What female athletes can teach us about understanding the female body.
For a long time, sports science had a male problem.
Much of what we understood about training, performance and recovery came from research conducted predominantly on men. Female hormonal fluctuations were often treated as a complication in research.
That is changing.
We now know much more about female physiology, menstruation, energy availability and what happens when women train hard without adequately supporting their bodies.
Some of these conversations echo an idea that has existed in Traditional Chinese Medicine for centuries:
The body needs replenishment as much as it needs output.
Your period is part of the picture
When we exercise, we tend to think in outputs.
How fast did I run?
How much did I lift?
How far did I go?
But your menstrual cycle is information too.
When the body doesn’t receive enough energy to support both exercise and its physiological functions, menstruation can be disrupted.
In sports medicine, this is part of Relative Energy Deficiency in Sport (RED-S). Low energy availability can affect menstrual function, bone health, immunity, metabolism and performance.
A period that changes significantly or disappears during intense training is worth paying attention to.
A TCM view of training
Traditional Chinese Medicine looks at exertion and recovery through a different lens.
Two concepts appear frequently in discussions of female health:
Qi (氣) and Blood (血).
Qi broadly describes the body’s functional activity and vitality. Blood is associated with nourishment and has a particularly important relationship with menstruation.
These concepts don’t map directly onto modern biomedical definitions.
In TCM, intense exercise, inadequate nourishment, poor sleep and menstruation can all be considered within a wider picture of expenditure and replenishment.
It shifts the question from simply:
How much can my body do?
to:
Am I giving it enough to recover?
The uterus doesn’t work alone
In TCM, menstruation isn’t viewed as the responsibility of the uterus alone.
The Spleen system is associated with transforming nourishment into Qi and Blood.
The Liver system is associated with storing Blood and supporting the smooth movement of Qi.
The Kidney system is associated with reproduction, development and ageing.
And the uterus, known as 胞宮 (Bāo Gōng), sits within this wider network.
These systems aren’t direct equivalents of the anatomical spleen, liver and kidneys in modern medicine. They belong to the language and framework of TCM.
The principle is simple:
Your muscles aren’t training in one body while your reproductive system lives in another.
Women athletes need blood. Literally.
There is also a biomedical reason to pay attention to blood.
Iron deficiency is particularly relevant for female athletes. Iron is essential for producing haemoglobin, which carries oxygen around the body. Menstruation is also a source of iron loss, particularly for women with heavier periods.
Low iron stores can contribute to fatigue and reduced exercise capacity, sometimes before iron-deficiency anaemia develops.
Modern medicine can measure ferritin and haemoglobin.
TCM has its own distinct concept of Blood, with centuries of attention given to menstruation, nourishment and fatigue.
They aren’t describing the same thing. But both give us reason to pay attention to what the body uses, loses and replenishes.
Recovery is part of training
Sports culture celebrates output.
Train harder. Run further. Get stronger. Do it again tomorrow.
Recovery deserves the same attention.
Eating enough. Sleeping well. Resting. Replenishing what your body uses.
TCM has a useful word for this:
養 (Yǎng)
To nourish. To cultivate. To support.
You can’t keep asking the body to give without giving something back.
Train in the body you have
Periods can be inconvenient. They can arrive on race day. Cramps can show up when you’re supposed to be lifting. Energy can feel different across the month.
There is no universal menstrual-cycle training programme that works for every woman. The evidence doesn’t support rigid rules about how every woman should exercise during each phase.
Your own baseline is more useful.
Know your cycle. Know your energy. Know what’s normal for you.
Notice when something changes.
The UTERIFIC take
We don’t need to optimise every biological signal. We should understand more of them.
Modern sports science gives us energy availability, hormones, iron, muscle and recovery.
Traditional Chinese Medicine gives us another language: Qi, Blood, nourishment, movement and rest.
Together, they raise a bigger question about how we think about women’s bodies and performance.
Performance is only half the story. Replenishment is the other.
