Everything You Need to Know About Period Tracking

“Track your period and train smarter.” That was the guarantee of FitrWoman, an application I downloaded on my cellular phone last tumble. I’d made the decision to try out it out due to the fact my physical fitness stage appeared to drop off precipitously last 12 months. Even nevertheless I was healthful and there were no main adjustments in my training, my stamina tanked. My joints and muscle tissue were unrelentingly restricted and brittle. My system did not look to recover—ever. I’d have a person or two good months followed by a lackluster a person wherever I could barely rally to run more than 3 miles and do some actual physical treatment exercise routines. The cycle recurring over and over. 

All 12 months, I tried every trick in the reserve to get back again on monitor, but blindly next the advice of the newest physical fitness content articles and sports activities research papers felt like a crapshoot (and not a very clever tactic). I was desperate for some concrete direction. When very little else appeared to help, I puzzled if I need to shell out more notice to my hormones and menstrual cycle. Truthfully, even nevertheless I’ve composed about the myriad techniques that women’s cycles can impact health and fitness and overall performance, I don’t routinely assume about it in the context of my very own lifestyle. I don’t compete at a high stage, and I wasn’t training for a purpose race. I like to run, swim, follow yoga, and enjoy exterior as significantly as probable, and I wasn’t sure my period genuinely mattered. But I’m in my early forties, and recently my period started performing finicky when it employed to run like clockwork. 

To the extent that I did assume about my period, I regarded it a liability when it came to sports—a nuisance at greatest, and a barrier to peak race-day success at worst. And I’m not alone. A 2016 research in the journal PLOS One identified that 55.4 percent of feminine athletes felt that their month-to-month cycle impacted their training or overall performance. However, menstruation is ordinarily a taboo and embarrassing subject to explore with friends, coaches, and teammates—so most ladies are remaining with couple approaches to mitigate the consequences of their cycle on their exercise routines apart from to grin and bear it. In fact, according to a 2019 investigation of responses from over fourteen,000 feminine Strava consumers, 72 percent reported they have acquired no training about physical exercise and their intervals.

Yet according to experts, understanding how ladies working experience the menstrual cycle is elementary to sports activities and overall performance. “Women’s physiology adjustments drastically across the complete cycle,” states Emma Ross, the former head of physiology for the English Institute of Activity, which supports British Olympic and Paralympic athletes. Hormones like estrogen and progesterone ebb and flow during the month, influencing almost everything from how ladies reply to training, metabolize vitamins and minerals, and regulate system temperature and hydration concentrations. In other text, my fueling requirements and ability to get well from exercise routines may possibly alter based on whether I’m in a small-hormone stage or a high-hormone stage. 

In an endeavor to get to the bottom of why my physical fitness was trapped in the doldrums, I tracked my period for two months working with two apps: Clue and FitrWoman.

According to experts, understanding how ladies working experience the menstrual cycle is elementary to sports activities and overall performance.

Let’s back again up for a minute. You may possibly don’t forget from biology course that there are two phases of the menstrual cycle. The initial stage is the follicular stage, which kicks off when a female starts her period: the system prepares to release an egg from an ovary and starts to rebuild the uterine lining. Commonly, hormones are small for the duration of this period but commence to rise. Ovulation occurs mid-cycle, when the egg is launched. This marks the end of the follicular stage and the starting of the luteal stage, when hormone concentrations are usually high and the system prepares to both accept a fertilized egg and aid a pregnancy, or the system gets all set to shed the uterine lining. 

In the previous couple many years, scientists have begun to dig further into sexual intercourse discrepancies in sports activities science, with a individual emphasis on the impact of the menstrual cycle. There is mounting anecdotal evidence that when you alter training protocols to the particulars of feminine physiology, athletes accomplish far better. The greatest endorsement for period tracking came last summer months, when it was unveiled that the U.S. Women’s National Soccer Team—who gained a historic fourth Earth Cup last July—tracked their cycles leading up to and for the duration of the match. The staff executed training, diet, restoration, and sleep approaches based on wherever each participant was in their cycle. Chelsea F.C. Gals (a women’s soccer club based in England), the Brisbane Lions Women’s staff (an Australian Soccer League women’s staff), and other individuals have also followed match.

