Southeast Asian badminton between two Olympic cycles: Indonesia dismantles and rebuilds, Vietnam searches for a springboard

5:12 a.m. in Cipayung

Only three banks of lights were on in the training hall that morning. Yellow light fell onto the plastic-wood floor, where the green had faded to ash grey. A pair of shoes had been placed neatly by the door, toes pointing inward, the right sole worn down to the white rubber. The sound of a shuttle being struck against a racket face rose and fell, slow then fast, like someone counting something that was not points.

The player was a doubles athlete who had never reached a Super 1000 final. He trained alone. The session lasted ninety minutes: twenty minutes of band warm-up, thirty minutes of driving shuttles into a wall, forty minutes of six-point court movement against a coach holding a basket of shuttles. No crowd. No camera. No one with a stopwatch.

I sat in the top row, where nobody bothers to dust, and recorded every shuttle sound. Sixteen years in this job have taught me one thing: the moments that decide the fate of a badminton nation are not found in an All England final, nor in an Olympic medal ceremony. They are found in mornings like this, when one person trains alone in an empty hall, and nobody knows that three years later he will be standing at the service line in an Olympic quarterfinal.

I write from Jakarta, where I have lived for years, but I still keep a Vietnamese pulse in every sentence. What I want to tell is not a specific tournament. It is the gap between two Olympic cycles — the quiet stretch the media calls the regular season, and the people in the trade call the period that decides who survives.

The regular season and a rhythm that lets nobody rest

After Paris 2026, world badminton entered a new cycle. The BWF World Tour calendar kept its number of events and even thickened at the Super 300 and Super 100 tiers — the tier that players ranked 30 to 80 must grind through to protect their entries into bigger events. For viewers, this is the least glamorous stretch of any four-year period. For athletes, it is the harshest.

In the last three matches I watched live at Istora Senayan, one pattern repeated: Southeast Asian players entering a third game with a sharp rise in unforced errors. Not because they are mentally weak. Because of the calendar. A men's singles player ranked 40 who wants to stay in the top 40 must play twenty to twenty-four weeks a year, moving between East Asia, Europe and Southeast Asia, and every time zone change forces the body to reprogram itself.

The uncomfortable truth of the regular season is this: the ranking system rewards the player who competes the most weeks, not the player who is best when it matters most.

I have sat through enough press conferences to know that every Southeast Asian coach says the same sentence: "We need preparation time." The calendar does not give time back. The shuttle still falls according to gravity.

Indonesia: Pelatnas as a construction site

Indonesia's national training centre in Cipayung — known across the badminton world simply as Pelatnas — has looked more like a building site than a national team for the past two years.

After Paris 2026, where Indonesia took home only a bronze medal from Gregoria Mariska Tunjung in women's singles, the PBSI leadership faced a question it had avoided for a decade: restructure, or keep living on memory?

Indonesia's memory is beautiful. From Barcelona 2026 with Susi Susanti and Alan Budikusuma, through the golden years of men's doubles, through Taufik Hidayat in Athens 2026, through Greysia Polii and Apriyani Rahayu in Tokyo 2026. Southeast Asia holds a badminton tradition the rest of the world once looked up to, and Indonesia is its heart.

But memory does not help an eighteen-year-old who needs a training room with motion sensors.

What I observed in open sessions at Cipayung points to three systemic changes.

The first is how training groups are divided. Men's doubles used to be one bloc under a single head coach, built around a philosophy of the anchor pair. After Paris, the group was split into smaller units by physique and style: front-court attackers, defensive counter-attackers, fast net players. The logic sounds sound, but it creates a new problem: pairs assembled from two different units take far longer to synchronise their movement rhythm.

The second is a fitness priority. The conditioning programme at Cipayung was pushed to six sessions a week, including two explosive strength sessions and one lactate threshold session. The direction is right, but it is a double-edged blade: Indonesian players are famous for explosive first games, and when they are dragged into a third game by East Asian opponents with better endurance bases, added load only helps if recovery is sufficient.

The third is data. For the first time, sparring sessions at Pelatnas are fully filmed and analysed rally by rally. I have seen three such internal reports on my most recent trip, and what caught my attention was what they count: the number of times a player loses the centre of the court after an opponent's smash. It is a very Southeast Asian metric, because the region's style revolves around holding the centre to counter quickly.

The worry is not that Indonesia is changing, but the speed of change. A development system needs roughly seven to eight years to produce an Olympic-class player. The Olympic cycle gives them four.

Men's doubles: stability is becoming a burden

Men's doubles is Indonesia's home discipline. It is also where the conflict between two Olympic cycles is clearest.

In recent years, Indonesia's leading pairs share one trait: they play a brand of badminton designed not to make mistakes, rather than to create pressure. In other words, they play to hold points, not to win them.

