KE001) were applied: the high-intensity interval method (the 60s, 200W during the working phase and 60s, 40 during the rest phase) (HIIT) and the highintensity short-distance sprint interval (10s, 30W during working phase and 30s, 40W during rest phase) (HIST) method. A total of six repeated series were performed. NIRS monitors were placed on the left (dominant)Vastus Lateralis, Pectoralis Major, and Latissimus Dorsi muscles. The heart rate (b./min.) and lactate in the blood (mmol/l) were also measured. Results: Studies showed that two different training sessions significantly affect oxygenation processes in active muscles. During HIST, SmO2 decreased 10% more than during HIIT. During the 6-minute recovery phase, SmO2 returns to baseline level before exercise in both cases. Muscle oxygenation had the greatest variations in the Pectoralis Major muscle and the smallest 7% variations in the Vastus Lateralis muscle. Lactate concentration in blood was lower after HIST than in HIIT. Conclusion. Muscle oxygenation responding to training stimuli can provide valuable insights as internal predictors of hemodynamic and metabolic changes. Data regarding oxygenation across different muscles can help us gain insights into the internal load of kayak movements. However, this area requires further research.
