Get a lit­tle wet and go a lit­tle faster

A spritz of wa­ter midrun could do more than just cool you down

Runner's World (UK) - - In This Issue -

ON A HOT DAY you might be more in­clined to pour wa­ter down your throat than over your head, but new re­search1 sug­gests that a head soak is far from be­ing a waste of wa­ter. In the study, a group of run­ners en­dured 33C heat while they ran 5K time tri­als. Com­pared with no cool­ing, in­ter­mit­tent fa­cial spray­ing with cold wa­ter low­ered their fore­head tem­per­a­ture and ‘ther­mal sen­sa­tion’ (how hot they felt). Not in it­self a huge sur­prise, but, in­trigu­ingly, it also in­creased mus­cle ac­ti­va­tion, lead­ing to a mod­est but still sig­nif­i­cant av­er­age 2.4 per cent re­duc­tion in 5K times. Def­i­nitely a strat­egy to try next time things are hot­ting up midrace. Just make sure you don’t do it with your sports drink…

DON’T LOSE YOUR COOL A splash of cool wa­ter can lower your tem­per­a­ture and help you pick up the pace.
