Does three percent hypohydration affect threshold frequency of electrically induced cramps?
Mild hypohydration with minimal neuromuscular fatigue does not seem to predispose individuals to cramping. Thus, cramps may be more associated with neuromuscular fatigue than dehydration/electrolyte losses. Health care professionals may have more success preventing exercise-associated muscle cramp by focusing on strategies that minimize neuromuscular fatigue rather than dehydration. However, the effect of greater fluid losses on cramp threshold frequency is unknown and merits further research.
Our results suggest that the baseline peripheral endothelial function could predict the long-term outcome of CRT. The results also suggest that improvement of coronary microcirculation might be associated with the better baseline endothelial function.
