At the point when Daria Kasatkina cut short her 2025 season early in October, the one-time elite competitor explained 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 expressed.

Elina Svitolina of Ukraine, a former Wimbledon final four contender, had already declared she was not in "the psychological condition" to continue, while reigning Grand Slam champions Iga Swiatek and Carlos Alcaraz also are convinced the calendar is overly extended.

The topic 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 received well. However, a few weeks is not regarded as sufficient time for thorough recovery before training starts for an eleven-month schedule seen as among the most onerous in professional sport.

"The physical requirements of tennis are more intense than in the past," said 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 owe it to our players to protect them and give them a more sustainable sport."

So what is being done and what next actions could be implemented?

Reducing the Calendar Length

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

The women's circuit concluded 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 alleviate scheduling concerns.

ATP officials claim it does not take the concerns of the players "casually," while the WTA Tour says player welfare will "consistently be the foremost concern."

That failed to satisfy the PTPA, which began legal action against the men's and women's tours in March, citing "unfair practices and a clear neglect of athlete well-being."

Overhauling the calendar is an apparent fix but cannot be implemented readily given the intricate web of tennis governance, where the four Grand Slams, ATP, WTA, and ITF each have major stakes.

"We need to think about whether we can buy back 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," added Dr. Sikka.

Former world number one Andy Roddick, a vocal proponent of reform, 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 thinks will lessen "the cumulative strain" on the players.

"An aspect commonly missed: players select their own tournament plans," stated ATP chairman Andrea Gaudenzi.

"Such autonomy is uncommon in elite athletics. But with that comes responsibility - understanding when to compete and when to rest."

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

"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 increased physical demands.

Players are more prone to upper-body injuries in particular times of the year, according to available data.

The organization says these "foreseeable patterns" are down to the structure of the calendar and the transitions between court surfaces.

Minimizing Midnight Matches & Uniform Balls

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 preventing matches commencing later than 11pm.

But there have continued to be instances of matches concluding long after midnight - which medical experts cannot be allowed to be "romanticised".

"Once the final point is played, a player's duties continue," said 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. This is a unique demand in the sporting world."

Different tournaments playing with different balls - leading to changes in bounce and speed - has been cited as a source of more frequent upper body injuries.

"My career has been plagued by injuries to the arm and wrist," said 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 ongoing wrist injury, thinks tournaments in the same circuit should use one standard 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 adopted a more centralized ball-selection system during 2025 and expect "complete uniformity" in the coming years.

Learn from NFL & Protect Young Players

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

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

"The league has altered its regulations using concrete research," 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 devoting significant resources – that model is the benchmark."

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

Some retired players believe the strain put on the upper body of tennis players from a young age is a major contributor 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."

Players 'Motivated' for Change - What Do They Want?

An growing group of players are finding their voice 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 substantive discussions 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 new season.

Sympathy can be in short supply, though, given top players sometimes commit to lucrative showcase matches.

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