  • The popularity of coffee has been increased dramatically over the last decades , from jump- starting your day to an aspect of social engagement ‘
  • There are many different types of coffee , and they usually differ on factors such as taste or flavor, type of preparation, and the caffeine content of various types ‘Caffeine content can range from a couple of milligrams in one once of milk chocolate to ~ 115 mg in 12 oz of Red Bull energy drink ‘The most popular form of caffeine ingestion is via coffee , and the content typically depend on method and duration of brewing 1.

    17. 17. Exercise, It is any Bodily Activity that Enhances or Maintains Physical Fitness and Health. [2] wikipedia
    18. 18. Types of Exercise, •Anaerobic Exercises, •Aerobic Exercises. [3] 3 - Sports Nutrition ; A Practical Manual for Professionals, Marie Dunford, 2006
    19. 19. Anaerobic System, Glycolysis system OR Lactate system, Allow for Continued production of ATP for 60-180 sec, when adequate O2 is not enough for aerobic exercise, Can Only use GLUCOSE for fuel. [3] 3 - Sports Nutrition ; A Practical Manual for Professionals, Marie Dunford, 2006
    20. 20. Lactate
    21. 21. Lactate, Lactate is released into blood and rapidly metabolized by the high oxidative cells as heart and skeletal muscles, Lactate production increase as the intensity increase, Lactate entry = lactate clearance by the liver, there is no problem, Entry > clearance, accumulation in blood, more acidity in muscle cells, inhibition of FA breakdown, fatigue and decreased performance. [3] 3 - Sports Nutrition ; A Practical Manual for Professionals, Marie Dunford, 2006
    22. 22. Lactate Threshold, Term used to describe Exercising beyond the and exercise level at threshold results in which an imbalance increase blood lactate occurs between lactate levels and more reliance production and on CHO for fuel via clearance, anaerobic glycolysis. [3] 3 - Sports Nutrition ; A Practical Manual for Professionals, Marie Dunford, 2006

    24. 24. Aerobic System, Requires O2, Performed at Moderate Levels of Intensity for Extended Periods of Time, Such as: Cycling, Swimming, Walking, Running, or Playing Tennis. [4] wikipedia
    25. 25. Cont, Aerobic system is more efficient in ATP production than Anaerobic BUT Aerobic system is slower at ATP rate than Anaerobic. 3 - Sports Nutrition ; A Practical Manual for Professionals, Marie Dunford, 2006

    35. 35. Effect of Caffeine Consumption from Coffee on Exercise Performance, Caffeine ingestion before Mechanism, exercise to prolonged it & delays fatigue , However , the mechanism of that are unclear, There is study mentioned the BUT caffeine is elevated plasma epinephrine which help muscles to contract. [7] 7- Van Soeren MH, Can J Appl Physiol, 1994
    36. 36. Effect of Caffeine Consumption from Coffee on Exercise Performance, Increase Muscle Caffeine epinephrine contraction 7- Van Soeren MH, Can J Appl Physiol, 1994
    37. 37. Effect of Caffeine Consumption from Coffee on Exercise Performance,  The demethylation of caffeine by the hepatic cytochrome p-450 oxygenaes begins within minutes and generate paraxanthine,  This compounds when appear in plasma work as adenosin receptor antagonists which contract the muscle,  As the study said the caffeine consider as very active drug that increase exercise endurance. [7] Van Soeren MH, Can J Appl Physiol, 1994
    38. 38. Effect of Caffeine Consumption from Coffee on Exercise Performance, [7] demethylation Paraxanthine Caffeine Adension receptor antagonists hepatic cytochrome p- 450 oxygenaes Muscle contraction Van Soeren MH, Can J Appl Physiol, 1994
    39. 39. Effect of Caffeine Consumption from Coffee on Exercise Performance,  The recent studies mention that mainly: Caffeine stimulate lipolysis. [8]  Which is release epinephrine and in response FA librated into blood, [3]  And when use FA as fuel for energy is stimulate muscle cells to manufacture more and larger mitochondria(that increase performance). [3] 3 - Sports Nutrition ; A Practical Manual for Professionals, Marie Dunford, 2006 8- Jane Shearer, Appl. Physiol. Nutr. Metab, 2008
    40. 40. Effect of Caffeine Consumption from Coffee on Exercise Performance,  And the heart and lungs becomes stronger and better able to deliver O2 to muscle at high activity intensities (and that increase the endurance and performance). [3]
    41. 41. Effect of Caffeine Consumption from Coffee on Exercise Performance,  One said the caffeine can prolong the endurance aerobic exercises,  And caffeine can increase the blood glucose, lactate and catecholamine levels to promote the lipolysis. [9] Ellerington K, Med Sci Sports Exerc, 2002
    42. 42. Effect of Caffeine Consumption from Coffee on Exercise Performance,  It is improvement in anaerobic exercise performance is likely as a result of stimulation of skeletal muscle by caffeine.[9]  Other mention caffeine improves psychomotor performance during exercise but not at low temperature. [10] 9-Ellerington K, Med Sci Sports Exerc, 2002 10-Hanna Kaciuba-Usciklo,psychopharmachology 2001
    43. 43. Effect of Caffeine Consumption from Coffee on Exercise Performance,  And other have suggested that caffeine has an effect on Ca2+ release via the ryanodine receptor, and this release was not result of adenosine antagonism that potentiate sub maximal skeletal muscle contractile force, thus eliciting an ergogenic effect. [1] 1 - Handbook of Nutraceuticals and Functional Foods . Edited by Robert. C. Wildman 2007 .
    44. 44. Conclusion, The most commonly used dose of caffeine is approximately 6mg/kg of body weight, and this dose has been shown to give improved endurance exercise capacity and performance. [1] 1 - Handbook of Nutraceuticals and Functional Foods . Edited by Robert. C. Wildman 2007 .
    45. 45. Conclusion,  The caffeine have only an ergogenic effect at intake as low as 1-3gmkg of body weight, cause it has a little or no effect on epinephrine and metabolites. [1] 1 - Handbook of Nutraceuticals and Functional Foods . Edited by Robert. C. Wildman 2007 .
    46. 46. Conclusion,  On the other hand, doses as high as 9mg/kg of body weight have been used, cause highest doses of caffeine result in increase in glycerol and FFA which effect on performance but it is debated wither the ergogenic effect are additive at higher doses. [1] 1 - Handbook of Nutraceuticals and Functional Foods . Edited by Robert. C. Wildman 2007 .
    47. 47. Recommendations  It is important to note that you will not gain the same benefits from the consumption of coffee as from taking a caffeine supplement. The reason for this appears to be due to another, as yet unknown substance, within coffee, that inhibits the positive effects of caffeine.
    48. 48. Recommendations  It should be noted that athletes who regularly consume large quantities of caffeine will gain less of a benefit from its consumption due to a decreased physiological response.
    49. 49. Recommendations,  Long term caffeine use should be avoided since caffeine consumption causes an increase in the levels of stress hormones, Long term exposure to high stress hormone levels will leave you feeling drained and run down.
    50. 50. Recommendations,  General recommendation to improve endurance, or power, performance would be to consume 150-200mg of caffeine 30-60 minutes prior to competition – this will not result in a positive doping .
