 | | Isotonic muscle contraction causes a rise in the heart rate and a marked increase in stroke volume that results in an increase in cardiac output and a net decrease in peripheral resistance (due to vasodilatation of contracted muscles). |
 | | As with the isotonic dynamic exercise, the intensity, frequency, and duration of isometric static exercise must be established for each patient individually, according to the results of the prior medical evaluation (see Medical evaluation). |
 | | As a preliminary exercise prior to isotonic or isometric training, PROM should be performed during the first warm-up and the last cool-down phases. |
