Abstract: Aging is associated with a variety of changes in the neuromuscular system, which could theoretically reduce maximal voluntary force production.In women, menopause further enhances the loss of muscle mass and strength.These are mainly due to declining estrogen hormone concentrations.Estrogen is capable of affecting muscle function both through the central nervous system or directly through the muscle tissue.The interpolated twitch technique is a common method in the investigation of the ability to activate muscle.Transcranial magnetic stimulation (TMS) on the other hand can be used to study the inhibition-excitation phenomenon in the human brain through a non-invasive procedure.From a research perspective the quantitative assessment of muscle activation is essential in the evaluation of human muscle function.The aim of this thesis was to study the effects of the stage of menopause on the ability to activate the muscles of the lower extremity during isometric plantarand dorsiflexion tasks.Electrical nerve stimulation was performed for a maximal ACSM American College of Sports Medicine AD Analog-to-digital
