Dinámicas de la variabilidad de la frecuencia cardiaca durante diferentes momentos de recuperación de la fatiga después de ejercicios de tipo anaeróbico y aeróbico

Abstract

The purpose of this study was to examine the dynamics of heart rate variability at different times of recovery in high performance athletes after a high intensity workout. Involved 18 college athletes with aerobic and anaerobic training. The recovery was analyzed through heart rate variability with variable time domain for 15 minutes in supine position using the Polar Team2, records were before training (rest), immediately after the training (final), an hour later, two hours later and 24 hours after the training. Within results we show significant differences in the group of anaerobic in MRR (p <0.05) in the final measure with respect to the initial measure and 48 hours after, the rMSSD (p <0.05) in final measure with respect to the rest measure, the pNN50 (p <0.05) between the final measure and 48 hours after training. The aerobic group not showed significant difference between any of the variables. Comparing aerobic and anaerobic group we found significant difference in group MRR (p <0.01) in both aerobic and anaerobic athletes, rMSSD shown significant difference in aerobic athletes (p <.05) and in the Anaerobic a significant difference (p <.01) in the pNN50 we found significant difference (p <.01) for both groups. Consistent with the results found, the aerobic metabolism in trained athletes have better recovery after a workout high intensity.
