Declining Oestrogen and Tendon Pain in Active Women

If you’ve suddenly developed a sore Achilles, aching hips, stubborn hamstring pain, tennis elbow or a shoulder that no longer tolerates training the way it used to, you are not imagining it.

During peri-menopause, many women notice a sharp increase in tendon pain, stiffness & slower recovery. Research increasingly shows that fluctuating & declining oestrogen affects tendon structure, collagen turnover, recovery capacity & pain sensitivity.

For recreational athletes this can feel particularly frustrating. Training methods that worked for years may suddenly lead to irritation, overload & recurring injury.

The good news? Tendons are highly adaptable tissues. With the right loading, recovery, nutrition & hormone-aware approach, most women can continue to train successfully.

What is Tendinopathy?

Tendinopathy is a broad term describing pain and dysfunction in a tendon — the tissue that connects muscle to bone.

Historically, people used the term “tendinitis”, implying inflammation. We now know that most persistent tendon pain is not primarily inflammatory. Instead, it usually reflects a disrupted healing response & altered collagen structure within the tendon.

Common features include:

• Pain during or after loading

• Morning stiffness

• Reduced tolerance to exercise

• Local tenderness

• Loss of strength or “spring”

• Delayed recovery after training

Tendon pain often fluctuates. You may feel fine during exercise, then stiff & sore the next morning.

Oestrogen matters for tendon health

Tendons contain oestrogen receptors. Oestrogen helps regulate:

• Collagen synthesis

• Tendon hydration

• Tissue elasticity

• Recovery from loading

• Pain modulation

• Tendon remodelling

As oestrogen fluctuates and declines during perimenopause, tendon tissue becomes less efficient at adapting to load.

Research suggests menopause may lead to:

• Reduced collagen production

• Reduced tendon stiffness and resilience

• Slower healing response

• Reduced ability to tolerate repetitive loading

• Increased pain sensitivity

This helps explain why women in their 40s & 50s commonly experience new tendon problems despite no major change in training.

Why Recreational Athletes Are Especially Vulnerable

Athletic women often sit in a difficult middle ground:

• Enough training load to stress tendons

• Increasing recovery demands

• Hormonal instability

• Often insufficient recovery, sleep or fuelling

Add menopause-related sleep disruption, fatigue & altered recovery capacity, and tendons can become overloaded more easily especially when women increase training volume, intensity or shift events 

The classic pattern is: “I’ve trained for years & suddenly my body can’t tolerate what it used to.”

This is especially common in distance runners, hybrid athletes, e.g. CrossFit, Hyrox, racket sports players, lifters

Most Common Tendon Problems During Menopause

1. Achilles Tendinopathy

Especially common in runners & hybrid athletes. 

Symptoms:

• Morning stiffness in the Achilles

• Pain when running uphill

• Tenderness 2–6cm above heel

• Pain after speed work or plyometrics

2. Gluteal Tendinopathy

Symptoms:

• Pain on outer hip

• Pain lying on one side

• Pain climbing stairs

• Worse after sitting

• Pain during single-leg loading

3. Proximal Hamstring Tendinopathy (High Hamstring Pain)

This affects the hamstring tendon where it attaches high up onto the sitting bone.

Symptoms:

• Deep ache high in the glute or upper hamstring

• Pain sitting for long periods

• Pain during uphill running or sprinting

• Tightness that never fully resolves with stretching

• Pain during deadlifts or RDLs

• Morning stiffness

• Pain after rather than during training

A common description:

“It feels like a hamstring strain that never completely heals.”

4. Rotator Cuff Tendinopathy

Often aggravated by lifting & upper body training.

Symptoms:

• Pain reaching overhead

• Night pain

• Pain pressing or pulling

• Reduced shoulder strength

5. Patellar Tendinopathy

More common in jumping, sprinting and strength athletes.

Symptoms:

• Pain below kneecap

• Worse with stairs, jumping or squats

• Stiffness after inactivity

6. Tennis / Golfer’s Elbow

Often linked with gripping, lifting and repetitive upper body work.

