What's not represented

  • · Youth fencers managing early-career overuse injuries

Why this matters

Fencing is often perceived as a low-impact sport, but the explosive directional changes exact a heavy toll on athletes' knees, ankles, and nerves. How these top-ranked fencers manage their recoveries will directly shape the podium at the upcoming Hong Kong World Championships.

Key points

  • Japan's Koki Kano has returned to form with a gold at the Medellín Grand Prix after a difficult, injury-plagued start to the season.
  • China's Sun Yiwen has adapted her fencing style to manage severe nerve damage sustained after the Tokyo Olympics.
  • American Miles Chamley-Watson highlighted the prevalence of ACL and MCL tears in the sport.
  • The FIE is launching the Fencing Injury Surveillance System (FISS) to better track and prevent athlete injuries globally.

Consecutive podium misses for Kano before his recent gold

The road to the 2026 FIE World Championships in Hong Kong is paved with ice packs, physical therapy sessions, and meticulous load management. For the world's elite fencers, the battle against their own bodies is often more grueling than the opponent standing across the piste.

Japan's Koki Kano, the reigning Olympic and World Champion in men's epee, recently endured a surprisingly difficult stretch. Dealing with the accumulated physical toll of his aggressive, high-mobility style, Kano failed to reach the podium in his first six events of the 2025–2026 season.[1]

However, Kano has signaled a triumphant return to form just in time for the summer championships. Two weeks ago, he captured gold at the Medellín Grand Prix, securing a decisive 15-9 victory over Italy's Matteo Galassi and proving his fitness is back at a championship level.[1]

Recent medical data highlights the prevalence of lower-body overuse injuries in the sport.

Meanwhile, China's Olympic epee champion Sun Yiwen has been fighting a much longer war of attrition. Following a severe meniscus tear sustained during the Tokyo Games, Sun developed debilitating entrapment neuropathies in her waist and coccyx.[2]

The nerve damage was so severe that even a small jump caused radiating pain, forcing the veteran to entirely rebuild her footwork. Rather than relying on explosive leaping, Sun has adapted her game to focus on tactical precision, proving that elite fencers can evolve their style to accommodate their physical realities.[2]

In men's foil, American star Miles Chamley-Watson has been highly vocal about the hidden brutality of the sport. Known for his towering 6'5" frame and acrobatic strikes, Chamley-Watson recently suffered a direct foil strike to the kneecap, adding to a career history of broken fingers and ligament strains.

Chamley-Watson notes that anterior cruciate ligament (ACL) and medial collateral ligament (MCL) tears are incredibly common due to the violent, instantaneous changes of direction required on the strip, actively dispelling the pop-culture myth of fencing as a "light tap" activity.

Hungary's Gergely Siklosi, a dominant force in men's epee, has taken a proactive approach to injury prevention. After battling a lingering foot injury and undergoing hand surgery in recent years, Siklosi now mandates strict rest periods—including three-week total shutdowns—to prevent the overuse injuries that plague the circuit.[3]

A 2026 prospective cohort study published by the National Institutes of Health confirms these athletes' experiences. The research reveals that elite fencers suffer 3.22 injuries per 1,000 training hours, with chronic overuse injuries vastly outnumbering acute trauma.[4]

The study found that nearly 58 percent of all fencing injuries affect the lower extremities, with saber fencers exhibiting the highest overall injury incidence due to the weapon's rapid, explosive footwork demands.[4]

Recognizing this growing physical toll, the International Fencing Federation (FIE) is launching a major safety initiative. On July 23, 2026, the FIE will host a dedicated Sports Medicine Conference alongside the Hong Kong World Championships.[5]

The conference will officially roll out the Fencing Injury Surveillance System (FISS), aiming to standardize global data collection on training loads, concussion management, and biomechanical stress. As Kano, Sun, and Chamley-Watson finalize their preparations, their resilience highlights the evolving nature of modern fencing—a sport where medical science is now just as critical as blade work.[5]

Viewpoints in depth

Sports Medicine Researchers

Focuses on quantifying the biomechanical toll of the sport and developing data-driven prevention strategies.

Medical professionals studying the sport emphasize that fencing is far more physically demanding than its elegant reputation suggests. With 3.22 injuries per 1,000 training hours, researchers point out that the repetitive, asymmetrical lunging and rapid directional changes place immense stress on the lower extremities. They advocate for the widespread adoption of tools like the Fencing Injury Surveillance System (FISS) to gather actionable data on training loads and biomechanical wear.

Veteran Athletes

Emphasizes the grueling reality of the competitive calendar and the necessity of load management and tactical adaptation.

For fencers who have spent a decade or more on the international circuit, managing the body becomes just as important as mastering the blade. Veterans like Gergely Siklosi and Sun Yiwen argue that the packed global calendar forces athletes to either adapt their tactical approach to protect injured joints or mandate their own strict rest periods. They view injury not just as a setback, but as a permanent variable that requires a constant evolution of their fencing style.

Fencing Governing Bodies

Aims to balance a demanding global competition schedule with new institutional safety protocols and injury tracking.

The International Fencing Federation (FIE) acknowledges the rising physical toll on its top athletes and is shifting its focus toward institutional prevention. By organizing dedicated sports medicine conferences and rolling out standardized injury tracking systems, governing bodies are attempting to create a safer competitive environment without compromising the rigorous qualification pathways required for the World Championships and Olympic Games.

What we don't know

  • Whether Sun Yiwen's adapted, low-impact footwork will be enough to secure a podium finish against fully healthy opponents in Hong Kong.
  • How quickly the new Fencing Injury Surveillance System (FISS) will lead to tangible changes in training guidelines or competition schedules.

Key terms

Entrapment Neuropathy
A medical condition caused by direct pressure on a single nerve, leading to pain, tingling, or weakness, which Sun Yiwen has battled in her waist and coccyx.
Overuse Injury
Tissue damage that results from repetitive demand over the course of time, rather than an acute, single traumatic event.
Piste
The official term for the playing surface or strip where a fencing bout takes place.

Frequently asked

What is the most common type of fencing injury?

Overuse injuries to the lower extremities are the most common, accounting for nearly 58 percent of all fencing injuries according to recent NIH data.

Which fencing weapon has the highest injury rate?

Saber fencers experience the highest incidence of injury, largely due to the explosive and rapid footwork required by the weapon's rules.

What is the Fencing Injury Surveillance System (FISS)?

FISS is a new global data collection initiative launched by the FIE to track training loads, biomechanical stress, and injuries to better protect athletes.
