Water 2 readings

Question 1

Flemming and James 2014

Answer 1

Does familiarisation to exercise in hyphydrated state improve hypohydrated exercise performance

manipulate intake for 24 hrs to make hypo or eu hydrated
4 habituation sessions when hypo
time trial in hypo state

faster TT performance in hypo state following familiarisation
hypo impairs performance if not used to it, decrease in performance and RPE attenuated by familiarisation

Question 2

Fallowfield et al 1996

Answer 2

Does consuming water in sub max exercise improve performance

run to exhaustion either consuming water before and during or not

consuming = greater time to exhaustion

Question 3

Kenfick et al 2010

Answer 3

does hypohydration cause more of a detrimental effect with increased heat stress

performance tested when eu and hypohydrated at 4 different temperatures

hypo degrades aerobic performance to a greater extent with increasing heat stress
thought to be due to increased skin blood flow and blood vol depletion

Question 4

Minshull and James 2013

Answer 4

Does hypohydration negatively impact on neuromuscular performance

24 hrs of eu or hypohydration
checked vol. peak force
evoked peak force
electrochemical delay
rate of force development
of knee extensors

hypo = decreased in vol peak force but not evoked
maybe alters RPE?/

Question 5

Baker et al 2007

Answer 5

does hypo cause impairment of skill based aspects of basketball performance

3 hr treadmill exercise with or without hydration
skill tests and skilled basketball drills

performance impaired in: shooting drills
time to complete skilled movement
fewer shots made
impairment occured at 2% bw loss
