Wales women tap into powers of menstruation

Natalia John, the Wales and Brython Thunder lock, has been playing rugby for over a decade. For most of that time she couldn’t explain why her performance levels would fluctuate so dramatically over the course of a month.

One week she was hammering out personal bests in the gym and backing that up with energetic displays on the pitch. A week or two later, she was nowhere near her best.

“I’d feel lethargic for no apparent reason,” she says.

“I’d get in my head and tell myself that I was weak and criticise myself. It wasn’t until our [Wales] physio, Jo Perkins, gave us a briefing on our menstrual cycles that I began to realise that these changes were totally normal.”

Now, in collaboration with the founding principal partner of Wales Women’s and Girl’s Rugby, Vodafone, Wales’ women are trialling a new concussion tracking technology to help female athletes better understand how the different phases of their menstrual cycle impact their performance, wellbeing and recovery.

Collecting data through an app on their phones, players are also able to monitor their symptoms of concussion from day to day.

Research from the University of Birmingham suggests that female athletes may suffer from both higher rates of concussion, as well as more severe and prolonged symptoms, compared to their male counterparts. Though the research is still being developed, there are suggestions that hormone variations could be a key factor.

“We’ve been able to see differences across the different phases of their menstrual cycle and the symptoms that they might be having,” Perkins explains.

“It’s a massive step in our research. We can see that in certain phases certain women may have either prolonged or heightened symptoms. Tracking concussions is something we’ve done for a while, but this helps us do so on an app in a user friendly way.

“There is some evidence to suggest that when players are in the luteal phase – right after ovulation – when progesterone [which prepares the lining in the uterus which helps a fertilised egg impact and grow] is higher, there is some evidence to suggest that women have more severe symptoms if they sustain a concussion.

“They think that’s because when suddenly the progesterone drops. That can have a potentially inflammatory effect which could result in longer symptoms.”

This information is a potential game changer for female players who, until recently, have been largely left in the dark regarding changes in their energy levels.

“It’s really empowering,” says John. “Before I’d attribute it to me feeling crap for no reason and then I’d in my head because I didn’t know what was going on. Now I accept that sometimes I won’t feel at my best and that allows me to give myself a break. Which then allows me to make more gains when I’m feeling on it.

“I’m now judging my on-field performances a little differently. Obviously I want to perform at my best every time, but there will be weeks where my body won’t be as strong or as on it.”

Both John and Perkins are optimistic that this new technology, along with more open conversations around female health, will advance the women’s game. There are numerous examples of sport leading the rest of society when it comes to social and cultural change and tethering high performance to something unique to women could break down existing stigmas.

“Historically various aspects of female health haven’t been discussed for reasons such as embarrassment, or it’s something that hasn’t been associated with performance,” Perkins adds.

“But now it’s clear that pelvic health, breast health, incontinence and severe menstrual cycle symptoms are all directly linked with high performance.

“The culture should be one where it is open and we talk about this. Not that we consider them normal, because we hopefully don’t have any women with severe symptoms of any sort. But if they do occur, we treat them appropriately without any shame or embarrassment.

“It’s a dream,” Perkins continues. “The evidence is showing us that we can actually add to the players’ loads in the luteal phase is very interesting. We can use our cycles to our advantage and that is very exciting for female sport. That is the same for the rest of the science where we individualise the programmes to suit the athlete and get the most out of their unique cycle. ”

The gap between the men’s and women’s game is closing every season in terms of support and the on-field product on show. But this is one variable that the likes of Antoine Dupont, Siya Kolisi and every other leading man will never have to contend with.

Soon enough, menstrual cycles will be regarded as advantages, rather than hindrances, for women at the elite level.

“Who knows where I’d be in my career if I had this technology when I started and I never gave myself such a hard time?” John wonders. “But I’m all about moving forward and I see it as a great opportunity that we have now to create something special for players down the road.

“In 10 years’ time we’ll have better concussion protocols, the players will be better protected and they’ll have more information about the relationship between the periods and their performance. I know some people might be apprehensive because it’s all so new, but we see it as a great responsibility to be taking this on.”

Why Les Kiss and Stuart Lancaster can lead Australia to glory

“Why are you so insistent on being wrong? Man United won in 2008 (beating Chelsea in the final). In 2009 Barcelona won, beating United.”

