Abstract

In this study, the relationships between swimming speed at lactate threshold, critical speed, maximal swimming speed, and swimming speeds at different distances (50m, 100m, 200m, and 400m) with peak oxygen consumption (VO2peak) and corresponding swimming speed were examined in swimmers. For this purpose, participants swum 25m, 50m, 100m, 200m, and 400m maximal swimming tests, as well as a 7x200m incremental test protocol in freestyle. The critical speed was determined from the slope of the regression curve obtained by plotting swimming speeds against corresponding time for different distances swum. Lactate concentration was measured from blood samples taken during the 7x200m incremental test, and the lactate threshold was determined using the lactate inflection point method.The study includes 35 swimmers (16 females and 19 males) aged 15-16, who achieved 500 or more FINA points at the national and international levels. Oxygen consumption is measured using a portable gas analysis system for 20 seconds immediately before exiting the pool after 7x200 test. Oxygen consumption values are determined using a back-estimation formula. Lactic acid measurement is performed from a finger blood sample using a hand analyzer post-tests. The study concludes that both female and male swimmers' critical speeds are found to be 93% of VO2peak swimming speeds, 97% of 200m swimming speeds, and 95% of 400m swimming speeds. Anaerobic threshold swimming speed is found to be 91% of VO2peak speed in males and 87% in females. Significant relationships are found in male swimmers between VO2peak and anaerobic threshold swimming speed, critical speed, 200m, and 400m swimming speeds. Unlike males, female athletes do not show a significant relationship between VO2peak and anaerobic threshold swimming speed. Only in males is there a significant relationship between maximal swimming speed and 50m swimming speed. In male athletes, significant relationships are found between VO2peak swimming speed and anaerobic threshold swimming speed, critical speed, 100m, 200m, and 400m swimming speeds. In contrast to male athletes, no relationship is found between VO2peak swimming speed and critical speed in female athletes.
