Abstracts
Background and Purpose: We wanted to investigate gender differences in parasympathetic reactivation from supramaximal exercise.

Materials and methods: Parasympathetic reactivation from a Wingate
anaerobic test was investigated in 16 male and 15 female volunteers. Heart rate recovery was assessed as the difference between peak exercise heart rate and heart rate recorded following 60 seconds of recovery (HRR60 ). The time constant of the first 30 s post-exercise HR (T30) was determined as a negative reciprocal of the slope of the regression line. Another time constant decay (T) was obtained by fitting the 5 minute post-exercise HRR into a first-order
exponential curve. Measures of heart rate variability (HRV) were used to describe the changes in autonomic cardiac regulation following exercise.

Results: Post exercise heart rate recovery was faster in male participants, demonstrated through HRR60 (29.5±8.9 vs. 23.4±9.8 seconds respectively) and T30 (292.4±88.7 vs. 409.2±138.3 seconds respectively), but the time constant of the exponential heart rate decay (T) did not differ between the two genders (140.4±55.7 in males and 130.3±49.7seconds in females). The present study demonstrated similar RMSSD, lnHF and HFnu at rest in male and female participants. The time course of RMSSD30 recovery was
impaired immediately after exercise. None of the observed vagal HRV indices have restored after five minutes of recovery following the 30-s Wingate test, but the post-exercise lnHF2-5min was significantly smaller in females (3.3±0.9 ms 2 in males vs. 2.5±1.0 ms 2 in females).

Conclusion: The immediate HRR and parasympathetic reactivation
was affected by gender and was attenuated in female participants.
