Most of what we know about training bodies, we learned from studying men's. Here's where that actually costs female athletes — and what's finally changing.
Sports science has transformed how athletes train over the past two decades. Better programming, better recovery, better injury prevention. But almost all of it was built on a foundation with a specific shape: male participants, male physiology, male-derived conclusions applied to everyone.
Female-only studies remain rare, and in mixed-gender research women make up only a little over a third of participants on average. Findings then get extrapolated to women without the data to support the leap.
That's not an abstract complaint. Here's what it looks like in practice.
Where the Gap Actually Shows Up
Four places the research already tells us women differ — and the advice hasn't caught up.
Knee injuries
The clearest example. Research on non-contact ACL injuries finds female athletes are roughly 3.5 times more likely to tear an ACL than male counterparts, driven by differences in landing mechanics, hamstring-to-quadriceps recruitment and neuromuscular control.
The encouraging half: those factors are trainable. A meta-analysis of randomized controlled trials found neuromuscular training reduced overall knee injury risk by 22% and ACL injury risk by 50% in female team sport athletes — with adherence above 75% mattering more than programme sophistication.
Fuelling
Protein guidance is largely built from studies of steady endurance work or straightforward resistance training in men. A study measuring protein requirements in active females performing variable-intensity intermittent exercise — the stop-start pattern that describes soccer — found requirements of roughly 1.4 to 1.7g per kilogram daily, above what many female team sport athletes report eating.
Energy availability
The IOC consensus statement on Relative Energy Deficiency in Sport documents consequences for bone health, menstrual function, immune function and performance when intake doesn't cover training demand. Awareness among coaches and athletes remains low.
Even footwear
A systematic review of minimal footwear transitions found women are at greater risk of bone marrow oedema when switching than men, and recommends a more conservative transition. Almost no consumer guidance mentions it.
Four different domains, one pattern: where anyone has bothered to look specifically at women, they've found something the general advice missed.
Why the Differences Run Deeper Than Size
Not smaller men.
The instinct is to treat a female athlete as a scaled-down version of a male one. Bone density and geometry differ. Muscle architecture and fibre distribution differ. Hormonal cycling affects tissue laxity, thermoregulation, fuel use and recovery in ways men's physiology simply doesn't replicate.
Which means a nutrition protocol or an injury prevention programme optimised on male data isn't slightly off for women — it may be solving a different problem. And that's before accounting for psychology, motivation and the coping mechanisms that shape performance under pressure.
What's Being Done
The institutional money is finally starting to move.
Researchers have flagged this gap for years without the funding to close it. Good studies are slow and expensive, and commercial pressure has consistently favoured the men's game.
While much of the sport economy has concentrated on the profits of pro leagues and sports betting sites, Canada is among the national bodies now directing resources toward female-specific research instead — an area with no comparable commercial return but far greater impact on athlete health.
The clearest signal is the Global Alliance for Female Athletes, a partnership of national sports institutes set up to accelerate female athlete research and share it internationally. Founded by Australia, the United States, the United Kingdom and New Zealand, it expanded in August 2026 to include Canada, France, Germany, Japan and Switzerland, with the Canadian Olympic and Paralympic Committees joining together.
Alongside that, Canadian federal funding has gone to organisations working on participation and retention for women and girls — the ground-level end of the same problem. Multi-disciplinary teams have formed around specific questions, ACL injury among the most active.
How Long Until It Actually Helps
Years. But the direction has changed.
It took decades to accumulate the male-derived evidence base we have now. It would be unrealistic to expect a research programme started recently to deliver equivalent depth quickly, even fully funded.
Existing work isn't wasted — much of it provides a starting point rather than a blank page. But the shortcuts are smaller than anyone would like, and some questions genuinely need answering from scratch.
In the meantime, the practical stance for any female athlete is a slightly sceptical one: treat universal-sounding advice as provisional, pay closer attention to your own responses than to a generic protocol, and prioritise the things the female-specific research has already established — neuromuscular work for knee protection, eating enough for the training you're doing, and recovery that's actually programmed rather than hoped for.
What This Means for Your Own Training
The evidence that does exist is worth acting on.
-
Do the neuromuscular work. Landing mechanics, deceleration, single-leg control. The 50% ACL risk reduction figure is among the strongest findings in women's sports medicine, and it depends on consistency more than complexity.
-
Eat enough, particularly protein. Under-fuelling is the documented problem in this population, not over-fuelling. Our guide to what to eat after a workout at night covers the awkward evening-session version.
-
Programme recovery deliberately. See how many rest days a week you actually need, and how to speed up muscle strain recovery when something flares.
-
Strength train. Our guide to weight training for women covers the fundamentals.
-
Raise persistent changes with a clinician. Ongoing changes to sleep, appetite or menstrual cycle are worth a conversation with a doctor rather than self-management.
Why We Care About This
It's the same gap we were founded to close.
Goal Five exists because women's sport has been treated as an afterthought — in research, in funding, and in the gear itself. Kit designed for women rather than scaled down from a men's pattern is the same argument as sports science built on female participants rather than borrowed from male ones.
It's why we put 5% of profit toward expanding girls' access to the game, and why we started in the first place. You can read more on that thinking, and the athletes living it, over on Her Fifth Gear.
FAQs
What is the female athlete research gap?
The underrepresentation of women in sports science research. Female-only studies are rare, and women make up roughly a third of participants in mixed-gender research, so conclusions drawn largely from male data get applied to women without direct evidence.
Why do female athletes tear their ACLs more often?
Research points to differences in landing mechanics, hamstring-to-quadriceps recruitment and neuromuscular control, with non-contact ACL injury risk roughly 3.5 times higher than in male athletes. Neuromuscular training substantially reduces that risk.
Do women need different training programmes than men?
The principles of training are the same, but the specifics — injury prevention priorities, fuelling requirements, recovery needs — differ enough that female-specific evidence matters where it exists.
What is the Global Alliance for Female Athletes?
A partnership of national sports institutes founded by Australia, the US, the UK and New Zealand to accelerate and share female athlete research. It expanded in August 2026 to include Canada, France, Germany, Japan and Switzerland.
How long will it take to close the gap?
Years of sustained work. Existing research provides a starting point, but many questions need answering directly in female populations, and that takes time even with funding.
