After Daria Kasatkina concluded her 2025 season ahead of schedule in October, the former world number eight explained how she had "encountered a barrier."

"The schedule is too much. Mentally and emotionally I'm at breaking point, and, unfortunately, I'm not alone," she stated.

The Ukrainian athlete Elina Svitolina, a former Wimbledon final four contender, had earlier declared she was not in "the right headspace" to carry on, while sitting Grand Slam champions Iga Swiatek and Carlos Alcaraz also believe the calendar is excessively lengthy.

The topic remains under discussion as the world's top tennis players gather again in Australia for the commencement of the 2026 season.

A marginally increased off-season than 2025 has been greeted positively. Nevertheless, a handful of weeks is not regarded as adequate time for adequate rest before training starts for an 11-month campaign regarded as among the most demanding in professional sport.

"The physical requirements of tennis are more intense than in the past," 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.

"It is our obligation to shield the competitors and give them a more sustainable sport."

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

Shortening the Season

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

The women's 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 address scheduling concerns.

The men's tour states it does not take the concerns of the players "casually," while WTA leadership notes player welfare will "consistently be the foremost concern."

That did not appease the PTPA, which began legal action against the men's and women's tours in March, pointing to "restrictive policies and an obvious indifference to player health."

Overhauling the calendar is an obvious solution but cannot be implemented readily 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 buy back time at the end of the year for an more substantial rest period, or can we create space during the season so there is a short hiatus," added 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 decreased the number of events which count towards the rankings for 2026, which it believes will lessen "the total burden" on the players.

"A factor frequently ignored: players select their own tournament plans," commented ATP chairman Andrea Gaudenzi.

"This level of choice is unusual in pro sports. But with that comes obligation - recognizing the right time to play and the right time to heal."

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

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

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

Players suffer more severe upper-body injuries in specific periods, according to player association statistics.

The organization says these "predictable clusters" are down to the tour schedule layout and the switches in court surfaces.

Reducing Late Finishes & Standardizing Equipment

When a notable match at the Australian Open ended in the middle of the night in 2023, it promised to spark change.

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

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

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

"Media interviews, rehabilitation, and treatment are required. Your day doesn't end at midnight.

"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 bounce and speed - has been pointed to 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 such ailments are increasingly prevalent among peers."

A former US Open champion, who stepped away last year with an persistent wrist issue, believes tournaments in the same seasonal segment should use one uniform 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 moved towards a more unified ball-approval process during 2025 and anticipate "full alignment" in the coming years.

Emulate American Sports & Safeguard Juniors

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

Following data-led analysis, the NFL mandated consistent playing surfaces and enhanced 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.

"We've seen the economic model is skyrocketing because their games are so competitive and they're maintaining a healthy roster.

"They're putting their money where their mouth is by protecting athletes and devoting significant resources – that model is the benchmark."

Other leagues have enacted regulations aimed at protecting throwers, limiting their throws at the professional level and putting guidelines for juniors.

Some retired players believe the strain put on the upper body of tennis players from a very early stage is a key element in their injuries later on.

"We start playing from such an early age and have so many repetitions 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 increasing number of players are becoming vocal about the demands placed on them.

Current world number ones are among a collection of elite athletes increasing demands on the Grand Slams with calls for a larger share of revenue, as well as meaningful consultation about the calendar extent, elongated tournaments 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 next campaign.

Sympathy can be in short supply, though, given top players occasionally sign up for lucrative showcase matches.

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