Fellow Flasher here and an ultra cyclist. Also writing a paper on menopausal symptoms and exercise. Endurance exercise definately increased both frequency and severity of HF amongst our ladies. But there are a variety of important physiologic changes that also happen at menopause thathave the potential of being a big deal as you age- such as the acceleration of the loss of lean muscle mass and bone mass. That loss is almost impossible to get back the older you are. Also menopause is strongly connected to increasing belly fat. We're finding that fat to be particularly dangerous to cardiovascular and brain health (and btw belly fat is strongly connected to flashing in non exercisers). Bottom line exercising at this time of your life is really important- both to maintain your muscles&bones and to reduce belly fat. And exercising will also improve your sleep and moods! It has its benefits when riding on a below-freezing day too! . Good health to you and happy pedaling!
