Exercise Training and Thrombotic Risk in Post-menopausal Women

Susceptibility to Thrombosis in Post-menopausal Women- Influence of Exercise Training

At menopausal transition, the risk of cardiovascular diseases increases. This is partly due to aging, but largely also the loss of estrogen, which has many positive effects on the circulation and protects against cardiovascular diseases. It has been suggested that the loss of estrogen may have a negative impact on the otherwise well-documented health promoting effects of exercise training, and that the time after menopause may be crucial for the effect of exercise training on the vascular function, and therefore also for the risk of thrombosis. Literature regarding the effect of exercise training on the risk of thrombosis is limited, and especially in women.

The purpose of the present study is to investigate whether the same effects of exercise training in relation to thrombosis is achieved if the exercise is initiated early compared to late after menopause. The aim is to provide knowledge-based recommendations regarding exercise. Teams sports will be used as the training intervention, because team sports benefits physical health and also includes a social element.

Part of the novelty of this project is to link functional measurements of cardiovascular health at whole body level to cell studies. Cells will be isolated from muscle samples obtained from the post-menopausal women before and after the training intervention. This will enhance the understanding of the changes that occur after prolonged loss of estrogen on thrombotic risk and vascular function, and whether exercise training can alter these parameters.
