Tendons, Ligaments and the Female Athlete: Training to Stay Injury-Free
Bones and muscles get all the attention. The stuff that actually holds you together, your tendons and ligaments, gets ignored until one of them starts screaming. Then you are hobbling around with a sore Achilles or a cranky knee, wondering what you did wrong.
Here is the part that rarely gets said. Your connective tissue behaves differently because you are a woman, and it changes across your cycle and again at menopause. Understand that, and you can train in a way that keeps you in one piece.
This is the injury-prevention piece most women never get told.
Your tendons and ligaments are hormonally sensitive. Oestrogen changes how stiff, springy and injury-prone they are, and it shifts across your cycle and falls at menopause.
This is not a reason to be scared of training. It is a reason to train your connective tissue deliberately, load it patiently, and stop treating niggles as bad luck. Tendons are trainable. They just work on a slower clock than muscle.
Why women's tendons are different
Tendons and ligaments are mostly collagen, and collagen is influenced by oestrogen. That single fact explains a lot.
Oestrogen affects how much collagen you make and how stiff your tendons and ligaments are. When oestrogen is high, tissues tend to be a little laxer and more flexible. When it is low, they tend to be stiffer and, over time, less resilient. Because your oestrogen is never static, your connective tissue is never quite static either.
Add to that some plain structural differences. Women tend to have wider hips, different knee alignment and different muscle activation patterns, all of which change how force travels through the knee and lower limb. It is why women suffer certain injuries, the anterior cruciate ligament tear being the headline one, far more often than men. Depending on the sport, women tear their ACL somewhere between two and eight times as often.
There is one more thing about tendons that matters for everyone, women and men alike, but it stacks on top of the hormonal picture. Tendons have a poor blood supply and a slow rate of turnover. They renew themselves far more slowly than muscle does. That is why they take so long to build and so long to repair. When you throw the hormonal sensitivity of female tissue on top of an already slow-adapting structure, you get a system that rewards patience and punishes impatience more than almost anything else in your training.
None of this makes you fragile. It makes you specific. And specific means trainable, once you know what you are training for.
Your cycle changes your injury risk
This is the part that surprises people. Your risk of certain injuries is not the same every day of the month.
Around ovulation, in the days when oestrogen peaks in the first half of your cycle, your ligaments become a little laxer. Reviews of the research link this pre-ovulatory, higher-oestrogen window to a greater risk of ACL injury. Your joints are marginally looser, and under a hard cut, land or twist, that can be the difference.
Now, read this the right way. It does not mean you cancel training around ovulation or live in fear of a phase of your own cycle. The effect is a shift in risk, not a guarantee, and being fit, strong and well-coordinated matters far more than the calendar. What it does mean is worth knowing: your body is not a fixed machine, and a bit of awareness helps. If you do sports with sharp changes of direction, it is one more reason to make sure your strength and landing mechanics are rock solid all month round.
The empowering version of this is simple. You cannot change your hormones, but you can change how strong and controlled your legs are when you land. That is where the real protection lives.
What menopause does to your tendons
Fast forward to perimenopause and menopause, and the story flips from laxity to stiffness.
As oestrogen falls for good, tendons tend to get stiffer, less springy and slower to heal. This is a big reason women in their forties and fifties suddenly collect injuries that seem to come from nowhere. Achilles trouble, plantar fasciitis, tennis elbow and frozen shoulder all become more common around the menopause transition, and they hang about longer than they used to.
If you have found that niggles now take weeks to settle when they used to clear in days, this is why. It is not you being soft or old. It is your tissue healing more slowly with less oestrogen to help it. The response is not to stop loading, which makes tendons weaker still. It is to load smart, be patient, and give the tissue the time and the stimulus it needs.
There is a cruel irony here worth naming. The stiffer, less resilient tendons of menopause are best protected by exactly the thing many women shy away from at that age, which is proper strength training. Load is medicine for tendons. A tendon that is regularly and sensibly loaded stays far more robust than one that is wrapped in cotton wool. So the instinct to go gentle and do less as things start to niggle is precisely backwards. Do less running if you must, but do more, well-managed strength work, not less.
The mistakes that get women injured
Most tendon and ligament injuries are not freak accidents. They are the predictable end of a few common habits.
