When Daria Kasatkina cut short her 2025 season ahead of schedule in October, the former world number eight detailed how she had "hit a wall."

"The itinerary is excessive. Mentally and emotionally I'm at breaking point, and, unfortunately, I'm not alone," she wrote.

The Ukrainian athlete Elina Svitolina, a two-time Wimbledon semi-finalist, had already declared she was not in "the mental space" to persist, while sitting Grand Slam champions Iga Swiatek and Carlos Alcaraz furthermore are convinced the calendar is excessively lengthy.

The topic is still being argued as the world's leading tennis players gather again in Australia for the commencement of the 2026 season.

A somewhat extended off-season than 2025 has been welcomed. However, a handful of weeks is not considered sufficient time for adequate recuperation before work commences for an season lasting nearly a year seen as among the most grueling in professional sport.

"The demands of tennis are harder than ever before," said Dr. Robby Sikka, head of medicine at the Professional Tennis Players' Association (PTPA).

"Matches and rallies are longer, players are faster, they're hitting the ball harder.

"It is our obligation to shield the competitors and give them a more sustainable sport."

So what is being done and what next actions could be taken?

Condensing the Tour Schedule

The 2025 season covered 47 weeks for many male competitors, commencing with the United Cup team event in late December 2024 and ending with the Davis Cup final in late November.

The women's circuit finished two weeks earlier when the season-ending championships wrapped up in early November. The governing body moved the Billie Jean King Cup Finals forward to September to help combat scheduling concerns.

ATP officials claim it does not take the concerns of the players "casually," while the women's tour asserts player welfare will "perpetually be the highest focus."

That did not appease the PTPA, which commenced proceedings against the men's and women's tours in March, citing "restrictive policies and an obvious indifference to player health."

Revamping the calendar is an clear answer but cannot be implemented readily given the intricate web of tennis governance, where the four Grand Slams, ATP, WTA, and ITF each have major stakes.

"We need to think about whether we can buy back time at the end of the year for an extended off season, or can we allow for a pause during the season so there is a mini-break," noted Dr. Sikka.

Former world number one Andy Roddick, a consistent campaigner for adjustments, says the season should not go past 1 November.

The ATP Tour has decreased the number of events which factor into the rankings for 2026, which it is confident will diminish "overall demands" on the players.

"A factor frequently ignored: players determine their own playing calendar," commented ATP chairman Andrea Gaudenzi.

"Such autonomy is uncommon in elite athletics. But with that comes accountability - recognizing the right time to play and the right time to heal."

Extending several compulsory competitions across a fortnight - creating so-called 'extended events' - has also been questioned.

"I believe competitors are more worn out mentally and physically because they're spending more days away," opined Britain's former men's world number one, Andy Murray.

In addition to mental burnout, there are concerns about the rising physical demands.

Players suffer more severe upper-body injuries in particular times of the year, according to player association statistics.

The organization says these "predictable clusters" are down to the structure of the calendar and the switches in court surfaces.

Reducing Late Finishes & Standardizing Equipment

When a memorable contest at the Australian Open ended in the early hours in 2023, it was expected to drive reform.

In 2024, the tours implemented a new rule prohibiting matches commencing later than 11pm.

But there have persisted instances of matches concluding long after midnight - which medical experts insist.

"When you are done playing you just don't go home," added Dr. Sikka.

"Media interviews, rehabilitation, and treatment are required. Your day extends well beyond the match.

"There is insufficient opportunity for the body and mind to heal. No other major sport imposes such conditions."

The use of varying balls at different events - leading to changes in weight and pace - has been cited as a source of a rise in upper body injuries.

"My career has been plagued by injuries to the arm and wrist," commented one top British player, "and such ailments are increasingly prevalent among peers."

A former US Open champion, who ended his career last year with an chronic wrist problem, believes tournaments in the same swing should use one uniform ball.

"It shouldn't be too difficult - the same ball for clay, the same for hard and the same for grass. That would be really helpful to the players," he said.

The tours adopted a more centralized ball-selection system during 2025 and project "total consistency" in the coming years.

Take Lessons from the NFL & Shield Developing Athletes

Medical researchers believe tennis must take cues from how American team sports use data to inform the health of its stars.

Following data-led analysis, the NFL demanded consistent playing surfaces and advanced helmet technology to lessen the risk of injury.

"American football has implemented numerous reforms driven by data," said an analytics expert whose firm provides data to monitor player welfare.

"The financial returns have increased dramatically because their games are so competitive and they're keeping players out on the field.

"They are investing heavily in their stated goals by protecting athletes and investing hugely – that model is the exemplar."

Other leagues have enacted regulations aimed at protecting specific positions, limiting their exertion at the professional level and putting guidelines for juniors.

Some retired players believe the load put on the upper body of tennis players from a young age is a major contributor in their injuries later on.

"Training begins in childhood and have so many repetitions of our groundstrokes," said the former champion.

"Over time, the wrist suffers the consequences. Way more players have problems with the wrist. I think the problem is the many, many repetitions."

Competitors Seek Adjustments - What Are the Key Issues?

An increasing number of players are becoming vocal about the demands placed on them.

Current world number ones are among a collection of elite athletes increasing demands on the Grand Slams with calls for a increased portion of tournament income, as well as substantive discussions about the calendar extent, extended events and scheduling.

Last year, a top-ten American player said it was "unreasonable" he was only able to take one week off before the new season.

Public understanding may be limited, though, given top players occasionally sign up for lucrative non-tour contests.

One Grand Slam champion from Britain says the daily routine is a "test" but thinks top players "complaining about the calendar" is not a good look.