Good lad, just checking. So you’re not a bot! Chelsea bombed the 2008 final more than United won it. John Terry… couldn’t happen to a nicer fella.


“The gap between wins ignores the finals contested. 2 in 2 years with his City Triumph. The most recent put him in the elite company of managers to have won it with multiple clubs. Yet more late career success and history.”

Again - you’re not correct. City won the CL in 2023, and made the final in 2021. Those are the only two CL finals they have made.”

So the difference between 2021 and 2023 would of course be TWO YEARS. 24 months would account for 3 different seasons. They contested ECL finals twice in two years. The first in 2021 - which they lost - was still the first elite European final in the clubs then 141 year history. Explain clearly how that’s not an achievement? Guess what age he was then…


“I think your take on Gatland is pretty silly. Gatland was without Edwards in the 2013 and 2017 Lions tours and managed to do alright.”

I thought you don’t care what certain managers did 10 years ago…

Why would I address Eddie Jones? Why would he be deserving of a single sentence?


“I am aware Les Kiss has achieved great things in his career, but I don’t care what he did over ten years ago. Rugby was a different sport back then.”

So you haven’t watched even a minute of Super Rugby this year?


“lol u really need to chill out”

Simply frightful! If you’re not a bot you’re at least Gen-Z?

Why Les Kiss and Stuart Lancaster can lead Australia to glory

“Pep didn’t win the ECL in 2009. It was 2008 with Barca”

Why are you so insistent on being wrong? Man United won in 2008 (beating Chelsea in the final). In 2009 Barcelona won, beating United.


“The gap between wins ignores the finals contested. 2 in 2 years with his City Triumph. The most recent put him in the elite company of managers to have won it with multiple clubs. Yet more late career success and history.”

Again - you’re not correct. City won the CL in 2023, and made the final in 2021. Those are the only two CL finals they have made. With Barcelona, Pep made the semi final four consecutive times - with City he’s managed only 3 in 8 years. This year they didn’t even make the round of 16.


To re-cap, you wrote that Pep “has gotten better with age. By every measure.” There are some measures that support what you’re saying, but the vast majority of the measures that you have highlighted actually show the opposite.


I am aware Les Kiss has achieved great things in his career, but I don’t care what he did over ten years ago. Rugby was a different sport back then.


I think your take on Gatland is pretty silly. Gatland was without Edwards in the 2013 and 2017 Lions tours and managed to do alright. You’ve also not addressed Eddie Jones.


I agree wrt Schmidt. He would ideally be retained, but it wouldn’t work to have a remote head coach. He should definitely be hired as a consultant/analyst/selector though.


“Look at the talent that would be discarded in Schmidt and Kiss if your age Nazism was applied.”

lol u really need to chill out lad. Kiss and Schmidt would both be great members of the coaching set up in 2025, but it would be ridiculous to bank on either to retain the head coach role until 2031.

Why Les Kiss and Stuart Lancaster can lead Australia to glory

Pep didn’t win the ECL in 2009. It was 2008 with Barca. The gap between wins ignores the finals contested. 2 in 2 years with his City Triumph. The most recent put him in the elite company of managers to have won it with multiple clubs. Yet more late career success and history.


His time with City - a lower win ratio compared to Bayern Munich as you say - includes a 100 PT season. A feat that will likely never be surpassed. I appreciate you don’t follow soccer too closely but even casual fans refer to the sport in ‘pre and post Pep’ terms and all because of what he has achieved and is continuing to achieve, late career. There is a reason that even U10’s play out from the back now at every level of the game. That’s also a fairly recent development.


How refreshing to return to rugby on a rugby forum.


Ireland won a long over due slam in 2009. The last embers of a golden generation was kicked on by a handful of young new players and a new senior coach. Kiss was brought in as defence coach and was the reason they won it. They’d the best defence in the game at the time. He all but invented the choke tackle. Fittingly they backed it up in the next world cup in their 2011 pool match against… Australia. The instantly iconic image of Will Genia getting rag-dolled by Stephen Ferris.


His career since has even included director of rugby positions. He would have an extremely good idea of where the game is at and where it is going in addition to governance experience and dealings. Not least in Oz were many of the players will have come via or across Rugby League pathways.