Symptoms:

• Elbow pain during gripping or pulling

• Pain carrying weights

• Pain typing or using a mouse

• Reduced grip strength

Common Signs Your Tendon Pain May Be Menopause-Related

• Multiple tendon sites becoming painful at once

• Increased morning stiffness

• Pain worsening during late perimenopause

• Slower recovery between sessions

• Tendons feeling “fragile”

• Symptoms fluctuating with menstrual cycle changes

• Tendon pain alongside sleep disturbance, hot flushes or fatigue

Importantly, not all pain during menopause is “just hormones”. Persistent pain should still be assessed to rule out:

• Tendon tears

• Osteoarthritis

• Autoimmune disease

• Rheumatological conditions

• Stress fractures

How to Prevent Tendinopathy During Menopause

1. Respect recovery more than you used to

One of the biggest mindset shifts for midlife athletes:

Recovery becomes training.

Poor sleep, under-fuelling & excessive intensity dramatically reduce tendon tolerance.

Prioritise:

• Sleep quality

• Protein intake

• Recovery days

• Stress management

• Progressive loading

2. Avoid “weekend warrior” loading spikes

Tendons hate sudden changes.

Big increases in:

• Mileage

• Plyometrics

• Hill running

• Hyrox/CrossFit volume

• Heavy lifting frequency

…are common triggers.

Aim for gradual progression.

A useful guide: Increase total weekly load by no more than approximately 5–10% when symptoms are present.

3. Strength train consistently

Progressive resistance training is one of the best evidence-based tools for tendon health.

Key principles:

• Heavy slow resistance

• Controlled tempo

• Consistency

• Progressive overload

• Patience

4. Fuel properly

Under-fuelling is common in active midlife women.

Low energy availability impairs:

• Collagen synthesis

• Recovery

• Muscle maintenance

• Hormonal health

Athletes should prioritise:

• Adequate protein

• Carbohydrates around training

• Omega-3 fats

• Vitamin D

• Calcium

• Overall energy intake

5. Consider menopause support where appropriate

Whilst education and exercise are consistently shown to be the most effective approach to managing, emerging research evidence suggests menopausal hormone therapy (HRT/MHT) may positively influence tendon health in some women. This is highly individual and should be discussed with a qualified menopause specialist or GP. HRT is not a standalone treatment for tendinopathy — but for some women it may support overall musculoskeletal health.

Exercises, Stretches & Training Approaches to Avoid

One of the biggest myths around tendon pain is “If it feels tight, stretch it.”

In reality, many tendons become more irritated when placed under excessive compression, especially when combined with load.

The goal is not to avoid movement — it is to avoid repeatedly aggravating the tendon while progressively rebuilding load tolerance.

Tendon-Specific Exercise & Stretch Guidance

1. Gluteal Tendinopathy

Common aggravators:

• Sitting cross-legged

• Standing with hip dropped to one side

• Sleeping on affected side

• Deep hip adduction positions

Stretches often best avoided during flare-ups:

• Pigeon stretch

• Figure-4 stretch

• Deep glute stretches

• Aggressive ITB foam rolling

Exercises to modify temporarily:

• Curtsy lunges

• Excessive crossover drills

• High-volume lateral plyometrics

Better options:

• Glute bridges

• Split squats

• Step-ups

• Controlled single-leg work

• Band walks

2. Achilles Tendinopathy

Stretches to avoid during reactive flare-ups:

• Aggressive calf stretching off a step

• Forced dorsiflexion mobility drills

Exercises to modify:

• Excessive skipping

• Sprint intervals

• High-volume box jumps

• Hill sprints

Better options:

• Mid-range calf raises

• Bent-knee calf raises

• Isometric calf holds

• Heavy slow calf loading

Important for insertional Achilles pain: Avoid dropping the heel below neutral initially.

3. Proximal Hamstring Tendinopathy

This tendon strongly dislikes compression under stretch.

Stretches commonly aggravating:

• Toe-touch hamstring stretches

• Deep forward folds

• Seated hamstring stretches

• Long-duration yoga hamstring stretching

Exercises to modify temporarily:

• Sprinting

• Hill repeats

• Deep Romanian deadlifts

• Aggressive kettlebell swings

• Long-stride running

Better options:

• Bridge holds

• Isometric hamstring loading

• Short-range hinges

• Controlled RDL progression

• Step-ups

4. Patellar Tendinopathy

Exercises to modify during flare-ups:

• High-volume jumping

• Repeated tuck jumps

• Deep jump squats

• Max-effort plyometrics

Better options:

• Spanish squats

• Isometric wall sits

• Tempo squats

• Leg press

• Step-downs

5. Rotator Cuff Tendinopathy

Movements to modify:

• Repeated upright rows

• Heavy behind-the-neck pressing

• High-volume kipping

• Aggressive overhead volume

Better options:

• Landmine press

• Controlled rowing

• Scapular stability work

• Tempo pressing

• Band external rotation work

6. Tennis / Golfer’s Elbow

Exercises to modify:

• Excessive pull-up volume

• Heavy repetitive gripping

• High-volume kettlebell gripping

• High-rep Olympic lifting

Better options:

• Isometric grip work

• Eccentric wrist strengthening

• Neutral-grip pulling exercises

Evidence-Based Management Strategies

Relative load management

Not complete rest. Completely unloading a tendon often makes it weaker. 

