Dangers of Dehydration
DEHYDRATION HAS BEEN SHOWN TO:
-Reduce blood and plasma volume, this results in a decrease in the amount of blood pumped out by the heart, consequently the heart has to work harder in an attempt to maintain an adequate blood (oxygen) supply to the working muscles. (Robergs & Roberts, 1997;Clarkson,1998)
-Decrease testosterone levels (Both et al., 1993;Viscardi, 1998)
-Impair the body’s ability to sweet, resulting is an increased risk of overheating. (Armstrong, 1992; ACSM, 1996).
-“Dehyrdation results in reduced muscle blood flow, waste removal, and heat dissipation, all of which are necessary for sustained, high power muscle action in events such as boxing and judo.” (Armstrong,1992, p.29)
-Taken to the extreme, rapid weight loss when achieved through dehydration can be fatal. Viscardi (1998) identifies that excessive dehydration can harm bodily functions, leading to kidney failure, heat stroke or heart attack, indeed in 1997, within a period of thirty-three days, three young American wrestlers tragically died whilst trying to ‘make their weight’ (Hickling, 1999).
