Muscles need lytes: Your muscles and nerves require potassium to properly contract and relax. If low, they don't work as efficiently

Muscle contraction: Without getting to technical, your muscles contract on a cellular level in order for the muscle to work. In order for this muscles to contract, k+ and ca+ are required to cross the cellular membranes. To much, or to little potassium will upset this balance. Hope this helps.
