Typical magnitude of mean blood velocity, BP, EMGs, and muscle contraction power during repeated IMC and muscle relaxation at 50 % MVC. The beat-to-beat mean blood velocity (MBV) was higher in the muscle relaxation (MR) than in the isometric muscle contraction (IMC) phase due to higher muscle contraction power (intramuscular pressure) restricting blood flow perfusion during IMC. The complete consecutive beat-by-beat blood velocity profile (only in completed systole and diastole forms in →|*|←) during 10-s IMC or 10-s MR phase was measured. A fragment of the blood velocity profile in the gap (G) between IMC and MR was not included in the evaluations. %MVC percentage of maximum voluntary contraction, EMGs surface electromyography, BP blood pressure
