Section 1

Question Answer
What % of BW does dehydration affect aerobic exercise performance?>2%
What causes pre-existing hypohydration?beginning exercise hypohydrated caused by inadequate rehydration, often in athletes who have to "make weight" or those that train twice or more a day
What causes exercise induced hypohydration?loss of sweat through exercise, prolonged exercise and prevalent in hot/humid environments

Section 2

Question Answer
5km treadmill performance, hypo vs euhydration6% impairment on average in 5km performance when hypo (Fleming and James 2014)
Fluid restriction effects on run to exhaustion25% reduction in exercise capacity
Environment temperature 10,20,30 or 40 degrees, 0 or 4% dehydrated athletesgreater temperature exacerbates the negative effects of hypohydration
24h fluid restriction with maximal strength test before and after voluntary force production max reduced with hypohydration
0,2.5,5% hypohydration, back squat resistance exerciseimpaired by hypohydration (resistance exercise) - as hypo increases, performance decreased in all groups
skill performance (shuttle run and bowling) 1h exercise with/without fluid replacementimpaired line and length of bowling but not shuttle run performance
skills - basketball. 3h exercise, rest period then 80 min ball game. no rehydrationimpaired shots on the move but not accuracy from foul line

Section 3

Question Answer
race data, hypohydrationhypohydration increased race speed
hypohydration familiarisation; overview (alternative)unfamilar hypohydration impairs exercise performance, familiarisation attenuates this impairment.
endurance training may do what for athletes?repeatedly familiarise them with hypohydration
hypohydration is theoretically ergogenic during running - why?reduces weight to be carried
can we detrmine the level at which hypohydration impairs endurance athletes?no, more work needed
