Among all sports, which one is the fastest? Is it Shohei Ohtani’s blazing fastball? Is it Lewis Hamilton’s Scuderia Ferrari racing down the longest straight of a track? Or is it the thunderous serve struck by Giovanni Mpetshi Perricard at Wimbledon?
In fact, there is a sport even faster than all of these. It is badminton. At the highest level of the game, a smash can reach speeds of 400 to 500 kilometers per hour. Although it may look simple at first glance, the speed of the shuttlecock is astonishing.
The reason badminton is so fast lies in the structure of the shuttlecock. The shuttlecock is shaped with feathers, which create a great deal of air resistance, but when a player unleashes a powerful smash, it shoots forward at incredible speed in that first instant. In that brief moment, the opponent must judge the direction and speed and move immediately. Even the slightest delay in reaction can easily cost a point.
Badminton rallies are also played at an extraordinary pace. Players sprint across the entire court, constantly shifting between attack and defense. Footwork, reflexes, and instant decision making are all essential. For that reason, badminton is not simply a sport that requires arm strength. It demands speed, endurance, and strategy at the same time.
In a sport that requires such speed, dynamism, and intelligence, the most remarkable player today is women’s singles star An Se-young. For many years, Chinese players dominated women’s singles, but she has now become a player whom no one can easily overcome. In 2024 she became an Olympic champion, and in 2025 she won more tournaments in a single year than any badminton player in history. As of 2026, she has not lost a single match and is currently riding a 36-match winning streak.
As someone who has watched badminton for many years, I have never seen a player who reads the direction of the shuttlecock and reacts even faster with her body the way An Se-young does. No other player can match her instant judgment and lightning-quick footwork. She may well be one of the greatest players in the history of badminton.
Her endurance is just as extraordinary. No matter how long a rally becomes, she continues moving with agility and maintains her focus until the very end. Even when opponents unleash a series of powerful smashes, she often retrieves them again and again, keeping the rally alive. This kind of relentless defense puts enormous pressure on her opponents.
Her intelligence and strategy are equally impressive. An Se-young is not simply a player who returns the shuttlecock. She plays while already thinking about the next situation. She reads where her opponent is moving and attacks the open space on the court.
In the end, An Se-young is a player who possesses all the qualities required in badminton. She remains calm even in the fastest exchanges, sustains her endurance during long rallies, and chooses the right strategy for each moment.
Her movements are pure joy to watch. When power is needed, she plays with strength, and when delicate skill is required, she produces amazingly refined shots. Her concentration and precision are so complete that opponents sometimes seem to lose hope during a match. Watching her play often feels like watching Roger Federer’s tennis in the mid-2000s.
At only twenty-four years old, she is not at the end of her prime but rather approaching the peak of her career. If she can avoid major injuries, the women’s singles stage in badminton will belong to An Se-young for the next four or five years.
Check out this match from the 2026 All England Open Badminton Championships between An Se-young and Chen Yufei, the Olympic champion from 2020. It is a great way to see An Se-young at her best. Her footwork, concentration, defensive ability, and lightning-fast reflexes are astonishing and will truly blow your mind.
