Effects of Changes in the Taekwondo Competition System on Match and Training Load: A Longitudinal Analysis Across 2021–2023
This longitudinal study demonstrates that the 2022 World Taekwondo competition system revision altered technical-tactical behaviors and match loads, while an eight-week specialized training program significantly improved elite male athletes' kicking force, fatigue tolerance, and overall performance across 2021–2023.

The Big Picture: Changing the Rules of the Game
Imagine Taekwondo as a high-speed video game. For years, players (athletes) have mastered the game based on a specific set of rules. But in 2022, the game developers (World Taekwondo) hit "Update 2.0." They changed how points are scored, how rounds work, and what counts as a win.
This study is like a group of researchers watching a group of pro gamers (20 elite male athletes) play this game over three years: 2021 (before the update), 2022 (right after the update), and 2023 (after they had time to adapt). The researchers wanted to see:
- How did the new rules change the way they played?
- Did the new rules make the game more exhausting?
- Could a special training program help them get better at the new version?
The Players and the Setup
The study followed 20 elite male athletes. Think of them as the "Pro League" players. They are young (around 20 years old), tall, and have been training for about 9 years.
The researchers put them through a three-part test every year:
- The Simulation: They fought three 2-minute matches that looked exactly like real tournaments, using electronic armor that measures how hard they kick.
- The "Kick Sprint" Test (FSKT): This is like a sprint test for their legs. They kicked as fast as they could for 10 seconds, rested for 10 seconds, and repeated this five times. It measures how fast they are and how quickly they get tired.
- The "How Hard Was It?" Check (RPE): After every round, the athletes rated how exhausted they felt on a scale of 0 to 10.
What Happened When the Rules Changed? (2021 vs. 2022)
When the 2022 rules came out, the athletes had to relearn how to play. The researchers found that the "Update 2.0" forced the players to change their strategy:
- More Variety: Before the update, players might have stuck to a few favorite moves. After the update, they started using a wider variety of kicks, like a chef suddenly adding new spices to their cooking.
- New Favorite Moves: The most popular kick changed. Before, the "Roundhouse Kick" (Dollyo Chagi) was the go-to. After the update, the "Side Kick" (Yop Chagi) and the "Front Jumping Kick" (Baldeung Chagi) became the stars of the show.
- More Exhaustion: The new rules made the game feel harder. In 2022 and 2023, the athletes rated their effort (RPE) higher than they did in 2021. It was like the game speed increased, making the players feel more out of breath.
The Training Program: The "Coach's Cheat Code"
To help the athletes handle this new, harder version of the game, the researchers designed an 8-week training program. Think of this as a specialized "boot camp" designed specifically for the new rules.
The training wasn't just about running or lifting weights; it was a mix of:
- Technical Drills: Practicing the specific kicks that worked best under the new rules.
- Interval Training: This is like a "stop-and-go" game. They would kick hard for a short time, rest briefly, and kick hard again. This mimics the stop-and-start nature of a real match.
- High-Intensity Sprints: Short bursts of maximum effort to build explosive power.
The Results: Did the Training Work?
Yes, the training worked like a charm. Here is what happened after the 8 weeks:
- They Got Stronger: The athletes kicked harder. Their "impact force" increased, meaning their punches and kicks hit the electronic armor with more power.
- They Got Faster and Less Tired: In the "Kick Sprint" test, the athletes were able to kick more times in total. More importantly, they didn't slow down as much at the end of the test. They became better at resisting fatigue.
- The Game Felt Easier: Even though they were working harder, the athletes reported feeling less exhausted (lower RPE scores) after the training. It's like running a race: before training, a 5-mile run feels like a marathon; after training, it feels like a jog. They had built a better "engine" to handle the load.
The Takeaway
The study concludes that when the rules of Taekwondo changed in 2022, the athletes had to adapt their style, which initially made the game feel more physically demanding. However, by using a training program that specifically targeted the new demands (mixing technique with high-intensity intervals), the athletes were able to:
- Master the new scoring techniques.
- Kick harder and faster.
- Feel less tired during the match.
In short, the study shows that you can't just train the same way forever. If the game changes, the training must change with it to keep the players at the top of their game.
