When Daria Kasatkina ended her 2025 season early in October, the one-time elite competitor described how she had "hit a wall."

"The schedule is too much. My mental and emotional state is frayed, and, unfortunately, I'm not alone," she stated.

The Ukrainian athlete Elina Svitolina, a two-time Wimbledon semi-finalist, had earlier declared she was not in "the right headspace" to carry on, while reigning Grand Slam champions Iga Swiatek and Carlos Alcaraz additionally think the calendar is excessively lengthy.

This issue is still being argued as the world's foremost tennis players gather again in Australia for the beginning of the 2026 season.

A somewhat extended off-season than 2025 has been welcomed. Nevertheless, several weeks is not considered sufficient time for thorough rest before preparations begin for an season lasting nearly a year regarded as among the most demanding in professional sport.

"Tennis places greater strain on athletes now than it ever has," commented 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 sustainable sport."

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

Shortening the Season

The 2025 season spanned 47 weeks for many men on tour, 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 ITF 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 "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, referencing "unfair practices and a clear neglect of athlete well-being."

Overhauling 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 major stakes.

"We need to think about whether we can reclaim time at the end of the year for an longer break, or can we create space during the season so there is a brief respite," noted 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 decreased the number of events which factor into the rankings for 2026, which it thinks will diminish "the cumulative strain" on the players.

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

"That freedom is rare in professional sport. But with that comes obligation - knowing when to push and when to recover."

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

"I think players are more mentally tired and more fatigued 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 apprehensions about the increased physical demands.

Players are more prone to upper-body injuries in certain months, according to player association statistics.

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

Minimizing Midnight Matches & Uniform Balls

When a high-profile game at the Australian Open concluded in the middle of the night in 2023, it was expected to drive reform.

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

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

"When you are done playing you just don't go home," explained 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."

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

"I have suffered numerous arm, shoulder, and wrist issues," said one top British player, "and I'm seeing more and more of these injuries across the tours."

A former US Open champion, who retired last year with an chronic wrist problem, believes tournaments in the same swing should use one standard 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 really helpful to the players," he said.

The tours adopted a more centralized ball-selection system during 2025 and anticipate "total consistency" 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 inform the welfare of its stars.

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

"The financial returns have increased dramatically 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 investing hugely – that model is the gold standard."

Other leagues have introduced rules aimed at protecting throwers, limiting their exertion at the professional level and putting guidelines for juniors.

Some retired players believe the stress put on the upper body of tennis players from a very early stage is a significant factor in their injuries later on.

"We pick up a racket as kids and have so many iterations 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."

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

An growing group of players are becoming vocal 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, extended events and fixture planning.

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

Public understanding may be limited, though, given top players sometimes commit to lucrative showcase matches.

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