| Outline of Final Research Achievements |
we set our goal to construct a real-time measuring system for the distance (D) between center of buoyancy (CB) and center of mass (CM), measuring the vertical direction of force on the hands and legs corresponding to the changes in the ventilation volume, where the swimmer is in a horizontal posture in the water and is breathing freely with a snorkel, and to examine the relationship between D and swimming performance based on changes in the force exerted in a vertical direction on hands and feet with changes in lung ventilation.
The relationship between the ventilation volume and force exerted in a vertical direction on the hand area and leg area, and D indicated extremely good linearity, respectively. Moreover, D in the neutral buoyancy of the swimmers was significantly shorter than that of non-swimmers. Therefore, it is thought that this measuring system can be utilized as an effective method for evaluating swimming performance.
