Untrained men's peripheral hemodynamic responses to graded physical loads

The study tested and analyzed the key regularities of the lower-limb blood circulation system responses, with healthy untrained men aged 17-20 years being subject to the tests by graded physical workloads. The study found the workloads on the locomotor system being associated with variations of many peripheral hemodynamic system performance rates indicative of the tonuses of the large and small vessels, blood inflow and venous outflow. The study found a few correlations of the blood flow rates with durations of the graded physical workloads, with the variations of the central hemodynamic characteristics being probably due to the interdependent settings of the central and peripheral (local) regulatory mechanisms. The latter may contribute to the working capacity reserve building process through the blood flow being redistributed in favour of the working muscular groups.
