About this trial
The goal of this randomised controlled trial is to investigate the effects of and compare two modes of physical exercise (strength training and high-intensity aerobic exercise) to unchanged physical activity on vasomotor symptoms (hot flushes) in postmenopausal women. The main question it aims to answer is the effect of 15 weeks of strength training vs high intensity aerobic training vs unchanged physical activity on frequency and severity of hot flushes. Participants will be randomised to:
1. strength training 2. high-intensity aerobic training 3. untreated control group.
Researchers will compare strength training, high-intensity aerobic training and untreated control group to see if training can reduce hot flushes.
