Musculoskeletal complaints such as joint stiffness, tendon pain, reduced mobility and slower recovery become increasingly common during perimenopause.
While these symptoms are often attributed solely to ageing, research suggests hormonal changes (particularly the decline and fluctuation of estrogen) significantly influence connective tissue health, musculoskeletal function and injury risk in women over 40.
At the same time, lifestyle factors such as low protein intake, inadequate recovery, low energy availability, and reduced resistance training may further contribute to declining connective tissue health and increased susceptibility to injury.
Understanding how these physiological changes affect the body is important for maintaining mobility, strength, recovery capacity and long-term musculoskeletal health.
Understanding Tendons, Ligaments and Cartilage
Tendons, ligaments and cartilage are all forms of connective tissue, but each serves a distinct role within the musculoskeletal system.
Tendons
- Tendons connect muscle to bone and transmit force generated by muscles to produce movement.
- Healthy tendons must tolerate both load and repetitive stress.
- Tendons are composed primarily of collagen, which provides structural strength and stiffness.
Ligaments
- Ligaments connect bone to bone and contribute to joint stability by limiting excessive movement.
- Ligament integrity is important for maintaining joint alignment and reducing injury risk.
Cartilage
- Cartilage provides cushioning within joints and assists with shock absorption and smooth joint movement.
- Unlike tendons and ligaments, cartilage has a limited blood supply, which can contribute to slower healing and degenerative changes over time.
Tendons, ligaments and cartilage all rely heavily on healthy collagen structure, appropriate mechanical loading, adequate nutrition and recovery for optimal function.
The Role of Estrogen in Connective Tissue Health
Estrogen has widespread effects on connective tissue metabolism and musculoskeletal physiology.
Research suggests estrogen influences:
- collagen production and repair
- tendon and ligament stiffness
- tissue hydration
- inflammation regulation
- muscle repair and recovery
- neuromuscular function
During perimenopause, declining estrogen levels contributes to altered collagen metabolism and reduced connective tissue resilience.
Research shows lower estrogen levels are associated with:
- increased tendon stiffness
- reduced collagen production
- decreased tissue elasticity
- impaired recovery from mechanical loading
- increased perception of joint pain and stiffness
These changes may partially explain why women often report increased musculoskeletal symptoms during the menopausal transition, even in the absence of major changes in physical activity levels.
Muscle Mass, Joint Stability and Injury Risk
Age-related muscle loss may accelerate during perimenopause due to hormonal changes, reduced anabolic sensitivity and inadequate resistance training.
Muscle tissue plays an essential role in supporting joint stability and reducing mechanical stress placed on tendons, ligaments and cartilage.
Loss of muscle mass and strength may contribute to:
- reduced joint stability
- altered movement mechanics
- increased tendon loading
- higher injury risk
- impaired balance and functional capacity
Research consistently supports resistance training as one of the most effective interventions for improving connective tissue function and maintaining musculoskeletal health in ageing populations.
The Impact of Low Energy Availability
Low energy availability occurs when energy intake is insufficient to support both exercise demands and normal physiological function.
This can occur in women who:
- chronically restrict calories
- under-consume carbohydrates
- perform excessive cardiovascular exercise
- fail to adequately fuel training sessions
- maintain prolonged dieting behaviours
Low energy availability has been associated with impaired recovery, increased injury risk, reduced collagen production and altered hormonal function.
Inadequate protein intake may further compromise:
- muscle protein synthesis
- connective tissue repair
- tendon recovery
- immune function
- overall recovery capacity
For women over 40, chronic under-fuelling combined with high training loads places additional stress on connective tissue already affected by hormonal changes.
Resistance Training and Connective Tissue Adaptation
Connective tissue responds to mechanical loading.
Progressive resistance training has been shown to stimulate adaptations in:
- muscle tissue
- tendon stiffness and capacity
- bone density
- neuromuscular coordination
- functional strength
Complete rest or prolonged inactivity is generally not beneficial for connective tissue health unless directed by a medical specialist.
Tendons and ligaments require mechanical stimulus to maintain capacity and structural integrity.
Nutritional Strategies to Support Joint Health
Protein Intake for Joint Health After 40
Adequate protein intake is essential for:
- muscle maintenance
- connective tissue repair
- recovery from exercise
- collagen production
Protein requirements increase with age due to anabolic resistance. This means the body becomes less responsive to the stimulus provided by protein intake and resistance training, making it harder to maintain and build lean muscle mass.
Older adults often require a higher protein intake to effectively support tissue repair, recovery and the maintenance of lean muscle mass.
Collagen Supplementation for Connective Tissue Health
Collagen supplementation has gained attention for its potential role in supporting connective tissue health.

Research suggests collagen supplementation, particularly when combined with resistance training, may help support tendon integrity, joint function and connective tissue adaptation.
Collagen supplementation may provide additional support for women experiencing increased joint stiffness, tendon discomfort or reduced recovery capacity during perimenopause and menopause.

Creatine and Tendon Health After 40
Creatine supplementation is most commonly associated with improvements in strength, lean muscle mass and exercise performance; however, emerging research suggests it may also play a supportive role in musculoskeletal and connective tissue health.

By improving muscle strength and training capacity, creatine may indirectly help reduce stress placed on joints, tendons and ligaments through improved muscular support and joint stability.
Research also suggests creatine may assist with:
- recovery from mechanical loading
- cellular hydration
- inflammation regulation
- preservation of lean muscle mass during ageing
These factors may be particularly relevant during perimenopause and menopause, when hormonal changes can contribute to declining muscle mass, reduced recovery capacity and increased musculoskeletal discomfort.
Omega-3 Fatty Acids for Joint Health
Omega-3 fatty acids play an important role in inflammation regulation and may help support overall musculoskeletal and joint health.
Chronic low-grade inflammation tends to increase with ageing and is also influenced by hormonal changes during perimenopause.
Elevated inflammation can contribute to joint discomfort, stiffness, slower recovery and increased musculoskeletal pain sensitivity.
Research suggests adequate omega-3 intake may help:
- support joint comfort and mobility
- reduce exercise-induced inflammation
- assist recovery processes
- support muscle function
- improve overall musculoskeletal health
Exercise Recommendations for Women Over 40
A comprehensive exercise approach for connective tissue and joint health should generally include:
- resistance training
- mobility and range-of-motion work
- cardiovascular fitness training
- impact or loading activities where tolerated
Avoiding impact or loading is not necessarily protective and may contribute to declining tissue capacity over time.
When Persistent Pain Requires Further Assessment
Seek medical advice if you experience:
- swelling
- sharp pain
- joint instability
- significant weakness
- progressive worsening
- inability to tolerate normal loading or movement
While mild stiffness and discomfort may occur, persistent pain shouldn’t be ignored.
Conclusion
Joint stiffness, tendon pain and slower recovery are increasingly common during perimenopause, but they are not simply the result of “getting older.”
With the right training, nutrition and recovery strategies, it is possible to support connective tissue health, maintain strength and improve long-term musculoskeletal function.
The SBF 4 Week Challenge is designed specifically for women over 40. It combines evidence-based strength training, nutrition and recovery strategies to support the physiological changes that occur during perimenopause and menopause.
