When Daria Kasatkina concluded her 2025 season early in October, the former world number eight described how she had "reached her limit."

"The calendar is overwhelming. Mentally and emotionally I'm at breaking point, 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 mental space" to continue, while current Grand Slam champions Iga Swiatek and Carlos Alcaraz additionally believe the calendar is excessively lengthy.

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

A slightly longer off-season than 2025 has been welcomed. However, a handful of weeks is not regarded as adequate time for thorough recovery before work commences for an 11-month campaign regarded as among the most demanding 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).

"Matches and rallies are longer, players are faster, they're hitting the ball harder.

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

So what actions are being taken and what next actions could be enacted?

Condensing the Tour Schedule

The 2025 season lasted 47 weeks for many men on tour, 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 WTA Finals wrapped up in early November. The International Tennis Federation 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 "without seriousness," while the women's tour asserts 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, citing "restrictive policies and an obvious indifference to player health."

Overhauling the calendar is an clear answer but cannot be accomplished simply given the intricate web of tennis governance, where the four Grand Slams, ATP, WTA, and ITF each have major stakes.

"It is crucial to evaluate whether we can buy back time at the end of the year for an longer break, or can we create space during the season so there is a mini-break," added 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 cut the number of events which are included in the rankings for 2026, which it thinks will reduce "overall demands" on the players.

"A factor frequently ignored: players determine their own playing calendar," remarked ATP chairman Andrea Gaudenzi.

"This level of choice is unusual in pro sports. But with that comes responsibility - recognizing the right time to play and the right time to heal."

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

"I believe competitors are more worn out mentally and physically because they're away from home for extended periods," opined Britain's former men's world number one, Andy Murray.

In addition to mental burnout, there are apprehensions about the growing physical demands.

Players experience a higher rate of upper-body injuries in specific periods, according to player association statistics.

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

Fewer Late Nights & More Ball Consistency

When a memorable contest at the Australian Open concluded in the early hours in 2023, it promised to spark change.

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

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

"Once the final point is played, a player's duties continue," added Dr. Sikka.

"You have to do media, recover, work with the physiotherapist. 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."

A lack of standardization in tournament equipment - leading to changes in feel and performance - has been pointed to as a source of increased upper body injuries.

"My career has been plagued by injuries to the arm and wrist," stated one top British player, "and such ailments are increasingly prevalent among peers."

A former US Open champion, who retired last year with an chronic wrist problem, believes tournaments in the same seasonal segment should use one uniform ball.

"It shouldn't be too difficult - 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 centralized ball-selection system during 2025 and anticipate "full alignment" in the coming years.

Emulate American Sports & Safeguard Juniors

Athletic performance experts believe tennis must take cues from how American team sports use data to direct the welfare of its stars.

Using data-led analysis, the NFL mandated consistent playing surfaces and enhanced helmet technology to reduce 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.

"Their commercial success has soared because their games are so competitive and they're ensuring star athletes are available.

"Their financial commitment matches their rhetoric by protecting athletes and allocating major funds – that model is the exemplar."

Other leagues have implemented policies aimed at protecting specific positions, 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.

"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 increasing number of players are finding their voice about the demands placed on them.

Current world number ones are among a collection of elite athletes increasing demands on the Grand Slams with calls for a increased portion of tournament income, as well as meaningful consultation about the calendar extent, longer competitions and match timing.

Last year, a top-ten American player said it was "absurd" 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 non-tour contests.

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