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

Ziyue Ou16 enrolled

Overview

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.

Outcomes

Primary Outcomes

Oxygen uptake

To record the oxygen uptake of the subjects and compare the changes in oxygen uptake after the intervention.

Time frame: Participants had their oxygen uptake measured continuously during both visits, extending until six minutes after the completion of the exercise test.

Taekwondo-specific sports performance test

The specialized athletic ability in Taekwondo is measured by the number of kicks performed during the test.

Time frame: 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.

Blood lactate

Used to measure the intensity and metabolic adaptations during the testing process of taekwondo athletes

Time frame: Blood lactate levels were measured at baseline, immediately after the intervention at 3 minutes, and at 3 and 10 minutes post-testing.