Gatland isn’t a valid coach to compare too. He only ever over-achieved and was barely schools level without Shaun Edwards at club or test level. His return to Wales simply exposed his limitations and a chaotic union. It wasn’t age.


Schmidt is open to staying involved in a remote capacity which I think deserves more attention. It would be a brain drain to lose him. He stepped in to coach the ABs in the first 2022 test against Ireland when Foster was laid out with Covid. They mullered Ireland 42-19. He was still heavily involved in the RWC 2023 quarter final. Same story.


Look at the talent that would be discarded in Schmidt and Kiss if your age Nazism was applied.

Why Les Kiss and Stuart Lancaster can lead Australia to glory

“He won a ECL and a domestic treble at the beginning of his career.”

He won 2 ECLs at the beginning of his career (2009, 2011). Since then he’s won 1 in 15 years.


“He then won 3 leagues on the bounce later in his career”

He won 3 leagues on the bounce at the start of his career too - (2009, 2010, 2011).


If we’re judging him by champions league wins, he peaked in his late 30s, early 40s. If we’re judging him by domestic titles he’s stayed pretty consistent over his career. If we’re judging him by overall win rate he peaked at Bayern, and was better at Barcelona than at City. So no, he hasn’t gotten better by every measure.


“You mentioned coaches were older around the mid-2010’s compared to the mid-2000’s. Robson was well above the average age you’ve given for those periods even in the 90’s when in his pomp.”

Robson was 63-64 when he was at Barcelona, so he wasn’t very old. But yeah, he was slightly above the average age of 60 I gave for the top 4 premier league coaches in 2015, and quite a bit above the averages for 2005 and 2025.


“Also, comparing coaches - and their experiences, achievements - at different ages is unstable. It’s not a valid way to compare and tends to torpedo your own logic when you do compare them on equal terms. I can see why you don’t like doing it.”

Well my logic certainly hasn’t been torpedoed. Currently the most successful premier league coaches right now are younger than they were ten years ago. You can throw all the nuance at it that you want, but that fact won’t change. It’s not even clear what comparing managers “on equal terms” would even mean, or why it would be relevant to anything I’ve said.


“You still haven’t answered why Kiss could be a risker appointment?”

Because I’ve been talking to you about football managers. If you want to change the subject then great - I care a lot more about rugby than I do football.

But wrt Kiss, I don’t agree that 25 years experience is actually that useful, given what a different sport rugby was 25 years ago. Obviously in theory more experience can never be a bad thing, but I think 10 years of coaching experience is actually more than enough these days. Erasmus had been a coach for 13 years when he got the SA top job. Andy Farrell had been a coach for 9 when he got the Ireland job. I don’t think anyone would say that either of them were lacking in experience.


Now - what about coaches who do have 25+ years experience? The clearest example of that would be Eddie Jones, who started coaching 31 years ago. He did pretty well everywhere he worked until around 2021 (when he was 61), when results with England hit a sharp decline. He similarly oversaw a terrible run with Australia, and currently isn’t doing a great job with Japan.

Another example is Warren Gatland, who also started coaching full-time 31 years ago, after 5 years as a player-coach. Gatland did pretty well everywhere he went until 2020 (when he was 56), when he did a relatively poor job with the Chiefs, before doing a pretty poor job with the Lions, and then overseeing a genuine disaster with Wales. There are very few other examples, as most coaches retire or step back into lesser roles when they enter their 60s. Mick Byrne actually has 34 years experience in coaching (but only 23 years coaching in rugby) and at 66 he’s the oldest coach of a top 10 side, and he’s actually doing really well. He goes to show that you can continue to be a good coach well into your 60s, but he seems like an outlier.


So the point is - right now, Les Kiss looks like a pretty reliable option, but 5 years ago so did Eddie Jones and Warren Gatland before they went on to prove that coaches often decline as they get older. If Australia want Kiss as a short term appointment to take over after Schmidt leaves in the summer, I don’t think that would be a terrible idea - but NB wanted Kiss as a long term appointment starting in 2027! That’s a massive risk, given the chance that his aptitude will begin to decline.


Its kind of analagous to how players decline. We know (for example) that a fly-half can still be world class at 38, but we also know that most fly-halves peak in their mid-to-late 20s, so it is generally considered a risk to build your game plan around someone much older than that.
