3. What ions play a role in muscle contraction relevant to Sarawat’s case?

Answer 1

• Overuse of skeletal muscle also causes cramps and spasm in case of athletes
• While running or doing strenous exercise the fluid and electrolyte balance get disturbed and also reduction in total body exchangable sodium store,causes contraction of interstitial fluid compartment around the muscles leads to misfiring of nerve impulses causes cramping.
