At the point when Daria Kasatkina ended her 2025 season ahead of schedule in October, the ex-top ten player detailed how she had "encountered a barrier."

"The itinerary is excessive. My mental and emotional state is frayed, and, unfortunately, I'm not alone," she stated.

Elina Svitolina of Ukraine, a two-time Wimbledon semi-finalist, had already revealed she was not in "the mental space" to continue, while sitting Grand Slam champions Iga Swiatek and Carlos Alcaraz also think the calendar is overly extended.

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

A slightly longer off-season than 2025 has been welcomed. However, a few weeks is not considered sufficient time for proper rest before preparations begin for an 11-month campaign seen as among the most grueling in professional sport.

"Tennis places greater strain on athletes now than it ever has," commented Dr. Robby Sikka, head of medicine at the Professional Tennis Players' Association (PTPA).

"The duration of play has increased, players are faster, they're hitting the ball harder.

"We owe it to our players to protect them and give them a more sustainable sport."

So what actions are being taken and what further steps could be implemented?

Condensing the Tour Schedule

The 2025 season spanned 47 weeks for many players on the ATP circuit, commencing with the United Cup team event in late December 2024 and concluding with the Davis Cup final in late November.

The women's circuit ended two weeks earlier when the WTA Finals concluded in early November. The governing body 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 "lightly," while the WTA Tour says 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 "anti-competitive practices and a blatant disregard for player welfare."

Overhauling the calendar is an obvious solution but cannot be implemented readily given the intricate web of tennis governance, where the four Grand Slams, ATP, WTA, and ITF each have significant influence.

"We must consider whether we can create more time at the end of the year for an longer break, 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 consistent campaigner for adjustments, says the season should not go past 1 November.

The ATP Tour has cut the number of events which factor into the rankings for 2026, which it believes will reduce "the total burden" on the players.

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

"This level of choice is unusual in pro sports. But with that comes obligation - knowing when to push and when to recover."

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

"I believe competitors are more worn out mentally and physically because they're being on the road longer," stated Britain's former men's world number one, Andy Murray.

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

Players are more prone to 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 switches in court surfaces.

Fewer Late Nights & More Ball Consistency

When a memorable contest at the Australian Open ended in the early hours in 2023, it promised to spark change.

In 2024, the tours introduced a new rule preventing matches starting after 11pm.

But there have continued to be instances of matches ending deep into the night - which medical experts insist.

"After a match concludes, an athlete's day isn't over," explained Dr. Sikka.

"Media interviews, rehabilitation, and treatment are required. Your day doesn't finish until much later.

"Your body, brain and nerves don't have chance to recover. No other major sport imposes such conditions."

A lack of standardization in tournament equipment - leading to changes in feel and performance - has been identified as a source of a rise in upper body injuries.

"I have suffered numerous arm, shoulder, and wrist issues," stated one top British player, "and I'm seeing more and more of these injuries across the tours."

A former US Open champion, who retired last year with an persistent wrist issue, believes tournaments in the same swing should use one type of ball.

"Implementing this would not be overly complex - 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 project "complete uniformity" in the coming years.

Take Lessons from the NFL & Shield Developing Athletes

Sports scientists believe tennis must take cues from how American team sports use data to direct the welfare of its stars.

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

"The NFL has made many rule changes based on empirical evidence," said an analytics expert whose firm provides data to monitor player welfare.

"We've seen the economic model is skyrocketing 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 benchmark."

Other leagues have implemented policies aimed at protecting specific positions, limiting their exertion at the professional level and putting limits for young players.

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.

"Training begins in childhood and have so many countless swings 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 increasing number of players are speaking out 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 bigger piece of the financial pie, as well as meaningful consultation about the tour schedule duration, elongated tournaments and scheduling.

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

Sympathy can be in short supply, though, given top players also participate in lucrative non-tour contests.

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