Having a hydration strategy can reduce the risk of overheating during long-distance marathons, said Dr Ivan Low, Research Fellow and Exercise Physiologist at NUS Medicine’s Department of Physiology, and Dr Mok Ying Ren, Resident at the Department of Orthopaedic Surgery at the National University Hospital.
Research evidence from NUS Medicine’s Department of Physiology has shown that ingesting ice slushies before exercise can lower pre-exercise core temperature and increase heat tolerance in hot and humid conditions. Runners should never toe the starting line in an under-hydrated state. They should always ensure that the body is well (but not overly) hydrated before a race and avoid alcoholic beverages before training and races.
Dr Low and Dr Mok also recommended runners to drink more if they perspire more.
