N2 - Assessment of perfusion adaptation in muscle during exercise can provide diagnostic information on cardiac and endothelial diseases. Power Doppler Ultrasound (PDUS) is known for its feasibility in the non-invasive measurement of moving blood volume (MBV), a perfusion related parameter. In this study, we show how PDUS can be used to assess the MBV kinetics in muscle, before, during, and after exercise. In a volunteer study, PDUS signal was obtained continuously on the gastrocnemius muscle and rectus femoris muscle, during calf raise (N=11) and leg extension exercises (N=11), respectively. To test reproducibility, the measurements were repeated on two different days. A clear increase of PDUS signal was obtained in both exercises. MBV kinetics during leg extension and after calf raise are assessed by linear and mono-exponential fitting of the data. The reproducibility of the obtained slope and time constants of the signal increase and decay were moderate to good between measurement days, with intra-class correlations (ICC) values of 0.6 - 0.8. Future studies will focus on protocol standardization and the monitoring of muscle perfusion during whole body exercise.
