Ischemic preconditioning enhances energy supply during frequency speed kick test in Taekwondo athletes: A randomized crossover study.
Trial report in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis study aimed to examine the effect of ischemic preconditioning (IPC) on energy supply during sport-specific tests in male taekwondo athletes. To our knowledge, this is the first investigation of IPC's efficacy in enhancing energy supply in a taekwondo context, underscoring its potential to optimize performance in combat sports.
methodsSixteen male taekwondo athletes completed a randomized crossover trial comparing an IPC condition (220 mmHg) with a sham condition (20 mmHg). Performance was evaluated via the frequency speed kick test (FSKT), and energy system contributions were quantified via the PCr-La-O₂ method. Two-way repeated-measures ANOVA and a generalized linear mixed model were used to analyze the data.
resultsIPC significantly increased the total number of kicks in each FSKT group (98.4 ± 6.6 vs. 94.0 ± 5.5, p = 0.049, d = 0.72; 94.4 ± 7.7 vs. 89.3 ± 5.5, p = 0.036, d = 0.77; 93.1 ± 7.5 vs. 86.8 ± 6.3, p = 0.015, d = 0.90) and the aerobic energy supply (294.09 ± 50.35 vs. 270.44 ± 49.30, P = 0.031, d = 0.47). The postexercise blood lactate clearance rate was greater in the IPC trial (14.07 ± 4.94 vs. 9.14 ± 6.84, p = 0.02, d = 0.81), despite no differences in glycolytic or phosphagen contributions (49.32 ± 13.11 vs. 43.00 ± 12.25, p = 0.055).
conclusionIPC appears to enhance taekwondo performance by improving aerobic metabolism and accelerating lactate clearance, thereby promoting synergistic interactions between anaerobic and aerobic energy systems and improving energy supply. Notably, the performance benefits of IPC became more pronounced as exercise duration increased, suggesting a cumulative ergogenic effect during prolonged high-intensity activity.
