More than 60 % of women experience hot-flashes during postmenopausal and 20 % have serious symptoms. Use of combined estrogen/progesterone therapy reduces hot-flashes effectively. In 2001, results from the randomized controlled WHI-study (Womens Health Initiative) showed increased risk for breast cancer and hearth-disease among users of combined estrogen/progesterone therapy. This reduced the use of combined estrogen/progesterone therapy. Many women seek alternative treatment for hot-flashes. They are often told that physical activity can reduce intensity and frequency of hot-flashes. The evidence for this advice is sparse. The primary hypothesis tested in the WHAT-study will be: Increased physical activity reduce frequency and intensity of hot-flushes among sedentary postmenopausal women with bothersome hot-flushes. The WHAT-study is designed as a pragmatic randomized controlled clinical trial. To answer the primary hypothesis we will need approximately 500 participants. The logistic in a pragmatic trial of a complex intervention are complicated and we decided to first run a pilot study with 50 participants as a feasibility study. The pilot gives us opportunity to gain experience with possible problems like withdrawals and injuries.
