 note = {The purpose of this study was to assess intramuscular blood flow dynamics during incremental muscle contractions using power Doppler ultrasonography. A 23-year-old man performed intermittent isometric knee extensions (5-s contraction with 5-s rest) at 30%, 40%, 50%, 60%, and 70% of maximal voluntary contraction (MVC) until task failure. Intramuscular blood flow of the vastus lateralis at the mid-thigh was continuously measured using the ultrasonography, and monitor screen images were transferred to a personal computer as a video format at 20 fps during the measurement. To quantify the intramuscular blood flow, the relative area occupied by power Doppler signals which indicate distribution of blood flow to cross-sectional area (CSA) of the vastus lateralis was measured. Intramuscular blood flow gradually increased in proportion to exercise intensity, then it reached plateau at just before the exhaustion. It is unclear whether this is a typical pattern of changes in intramuscular blood flow based on power Doppler ultrasonography because the data was obtained from only one participant; however, we plan to increase the number of participants in the near future. In addition, it can be expected to be applied power Doppler ultrasonography to various measurements because it can assess intramuscular blood flow dynamics.},
