Calcium Pump

Exercise associated muscle cramps are affected by calcium. Could this be as a result of low sugar? So could all these things somehow tie together? And you ask, how how does calcium relate to glycogen, blood glue, cos carbohydrate? We actually need sugar not only to contract the muscle, but also to help it relax.

Episode notes

What role does glycogen availability play in cramping and what is the latest research showing us about why cramps happen? Orange Seal Off-Road Team’s Alex Wild will join us to dig into this as well as discussing fitness plateaus, endurance athlete guidelines for protein intake and more. Join us live for Episode 340 of the Ask a Cycling Coach Podcast!
