Mathematics and environmental science may help explain why some sports records fall rapidly while others endure for decades. As Swedish pole vaulter Armand Duplantis continues to redefine human limits, experts suggest that performance records—whether in sport or climate—follow predictable statistical patterns that slow over time.

Duplantis and the Quest for Athletic Perfection

At the 2025 World Athletics Championships in Tokyo, Swedish athlete Armand “Mondo” Duplantis once again captivated the crowd. The reigning pole vault champion sprinted down the runway, planted his pole, and soared to a new height of 6.3 meters (20.6 feet)—his 14th world record and third consecutive world title.

Duplantis’s feat underscores how technological and physiological advances continue to shape modern athletics. Improvements in training, diet, biomechanics, and equipment have spurred record-breaking performances across several disciplines. In events such as pole vaulting and cycling, even minor technical innovations can lead to dramatic gains.

Yet not all sports follow this pattern. The men’s long jump record—set by Mike Powell in 1991 at 8.95 meters (29 feet 4 inches)—has remained untouched for more than three decades. Some analysts believe the event may have reached its physical and biomechanical limits, where external conditions such as wind, rest, or reaction timing determine marginal performance differences.

The Mathematical Logic of Records

Scientists describe this kind of plateau as a “stationary system”—one in which average performance remains stable over time. To understand how often new records might occur in such systems, mathematicians turn to examples from natural processes, including pre-industrial climate patterns and annual rainfall data.

Imagine measuring yearly rainfall across hundreds of cities. The first year automatically sets a record. In the second year, roughly half the cities surpass the previous total. By the third year, only one-third do. Mathematically, the expected number of records over time follows a sequence known as the harmonic series: 1 + ½ + ⅓ + ¼ + … + 1/n.

While the added terms become smaller, the sum continues to grow indefinitely—a concept known in mathematics as divergence. This explains why even in a stationary system, records can still occur, though increasingly infrequently. Statistically, after 100 years, only around five new records might be expected; after 1,000 years, perhaps seven.

This model helps scientists assess whether systems—from sports to climate—are stationary or changing. If records occur more frequently than mathematics predicts, it signals that something fundamental in the system is shifting.

Climate Data and the Record Ratio

Climate research provides a striking example of how record frequency reveals systemic change. According to the World Meteorological Organization (WMO), the rate of record-breaking heat events has surged in recent decades—far outpacing what would be expected in a stationary climate.

Scientists measure this through a metric called the record ratio, which compares the actual frequency of records to the predicted frequency. In the last 15 years, the ratio for cold events has fallen below 0.5, meaning cold records are now broken half as often as expected. Conversely, the hot record ratio climbed above 6.0 in 2024, the warmest year on record, suggesting heat extremes are occurring six times more often than they would in a stable system.

This statistical imbalance underscores the accelerating pace of global warming, driven largely by human-induced greenhouse gas emissions.

Has Human Performance Reached Its Peak?

Sports scientists have debated whether human athletic potential is also approaching a stationary limit. Studies examining performance data across track and field events indicate that many disciplines may be nearing physiological ceilings. If true, world records will become increasingly rare, mirroring the slowdown seen in mathematical models.

However, others argue that innovation and individual brilliance continue to expand what is possible. Duplantis’s repeated breakthroughs suggest the pole vault remains a dynamic event, while long jump results imply stagnation. Similarly, swimming has seen fluctuating record frequencies—accelerated by the introduction of polyurethane “super-suits” in 2008–2009, which were later banned for providing unfair advantages. Since then, improvements in technique and pool design have gradually rekindled record-setting progress.

Extraordinary Athletes and Changing Conditions

In some cases, exceptional athletes redefine the boundaries of sport. American swimmer Katie Ledecky has shattered 16 world records, including a recent benchmark in the 800-meter freestyle. These individual achievements highlight how rare combinations of physiology, training, and mental focus can overcome apparent physical limits.

Yet environmental factors are becoming increasingly influential. The 2025 World Athletics Championships in Tokyo were held under intense heat and humidity, prompting World Athletics President Sebastian Coe to acknowledge that climate change could force the organization to reconsider the tradition of summer events. Only one world record—Duplantis’s—was set during the competition, and surveys found that three-quarters of athletes reported heat-related impacts on performance and health.

The Mathematics of Progress

Mathematics teaches that while records can always be broken, their frequency naturally declines as systems mature—whether that system is the climate, human physiology, or athletic technique. When change accelerates, as in global warming, records fall faster; when it slows, as in elite human performance, breakthroughs become rarer.