While recognizing month-to-month fluctuations can be practical, period tracking is not a silver bullet. There is not enough high-high-quality research to build evidence-based recommendations, especially supplied women’s highly variable activities with their period. In a Twitter thread, Kirsty Elliot-Sale, an affiliate professor at Nottingham Trent College and a researcher on feminine physiology, cautioned: “We, the scientific local community, have not however achieved a consensus on the course or magnitude of adjustments that manifest for the duration of the menstrual cycle and as such it is difficult for us to information women’s activity on this foundation.” (In July of this 12 months, Elliott-Sale and her colleagues posted a meta-investigation of the research on the menstrual cycle and physical exercise overall performance in the journal Sporting activities Drugs, and called for additional investigation due to the fact of the inconclusive success.)

However, menstrual cycle tracking can be an possibility to empower ladies to value their very own physiology, states Dr. Ellen Casey, affiliate attending physiatrist in the Women’s Sporting activities Drugs Middle at the Hospital for Unique Surgical procedure in New York Town. “If it is genuinely accurate that chance of injuries and overall performance fluctuates across the menstrual cycle, we can both say, ‘That sucks,’ and not deal with it, or we can say, ‘This is interesting. Are there items we can understand from this? Can we harness these adjustments and train in particular techniques at particular periods?’” 

In the previous, most ladies have relied on pen and paper to retain tabs on their intervals, if they did at all. Today there is no lack of apps to help ladies comprehend their bodies far better. It’s all element of the booming “femtech” market place, broadly described as products and solutions, apps, and electronic solutions centered around women’s health and fitness and effectively-remaining. The category is projected to be value $50 billion by 2025, according to Frost and Sullivan, a internet marketing consulting business. 

While most period-tracking apps are geared toward ovulation and fertility, a expanding number like Clue and Flo allow ladies to log physical exercise and electrical power concentrations as effectively as more standard indications like cramps and cravings. Garmin and Fitbit also offer you period-tracking functions, so ladies can make notes on their cycle along with their runs, bikes, and swims. MyFlo implies different actual physical pursuits that may possibly be more suited to the current stage of your cycle. The application then types by way of your data and appears for patterns and developments.

FitrWoman, which is focused specially to active ladies, will take items a action additional: in addition to menstrual cycle and exercise tracking, it provides academic snippets on what’s happening in your body based on your current menstrual cycle stage, and provides approaches to mitigate those consequences. On the home screen, you can swipe by way of a couple slides and examine how hormonal fluctuations may possibly affect your physiology, training, and diet. There’s a connection to recipes, much too, which are tailor-made to aid training and restoration for the stage you are in. 

Just about every day, I opened the apps, clicked on the calendar (the principal hub in each apps), and claimed any symptoms I expert that day. In FitrWoman, I scrolled a single site and chose from 20 different indications.


Clue, on the other hand, teams indications into nine categories (bleeding, suffering, emotions, sleep, electrical power, cravings, digestion, psychological, and physical exercise). Just about every category has 4 options: like cramps, headache, ovulation, and tender breasts for suffering or joyful, sensitive, unhappy, or PMS for emotions. Just swipe and faucet to log the pertinent indications. I also have the selection to build personalized tags. Just about every month, I pointed out when my period started, its flow, and how long it lasted. The apps then predicted when my future period would commence.



At initial, chronicling every day indications was like commencing a brand-new puzzle. I was thrilled to dig in and figure out what all the pieces would reveal about my physiology. For case in point, I recognized that I normally feel wonderful in the follicular times involving the end of my period and ovulation, when my hormone concentrations are comparatively small. I’m joyful. I have a good deal of electrical power. And I feel robust for the duration of my runs and toughness periods, so I can force myself more durable. 

