Figure 2From: Free Mg2+ concentration in the calf muscle of glycogen phosphorylase and phosphofructokinase deficiency patients assessed in different metabolic conditions by 31P MRS[Mg2+] and pH patterns during exercise and recovery. Patterns of cytosolic free magnesium concentration and pH at rest, during exercise and recovery in patients compared with typical patterns from a healthy volunteer with comparable PCr depletion. (A): pattern of [Mg2+] during exercise; (C): pattern of [Mg2+] during recovery; (B): pH pattern during exercise; (D): pH pattern during recovery.Back to article page