Jumping your mileage, adding hills, or piling on intensity all at once because you feel motivated. Tendons adapt slowly and hate sudden change. A big, fast jump in load is the classic recipe for tendinopathy. Progress in small steps your tissue can keep up with.
Running and cycling do not build strong, robust tendons on their own. Strength training is what gives your connective tissue the capacity to handle load. Endurance women who never lift are running on tendons that have never been properly built up.
Training through a grumbling tendon and hoping it goes away. Early tendon pain is a message. Caught early and managed, it settles. Ignored for months, it becomes a stubborn, career-limiting problem.
Never training how you land, cut and stabilise. Neuromuscular work, the drills that teach your body to absorb force well, measurably lowers injury risk, especially at the knee. Most women skip it entirely.
Three principles protect connective tissue:
- Load it. Tendons get strong by being loaded, not rested. Strength training is non-negotiable.
- Be patient. Tendons adapt over months, not weeks. Progress slowly and let the tissue catch up.
- Control it. Train how you land and stabilise, so force goes where it should.
Do these three and you build tissue that copes with everything your training throws at it.
How to actually build strong tendons
Here is the practical toolkit. It works whether you are trying to prevent injury or come back from one, though a painful tendon should be guided by a good physio. A quick word on that last point. If a tendon is genuinely painful, not just a bit stiff, a physio who works with runners is worth their weight in gold. They can tell you how much to load and how much to back off, which is the exact judgement that is hardest to make on your own when you are keen to keep training. Everything below sits alongside that guidance, not instead of it.
Two or three strength sessions a week, built up sensibly over time, are the backbone of injury-proof tendons. Squats, hinges, calf work, single-leg strength. Real load, progressed gradually, is what tells your tendons to get stronger.
For a grumpy tendon, slow, heavy, controlled strength work and isometric holds, where you contract without moving, are among the best-evidenced ways to build capacity and calm pain. Slow and deliberate beats fast and flashy here.
Springy, elastic work like skipping and low-level plyometrics trains tendons to store and release energy, which keeps them robust and powerful. Introduce it gradually, well after you have a strength base, not as a starting point.
There is promising evidence that taking around 15 grams of collagen or gelatin with a source of vitamin C, roughly 30 to 60 minutes before loading the tendon, supports collagen synthesis. Studies in female athletes have shown it can enhance tendon adaptation. It is a bonus on top of good training and enough overall protein and food, not a substitute for them.
Putting it in your week
None of this needs to swallow your training. It slots around it. Here is a realistic shape.
- Two strength sessions a week, each including some single-leg and calf work, progressed a little at a time.
- Five to ten minutes of control work tagged onto a warm-up a couple of times a week, practising how you land and balance.
- A gentle sprinkle of bounce, like skipping, once you have a few weeks of strength behind you.
- Sensible load progression in your running and riding, nudging volume up in small steps rather than leaps.
- Prompt attention to niggles, backing off and managing them early rather than pushing through.
That is maybe twenty extra minutes a week of dedicated work, plus a bit more patience with your progression. It is a tiny investment against the weeks or months an injury steals.

Get the routinePatience is the whole game
If there is one thing to hold onto, it is that tendons run on a slow clock. Muscle can strengthen noticeably in weeks. Tendons take months. That mismatch is exactly why women get hurt. Your muscles and your fitness race ahead, your enthusiasm follows, and your connective tissue is left trying to catch up to a load it was never built up to handle.
So the winning move is almost boringly simple. Build strength consistently. Progress your training in small steps. Respect the early warning signs. Add your control and bounce work once the base is there. And through perimenopause especially, expect things to take a little longer and plan for it rather than fighting it.
It is also worth saying that this work compounds. The strength and control you build to protect your tendons makes you a better athlete across the board. You run more economically, you hold form when you are tired, you climb better and you finish stronger. Injury prevention and performance are not two separate projects. They are the same project, and connective tissue is where a lot of it quietly lives.
Do that, and you become the woman who just keeps training while others are stuck in the injury cycle. Not because you are lucky. Because you built yourself to last. Brick by brick.
- ✓You keep picking up tendon niggles that take forever to settle
- ✓Injuries have crept in as you have moved through your forties or fifties
- ✓You run and ride but have never done proper strength or control work
- ✓You want a plan that builds you up without breaking you down
If that is you, injury-proofing is exactly the kind of thing I build into a plan.
