Water Intake After Dehydration Makes Muscles More Susceptible To Cramp But Electrolytes Reverse That Effect, Wing Yin Lau, Haruyasu Kato, Kazunori Nosaka
Research outputs 2014 to 2021
Objective No previous study has compared water and oral rehydration solution (ORS) intake after dehydration induced by exercise in the heat for the effect on muscle cramps. The present study tested the hypothesis that water ingestion after dehydration would increase muscle cramp susceptibility, but this would be prevented by ORS ingestion. Methods Ten men performed two bouts of downhill running (DHR; -5%) in the heat (35°C-36 °C) until their body mass was reduced by 2%. Ten minutes after DHR, either spring water or electrolyte water similar to ORS (OS-1 ®) was ingested in a counter-balanced order on two different days …