Instead:

• Reduce aggravating load temporarily

• Maintain tolerable movement

• Reload progressively

Heavy Slow Resistance Training

This is one of the most evidence-supported approaches for persistent tendinopathy.

Typical principles:

• Slow tempo

• Moderate-heavy load

• 2–4 sets

• 6–12 reps

• 2–3x weekly

Isometric exercises

Useful for pain modulation.

Examples:

• Wall sit holds

• Calf raise holds

• Split squat holds

• Long-lever bridge holds

These can reduce pain without excessive tendon compression.

Improve movement variability

Avoid:

• Sitting for prolonged periods

• Repetitive identical loading

• Excessive high-impact volume

Micro-movement throughout the day matters.

Nutrition & Lifestyle Factors That Matter

Many active women unknowingly undermine tendon recovery through chronic under-recovery.

Protein Intake

Collagen-containing tissues require adequate amino acids.

Most active midlife women likely benefit from:

Approximately 1.6–2.2g protein/kg/day depending on training load and goals.

Aim for:

• 25–40g protein per meal

• Post-training protein intake

• Consistent intake across the day

Vitamin D

Low vitamin D is associated with:

• Musculoskeletal pain

• Reduced muscle function

• Poor recovery

This is particularly relevant in the UK due to low sunlight exposure.

Women with recurrent tendon pain may benefit from discussing vitamin D testing with their GP.

Omega-3 Fats

Omega-3s may help support:

• Recovery

• Pain modulation

• General musculoskeletal health

Sources include:

• Oily fish

• Fish oil

• Algae supplements

Collagen Supplements

Evidence is still evolving, but some research suggests collagen or gelatin combined with vitamin C before loading may support collagen synthesis.

Commonly studied protocol:

• Approximately 15g collagen or gelatin

• With vitamin C

• 30–60 minutes before training

Not a miracle cure — but potentially a useful adjunct.

Sleep

Poor sleep reduces:

• Collagen repair

• Recovery capacity

• Pain tolerance

• Muscle recovery

Perimenopause-related sleep disruption can significantly worsen tendon symptoms.

Helpful strategies include:

• Consistent sleep schedule

• Morning daylight exposure

• Reduced evening alcohol

• Managing caffeine timing

• Cooling strategies if hot flushes are present

Stress Load

Psychological stress affects:

• Recovery

• Pain sensitivity

• Sleep

• Tissue healing

Many midlife women sit in chronic “high output” mode:

• Careers

• Caring responsibilities

• Training

• Poor sleep

• Life admin

Sometimes the tendon is not just overloaded by training — it is overloaded by life stress.

Alcohol & Recovery

Alcohol can negatively affect:

• Sleep quality

• Recovery

• Protein synthesis

• Connective tissue repair

Even moderate intake may impact recovery in women already struggling with menopause-related sleep disruption.

Tendon-Friendly Warm-Up Ideas

A good menopause-aware warm-up should:

• Increase tissue temperature gradually

• Improve tendon stiffness

• Reduce abrupt loading

Example 5–8 minute prep

Lower body

• Marching calf raises

• Walking lunges

• Mini-band lateral walks

• Step-downs

• Ankle pogo hops (if tolerated)

Upper body

• Band pull-aparts

• Scapular wall slides

• Controlled shoulder CARs

• Light rowing

What to Avoid Overall

• Complete rest - Tendons generally need load to recover.

• Aggressive stretching - Especially compressive stretching on irritated tendons.

• Constant high-intensity training - Menopausal tendons often tolerate consistency better than chaos.

• “No pain, no gain” - Persistent worsening pain is not a badge of honour.

A useful guide:

• Mild discomfort during exercise can be acceptable

• Symptoms should settle within 24 hours

• If pain escalates progressively, load is likely too high
