The study involving 35 sportsmen and 35 non-sportsmen was undertaken to assess the reactivity of human heart sinus node in response to physical workload depending on the initial state of the blood circulation system. It is found that sportsmen have predominantly a hyperreactive type and non-sportsmen--a hyporeactive type of sinus node reactivity to workloads. Moreover, the reactivity of heart sinus node in response to physical workload depends considerably on the initial state of the system of blood circulation regulation at a relative rest. The regression equation for assessment of heart sinus node reactivity to workload is proposed.
这项研究涉及35名运动员和35名非运动员，旨在根据血液循环系统的初始状态，评估人类心脏窦房结对体力负荷的反应性。研究发现，运动员的窦房结对负荷主要表现为高反应型，而非运动员则为低反应型。此外，心脏窦房结对体力负荷的反应性在很大程度上取决于相对休息时血液循环调节系统的初始状态。本文提出了评估心脏窦房结对负荷反应性的回归方程。
