Published in Muscle Nerve, Vol. 74 (5), pp. 1375-1386
Methodology
Systematic review and meta-analysis (PROSPERO registered) of longitudinal studies that followed athletes for exercise-associated muscle cramps; 9 studies, 11,274 participants, 36 meta-analyses of candidate risk factors.
Key Findings
A previous history of cramps carried about 4.4-fold higher odds of cramping. Crampers had higher, not lower, post-race potassium and magnesium. No consistent associations were found in the hydration domain.
Conclusions
Cramps track individual history more than hydration or electrolyte status.
Limitations
Mostly limited or very limited certainty; observational studies of race events; does not test supplementation.
Supplements Studied
The uncertainties regarding hydration status, electrolyte balance
magnesium (limited evidence) concentrations were also observed in individuals with EAMC
