简要总结
This study aims to investigate the differences in cardiovascular stress response patterns among individuals with various physical activity levels (sedentary controls and different types of athletes). By synchronously monitoring ECG, heart rate, skin sympathetic nerve activity (SKNA), blood pressure, and cardiac output, the study will characterize physiological dynamics during resting, orthostatic challenge, cold pressor stress, and maximal exercise.
详细描述
Participants will be categorized into five groups based on their training background: sedentary, endurance, strength, technical, and traditional ethnic sports. The experimental protocol includes baseline measurements in lying, standing, and sitting positions, followed by a series of acute stress tests: a lie-to-stand orthostatic test, a slow breathing test, and a cold pressor test. Finally, participants will perform a ramp incremental exercise test on a cycle ergometer. Synchronous physiological data including HRV and SKNA will be collected to evaluate the dynamic regulation of the autonomic nervous system.