This works at Super 300 to Super 750 level, where technically weaker opponents will beat themselves. But in Olympic quarterfinals and semifinals, where the eight best pairs meet, the hold-the-point style is neutralised. East Asian and Taiwanese opponents in those matches tend to accept more errors in the first game in exchange for controlling the tempo in the second and third.

I rewatched footage of four Indonesian men's doubles matches at recent World Tour events and logged one pattern: in rallies lasting more than twelve shots, the win rate of Indonesian pairs drops noticeably compared with rallies under eight shots. An internal figure I heard from a sparring coach at Pelatnas is a gap of roughly fifteen to eighteen percentage points. That is the distance between a medal and a quarterfinal exit.

The cause lies in movement structure. Indonesia's traditional men's doubles style rests on clockwise rotation, where the front player always creates pressure and the rear player finishes. When opponents hit into the gap between the two, the rotation jams. And East Asian teams have studied that jam closely. They do not need to play better. They only need to hit the right spot.

This is why I believe Indonesia's personnel overhaul in men's doubles is necessary, but its execution is slow. Splitting into style-based units is theoretically correct, yet it breaks the synchrony that is a pair's greatest asset. A pair needs roughly eighteen to twenty-four months of continuous competition to build shared reflexes. Splitting units without a long-term pairing plan produces pairs that look good on paper.

Men's singles: the void after a golden generation

Indonesia's men's singles is the saddest story of the past decade, and also the least accurately told.

Jonatan Christie won the All England. Anthony Sinisuka Ginting won an Olympic bronze in Tokyo. Both are world-class players, and both have entered the phase every men's singles player enters: the phase where foot speed drops by half a step, and half a step is everything.

In men's singles, the gap between world No. 5 and world No. 15 is not in the smash. It is in the ability to re-establish the centre of the court after each shot. I measured by eye across three live matches: an elite player takes about 0.8 to 0.9 seconds to return to centre after a cross-court smash, while a player in decline takes about 1.1 to 1.2 seconds. Three tenths of a second, multiplied by roughly forty decisive rallies in a match, creates a gap that willpower cannot close.

Indonesia's problem is not the absence of young players. It is that those young players do not compete in a harsh enough environment.

I have followed Indonesia's domestic circuit for two seasons. A nineteen-year-old who wins the national title is typically pushed straight into Pelatnas and entered in regional Super 100 events. There he meets peers of similar level, wins about half his matches, then sits in qualifying draws of bigger events, playing two matches and going home.

Meanwhile, a Chinese or Japanese player of the same age may be placed in weekly training blocks with senior stars and given roughly twenty matches a year against stronger opponents. The difference is not talent. It is the number of hours spent facing elite badminton.

A badminton nation does not lack talent. It lacks the hours in which talent is forced to face badminton harder than itself.

Women's singles: Gregoria, Putri and the third-game problem

If Indonesian men's singles is struggling, women's singles offers the most positive signal — and the clearest illustration of how Southeast Asian thinking differs from East Asian thinking.

Gregoria Mariska Tunjung has been Indonesia's best women's singles player for years. She plays a very Indonesian game: smooth movement, varied shot-making, a preference for dragging opponents into rallies that require thought. She also carries the region's common ailment: the third game.

Women's singles has fundamentally changed over the past five years. An Se-young, the South Korean Olympic champion in Paris 2026, has reset the sport's standard. Her game is not built on smashes that lift crowds out of their seats. It is built on sending the shuttle over the net one more time than the opponent, at an intensity that makes rivals quit before the match ends.

Countering that requires two things. First, an aerobic base strong enough to sustain footwork for ninety minutes. Second, enough attacking sharpness to end rallies in seven shots or fewer, shortening the average rally length.

Southeast Asian women's singles players, in Indonesia and Vietnam alike, are usually strong on the second and weak on the first. It is a regional paradox: they have refined racket technique and the ability to change shuttle direction at the last moment, yet lack a conditioning system built by professional sports scientists.

I once watched a fitness test for a group of young women's players in Jakarta. The test was ten times forty metres with thirty seconds rest. After the seventh rep, an eighteen-year-old began to lose rhythm. The coach stopped the session, gave water, and told her to start over that afternoon. That handling came from admirable caution. But that caution, multiplied by four years, creates a gap no tournament can close.

Vietnam: from Nguyen Tien Minh to the post-2026 generation

In Vietnam, the story has a different shape.

Nguyen Tien Minh opened the door. He was Vietnam's first player to put the country on the world badminton map, reaching the world's top twenty and competing at four Olympic Games. For a country that never counted badminton among its priority sports, that was an almost entirely individual achievement.

But his legacy has a dark side rarely discussed: for more than a decade, Vietnamese badminton lacked a development system thick enough to create parallel pathways. When a country has only one forerunner, every resource — from international entries to training scholarships — flows in one direction.

