The aim of this study was to demonstrate and compare physiological performance and different anaerobic threshold determination methods in rowers. 18 rowers participated in this study voluntarily(age 17.38±0.6 years). Besides the measurements of height and weight, subjects performed 2000 meter maximal rowing ergometer test and incremental rowing ergometer test which is recommended by Australian sports institute. The incremental test consists of 7 progressive stages of 4 minutes with 1 minute rest intervals. Blood samples for lactate analysis were collected at rest. Oxygen uptake kinetics also measured via ergospirometer during test. Results of Pearson product moment correlations indicated that significant relationships between the values of r=0.85 and r=0.99 were determined in absolute and relative VO2, heart rate, power and workload at lactate threshold, ventilator threshold and 4 mmol anaerobic threshold (p Bu çaly?mada; kürekçilerde fizyolojik performansy ortaya koymak ve anaerobik e?i?in belirlenmesi için kullanylan farkly yöntemleri kar?yla?tyrarak aralaryndaki ili?kileri belirlemek amaçlanmy?tyr.
