At the point when Daria Kasatkina concluded 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, regrettably, I'm not alone," she stated.

Elina Svitolina of Ukraine, a two-time Wimbledon semi-finalist, had previously declared she was not in "the psychological condition" to continue, while current Grand Slam champions Iga Swiatek and Carlos Alcaraz also believe the calendar is overly extended.

This issue remains under discussion as the world's top tennis players assemble once more in Australia for the commencement of the 2026 season.

A marginally increased off-season than 2025 has been received well. Nevertheless, several weeks is not regarded as sufficient time for thorough rest before training starts for an season lasting nearly a year considered among the most grueling in professional sport.

"The physical requirements of tennis are more intense than in the past," commented Dr. Robby Sikka, chief medical officer at the Professional Tennis Players' Association (PTPA).

"The duration of play has increased, 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 measures are in place and what additional measures could be enacted?

Condensing the Tour Schedule

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

The women's circuit ended two weeks earlier when the season-ending championships finished in early November. The International Tennis Federation moved the Billie Jean King Cup Finals forward to September to alleviate 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 "always remain a top priority."

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

Revamping the calendar is an apparent fix 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.

"We must consider whether we can buy back time at the end of the year for an more substantial rest period, or can we create space during the season so there is a short hiatus," noted Dr. Sikka.

Former world number one Andy Roddick, a consistent campaigner for adjustments, says the season should not go past 1 November.

The ATP Tour has decreased the number of events which are included in the rankings for 2026, which it is confident will lessen "the total burden" on the players.

"An aspect commonly missed: players choose their own schedules," stated ATP chairman Andrea Gaudenzi.

"Such autonomy is uncommon in elite athletics. But with that comes responsibility - knowing when to push and when to recover."

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

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

Alongside mental burnout, there are concerns about the rising physical demands.

Players experience a higher rate of upper-body injuries in particular times of the year, according to PTPA research.

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

Reducing Late Finishes & Standardizing Equipment

When a high-profile game at the Australian Open concluded in the early hours in 2023, it seemed set to trigger adjustments.

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

But there have persisted instances of matches finishing well past midnight - which medical experts cannot be allowed to be "romanticised".

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

"Media interviews, rehabilitation, and treatment are required. Your day doesn't end at midnight.

"There is insufficient opportunity for the body and mind to heal. No other major sport imposes such conditions."

Different tournaments playing with different balls - leading to changes in feel and performance - has been cited as a source of more frequent 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, thinks tournaments in the same circuit should use one uniform 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 moved towards a more centralized ball-selection system during 2025 and expect "full alignment" in the coming years.

Learn from NFL & Protect Young Players

Sports scientists believe tennis must learn from how American team sports use data to guide the wellbeing of its stars.

Following data-led analysis, the NFL mandated consistent playing surfaces and enhanced helmet technology to minimize 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 maintaining a healthy roster.

"They're putting their money where their mouth is by protecting athletes and devoting significant resources – that model is the gold standard."

Other leagues have enacted regulations aimed at protecting throwers, limiting their throws at the professional level and putting limits for young players.

Some retired players believe the load 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.

"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."

Competitors Seek Adjustments - What Are the Key Issues?

An increasing number 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 genuine dialogue about the tour schedule duration, longer competitions 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 also participate in lucrative exhibition events.

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.