On the flip aspect, for the duration of the luteal phase I are inclined to feel flat, battle every day complications, and have significantly less electrical power and determination to do the job out. This can make feeling, since estrogen and progesterone concentrations are high, which can lead to bloating and exhaustion. I also want to consume all the sweet and salty foodstuff I can get my hands on for the duration of this time. “We know that cravings are possible prompted by elevated insulin resistance in this stage,” states Georgie Bruinvels, an physical exercise physiologist and the creator of FitrWoman. This can make blood-sugar concentrations more unstable. As an alternative of criticizing myself for remaining lazy and offering into my cravings, I was more proactive about fueling during the day to retain my blood sugar secure and switched up more durable exercise routines for yoga, swimming, or a rest day for the duration of this stage.

Both apps also permit ladies share data with their actual-lifestyle mentor. FitrWoman takes advantage of FitrCoach, a independent price-based system on which coaches can see wherever an athlete is in her menstrual cycle and which indications they’ve logged. It also sends a notification if an athlete hasn’t logged a period, which may possibly be a indication of amenorrhea, the absence of menstruation. Amenorrhea can have a long-expression impact on a woman’s health and fitness and sign the existence of a more substantial difficulty like the feminine athlete triad, or relative electrical power deficiency in activity (Purple-S). 

Because many ladies don’t chat brazenly about their menstrual cycle, this setup can be a way to aid these private discussions, states Adam St. Pierre, an ultrarunning mentor based in Boulder, Colorado. Previously, athletes would send him a text or email, or depart a note in their training log when they started their period or if they expert troublesome indications. “It wasn’t super scientific,” he states. “FitrCoach enables for more tracking, letting me make sure items are going effectively.” The equivalent setup for Clue is called Clue Connect: you can invite other individuals to watch your cycle, such as a mentor, husband or wife, family members member, or friend. The application will demonstrate them the dates for your previous, current, and predicted intervals, fertile home windows, and PMS. Other indications continue being private.

While logging indications and collecting data about my cycle was uncomplicated, figuring out what it all meant and how I could use it to my lifestyle wasn’t so straightforward. Both apps offer academic data about menstruation and popular indications, but the data is generic. I had to triangulate involving FitrWoman, physical exercise physiologist and diet scientist Stacy Sims’s reserve Roar (the go-to training and diet information for feminine athletes), and my very own working experience to ascertain which adjustments I could make and when. 

There is currently no uncomplicated way to action back again and get a macro-stage watch of my cycle and indications along with my training log in both application. While FitrWoman syncs with Strava, I can only see that data for an individual day, not on a weekly or month-to-month foundation. My essential exercise stats (length, rate, time, calories, elevation obtain, and so on.) automatically feed into my FitrWoman calendar and surface along with indications I’ve logged for that day. The data is not pushed to my Strava feed. As well as, I normally use TrainingPeaks, not Strava, to monitor my exercise routines, and proper now the application does not sync with TrainingPeaks. So I had to manually bounce back again and forth involving all the apps, producing it more durable to see developments and method the in general photograph of my health and fitness and overall performance. Bruinvels states FitrWoman options to develop a increased-stage watch of the data over a for a longer period time period and overlay it with training data. It may possibly also transfer toward predicting when indications are possible to occur based on former cycles. (The timeline for these developments is unclear.)

For its element, Clue does commence to review your claimed data after you finish two cycles. It plots recurrent indications across each recorded cycle and predicts when you are possible to working experience them based on previous cycles. It also offers an overview: the regular length of a cycle, the regular length of a period, and the standard cycle length variation. Clue’s cycle investigation starts to get at the macro-stage insights I crave and provides the data points to commence piecing together the puzzle. 

