Research on the Enhancement of Aerobic Metabolic Energy Supply Capacity by Ischemic Preconditioning.

Ischemic Preconditioning Enhances Aerobic Metabolic Energy Supply Capacity During Frequency Speed of Kick Test in Taekwondo Athletes: A Randomized Crossover Study

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.

Inclusion Criteria:

• adult male athletes aged 18 years or older;
• taekwondo athletes classified as national second-class or above (having placed in the top three provincial professional taekwondo championships or the top eight national professional taekwondo championships);
• consistent and unified training over the past three months;
• no prior ischemic preconditioning;
• competitive taekwondo athletes.

Exclusion Criteria:

• supplementation with creatine;
• acute or chronic illnesses, including anxiety, depression, cardiovascular diseases, and metabolic disorders;
• engaging in vigorous physical activity within 48 hours prior to the experiment;
• consuming alcohol or caffeine within 24 hours before the experiment.
