[The "peripheral factor" in muscular exertion].
On the basis of their own experimental results and of those from the literature, the Authors have studied the possibility of bloodless evaluation of the ratio: oxygen extraction (DAV) to total peripheral resistances (TPR). The so called "peripheral factor" which can be thus obtained (units: m10(2) X min-1 X mmHg-1), appears to be a sensitive index of the metabolic-functional behaviour of skeletal musculature and of the degree of left ventricular involvement during various types of muscular exercise. From resting value of 3-5, the "peripheral factor" can increase up to 40 m10(2) X min-1 X mmHg-1 in well trained athletes, and it appears to be influenced not only by the amount of work performed but also by the "type" of muscle group involved.
