EIMS and Impedance Changes in the Biceps Brachii

The purpose of this study is to examine the changes in muscle size following exercise due to swelling. We will try to evaluate this by using a device that sends and receives an electrical current through the tissues of the body with a process called electrical impedance myography or EIM. Previous research utilizing EIM or similar processes suggests that the short-term increases in muscle size after lifting weights is partly caused by an increase in water within the cells.

We are also interested in determining whether muscle swelling associated with exercise using ultrasound is reflected in electrical current changes and passive tissue properties such as muscle stiffness and tone, measured with myotonography (Myoton ®) during the duration of exercise.

This is a 2 visit study that will last 75-120 minutes. Participants will complete a bicep curl protocol that will induce a “muscle pump”.
