When Daria Kasatkina concluded her 2025 season ahead of schedule in October, the former world number eight described how she had "reached her limit."

"The calendar is overwhelming. Mentally and emotionally I'm at breaking point, and, regrettably, I'm not alone," she wrote.

The Ukrainian athlete Elina Svitolina, a former Wimbledon final four contender, had previously announced she was not in "the psychological condition" to persist, while current Grand Slam champions Iga Swiatek and Carlos Alcaraz also are convinced the calendar is overly extended.

This issue is still being argued as the world's top tennis players assemble once more in Australia for the start of the 2026 season.

A somewhat extended off-season than 2025 has been welcomed. Nonetheless, a handful of weeks is not regarded as enough time for adequate recuperation before training starts for an 11-month campaign considered among the most grueling in professional sport.

"Tennis places greater strain on athletes now than it ever has," stated Dr. Robby Sikka, chief medical officer at the Professional Tennis Players' Association (PTPA).

"Points and games are more extended, players are faster, they're hitting the ball harder.

"We have a duty to safeguard our athletes and give them a more manageable sport."

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

Condensing the Tour Schedule

The 2025 season covered 47 weeks for many men on tour, beginning with the United Cup team event in late December 2024 and ending with the Davis Cup final in late November.

The women's season finished two weeks earlier when the WTA Finals wrapped up in early November. The International Tennis Federation moved the Billie Jean King Cup Finals forward to September to help combat scheduling concerns.

The men's tour states it does not take the concerns of the players "without seriousness," while WTA leadership notes player welfare will "perpetually be the highest focus."

That failed to satisfy the PTPA, which began legal action against the men's and women's tours in March, citing "unfair practices and a clear neglect of athlete well-being."

Restructuring the calendar is an clear answer but cannot be achieved easily given the intricate web of tennis governance, where the four Grand Slams, ATP, WTA, and ITF each have significant influence.

"We need to think about whether we can create more time at the end of the year for an extended off season, or can we create space during the season so there is a short hiatus," added Dr. Sikka.

Former world number one Andy Roddick, a vocal proponent of reform, says the season should not go past 1 November.

The ATP Tour has reduced the number of events which are included in the rankings for 2026, which it believes will reduce "the cumulative strain" on the players.

"A factor frequently ignored: players choose their own schedules," remarked ATP chairman Andrea Gaudenzi.

"Such autonomy is uncommon in elite athletics. But with that comes obligation - knowing when to push and when to recover."

Prolonging several compulsory competitions across a fortnight - creating so-called 'super weeks' - has also been questioned.

"In my view, athletes are more psychologically drained and exhausted because they're being on the road longer," opined Britain's former men's world number one, Andy Murray.

Alongside mental burnout, there are concerns about the increased physical demands.

Players experience a higher rate of upper-body injuries in particular times of the year, according to available data.

The organization says these "predictable clusters" are down to the seasonal itinerary and the turnarounds between court surfaces.

Reducing Late Finishes & Standardizing Equipment

When a notable match at the Australian Open concluded in the wee hours in 2023, it seemed set to trigger adjustments.

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

But there have persisted instances of matches ending deep into the night - which medical experts cannot be allowed to be "romanticised".

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

"You have to do media, recover, work with the physiotherapist. Your day doesn't finish until much later.

"There is insufficient opportunity for the body and mind to heal. There is no other sport which mandates that."

Different tournaments playing with different balls - leading to changes in feel and performance - has been identified as a source of a rise in upper body injuries.

"I've had a lot of injuries in my arm, my shoulder, my wrist," stated one top British player, "and I'm seeing more and more of these injuries across the tours."

A former US Open champion, who ended his career last year with an persistent wrist issue, argues tournaments in the same swing should use one standard ball.

"This should be a straightforward solution - the same ball for clay, the same for hard and the same for grass. That would be incredibly useful to the players," he said.

The tours began using a more standardized equipment policy during 2025 and expect "complete uniformity" in the coming years.

Take Lessons from the NFL & Shield Developing Athletes

Medical researchers believe tennis must learn from how American team sports use data to guide the health of its stars.

Using data-led analysis, the NFL demanded consistent playing surfaces and improved helmet technology to reduce 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.

"Their commercial success has soared because their games are so competitive and they're maintaining a healthy roster.

"Their financial commitment matches their rhetoric by protecting athletes and investing hugely – that model is the benchmark."

Other leagues have enacted regulations aimed at protecting pitchers, limiting their throws at the professional level and putting limits for young players.

Some retired players believe the stress 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 iterations of our groundstrokes," said the former champion.

"At some point it goes on the wrist. 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 rising contingent of players are becoming vocal about the demands placed on them.

Current world number ones are among a group of stars ramping up pressure on the Grand Slams with calls for a increased portion of tournament income, as well as genuine dialogue 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 upcoming tour.

Support is not always forthcoming, though, given top players occasionally sign up for lucrative showcase matches.

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