For now, Duplantis and athletes like Ledecky remind the world that while mathematics can describe the limits of possibility, extraordinary human effort can still redefine them.

Kokichi Akuzawa, a 102-year-old mountaineer from Japan, has officially become the oldest person to reach the summit of Mount Fuji. His remarkable achievement was recognized by Guinness World Records after he successfully completed the climb in early August 2025.

Despite health challenges and the immense difficulty of the climb, Akuzawa pushed through with encouragement from his family and friends. His story reflects both resilience and the power of community support in overcoming extraordinary obstacles.

The Climb to the Summit

Akuzawa began his ascent on August 3 with a climbing party that included his 70-year-old daughter Motoe, his granddaughter, her husband, and several friends from a local mountaineering club. Together, they camped along the trail for two nights before making their final push to the summit on August 5.

Standing at 3,776 meters (12,388 feet), Mount Fuji is Japan’s tallest and most iconic peak. While the mountain is not considered technically difficult to climb, the altitude and physical demands make it a formidable challenge—especially for someone of Akuzawa’s age.

Speaking with The Associated Press, Akuzawa admitted the journey tested his limits:

“I was really tempted to give up halfway through,” he said. “Reaching the summit was tough, but my friends encouraged me, and it turned out well. I managed to get through it because so many people supported me.”

A Veteran of Mount Fuji

This was not Akuzawa’s first record-setting climb. In 2019, at age 96, he became the oldest person to reach the summit of Mount Fuji, a record he has now surpassed six years later.

In the years between climbs, Akuzawa faced significant health challenges, including heart issues, shingles, and even injuries from a fall. Yet his determination remained undeterred. For three months before the latest ascent, he trained rigorously—waking at 5 a.m. for long walks and climbing smaller peaks near his home in Gunma Prefecture.

His preparation routine included weekly climbs in the mountains of Nagano, which helped build endurance ahead of the historic attempt.

A Lifetime Connected to the Mountains

Akuzawa’s love for mountaineering began 88 years ago, when he first took to the hills as a teenager. Now living in Maebashi, northwest of Tokyo, he is surrounded by paintings and photos of the mountains he has conquered. For him, climbing has always been about more than reaching the peak—it has been about friendship and connection.

“I climb because I like it,” he said. “It’s easy to make friends on the mountain.”

Over the course of his long life, Akuzawa worked as an engine design engineer and later as a livestock artificial inseminator, a career he pursued until the age of 85. Yet mountaineering remained his lifelong passion.

Struggles and Triumphs at 102

Although Mount Fuji has been part of his life for decades, this year’s climb was by far the most demanding.

“Mount Fuji isn’t a difficult mountain, but this time was harder than six years ago,” Akuzawa admitted. “Harder than any mountain before. I’ve never felt this weak. I didn’t have pain, but I kept wondering why I was so slow, why I had no stamina. I’d long since passed my physical limit, and it was only thanks to everyone else’s strength that I made it.”

His family, especially his daughters Yukiko and Motoe, played a crucial role in helping him complete the journey. Because of his hearing loss, Yukiko often repeated questions to him during interviews, underscoring the teamwork that made the climb possible.

Looking Ahead: Painting Instead of Climbing

When asked if he plans to climb Mount Fuji again, Akuzawa responded with a mix of humor and realism:

“I’d love to keep climbing forever, but I guess I can’t anymore. Now I’m at the level of Mount Akagi,” he said, referring to a nearby peak just half the height of Fuji.

Instead of setting new climbing records, Akuzawa now devotes his mornings to volunteering at a senior care center and teaching painting at his home studio. His passion for art mirrors his mountaineering spirit, offering him a new way to channel creativity and discipline.

“People who climb mountains, people who paint—if they can create something whole on that path, that’s the most fulfilling thing,” he said.

His daughters have already asked him to capture Mount Fuji at sunrise on canvas, adding to the collection of mountain scenes that line the walls of his home. For Akuzawa, these paintings may serve as lasting tributes to the mountains that shaped his extraordinary life.

A Legacy of Inspiration

Kokichi Akuzawa’s journey to the top of Mount Fuji at 102 is more than a record-breaking feat. It is a story of perseverance, family support, and the enduring spirit of adventure.

As he transitions from climbing peaks to painting them, Akuzawa continues to inspire mountaineers, seniors, and dreamers around the world—proving that determination and passion can carry us to great heights, no matter our age.
