When Daria Kasatkina cut short her 2025 season early in October, the ex-top ten player explained how she had "encountered a barrier."

"The calendar is overwhelming. My mental and emotional state is frayed, and, sadly, I'm not alone," she expressed.

Elina Svitolina of Ukraine, a double Wimbledon semi-final participant, had earlier announced she was not in "the right headspace" to persist, while current Grand Slam champions Iga Swiatek and Carlos Alcaraz also believe the calendar is too long.

This subject continues to be debated as the world's leading tennis players reconvene in Australia for the start of the 2026 season.

A marginally increased off-season than 2025 has been received well. Nonetheless, a few weeks is not seen as adequate time for thorough recovery before work commences for an 11-month campaign regarded as among the most demanding 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).

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

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

So what actions are being taken and what next actions could be enacted?

Condensing the Tour Schedule

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

The WTA Tour season finished two weeks earlier when the season-ending championships concluded in early November. The International Tennis Federation moved the Billie Jean King Cup Finals forward to September to alleviate scheduling concerns.

The men's tour states it does not take the concerns of the players "without seriousness," while the WTA Tour says player welfare will "always remain a top priority."

That did not appease the PTPA, which began legal action against the men's and women's tours in March, citing "anti-competitive practices and a blatant disregard for player welfare."

Overhauling the calendar is an obvious solution but cannot be achieved easily given the complex nature of tennis governance, where the four Grand Slams, ATP, WTA, and ITF each have controlling interests.

"It is crucial to evaluate whether we can reclaim 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," said Dr. Sikka.

Former world number one Andy Roddick, a long-time advocate for change, says the season should not go past 1 November.

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

"One point that often gets overlooked: players determine their own playing calendar," commented ATP chairman Andrea Gaudenzi.

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

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

"In my view, athletes are more psychologically drained and exhausted because they're away from home for extended periods," stated Britain's former men's world number one, Andy Murray.

Alongside mental burnout, there are apprehensions about the growing physical demands.

Players suffer more severe upper-body injuries in particular times of the year, according to PTPA research.

The organization says these "foreseeable patterns" are down to the seasonal itinerary and the transitions between court surfaces.

Minimizing Midnight Matches & Uniform Balls

When a notable match at the Australian Open ended in the middle of the night in 2023, it was expected to drive reform.

In 2024, the tours introduced a new rule stopping matches beginning past 11pm.

But there have continued to be instances of matches finishing well past midnight - which medical experts cannot be allowed to be "romanticised".

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

"There are press obligations, recovery sessions, and physio appointments. Your day doesn't finish until much later.

"Your body, brain and nerves don't have chance to recover. This is a unique demand in the sporting world."

A lack of standardization in tournament equipment - leading to changes in weight and pace - has been cited as a source of a rise in upper body injuries.

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

A former US Open champion, who stepped away last year with an persistent wrist issue, argues tournaments in the same circuit should use one type of ball.

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

The tours adopted a more unified ball-approval process during 2025 and anticipate "total consistency" in the coming years.

Learn from NFL & Protect Young Players

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

Using data-led analysis, the NFL mandated consistent playing surfaces and improved helmet technology to minimize the risk of injury.

"The league has altered its regulations using concrete research," 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 ensuring star athletes are available.

"They are investing heavily in their stated goals by protecting athletes and devoting significant resources – that model is the benchmark."

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

Some retired players believe the load put on the upper body of tennis players from a tender age is a key element in their injuries later on.

"We pick up a racket as kids 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."

Players 'Motivated' for Change - What Do They Want?

An growing group of players are becoming vocal about the demands placed on them.

Current world number ones are among a collection of elite athletes ramping up pressure on the Grand Slams with calls for a increased portion of tournament income, as well as meaningful consultation about the calendar extent, longer competitions and match timing.

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

Sympathy can be in short supply, though, given top players occasionally sign up for lucrative non-tour contests.

One Grand Slam champion from Britain says the grind is a "difficulty" but thinks top players "criticizing the calendar" is not a good look.
