title: [The peripheral component during dynamic muscular exertion: study of a group of basketball players].
abstract: The peripheral factor (PF), i.e. the ratio: artero-venous oxygen extraction to total peripheral resistences, has been studied in a total of 8 professional basket players under controlled work-load conditions. The results obtained by continuous monitoring heart rate, oxygen consumption, pulmonary ventilation, arterial blood pressure etc, have shown that from 0 to 150 watt work-load, the PF increases linearly showing a slope of 83 degrees, whereas from 150 to 200 watt the pendence reduces up to 45 degrees. The absolute value of PF from a resting value of 3.83 mlo2 X min-1 X mmHg-1 increases up to 21,64 (at 150 watt) and to a maximum of 23.45 mlo2 X min-1 X mmHg-1 at 200 watt. The slope of the first range of load (83 degrees) is quite similar to what previously observed in endurance athletes (cyclists) whereas the 45 degrees angular coefficient indicates that the increased energy demand in basket-players can be obtained only with a large cardiac load.
