Evaluation of exercise therapy on peripheral hemodynamic changes and exercise tolerance in various health stages

评估BI时间导数，并将该BI导数开始增加的点定义为弯曲点(BP)。BI与反映运动强度的耗氧量和心率呈显著负相关。因此，我们得出结论，BI的变化可能提供腿部血量变化的量化指标。此外，BI导数和RCP之间的密切相关性表明，乳酸缓冲限制引起的代谢变化可能会导致额外的变化，如运动中血液的重新分配。我们发现运动训练后血压升高。从BP点开始制定运动处方将成为可能。

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.
