At the point when Daria Kasatkina cut short her 2025 season early in October, the one-time elite competitor explained how she had "hit a wall."

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

Ukraine's Elina Svitolina, a former Wimbledon final four contender, had earlier declared she was not in "the right headspace" to persist, while current Grand Slam champions Iga Swiatek and Carlos Alcaraz also believe the calendar is overly extended.

This issue continues to be debated as the world's leading tennis players gather again in Australia for the commencement of the 2026 season.

A slightly longer off-season than 2025 has been greeted positively. However, a few weeks is not regarded as adequate time for thorough rest before training starts for an season lasting nearly a year seen as among the most grueling in professional sport.

"The physical requirements of tennis are more intense than in the past," commented Dr. Robby Sikka, medical director 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 viable sport."

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

Condensing the Tour Schedule

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

The women's season 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 "lightly," while the women's tour asserts player welfare will "consistently be the foremost concern."

That did not placate the PTPA, which began legal action against the men's and women's tours in March, pointing to "unfair practices and a clear neglect of athlete well-being."

Revamping the calendar is an clear answer but cannot be achieved easily given the complex nature of tennis governance, where the four Grand Slams, ATP, WTA, and ITF each have major stakes.

"We must consider whether we can reclaim 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," 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 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 determine their own playing calendar," stated ATP chairman Andrea Gaudenzi.

"That freedom is rare in professional sport. But with that comes responsibility - understanding when to compete and when to rest."

Extending several mandatory tournaments 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 spending more days away," stated Britain's former men's world number one, Andy Murray.

Alongside mental burnout, there are worries about the increased physical demands.

Players experience a higher rate of upper-body injuries in specific periods, according to available data.

The organization says these "predictable clusters" are down to the structure of the calendar and the turnarounds between court surfaces.

Reducing Late Finishes & Standardizing Equipment

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

In 2024, the tours brought in a new rule preventing matches commencing later than 11pm.

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

"When you are done playing you just don't go home," said Dr. Sikka.

"There are press obligations, recovery sessions, and physio appointments. Your day doesn't end at midnight.

"Your body, brain and nerves don't have chance to recover. There is no other sport which mandates that."

A lack of standardization in tournament equipment - leading to changes in weight and pace - has been identified as a source of increased upper body injuries.

"My career has been plagued by injuries to the arm and wrist," said one top British player, "and I observe these types of injuries becoming more common."

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

"It shouldn't be too difficult - 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 began using a more unified ball-approval process 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 direct the wellbeing of its stars.

Following data-led analysis, the NFL required 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 keeping players out on the field.

"Their financial commitment matches their rhetoric by protecting athletes and devoting significant resources – that model is the exemplar."

Other leagues have implemented policies aimed at protecting throwers, limiting their workload at the professional level and putting limits for young players.

Some retired players believe the stress put on the upper body of tennis players from a tender age is a key element in their injuries later on.

"We pick up a racket as kids 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."

Athletes Are Pushing for Reform - What Are Their Demands?

An growing group 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 larger share of revenue, as well as meaningful consultation about the length of the season, longer competitions and fixture planning.

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 also participate in lucrative showcase matches.

One Grand Slam champion from Britain says the daily routine is a "test" but thinks top players "criticizing the calendar" is not a good look.
