LAST LECTURE WE TALKED ABOUT DIETARY MINERALS IN SPORTS TODAY WE WILL TALK ABOUT WATER
Lecture 15 WATER
OUTLINE OF LECTURE 15 WATER-SOME GENERAL COMMENTS
OUTLINE OF LECTURE 15 WATER-IDATME WATER-FUNCTIONS WATER-SOURCES -DEFICIENCIES AND TOXICITIES -WATER BALANCE -INTERACTION WITH OTHER NUTRIENTS AND IONS
WATER- GENERAL COMMENTS CONTINUED Essential-we can make it but not nearly in sufficient quantities
WATER-IDATME INGESTION- oral, tube, intravenous DIGESTION – not broken down ABSORPTION-passive large and small intestine TRANSPORT-free
WATER-IDATME METABOLISM- already in correct form water in = water out -we can make water-Kreb’s -synthesis -we can consume water-catabolism EXCRETION- sweat, urine, faeces, lungs
Water functions/sources/deficiencies/toxicities
FUNCTIONS OF WATER -carries nutrients and wasteproducts -fluid and electrolyte balance -ion balance -maintains the structure of large molecules e.g. proteins and glycogen -participates in chemical reactions -serves as solvent for nutrients -temperature-regulation -blood volume-regulation
-fluid and electrolyte balance -fluid balance in cells critical or cells burst -water dissolves compounds into water creating ions -ions are charged particles eg Na+ andCl- -must have equal number of charges in pool eg Na+ and Cl- i.e. that cations must balance the anions in terms of charge so that the net charge is zero -or get electrolyte imbalance
-fluid and electrolyte imbalance -sweating -diarrhea -vomiting all cause imbalance- fixed by food and drink
-acid base balance (pH) ion balance regarding carbon dioxide buffers-bicarbonate and carbonic acid lungs-carbon dioxide kidneys-bicarbonate
-maintains the structure of large molecules e.g. proteins and glycogen
-participates in chemical reactions -splitting- catabolism -elimination-anabolism -electron transport chain -elimination and electron transport chain-metabolic water
-participates in chemical reactions -splitting diag
-participates in chemical reactions Krebs- diagram
WATER BALANCE water balance required for all this above
WATER- TO MEET FUNCTIONS AND WATER BALANCE Sources-foods, drinks, water
WATER TOXICITIES AND DEFICIENCIES water balance is water in=water out i.e. IDATME note water in-consumption and metabolic water we make water out- urine, faeces, sweat, lungs, vomiting and diarrhea water balance required to avoid deficiencies and toxicities
WATER TOXICITIES AND DEFICIENCIES Deficiency-loss of function Toxicity-metabolic interference
WATER TOXICITIES AND DEFICIENCIES Deficiency-loss of function-elaboration -electrolyte imbalance
WATER TOXICITIES AND DEFICIENCIES Toxicity-metabolic interference -congestive heart failure -blood pressure -renal damage-further fluid imbalance -electrolyte imbalance -cells bursting
WATER TOXICITIES AND DEFICIENCIES Not likely if one is following an appropriate diet at all times Proper diet ensures sufficient water Water and the macronutrients they interact with frequently come in a package
THUS THERE IS AN INTEGRATION OF SOURCE, FUNCTION, DEFICIENCY AND TOXICITY
INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS CARBOHYDRATES LIPIDS PROTEINS VITAMINSMINERALS OXYGEN IONS
INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS CARBOHYDRATES -shape-function -interaction with other nutrients in solution -solvent including water soluble fibre -idatme -wwfq
INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS LIPIDS -interaction with other nutrients in solution -idatme -wwfq
INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS PROTEINS -shape-function -interaction with other nutrients in solution -idatme -wwfq
INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS VITAMINS -solvent-water soluble vitamins -interaction with other nutrients in solution -idatme -wwfq
INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS MINERALS -solvent -interaction with other nutrients in solution -idatme -wwfq
INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS OXYGEN -solvent -idatme -wwq
INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS IONS -solvent -idatme -wwfq- form including minerals -pH
