At the point when Daria Kasatkina cut short her 2025 season ahead of schedule in October, the ex-top ten player described how she had "hit a wall."

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

The Ukrainian athlete Elina Svitolina, a former Wimbledon final four contender, had earlier announced she was not in "the psychological condition" to persist, while sitting Grand Slam champions Iga Swiatek and Carlos Alcaraz furthermore are convinced the calendar is overly extended.

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

A slightly longer off-season than 2025 has been greeted positively. Nevertheless, several weeks is not considered sufficient time for thorough recuperation before training starts for an 11-month campaign regarded as among the most onerous 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 owe it to our players to protect them and give them a more manageable sport."

So what is being done and what additional measures could be implemented?

Shortening the Season

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

The women's circuit finished two weeks earlier when the tour finals concluded in early November. The governing body 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 "lightly," while the WTA Tour says player welfare will "always remain a top priority."

That did not placate the PTPA, which began legal action against the men's and women's tours in March, pointing to "unfair practices and a clear neglect of athlete well-being."

Overhauling the calendar is an clear answer but cannot be achieved easily given the complex nature of tennis governance, where the four Grand Slams, ATP, WTA, and ITF each have significant influence.

"We need to think about 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," 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 decreased the number of events which factor into the rankings for 2026, which it thinks will reduce "overall demands" on the players.

"One point that often gets overlooked: players choose their own schedules," stated ATP chairman Andrea Gaudenzi.

"That freedom is rare in professional sport. But with that comes obligation - recognizing the right time to play and the right time to heal."

Stretching several required events 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 spending more days away," stated Britain's former men's world number one, Andy Murray.

In addition to mental burnout, there are apprehensions 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 "predictable clusters" are down to the structure of the calendar and the transitions between court surfaces.

Reducing Late Finishes & Standardizing Equipment

When a high-profile game at the Australian Open finished in the early hours in 2023, it promised to spark change.

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

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

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

"You have to do media, recover, work with the physiotherapist. Your day doesn't end at midnight.

"There is insufficient opportunity for the body and mind to heal. There is no other sport which mandates that."

The use of varying balls at different events - leading to changes in feel and performance - 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," said one top British player, "and I observe these types of injuries becoming more common."

A former US Open champion, who stepped away last year with an chronic wrist problem, believes tournaments in the same circuit should use one uniform ball.

"It shouldn't be too difficult - 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 project "complete uniformity" in the coming years.

Take Lessons from the NFL & Shield Developing Athletes

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

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

"Their financial commitment matches their rhetoric by protecting athletes and investing hugely – that model is the benchmark."

Other leagues have implemented policies aimed at protecting throwers, limiting their workload at the professional level and putting age restrictions.

Some retired players believe the strain put on the upper body of tennis players from a very early stage is a significant factor 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.

"Eventually, the wrist bears the brunt. 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 rising contingent of players are speaking out about the demands placed on them.

Current world number ones are among a collection of elite athletes applying force on the Grand Slams with calls for a bigger piece of the financial pie, as well as meaningful consultation about the tour schedule duration, extended events and fixture planning.

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

Support is not always forthcoming, though, given top players also participate in lucrative exhibition events.

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