Ischemic preconditioning enhances energy supply during frequency speed kick test in Taekwondo athletes: A randomized crossover study
Fig 2
The box plot scatter diagram illustrates the basic indicators and sports intensity.
a: Blood lactate levels during various states: at rest, postintervention, prior to the specific test, three minutes after the specific test, and ten minutes after the specific test. The label ‘Post-intv’ refers to blood lactate levels measured after the experimental intervention. The box in the figure represents the mean ± standard deviation, where the white dots within the box represent the average value, and the horizontal line denotes the median. Each scattered point corresponds to an individual sample value. b: The figure illustrates the average heart rates recorded during three distinct conditions: the quiet state, warm-up kicks, and specific tests. Peak HR: Peak heart rate during testing. c: The graph illustrates the blood lactate clearance rate from 3--10 minutes post-test. * indicates that the data conform to a normal distribution. A paired sample t test was employed, revealing a significant difference between the trials, with a p value of less than 0.05.
