Document Summary
Possible negative effects on performance and endurance (hard to document) Small increase in core body temperature during exercise (to keep water in) Decrease in blood volume, cardiac output, blood pressure (also less o2 in muscles) Increased body temperature (40-41 c ): chance of overheating. Heat cramps ,heat syncope, heat exhaustion, heatstroke etc. *losing water=losing weight (sweating more to lose water/weight) Short term / extreme cases of dehydration (deaths)-decreased blood flow. 21 lbs in 10 weeks (8 in the last 3 days) Loss of strength (not only dependant on hydration only but also muscle strength) Require adequate delivery of oxygen to and removal of metabolic by product from the active muscle. Change in atp cp stores/ change in acid-base balance. High-intensity muscular endurance (30 120 secs) by approximately 10% After 60 mins, water has decreased blood/plasma glucose concentration. Glucose & fructose maintains level of blood/plasma glucose concentration. Start exercise in a euhydrated (normal water content) state.