In the past five years, that has changed. A next generation has emerged, with players exposed to international competition earlier. More importantly, a new layer of athletes capable of competing at World Tour level has appeared.

I have followed events featuring Vietnamese players across the last two seasons. Three observations stand out.

First, Vietnamese players at international events tend to be strong in basic technique and defence — a legacy of Vietnam's sports-centre training tradition, where technique is emphasised early.

Second, they are constrained in entries to Super 500 and above, because their ranking points are dragged down by competing less than regional rivals. It is a structural loop: fewer entries means fewer points, and fewer points means fewer entries.

Third, and most encouraging: Vietnamese players can now organise short training blocks with international partners, something Nguyen Tien Minh's generation almost never had.

Vietnam is at the stage Indonesia passed through twenty-five years ago: building foundations before building towers. The difference is that it can learn from its predecessor's mistakes — and it holds an advantage Indonesia does not: it is not bound by past Olympic medals.

The "one player, one team" model

There is a small detail from a regional badminton trip I have never forgotten.

On the evening before the first day of play, at a hotel near the arena, I met the support team of a Southeast Asian women's singles player. The team had four people: a coach, a fitness specialist, a physiotherapist, and an opponent analyst. Four people for one athlete.

Downstairs, another national delegation had seventeen athletes and three staff. Three people for seventeen athletes.

I do not tell this story to judge which approach is right. I tell it because it reveals something the rankings never display: in an individual sport, investment in support staff is not distributed evenly — and that distribution, more than anything, decides who can stay in the world's top twenty for years.

A player with a personal physiotherapist recovers roughly thirty percent faster after a long match, based on what I have observed of top players' schedules. Thirty percent, multiplied by twenty competition weeks a year, produces a different body after four years.

For Vietnamese and Indonesian players outside the leading group, the common model is still one coach wearing several hats: the person who teaches the shot, straps the ankle, and analyses video until midnight. That is a beautiful image for a documentary. It is not a beautiful image for sports science.

The physics of the shuttle: humidity, speed and arena roofs

There is a variable viewers rarely notice that decides matches more than form: the arena environment.

A badminton shuttle weighs about five grams, made from feathers fixed to a cork base. Its weight depends almost entirely on air humidity. In Jakarta, evening humidity often exceeds eighty percent. In a European arena in winter, it can fall below forty percent.

The difference sounds small. It is not.

In humid air, the shuttle travels slower, its falling trajectory shortens, and rallies grow longer. In dry air, it flies faster and rallies end sooner. A men's singles player built on endurance prefers humid air. A men's singles player built on speed and smashing prefers dry air.

This explains why Southeast Asian players often perform well at regional events and struggle at European events in winter. Not because they dislike the cold. Because their game is built on a tempo budget designed for humid conditions.

I verified this simply: I rewatched the matches of two Southeast Asian players at two different events, one regional and one European, against the same opponent. Average shots per rally were clearly higher at the regional event. And the Southeast Asians' win rate in long rallies was higher too.

A badminton nation that wants global success must train two versions of itself: one for humid air, one for dry air. Most Southeast Asian centres only train the first.

This is a gap money can close, and it does not take much money. A humidity-controlled training chamber covering two courts costs far less than signing a foreign player. But it demands a different way of thinking: treating environment as part of technique, not as logistics.

The BWF calendar: the points trap

The current World Tour structure has a feature that keeps smaller badminton nations permanently disadvantaged: ranking points are counted from a player's best twelve results over fifty-two weeks.

In theory, this is fair. In practice, it creates an allocation pressure only wealthy federations can absorb.

Take a specific example. A player ranked 35 who wants to enter the top 25 needs roughly four thousand more points. That equals a Super 500 semifinal, or a Super 100 title, or two Super 300 quarterfinals. Each option carries a different cost.

Winning a Super 100 sounds easiest, but requires entering five or six Super 100 events a year to have one chance at the title. Travel and accommodation for six such events, in cities like Guwahati, Odense or Huelva, can reach fifteen thousand US dollars. For an athlete without a major sponsorship, that is an investment they must balance alone.

Meanwhile, a player from a well-supported nation gets entries selected for maximum points and travels with an opponent-analysis team.

So the world badminton ranking does not only measure ability. It measures the cost-bearing capacity of the system behind the player.

This is why I keep telling younger colleagues in Vietnam and Indonesia: when writing about a player's ranking, include the context of how many events they played in twelve months. A No. 30 player with twenty events may be equal in ability to a No. 15 player with twelve. The difference is who has the budget to play more.

What the medal table does not say

Here I must say something I have held back for years, and which may displease some people in the industry.

Our way of judging Southeast Asian badminton nations is wrong at the root.

