At the point when Daria Kasatkina cut short her 2025 season early in October, the one-time elite competitor described how she had "reached her limit."

"The itinerary is excessive. Psychologically and emotionally, I am drained, and, regrettably, I'm not alone," she expressed.

Elina Svitolina of Ukraine, a two-time Wimbledon semi-finalist, had already announced she was not in "the psychological condition" to carry on, while reigning Grand Slam champions Iga Swiatek and Carlos Alcaraz additionally believe the calendar is too long.

This subject continues to be debated as the world's foremost tennis players assemble once more in Australia for the beginning of the 2026 season.

A marginally increased off-season than 2025 has been greeted positively. However, a handful of weeks is not seen as adequate time for adequate recovery before work commences for an eleven-month schedule seen as among the most demanding in professional sport.

"Tennis places greater strain on athletes now than it ever has," commented Dr. Robby Sikka, medical director 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 viable sport."

So what measures are in place and what further steps could be enacted?

Condensing the Tour Schedule

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

The women's circuit ended two weeks earlier when the tour finals finished in early November. The governing body moved the Billie Jean King Cup Finals forward to September to address 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 "consistently be the foremost concern."

That did not placate 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."

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

"We need to think about whether we can reclaim time at the end of the year for an longer break, or can we buy time during the season so there is a brief respite," 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 reduced the number of events which factor into the rankings for 2026, which it believes will lessen "the cumulative strain" on the players.

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

"This level of choice is unusual in pro sports. But with that comes responsibility - understanding when to compete and when to rest."

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

"I believe competitors are more worn out mentally and physically because they're away from home for extended periods," stated Britain's former men's world number one, Andy Murray.

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

Players are more prone to upper-body injuries in specific periods, according to PTPA research.

The organization says these "anticipated spikes" are down to the structure of the calendar and the turnarounds between court surfaces.

Minimizing Midnight Matches & Uniform Balls

When a memorable contest at the Australian Open finished in the middle of the night in 2023, it seemed set to trigger adjustments.

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

But there have persisted instances of matches concluding long after midnight - which medical experts argue must not be glorified.

"After a match concludes, an athlete's day isn't over," 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. No other major sport imposes such conditions."

Different tournaments playing with different balls - leading to changes in weight and pace - has been identified as a source of increased upper body injuries.

"My career has been plagued by injuries to the arm and 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 stepped away last year with an persistent wrist issue, believes tournaments in the same swing should use one standard 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 unified ball-approval process during 2025 and anticipate "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 guide the health of its stars.

Using data-led analysis, the NFL required consistent playing surfaces and improved helmet technology to minimize 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 ensuring star athletes are available.

"They're putting their money where their mouth is by protecting athletes and investing hugely – that model is the exemplar."

Other leagues have enacted regulations aimed at protecting specific positions, limiting their throws 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.

"We pick up a racket as kids and have so many countless swings of our groundstrokes," said the former champion.

"Eventually, the wrist bears the brunt. Way more players have problems with the wrist. I think the problem is the many, many repetitions."

Athletes Are Pushing for Reform - What Are Their Demands?

An increasing number of players are finding their voice about the demands placed on them.

Current world number ones are among a group of stars applying force on the Grand Slams with calls for a bigger piece of the financial pie, as well as substantive discussions about the calendar extent, extended events and scheduling.

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 sometimes commit to 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.
