Association between maximal aerobic capacity and heart rate variability

Relevance. Сardiovascular status could be assessed by maximal aerobic capacity (VO2max) through direct analysis of the gases involved in pulmonary ventilation and monitoring fluctuations intervals between beats over time as heart rate variability. The aim study was to investigate relationship VO2max variability young adults. Materials Methods. A total 100 adults ages 18 25 were included observational study, who did not engage any strenuous physical activity, 50 whom male female.There measured Heart frequency domain; LF, HF, LF/HF, SDNN, RMSSD, pNN 50, using a treadmill test according Graded Exercise Protocol. Results Discussion. There weak positive correlation with LF ( r = 0.177) negative HF -0.141). Male participants had VO2 max -0.075), whereas female respondents relationship(r 0.286). LF/HF ratio for subjects but -0.101) subjects. For participants, there association SDNN -0.170) -0.301), respectively. -0.154) -0.284) slight -0.062) -0.441) Conclusion. Significant variations found domain indices including which represents balance sympathetic parasympathetic responses.
