Outline of Final Research Achievements |
This study aims to investigate the effect of breathing technique on passive drag during underwater towing. We attempted to evaluate the breathing technique in swimmer's streamline posture by simultaneously measuring lung capacity and passive drag under water. Differences in breathing technique were evaluated with a pickup device attached to the chest and abdomen of the subject. Resistance was measured by the device equipped with a force sensor and a tachometer on the electric reel. The abdominal breathing increased ventilation compared to chest breathing, resistance at towing decreased. The results suggested that abdominal respiration may be contribute to reducing resistance during the streamline posture under water.
