Effects of Estrogen on Muscle Gain During 12-weeks of Exercise in Post-menopausal Women (HER-MUSCLE)

2026년 5월 23일 업데이트: Mette Hansen

As females age and transition through menopause, the decline in oestrogen level profoundly affects skeletal muscle mass and function. HER-MUSCLE aims to unravel the mechanisms by which oestrogen enhances muscle growth, providing insights for targeted therapies to improve the health and physical function of postmenopausal females.

Focusing on postmenopausal females, an increasingly at-risk demographic, HER-MUSCLE addresses a critical gap in understanding how oestrogen influences muscle mass and function during anabolic (exercise) conditions.

The project involves:

  1. Clinical Trial: Postmenopausal females will receive either oestrogen or placebo, twelve weeks of exercise training to detect oestrogen regulatory role on muscle mass and function.
  2. Molecular Analysis: Advanced techniques will study the muscle microenvironment, focusing on muscle stem cells (MuSCs), fibro-adipogenic progenitors (FAPs), and other cells critical for muscle regeneration and maintenance.
  3. Mitochondrial Function assessed in vivo via magnetic resonance spectroscopy: The impact of oestrogen on mitochondrial health will be examined, exploring how it preserves mitochondrial function and ability to recovery and resist fatigue in response to muscle contractions.

Our preliminary data indicate that oestrogen can promote muscle protein synthesis. HER-MUSCLE aims to pave the way for novel therapeutic strategies to manage sarcopenia in postmenopausal women, ultimately leading to better health outcomes and enhanced well-being for this growing population segment.

Mitochondria Function in vivo measured as phosphocreatine recovery rate
기간: 12 weeks
The dominant foot will be attached to a pedal mounted on the patient bed and a dedicated 31P surface coil will be secured over the tibialis anterior muscle. The pedal is designed to allow dynamic contractions of the tibialis anterior muscle while changes in metabolites from the tibialis anterior muscle are acquired non-invasively with the 31P coil. Two protocols will be performed: Firstly, 10 repeated contractions (one per 3 sec with a load representing 30% of maximal force) will result in a depletion (30-40%) of phosphocreatine (PCr). The rate constant for PCr recovery over 10 min will be used as an index of in vivo mitochondrial function. Secondly, a total of 80 repeated contractions (one per 3 sec with a load representing 30% of maximal force) will be used to quantify muscle fatigue and concurrent changes in muscle metabolites and intracellular pH (based on the chemical shift between inorganic phosphate and PCr).

Mitochondria Function in vitro measured as maximal oxygen consumption
기간: 12 weeks

All measurements were performed in duplicate using an Oxygraph-2k (Oroboros, Austria), in hyperoxygenated chambers (250-450 nmol O₂/mL).

Respiratory Control Ratio was used to evaluate mitochondrial efficiency. It was calculated as the ratio of maximal ADP-supported respiration (with complex I + II substrates) to leak respiration. Leak respiration reflects oxygen consumption in the absence of ATP synthesis, when only substrates are present and no ADP is added.
