At the point when Daria Kasatkina cut short her 2025 season early in October, the former world number eight explained how she had "encountered a barrier."

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

Ukraine's Elina Svitolina, a double Wimbledon semi-final participant, had previously announced she was not in "the right headspace" to persist, while current Grand Slam champions Iga Swiatek and Carlos Alcaraz additionally believe the calendar is overly extended.

This issue continues to be debated as the world's foremost tennis players assemble once more in Australia for the beginning of the 2026 season.

A slightly longer off-season than 2025 has been welcomed. However, a few weeks is not regarded as adequate time for adequate recovery before training starts for an 11-month campaign 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).

"The duration of play has increased, 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 further steps could be enacted?

Reducing the Calendar Length

The 2025 season covered 47 weeks for many men on tour, beginning 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 WTA Finals finished in early November. The ITF 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 the women's tour asserts player welfare will "consistently be the foremost concern."

That did not placate the PTPA, which commenced proceedings against the men's and women's tours in March, referencing "anti-competitive practices and a blatant disregard for player welfare."

Revamping the calendar is an clear answer but cannot be achieved easily given the intricate web of tennis governance, where the four Grand Slams, ATP, WTA, and ITF each have controlling interests.

"It is crucial to evaluate whether we can reclaim time at the end of the year for an longer break, or can we allow for a pause during the season so there is a brief respite," said 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 factor into the rankings for 2026, which it believes will lessen "the total burden" on the players.

"A factor frequently ignored: players choose their own schedules," stated 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 faulted.

"In my view, athletes are more psychologically drained and exhausted because they're away from home for extended periods," said Britain's former men's world number one, Andy Murray.

Alongside mental burnout, there are apprehensions about the growing physical demands.

Players suffer more severe upper-body injuries in certain months, according to PTPA research.

The organization says these "anticipated spikes" are down to the structure of the calendar and the switches in court surfaces.

Reducing Late Finishes & Standardizing Equipment

When a memorable contest at the Australian Open finished in the wee hours in 2023, it was expected to drive reform.

In 2024, the tours implemented a new rule prohibiting matches beginning past 11pm.

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

"After a match concludes, an athlete's day isn't over," explained Dr. Sikka.

"You have to do media, recover, work with the physiotherapist. Your day extends well beyond the match.

"Your body, brain and nerves don't have chance to recover. 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 identified as a source of increased upper body injuries.

"I've had a lot of injuries in my arm, my shoulder, my wrist," said one top British player, "and such ailments are increasingly prevalent among peers."

A former US Open champion, who ended his career last year with an ongoing wrist injury, believes tournaments in the same circuit should use one type of ball.

"This should be a straightforward solution - 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 expect "complete uniformity" in the coming years.

Emulate American Sports & Safeguard Juniors

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 advanced 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.

"We've seen the economic model is skyrocketing 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 enacted regulations aimed at protecting specific positions, limiting their exertion 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 major contributor in their injuries later on.

"Training begins in childhood and have so many countless swings 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 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 increased portion of tournament income, as well as meaningful consultation about the tour schedule duration, extended events and scheduling.

Last year, a top-ten American player said it was "unreasonable" 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 grind is a "difficulty" but thinks top players "moaning about the calendar" is not a good look.