We measure by Olympic medals and titles at major events. That yardstick has a fatal flaw: it only records the results of roughly the world's top twenty players. The rest of the system — the people who maintain competitive density, who create sparring partners, who keep Super 100 events viable — never appears on a medal table.

And that rest is exactly what determines a badminton nation's long-term strength.

Try a different measure. Count the number of players each country has in the world's top 100. Count the number in the top 200. Count how many matches a country's young players play against foreign opponents in a year. These three indicators forecast the future far better than the number of Olympic medals won in the past four years.

When I applied this to the region, the results were surprising. Indonesia leads in squad breadth. Thailand leads in youth development quality, partly thanks to a strong private academy system. Malaysia has depth in doubles. Vietnam, despite a modest total of top-200 players, shows one notable trait: the share of young players improving their ranking each season is rising.

The nation with more players in the top 200 will have more chances in the next cycle, even if it won no Olympic medal in the past four years.

I do not write this to comfort anyone. I write it because I have watched countries make investment decisions based on a misread medal table. When a federation looks at that table and sees failure, it usually cuts funding to the grassroots system — precisely where money is most needed. That is a backwards response.

The economics of lower-tier events

If you want to know the future of Southeast Asian badminton, do not watch Super 1000 finals. Watch the calendar of International Challenge events.

This tier sits just below the World Tour, with total prize money usually between fifteen and twenty-five thousand US dollars. For players ranked 150, it is the main stage. For nations, it is the laboratory.

Hosting a successful International Challenge requires three things: a compliant arena, a trained officiating team, and two to three hundred registered players. Running such an event is the cheapest way for a country to build event-organising capability, and the cheapest way for its young players to face foreigners without flying out of the region.

In recent years, events at this tier in Southeast Asia have drawn stable participation — a signal far more important than a medal at a world championship. Each such event generates roughly twenty to thirty international matches for young players.

I once sat in a small arena, capacity about a thousand, watching a qualifying match between a nineteen-year-old local and a twenty-two-year-old visitor. The match lasted seventy minutes, three games. The local lost 21-19 in the decider. Afterwards he sat on the floor, took off his shoes, and stared into space. The coach said nothing for five minutes.

That was an Olympic medal of flesh and bone. There was simply nobody to award it.

Rules, cards and grey zones

In any discussion about badminton's future, one area is rarely mentioned: the rule system and how it is applied.

Badminton rules have changed at several important points over two decades, from adopting the twenty-one-point rally scoring system to rules on intervals between rallies. Every change created winners and losers.

The twenty-one-point rally system was designed to boost television appeal: every rally scores, matches are shorter, broadcasters can schedule more easily. But it also changed the sport's structure in a way few discuss: it reduced the value of reversing momentum.

Under the old scoring system, a trailing player could regain serve and rebuild the match slowly. Under the current system, every rally is a point, and a five-point gap can form within three minutes.

For Southeast Asian players — traditionally strong at building rallies and changing tactics mid-match — this system helps in terms of seizing chances and hurts in terms of controlling tempo. It is a shift that has not been fully analysed.

Then there is integrity. In recent years, international sports bodies have moved to tighten controls on betting and on conduct affecting match outcomes. But the speed of regulation always trails the speed of new betting formats, especially where online betting markets operate outside control.

This is not unique to badminton. But badminton has a vulnerability that team sports do not: one individual can influence a match result through small decisions almost indistinguishable from technical error. A shot out at 18-19 can be a mistake, or it can be something else. In team sports, fixing a result usually takes several people. In badminton, sometimes it takes one.

Regulations only have value when processing time is shorter than market development time. In badminton, that gap is widening, not closing.

Takeaway

The next four-year cycle for Southeast Asian badminton will be shaped by three variables, and none of them sits on court.

The first is how many World Tour entries players from the region secure over the next two seasons. If that number rises, the future has a floor. If it stalls, every restructuring plan is just a nice presentation.

The second is the pace of building sports-science infrastructure — not bigger gyms, but humidity-controlled training chambers, rally-by-rally video analysis, and enough physiotherapists that every leading player has one companion through the season.

The third, and the one I care about most, is whether countries in the region accept measuring themselves by the number of players in the top 200, or keep measuring by medals.

I returned to Cipayung that afternoon. The shoes were still there, toes inward, the worn right sole dusted grey. The player had gone home. The hall was dark except for one lit corridor.

A rally holds three truths: the player's, the umpire's, and the crowd's. But a badminton nation holds thousands of truths, and most are never recorded. The person holding the microphone does not judge; he only shines a light on the rally — and sometimes that light must fall on places where the lights were switched off long ago.

The next match will come on some date in the BWF calendar I have circled in red. What I will watch is not who wins. What I will watch is how many new names appear in the qualifying draw — because that is the signal telling us what the next four years will look like.

I stepped down onto court to pick up the microphone, but I have never left the court.
