Overview
Brief Summary
Today's women will live more than a third of their lives after menopause, i.e. with a changed hormonal and metabolic state. Vasomotor symptoms like hot flushes and sweating are reported by about 75% of all women around menopause and may impair well-being, mental state, daily activities and night sleep. Vasomotor symptoms are less prevalent in women who participate in regular physical exercise. It is, however, still uncertain if physical exercise reduces vasomotor symptoms.
The purpose of this randomized controlled study is to establish possible beneficial health effects from 15 weeks of supervised resistance training (RT) on postmenopausal women. End-points include effects from RT in postmenopausal women on
- clinical outcomes (number and severity of vasomotor symptoms, Health-Related quality of Life (HRQoL), Body Mass Index (BMI), abdominal height, muscle strength and mass, browning of fat),
- diagnostic variables (production of myokines as irisin, immunological markers) and
- genetic variables (length of telomeres).
The control group will be offered resistance training after the intervention period.
Detailed Description
The first phase is planned as a pilot-study including 20 women participating for 15 weeks. Thereafter an evaluation of the sample size and the study methodology will be made.

Eligibility Criteria
Inclusion Criteria
- •Postmenopausal women who had at least 28 moderate to severe hot flashes per week during a screening period of two weeks.(Postmenopausal, i.e. had their last menstrual bleeding at least 12 months ago or have increased gonadotrophic hormones showing they are postmenopausal.)
- •At lest 45 years of age
- •Good physical health and physical ability to take part in organized resistance training or other training at least three times per week.
- •Ability to speak and read Swedish
- •Freely informed consent for participation
Exclusion Criteria
- •Physically active more than 75 minutes of intense exercise per week or more than 150 minutes of low intensity activities
- •Hb \<110 g/l
- •Blood pressure \>160 systolic and/or \>100 mmHg diastolic pressure
- •Ongoing usage or use during the last two months of hormone therapy aimed for hot flashes
- •Treatment with psychopharmacological drugs (e.g SSRI or SNRI) or other treatment with a possible effect on menopausal symptoms
- •Uninvestigated or unstable disease that could affect presence of flushes (e.g thyroid disease)
- •Other medical condition that is judged inappropriate to combine with physical activity or participation in the study.
Outcomes
Primary Outcomes
Change in frequency of hot flushes per 24 h
Time Frame: Baseline to 15 weeks of intervention/control group
