At the point when Daria Kasatkina ended her 2025 season ahead of schedule in October, the ex-top ten player detailed how she had "encountered a barrier."

"The itinerary is excessive. Mentally and emotionally I'm at breaking point, and, unfortunately, I'm not alone," she expressed.

The Ukrainian athlete Elina Svitolina, a two-time Wimbledon semi-finalist, had already declared she was not in "the mental space" to carry on, while sitting Grand Slam champions Iga Swiatek and Carlos Alcaraz also are convinced the calendar is excessively lengthy.

This subject is still being argued as the world's leading tennis players reconvene in Australia for the beginning of the 2026 season.

A slightly longer off-season than 2025 has been greeted positively. Nevertheless, several weeks is not considered enough time for adequate recuperation before work commences 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," said Dr. Robby Sikka, head of medicine at the Professional Tennis Players' Association (PTPA).

"Matches and rallies are longer, 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 actions are being taken and what next actions could be implemented?

Reducing the Calendar Length

The 2025 season spanned 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 circuit finished two weeks earlier when the WTA Finals finished 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 "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, citing "restrictive policies and an obvious indifference to player health."

Restructuring the calendar is an clear answer but cannot be accomplished simply 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 create more time at the end of the year for an longer break, or can we create space during the season so there is a short hiatus," added Dr. Sikka.

Former world number one Andy Roddick, a long-time advocate for change, says the season should not go past 1 November.

The ATP Tour has cut the number of events which factor into the rankings for 2026, which it thinks will reduce "overall demands" on the players.

"A factor frequently ignored: players determine their own playing calendar," remarked ATP chairman Andrea Gaudenzi.

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

Stretching several compulsory competitions across a fortnight - creating so-called 'super weeks' - has also been criticized.

"I believe competitors are more worn out mentally and physically because they're being on the road longer," opined Britain's former men's world number one, Andy Murray.

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

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

The organization says these "anticipated spikes" 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 finished in the early hours in 2023, it was expected to drive reform.

In 2024, the tours implemented a new rule stopping matches starting after 11pm.

But there have continued to be instances of matches finishing well past midnight - which medical experts insist.

"Once the final point is played, a player's duties continue," added Dr. Sikka.

"Media interviews, rehabilitation, and treatment are required. 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 cited as a source of increased upper body injuries.

"I have suffered numerous arm, shoulder, and wrist issues," 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 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 extremely beneficial to the players," he said.

The tours moved towards a more unified ball-approval process during 2025 and project "total consistency" in the coming years.

Take Lessons from the NFL & Shield Developing Athletes

Athletic performance experts believe tennis must emulate how American team sports use data to guide the welfare of its stars.

Using data-led analysis, the NFL mandated consistent playing surfaces and advanced helmet technology to lessen the risk of injury.

"The NFL has made many rule changes based on empirical evidence," 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 allocating major funds – that model is the gold standard."

Other leagues have introduced rules aimed at protecting pitchers, limiting their throws at the professional level and putting age restrictions.

Some retired players believe the stress put on the upper body of tennis players from a very early stage is a key element 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.

"Over time, the wrist suffers the consequences. 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 finding their voice about the demands placed on them.

Current world number ones are among a coalition of top players ramping up pressure on the Grand Slams with calls for a bigger piece of the financial pie, as well as meaningful consultation about the length of the season, elongated tournaments and scheduling.

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

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 daily routine is a "challenge" but thinks top players "moaning about the calendar" is not a good look.
