Abstract :The aim of this study is to examine the changes in HRV values before, during insert ignore into journalissuearticles values(at AT and RC); and after maximal incremental cardiopulmonary exercise test. The sample comprised 121 healthy men who recreational do exercise 2-3 days a week. insert ignore into journalissuearticles values(age: 30.5 ± 4.6 years, height: 177.8 ± 6.1 cm; weight: 80.2 ± 10.2 kg);. Anthropometric measurements were measured by using body analyzer, and aerobic capacities of participants were measured by using the cardiopulmonary exercise test via the Bruce protocol. According to this, heart rate variability recordings were taken at seven stages during the cardiopulmonary exercise test: before the test insert ignore into journalissuearticles values(1);, at the beginning of the test insert ignore into journalissuearticles values(2);, between the beginning of the test and the anaerobic threshold insert ignore into journalissuearticles values(3);, at the anaerobic threshold insert ignore into journalissuearticles values(4);, between the anaerobic threshold and the respiratory threshold insert ignore into journalissuearticles values(5);, at the respiratory threshold insert ignore into journalissuearticles values(6);, and finally insert ignore into journalissuearticles values(7);, 30 seconds after the cardiopulmonary exercise test. Repeated measures analysis of variance insert ignore into journalissuearticles values(ANOVA); was used to compare the HRV values obtained from the test stages. In conclusion, using a gas analyzer during cardiovascular exercise testing, HRV values insert ignore into journalissuearticles values(MeanRR, SDNN, RMSSD, LFnu); determined at seven stages continue to decrease from the beginning. A rest period of 30 seconds insert ignore into journalissuearticles values(passive rest); immediately after completing the exercise does not seem to be sufficient for recovery. According to the results of this study, it can be considered that the sympathetic nervous system activity insert ignore into journalissuearticles values(LFnu); exhibits a more pronounced appearance at threshold zones.
