简要总结
The purpose of this clinical trial is to investigate whether IPC can improve aerobic capacity during exercise. The primary question it aims to answer is: Does IPC enhance the aerobic capacity of athletes? The researchers will compare IPC (220 mmHg pressure) with a placebo (20 mmHg pressure) to see if different interventions can enhance aerobic capacity and exercise performance.
Participants will:
- Undergo a randomized crossover controlled trial, visiting twice, with a one-week interval between each test.
- Conduct two assessments at the testing site each time, namely a pre-intervention assessment and a post-intervention assessment.
- Record their heart rate, blood pressure, weight, oxygen uptake, Taekwondo-specific performance, and other indicators.

结局指标
主要结局
Taekwondo-specific sports performance test
时间窗: The subjects rested quietly for five minutes before baseline measurements were taken. After this, the collection of metabolic gases commenced. Throughout the experiment, metabolic gases were continuously collected until six minutes after the tests.
The specialized athletic ability in Taekwondo is measured by the number of kicks performed during the test.
Blood lactate
时间窗: Blood lactate levels were measured at baseline, immediately after the intervention at 3 minutes, and at 3 and 10 minutes post-testing.
Used to measure the intensity and metabolic adaptations during the testing process of taekwondo athletes
Oxygen uptake
时间窗: Participants had their oxygen uptake measured continuously during both visits, extending until six minutes after the completion of the exercise test.
To record the oxygen uptake of the subjects and compare the changes in oxygen uptake after the intervention.
