At the point when Daria Kasatkina concluded her 2025 season early in October, the ex-top ten player described how she had "reached her limit."

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

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 additionally are convinced the calendar is overly extended.

This subject is still being argued as the world's leading tennis players assemble once more in Australia for the commencement of the 2026 season.

A marginally increased off-season than 2025 has been greeted positively. However, a few weeks is not regarded as enough time for thorough recuperation before work commences for an eleven-month schedule regarded as among the most grueling in professional sport.

"The demands of tennis are harder than ever before," commented Dr. Robby Sikka, chief medical officer at the Professional Tennis Players' Association (PTPA).

"The duration of play has increased, 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 additional measures could be taken?

Reducing the Calendar Length

The 2025 season covered 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 women's season ended two weeks earlier when the tour finals wrapped up in early November. The International Tennis Federation moved the Billie Jean King Cup Finals forward to September to address scheduling concerns.

The ATP Tour says it does not take the concerns of the players "lightly," while WTA leadership notes player welfare will "perpetually be the highest focus."

That did not placate the PTPA, which initiated a lawsuit 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 apparent fix but cannot be implemented readily given the complex nature of tennis governance, where the four Grand Slams, ATP, WTA, and ITF each have significant influence.

"It is crucial to evaluate whether we can create more time at the end of the year for an more substantial rest period, or can we allow for a pause during the season so there is a brief respite," 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 cut the number of events which are included in 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.

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

Stretching several required events across a fortnight - creating so-called 'extended events' - has also been criticized.

"I think players are more mentally tired and more fatigued because they're spending more days away," 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 suffer more severe upper-body injuries in particular times of the year, according to available data.

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

Reducing Late Finishes & Standardizing Equipment

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

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

But there have continued to be instances of matches finishing well past midnight - which medical experts argue must not be glorified.

"Once the final point is played, a player's duties continue," said 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. No other major sport imposes such conditions."

The use of varying balls at different events - 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 such ailments are increasingly prevalent among peers."

A former US Open champion, who ended his career last year with an chronic wrist problem, thinks tournaments in the same swing should use one uniform 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 moved towards a more centralized ball-selection system during 2025 and anticipate "total consistency" in the coming years.

Take Lessons from the NFL & Shield Developing Athletes

Sports scientists believe tennis must learn from how American team sports use data to guide the wellbeing of its stars.

Using data-led analysis, the NFL mandated 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.

"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 allocating major funds – that model is the benchmark."

Other leagues have introduced rules aimed at protecting specific positions, limiting their workload at the professional level and putting age restrictions.

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

"We start playing from such an early age and have so many iterations 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."

Athletes Are Pushing for Reform - What Are Their Demands?

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 increased portion of tournament income, as well as genuine dialogue about the length of the season, elongated tournaments and match timing.

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

Support is not always forthcoming, though, given top players sometimes commit to lucrative non-tour contests.

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