• Female athletes
• V(O2max)
• Tredmill
• Autonomic control

Aims. - The main aim of the study was to investigate if different level of aerobic fitness influence heart rate (HR) responses during 10-s intervals of first minute of recovery after maximal exercise in athletes.
Methods. - Thirty female athletes requesting a pre-competition medical examination with exercise-stress testing at the exercise physiology lab, who were participating in consistent training for the past 2 years and who were between 20 and 22 years of age, were recruited for the study. After maximal exercise on treadmill, the end of exercise was flagged, and 1 min of post-exercise HR recorded with the subject at supine position.
Results. - At the both 10 and 20s of recovery period, female athletes with high aerobic capacity (> 50 ml/kg/nnin) had significantly tower HR as compared to their sub-elite counterparts (<40 ml/kg/min) (p<0.05). The results obtained in this study suggest that the female athletes with superior aerobic fitness had lower 10 and 20s recovery HR after maximal exercise than their counterparts with lower aerobic capacity.
Conclusion. - These results seem to indicate that aerobic fitness along with autonomic modulation might have played a rote in the ultra short-term cardiovascular responses to all-out exercise.
