Outline of Final Research Achievements

Diving bradycardia has been observed to occur due to facial cooling and breath-holding, and reflected parasympathetic regulation. The purpose of this study was to investigate the effects of age and physical fitness on diving bradycardia and post-exercise heart rate recovery. The present study suggests that diving bradycardia and heart rate recovery both decreased with increasing age, and both decreased in people with low physical fitness than in people with high physical fitness. Diving bradycardia may be affected by ageing and physical fitness, and evaluate parasympathetic regulation easily.
