"They can’t sit isolated and eat organic bananas all day”: Holger Rune’s mother calls for changes in anti-doping policies after Sinner’s doping case.
ATP
Holger Rune's mother, Aneke Rune, recently commented on Jannik Sinner's case and the growing concerns players now have about the potential risks of contamination. The Danish woman called for changes in the ITIA and WADA for cases involving minimal contamination, like that of the Italian player.
Recall that World No. 1 Sinner suffered Clostebol contamination indirectly after his physiotherapist applied a spray to treat his own hand injuries. When treating Sinner without gloves, a minuscule trace of the banned substance, less than a millionth of a gram, was transferred to the Italian.

Sinner recently accepted a three-month suspension in agreement with the World Anti-Doping Agency (WADA), avoiding a court trial that could have led to a suspension of one to two years if found guilty by an independent tribunal.
The case has dominated the tennis world for months, with many criticizing the process – including Nick Kyrgios – for allegedly giving Sinner preferential treatment. As Sinner’s nightmare draws to an end while he serves his suspension, the procedures are still under scrutiny, with questions about their transparency and fairness.
In a recent interview with the Danish website Ekstra Bladet, Holger Rune’s mother and agent, Aneke, shared her opinion on the Sinner case: “If you read a little about clostebol, you can see how frighteningly easy it can be transferred to other people if it has been used by a third party,” she said. “That, I think, is almost the scariest thing about this case. Think about how many fans you give high fives to, surfaces you touch, etc.”

“Otherwise the players will become neurotic. Now clostebol is a prescription drug in most countries, and there is therefore little risk of transmission. But not in Italy. It should be as a consequence of all the cases they have had, to protect their athletes,” she added. “But there may be other substances that are also easily transmitted, and therefore it is important to look at the lower limit values, so that the athletes do not end up isolating themselves completely.”
According to Aneke Rune, certain cases need to be reviewed by the ITIA for the future: “I read about an athlete recently where they had found traces of something that occurs in strong alcohol, but which in isolation can be performance-enhancing. There are also steaks where the cow has eaten steroids, which show up in tests - this is also a problem that several athletes have run into.”

“They can't sit isolated from all the people and eat organic bananas all day for fear of a test showing 0.00000000001 trace of something.”
“I personally think that three months and a year of processing time is too long. I don't know the details of the individual case enough to say whether it is reasonable. That is WADA's (World Anti-Doping Agency, ed.) board.”
“As I read it, I think most of the athletes' criticism is that there are such different guidelines in individual cases where there are obvious accidents and not intentional doping.”

“But I also think that this is one of the areas, like the limit values, that WADA and ITIA must look at after the recent cases; that for example, it must not take more than a maximum of x number of days to confirm whether there is poisoning or not, so that the athletes can quickly resume their careers and not sit out for a year because some office people mess around with some analyses with 0.000000001 mg.”
Point. Of. The. Tournament.

- One step by another step -- WTA continues to 'lose the plot'. Too many hi-tech microphones being installed at most venues!!! Remove them (especially those along the hallways, sidewalks, and pathways throughout the venues. Not to mention (most of all) remove the mic's from the Players/Coaches Box.
mandoist06-11-2026 - Enough of her bullshit. Go marry someone.
mandoist06-11-2026 - Don't you just love this young lady!? We fans often expect athletes to be supermen and superwomen, often forgetting that they WILL GET TIRED! I love Alex's perspective. Tiredness for an athlete should never be viewed as a negative, especially if you are healthy, taking care of your body and mental health and putting in the work. What a mature perspective. Good for you, Alex!Rapunzel05-11-2026
- Jess is absolutely correct! But the disrespect is a trait I have noticed in most of the Russian players. Mirra is good but very immature and lacks humility. Conceivable needs to get a handle on that!Rapunzel05-11-2026
- Having spent weeks and weeks through the years on tour, I can say with confidence that Conchita was (is) one of the very few who realize the surprising level of maturity (and sometimes lack of) which Mirra seems to have developed in such a demanding adult world of Pro-Tennis. While at the same time reminding herself (Conchita, that is) that Mirra is still young and developing mentally and physically. The general public may forget at times, or not at all realize, these modern era young athletes do not have a 'normal' Youth. It's a major sacrifice, among countless sacrifices, these athletes must make. People who blow-off that fact are ignorant and unfair when they blurt out, "They choose fame so they have to put up with the intrusions on their lives". No, they do not.
mandoist05-11-2026 - Okay... someone with a camera was EAVESDROPPING on a private conversation. Shouldn't that be the point of discussion here? Regardless of the sensationalist crap by media, Pegula (and anyone) has a right to an opinion. There used to be an expectation that private conversations were respected, regardless of 'stardom' and whatever other defensive excuses media tries to shove in our faces. Boo-hoo if feelings are hurt. BTW: Having been employed at various tourney venues, etc., I can't tell you how nasty and offensive players can be when discussing their opponents and colleagues... in "private". Well, I could, but won't. I also challenge anyone to deny what Jessica said is false.
mandoist05-11-2026 - Vacherot is Mongasque, rather than Swiss. The tournament was Swiss :DTrwd7702-11-2026
- After a couple decades traveling to IIHF tourneys overseas... our family is done with it... and I will not be the only one!! Bad enough the NHL allows Ovachenko (a Putin Supporter and Campaigner) to live and play in the USA. Let's not forget the STATE SPONSORED RUSSIAN DOPING PROGRAMS still in effect today.
mandoist31-10-2026 - Osaka's mental state apparently does not allow her to reach any more Quarter Finals? I mean, she doesn't really have the time for tennis with all the pre-planning that must go into her 12 year-old "fashion" goals.
mandoist29-10-2026 - With her money one would think she could afford a better team of Psychiatrists?
