Research Abstract	The BI time derivative was evaluated and the point at which this BI derivative began to increase was defined as the bending point (BP). Significant negative correlations were observed between BI and both oxygen consumption and heart rate, which indicate exercise intensity. Therefore, we conclude that changes in BI might offer quantitative indications of changes in leg blood volume. Furthermore, close correlations between BI derivative and RCP suggest that metabolic change caused by lactate buffering limitation might induce additional changes such as redistribution of blood during exercise. We found that BP increased after exercise training. It will be possible to make exercise prescription from BP point.