Admittedly, I wished period tracking to be a fix, and to offer you me a prescriptive route back again to far better physical fitness and toughness. But it is under no circumstances that uncomplicated. I’m continue to in the method of parsing out the data and tests different adjustments to get back again on monitor. 

Nonetheless, the straightforward act of noticing how I felt each day gave me a framework to interpret the alerts my system was sending. As an alternative of berating myself for a undesirable run or deficiency of electrical power for the duration of toughness exercise routines, I can place those exercise routines into context: Where am I in my cycle? What is going on with my system that may possibly make me feel this way? Need to I hope to feel good right now? Now I have a plausible rationalization for how I feel, placing a stop to some of the 2nd-guessing going on in my head.

“There’s no element of the cycle that’s adverse,” Sim states. “It’s about getting recognition of how you are across your cycle” and mastering to do the job with that. 

If you want to just take a peek underneath the hood and comprehend your menstrual cycle and how it influences you, listed here are some strategies to get you started.

How to Commence Monitoring Your Period

Demystify Your Cycle

Regardless of whether you use an application, a physical fitness tracker, or pen and paper, the initial action is to commit to tracking your menstrual cycle and ascertain its length. “Not every woman’s period is a textbook 28 times,” Sims states. Cycle length can range enormously from female to female, and even fluctuate from month to month. Even ladies at the similar stage of their cycles can have vastly different activities and indications, so it is essential to comprehend the affect of hormones in your very own system. 

Sims also recommends working with an at-home ovulation predictor package to ascertain when you are ovulating, especially if your application does not offer this data. (Clue does. FitrWoman does not.) This will inform you more specifically when you are moving into the increased-hormone luteal stage of your cycle. 

If you are getting hormonal start handle, it is a minor more complicated. For IUD consumers, you continue to working experience normal hormonal fluctuations, even if you don’t get a period, and can monitor your cycle and come across your month-to-month patterns. However, if you are on blended hormonal start handle, you don’t working experience the similar high- and small-hormone phases, since the contraceptive provides secure concentrations of estrogen and progesterone for 3 months out of every month. “You can monitor, but you are not going to have the similar reward as if you were working with your normal cycle,” Sims states. While you may possibly establish times when you feel good and undesirable, the complete strategy of using precise approaches for high-hormone compared to small-hormone phases does not use.

Observe Designs and Trends 

Sims recommends tracking your cycle for at least 3 months. This will commence to give you enough data so that you can commence to see developments. “If you monitor for a person or two months, what you working experience may possibly just be an off day,” she states. “But if it comes about 3 periods, then you know there may possibly be a actual pattern.” Overlay this data with your training log to spot connections involving the menstrual cycle and exercise routines and races. 

While the research is not quite robust enough however to make typical recommendations, merely raising your system literacy is helpful. Ross, the British isles-based physiologist, states that when you are in tune with the actual physical and psychological working experience of your cycle, you may possibly be more confident in organizing your training, diet, and restoration, which can get rid of a good deal of stress.

Change, Change, Change

Once you recognize patterns, commence to dial in your training and diet. “It does not have to be prescriptive like, ‘I’m in a small-hormone stage so I’m going to do high-depth training this day, this day, and this day,’” Sims states. As an alternative, use those patterns as alerts for when to ramp up pursuits or just take items down a notch. 

For case in point, for the duration of the high-hormone stage when ladies are possible to feel flat physiologically, it is not the greatest time to do the job tough. As an alternative, emphasis on procedure like managing drills. “With drills, you get the neuromuscular stimulus when the system is exhausted. Then, when you do the similar drills when hormones are more exceptional, you will accomplish that significantly far better,” states Sims. 

While “listen to your body” feels like cliché advice, it is continue to a good mantra. Each and every woman’s working experience is different across her cycle, and there’s no a person-measurement-fits-all template. Pay notice to what’s happening and make acceptable adjustments based on your private working experience.
