Staying active at “that time of the month”

Observe me on Twitter @RobShmerling

This previous August, her exuberance, emotion and enthusiasm had already made Fu Yuanhui essentially the most well-known Chinese language athlete on the Olympics. After successful a bronze medal within the girls’s 100-meter backstroke with a private greatest, she almost exploded with pleasure: “I used to be so quick! I’m actually happy! I’ve already… expended my primordial powers!” Her interview went viral with thousands and thousands of hits worldwide.

Then she stated one thing actually surprising: she was having her interval. Noticing that the swimmer was grimacing after her relay group narrowly missed medaling, an interviewer requested if she had a stomachache. Yuanhui answered “It’s as a result of I simply received my interval yesterday, so I’m nonetheless a bit weak and actually drained. However this isn’t an excuse for not swimming properly.”

When the New York Occasions, NPR and different media retailers lined the story of the Chinese language swimmer who dared to say that she was having her interval as if it have been the superbly pure factor that it’s, they targeted on the truth that she’d violated a cultural taboo — certainly, it’s just about unprecedented for ladies in China to publicly point out menstruation. However, in addition they missed a possibility to counter the frequent false impression that menstruation impairs athletic efficiency or that it’s unsafe or inappropriate to swim whereas having your interval.

Menstruation and athletics

I recall classmates in highschool sitting out basketball apply as a result of that they had their intervals. I assumed it was simply because they weren’t feeling properly. In reality, many ladies have been advised they’re extra prone to be injured, much less prone to carry out properly, and that one of the best ways to deal with menses is to take it simple. Possibly. However the proof for every of those is weak.


A lot has been made in regards to the obvious elevated incidence of great accidents — ankle sprains, anterior cruciate ligament (ACL) tears and others — in feminine athletes in contrast with their male counterparts. Blaming it on “hormones” is frequent. A 1989 examine interviewed 84 feminine soccer gamers and located extra stories of accidents throughout the premenstrual interval and menstrual interval, particularly amongst these with premenstrual signs (resembling irritability or breast discomfort). A 2007 examine discovered that ACL accidents tended to happen extra typically throughout the first half of the menstrual cycle (within the week or two after the interval). A 2009 examine discovered that amongst eight wholesome volunteers, hamstring flexibility elevated on the mid-point of the menstrual cycle. That’s the purpose within the cycle that estrogen ranges are rising or at their highest.

So it’s potential that variations in feminine hormones by way of the menstrual cycle change the perform of bones, joints, tendons, or ligaments, and that these adjustments might have an effect on efficiency or probability of damage. Then once more, these research are merely observations of sure patterns — they don’t show a connection between phases of the menstrual cycle and damage. In reality, we don’t know for certain whether or not the section of the menstrual cycle actually has an necessary impact on tendency for damage. And if there may be an impact, it’s not clear what to do about it.

Athletic efficiency

Research discover inconsistent results on the influence of menstrual intervals on athletic efficiency. For instance:

  • a bunch of swimmers have been discovered to have poorer efficiency simply earlier than their intervals began, and improved instances throughout menstruation
  • cross-country skiers have been greatest simply after their intervals and after ovulation (which happens halfway between intervals)

in yet one more examine, power of handgrip and standing lengthy bounce distance have been greatest throughout menstrual intervals in contrast with different elements of the menstrual cycle.

A 1994 evaluation reviewing the accessible analysis concluded that in relation to having your interval, “…for most girls there isn’t any vital impact… medals have been gained and world information set in any section of the menstrual cycle.”

Even so, many ladies don’t really feel properly simply earlier than or throughout their intervals and it appears cheap that this might have an effect on athletic efficiency. Anybody who’s in ache, drained, or simply not as sharp as typical might not carry out at their highest potential. And in elite athletics (resembling Olympic occasions) wherein the distinction between a gold medal and final place could also be fractions of a second, absolutely feeling poorly might make an enormous distinction. A 2009 examine concluded that taking an anti-inflammatory medicine (known as diclofenac, a drug that’s just like ibuprofen) led to decreased menstrual cramps and improved train efficiency. In reality, some athletes attempt to keep away from the problem altogether: they take oral contraceptive drugs or different hormones to keep away from having their intervals throughout necessary athletic occasions.

The underside line

There’s a lot we don’t perceive in regards to the relationship between the menstrual cycle and athletic accidents or athletic efficiency in girls. It’s in all probability true that particular person components, together with total well being, kind of train, diploma of conditioning, and dietary standing matter greater than the section of the menstrual cycle.

Clearly, girls with premenstrual or menstrual signs might not really feel like exercising. However there isn’t any compelling proof that train or athletic actions needs to be averted or altered primarily based solely on what a part of the menstrual cycle you’re in. Good coaching might cut back the dangers of damage and improve efficiency rather more than attempting to time train round one’s intervals.

Many have counseled Fu Yuanhui for being so forthright about having her interval although it violated a longstanding taboo, however she is also counseled for avoiding the temptation in charge her interval for a disappointing efficiency.
