Abstract:
Blood flow and volume change of the thigh were measured in six healthy male subjects in bicycle exercise at varying work rates. Mercury-in-rubber strain gauge plethysmograph technique was used to determin the blood flow and volume change of the thigh.
The thigh blood flow immediately after exercise reached an average of 16.7 ml/ 100 ml⋅min when the work load was 30 watt. It rose progressively with the intensity of the exercise so as to attain 24, 8, 39.4 and 44.4 ml/100 ml⋅min at 60, 120 and 180 watt, respectively.
The thigh volume immediately before stopping the exercise at 30, 60, 120 and 180 watt were 2. 53, 2. 86, 3.68 and 4.33 ml/100 m, min respectively. Furthermore, there are close relationship between the thigh volume immediately before stopping the exercise and the thigh blood flow immediately after exrcise with being statistically significant (r=0.76, P<0.001) .
