At the point when Daria Kasatkina cut short her 2025 season ahead of schedule in October, the former world number eight explained how she had "reached her limit."

"The calendar is overwhelming. Psychologically and emotionally, I am drained, and, sadly, I'm not alone," she expressed.

The Ukrainian athlete Elina Svitolina, a double Wimbledon semi-final participant, had already declared she was not in "the psychological condition" to carry on, while sitting Grand Slam champions Iga Swiatek and Carlos Alcaraz additionally believe the calendar is too long.

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

A marginally increased off-season than 2025 has been welcomed. However, a handful of weeks is not seen as enough time for adequate recovery before work commences for an eleven-month schedule considered among the most grueling 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.

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

So what measures are in place and what additional measures could be implemented?

Reducing the Calendar Length

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

The women's circuit concluded two weeks earlier when the tour finals concluded in early November. The International Tennis Federation moved the Billie Jean King Cup Finals forward to September to help combat scheduling concerns.

The ATP Tour says it does not take the concerns of the players "casually," while the women's tour asserts 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 "anti-competitive practices and a blatant disregard for player welfare."

Overhauling the calendar is an apparent fix but cannot be implemented readily given the complex nature of tennis governance, where the four Grand Slams, ATP, WTA, and ITF each have significant influence.

"It is crucial to evaluate whether we can create more time at the end of the year for an extended off season, or can we buy time during the season so there is a mini-break," 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 are included in the rankings for 2026, which it is confident will lessen "the cumulative strain" on the players.

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

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

Prolonging several required events across a fortnight - creating so-called 'extended events' - has also been questioned.

"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 rising physical demands.

Players suffer more severe upper-body injuries in particular times of the year, according to player association statistics.

The organization says these "predictable clusters" are down to the seasonal itinerary and the transitions between court surfaces.

Minimizing Midnight Matches & Uniform Balls

When a high-profile game at the Australian Open finished in the middle of the night in 2023, it seemed set to trigger adjustments.

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

But there have persisted instances of matches ending deep into the night - which medical experts argue must not be glorified.

"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 end at midnight.

"The physical and neurological systems lack adequate time to recuperate. This is a unique demand in the sporting world."

The use of varying balls at different events - leading to changes in feel and performance - has been identified as a source of increased upper body injuries.

"I have suffered numerous arm, shoulder, and wrist issues," commented 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, argues tournaments in the same circuit should use one standard 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 centralized ball-selection system during 2025 and expect "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 inform the health of its stars.

Following data-led analysis, the NFL required consistent playing surfaces and advanced helmet technology to lessen 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 keeping players out on the field.

"They're putting their money where their mouth is by protecting athletes and investing hugely – that model is the exemplar."

Other leagues have implemented policies aimed at protecting pitchers, limiting their workload 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 young age is a key element 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.

"Eventually, the wrist bears the brunt. 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 rising contingent 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 larger share of revenue, as well as genuine dialogue about the calendar extent, 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.

Public understanding may be limited, though, given top players occasionally sign up for lucrative exhibition events.

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