Section 1

Question Answer
Fleming & James 2014: details repeated familiarisation to hypohydration on hypohydrated ex performance
Fleming & James 2014: method EU and HYPO trial = 45 min run and 5km TT. 4 habituation sessions: replication of HYPO (but 60 min run and no TT). then replicated EU and HYPO trials
Fleming & James 2014: resultsHypohydration decreases 5km running performance (6% impairment meaningful) in subjects unfamiliar with hypohydration protocol. 4 habituation/familiarisation sessions w/hypo protocol attenuated the performance decrement, via attenuation of RPE during hypo ex

Section 2

Question Answer
Fallowfield 1996: details effect of water ingestion on endurance capacity during submax treadmill running
Fallowfield 1996: method2 treadmill 70% VO2 max runs to exhaustion: 1) no fluid ingested 2) water before and throughout exercise
Fallowfield 1996: results25% decrease in exercise capacity w/fluid restriction

Section 3

Question Answer
Kenefick 1985/2010: detailshypohydration on aerobic performance in compensable conditions of 10,20,30 and 40
Kenefick 1985/2010: method4 groups in diff temps, in hypo (4%BM) and eu states. 30 min preload ex (50% VO2max on cycle ERG) then 15 min self-paced TT cycle erg
Kenefick 1985/2010: resultshypohydration degrades aerobic performance to a greater extent with increasing heat stress. T>29degrees, 4% HYPO degrades performance 1.6% for each additional 1 degrees. CV strain from high skin blood flow and blood vol decrease induced by HYPO, important contributor to decreased performance

Section 4

Question Answer
Minshull & James 2013: details hypohydration and fatigue on neuromuscular activation performance
Minshull & James 2013: method24h EU and HYPO. strength tests (ie leg extension) performed before and after hydration status
Minshull & James 2013: resultsmax voluntary force production reduced with hypohydration. n.d. on fatigue performance of knee extensors.

Section 5

Question Answer
Baker 2007: details 1,2,3,&4% dehydration vs EU on basketball performance in adult male players.
Baker 2007: method3h interval treadmill walking with/without fluid replacement. 6 trials in random order 1. carb electrolyte solution. 2. EU control. 3. 1% 4. 2%. 5. 3%. 6. 4% dehydration
Baker 2007: resultsprogressive decrease in performance as dehydration from 1-4%. e.g. impaired shots on the move but not foul line shots (stationary)
