Measurement of exercise-induced muscular hyperaemia with colour duplex ultrasonography

Muscular activity results in increased muscular perfusion. Only few publications have shown colour duplex ultrasonography to be useful in measuring vascularisation of the muscle tissue quantitatively. Purpose of the present study was to answer whether exercise-induced muscular hyperaemia can be depicted by means of colour duplex ultrasonography and check the time course of this hyperaemia. Twenty-five healthy males, aged 18 to 60 years, were examined. The dominant arm was strained isometrically randomly over 15, 30, and 60s with 10%, 20%, 30%, 40%, and 50% of the maximum voluntary contraction (MVC). Thereafter u…
