The Impact of Female Hormones on Muscle Strength

Oestrogen, progesterone, and testosterone play vital roles in muscle health, and HRT may offer benefits in preserving muscle mass, improving strength, and addressing age-related changes. Read on to find out more. 

How do our hormones impact our muscle strength and health?

Oestrogen plays a role in preserving muscle mass, and its decline, particularly during menopause, may contribute to a decrease in muscle mass. It also influences collagen synthesis, providing structural support to muscles and connective tissues.

Progesterone has muscle-relaxing properties, especially during pregnancy, where it helps prevent uterine contractions. Hormonal fluctuations, including changes in progesterone levels, may also affect exercise performance, influencing factors like muscle coordination.

While present in smaller amounts in women, testosterone contributes to muscle protein synthesis, promoting the growth and repair of muscle tissues. Testosterone replacement in women with low levels can lead to increased lean muscle mass and improved muscle strength.

What are the benefits of Hormone Replacement Therapy on muscle strength?

Preservation of muscle mass: HRT, particularly with oestrogen, may help prevent age-related loss of muscle mass, contributing to improved muscle strength.

Enhanced exercise performance: HRT, including testosterone replacement, may contribute to improved muscle coordination and strength, potentially benefiting exercise performance.

Reduced risk of sarcopenia: sarcopenia, the age-related loss of muscle mass and function, may be mitigated with HRT, helping maintain muscle strength in postmenopausal women.

Optimising bone health: HRT, especially with oestrogen, can contribute to optimal bone health. Strong bones provide a stable framework for muscles, supporting overall musculoskeletal health.

Management of fatigue: HRT, by addressing hormonal imbalances, may help reduce fatigue and improve energy levels, positively influencing muscle strength.

Maintaining functional independence: preserving muscle strength through h HRT can contribute to maintaining functional independence and a higher quality of life, especially in ageing women.

The benefits of HRT on muscle strength are individualised, and responses may vary based on factors such as genetics, overall health, and lifestyle. The decision to use HRT should be made in consultation with a healthcare professional. They can assess an individual’s health history, discuss potential risks and benefits, and tailor the treatment plan accordingly.
