Introduction: The recommendation for regular physical exercise is well described and well founded, but there are barriers that hinder its practice and contribute to a growing sedentary population and at risk for cardiovascular diseases. Alternatively, interval training (IT) is performed in time. reduced. To evaluate these factors, Heart Rate Variability is an effective marker that reflects the autonomic modulation of CF and consequently health prognosis. This study aimed to compare the effects of eight weeks of IT training on HR and HRV kinetics responses in healthy women. Methodology: A randomized clinical trial conducted with 43 healthy women, who after HRV assessment, cardiopulmonary exercise test and HR kinetics were allocated into two groups, the High Intensity interval training consisting of 4 efforts of 4 min. at 90-95% of HRpeak interspersed for 3 min. 50-60% recovery from FCpico, and Sprint Interval Training 4 30-second all-out efforts interspersed with 4 min. With no active recovery, the protocols were performed for 8 weeks on alternate days. After the intervention period they were reevaluated. The tests used were 2-way ANOVA and Ancova. Results: Two-way ANOVA revealed group effect only in V O2peak and time effect in VO2peak, RMSSD, SDNN, SD1 and SD2. Conclusion: Although these are different types of IT both showed benefits regarding HRV and HR kinetics.
