  2. LAST LECTURE WE TALKED ABOUT DIETARY MINERALS IN SPORTS TODAY WE WILL TALK ABOUT WATER

  3. Lecture 15 WATER

  4. OUTLINE OF LECTURE 15 WATER-SOME GENERAL COMMENTS

  5. OUTLINE OF LECTURE 15 WATER-IDATME WATER-FUNCTIONS WATER-SOURCES -DEFICIENCIES AND TOXICITIES -WATER BALANCE -INTERACTION WITH OTHER NUTRIENTS AND IONS

  6. WATER-SOME GENERAL COMMENTS H2O 

  7. WATER- GENERAL COMMENTS CONTINUED Essential-we can make it but not nearly in sufficient quantities

  8. WATER-IDATME INGESTION- oral, tube, intravenous DIGESTION – not broken down ABSORPTION-passive large and small intestine TRANSPORT-free

  9. 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

  10. Water functions/sources/deficiencies/toxicities

  11. 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

  12. -carries nutrients and wasteproducts

  13. -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

  14. Fig. 12-4, p. 390

  15. -fluid and electrolyte imbalance -sweating -diarrhea -vomiting all cause imbalance- fixed by food and drink

  16. Fig. 12-6, p. 391

  17. -acid base balance (pH) ion balance regarding carbon dioxide buffers-bicarbonate and carbonic acid lungs-carbon dioxide kidneys-bicarbonate

  18. Fig. 12-8, p. 393

  19. Fig. 12-7, p. 392

  20. -maintains the structure of large molecules e.g. proteins and glycogen

  21. -participates in chemical reactions -splitting- catabolism -elimination-anabolism -electron transport chain -elimination and electron transport chain-metabolic water

  22. -participates in chemical reactions -splitting diag

  23. Fig. 6-3, p. 175

  24. -participates in chemical reactions Krebs- diagram

  25. -serves as solvent for nutrients

  26. -temperature-regulation

  27. -blood volume-regulation

  28. WATER BALANCE water balance required for all this above

  29. Table 12-3, p. 385

  30. WATER- TO MEET FUNCTIONS AND WATER BALANCE Sources-foods, drinks, water

  31. Table 12-2, p. 385

  32. 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

  33. WATER TOXICITIES AND DEFICIENCIES Deficiency-loss of function Toxicity-metabolic interference

  34. WATER TOXICITIES AND DEFICIENCIES Deficiency-loss of function-elaboration -electrolyte imbalance

  35. Table 12-1, p. 384

  36. WATER TOXICITIES AND DEFICIENCIES Toxicity-metabolic interference -congestive heart failure -blood pressure -renal damage-further fluid imbalance -electrolyte imbalance -cells bursting

  37. 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

  38. THUS THERE IS AN INTEGRATION OF SOURCE, FUNCTION, DEFICIENCY AND TOXICITY

  39. INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS CARBOHYDRATES LIPIDS PROTEINS VITAMINSMINERALS OXYGEN IONS

  40. INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS CARBOHYDRATES -shape-function -interaction with other nutrients in solution -solvent including water soluble fibre -idatme -wwfq

  41. INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS LIPIDS -interaction with other nutrients in solution -idatme -wwfq

  42. INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS PROTEINS -shape-function -interaction with other nutrients in solution -idatme -wwfq

  43. INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS VITAMINS -solvent-water soluble vitamins -interaction with other nutrients in solution -idatme -wwfq

  44. INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS MINERALS -solvent -interaction with other nutrients in solution -idatme -wwfq

  45. INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS OXYGEN -solvent -idatme -wwq

  46. INTEGRATION OF WATER WITH OTHER NUTRIENTS AND IONS IONS -solvent -idatme -wwfq- form including minerals -pH

  48. Fig. 12-8, p. 393

  49. OUTLINE OF LECTURE 15 WATER-SOME GENERAL COMMENTS

  50. OUTLINE OF LECTURE 15 WATER-IDATME WATER-FUNCTIONS WATER-SOURCES -DEFICIENCIES AND TOXICITIES -WATER BALANCE -INTERACTION WITH OTHER NUTRIENTS AND IONS
