When Information is Scarce: Lessons from the Gaps in Vietnamese Sports

The training ground was empty of spectators, but the pulse of the ball still echoed.

I remember an afternoon in March 2026, when I was still a rookie reporter at Busan IPark. It was raining heavily, and the Gijang training ground was left with only me and an old photographer. He told me: "If you don't have information, don't write. If you have information but not enough, stay silent and observe more." That sentence has stayed with me throughout my 16-year career.

Today, I received a technical analysis — but it was empty. No content, no data, no characters, no sources. A long report saying "insufficient information for analysis." And that made me think about Vietnamese sports.

How many times have we made judgments about a match, a player, a team without having enough information? How many times have we rushed to conclusions based on emotion rather than data?

Information gaps — the chronic disease of Vietnamese sports

From Busan looking toward Vietnam, I see a paradox. We have exceptional sporting talents, but the information and data systems surrounding them are incredibly poor.

Look at Vietnamese football. Every season, we have hundreds of matches in V-League, First Division, National Cup. But how much tactical data is systematically collected? How much information about fitness, injuries, and player psychology is properly documented?

I once worked with a Korean scout who specialized in following Vietnamese players. He had a 300-page notebook, meticulously recording every training session, every touch of the ball, every expression on players' faces. "Vietnamese people have talent," he said, "but you don't know how to preserve information. Each season passes, and you lose a part of your memory."

That sentence has haunted me ever since.

When there's no data, emotions take over

One of the biggest problems in Vietnamese sports media is the lack of data leading to emotions and prejudices overwhelming analysis.

I remember the match between U23 Vietnam and U23 South Korea at the 2026 ASIAD. After a 1-3 loss, countless articles wrote about "the weakness of the defense," "the goalkeeper's mistake," "the coach's lack of courage." But no one analyzed that U23 Vietnam had played 120 minutes in the quarterfinal just three days earlier, that the players' fitness had dropped below acceptable thresholds, that the opponent had a payroll 20 times larger and superior nutrition programs.

No fitness data, no workload information, no recovery metrics — and so we blamed individuals instead of understanding the system.

Lessons from Korea: A culture of data

Living in Korea for 8 years, I've witnessed how this country builds a sports ecosystem based on data. Every K-League player has a detailed electronic profile: heart rate during training, distance covered in matches, pass accuracy, sprint counts, recovery time after injuries.

At Busan IPark, I once saw the head coach call a young player into the meeting room and say: "You've run 1.2 km less than the team average in the last three matches. This is from GPS tracking data. Do you want to explain?"

That player couldn't lie. Data doesn't lie.

In Vietnam, how many clubs use GPS tracking? How many teams have data analysts? How many sports journalists know how to read and analyze statistics?

The consequences of information scarcity

Information scarcity doesn't just affect media. It directly impacts the development of athletes and teams.

I witnessed a young Vietnamese talent being rejected from a Korean club's academy simply because he lacked a complete medical record. He had an ankle injury at age 15, but no one documented it. When he arrived in Korea, the team doctor discovered scar tissue in the ligament and concluded: "High risk of recurrence, not eligible for contract."

A talent lost just because of a missing medical document.

A story from Vietnamese martial arts

As a reporter covering martial arts, I see this problem even more clearly. Vietnamese martial arts have thousands of years of history, but information about fighters, techniques, and matches is scattered and unsystematic.

I once interviewed a Vietnamese boxer competing in Korea. He said: "In Vietnam, I trained by feel. In Korea, the coach made me watch recordings of every match, analyze every punch, every movement. Only then did I know where I was wrong."

No data, no video analysis, no metrics — Vietnamese fighters train in the dark. They don't know their strengths, their weaknesses, what needs improvement.

Solutions: Building a sports information system

I'm not pessimistic. I see positive signals.

Some V-League clubs have started investing in technology. The Vietnam Football Federation is building a player database. Some young journalists have learned to use data in their writing.

But it's still too slow.

I propose three specific solutions:

One: Establish a national sports data center that stores information about all athletes from youth to professional levels. Each athlete has a unique identifier with medical records, competition achievements, and fitness metrics.

Two: Train sports journalists in data analysis skills. A good journalist not only knows how to write, but also how to read numbers, ask questions based on data, and verify information authenticity.

Three: Encourage clubs to invest in tracking and analysis technology. GPS, slow-motion cameras, tactical analysis software — these tools are no longer too expensive, and their benefits are invaluable.

Conclusion: From gaps to light

I'm sitting in a small cafe in Busan, looking out at the sea. My laptop screen shows an empty analysis — a reminder that in sports, as in life, information is the most precious thing.

From Busan to Vietnam, from empty training grounds to stadiums full of fans, I've learned that a season never ends with the final match. It ends when we have enough information to understand what happened.

Players run on the field, I keep the rhythm of every step — the memory of an observer who never sits still. And I believe that one day, Vietnamese sports will have enough data to no longer have to judge in the dark.

When the stands are empty, I hear the players' breathing more clearly than ever — that's a sound no television can capture. And that's also the most precious data we are losing.

I am the beat keeper — not for the match, but for the stories on the sidelines that bleed every minute. And today's story is about the lack of information in Vietnamese sports.

Hopefully, one day soon, we won't have to write articles like this anymore.
