Research on the Enhancement of Aerobic Metabolic Energy Supply Capacity by Ischemic Preconditioning.
China16 participantsStarted 2024-04-01
Plain-language summary
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.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Oxygen uptake
Timeframe: Participants had their oxygen uptake measured continuously during both visits, extending until six minutes after the completion of the exercise test.
2
Taekwondo-specific sports performance test
Timeframe: 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.
3
Blood lactate
Timeframe: Blood lactate levels were measured at baseline, immediately after the intervention at 3 minutes, and at 3 and 10 minutes post-testing.
