  1. Sports Supplements Food supplements V Natural Foods? CREATINE - Provides energy for rapid muscular contractions/maximal work over short period of time Produced/formed by the body – energy source for ATP resynthesis Additional supplement said to raise body’s level of creatine Advantages Disadvantages Some benefit to high intensity/ Increases body mass Short bursts Poss long term effect on Increases amount of creatine in kidneys Body Muscle cramping Not a banned substance yet Diarrhoea

  2. Protein (Protein shakes) • Advantages: Disadvantages: Builds greater muscle mass Excess protein dealt Amino Acids – used in energy system with by liver/kidney - may have long term eff NO conclusive evidence to improve muscular strength/power or endurance Herbal Remedies Medicinal – using plant extracts Quantities so small - Anrica – reduces muscle soreness/swelling little/no effect within body Psychological….?

  3. Caffine– Stimulant • Advantages: Disadvantages: • Extended aerobic exercise Anxiety, stomach upset • Increase use of lipids (fats) to HR abnormalities • Provide energy for ATP resynthesis – Diuretic – unnecessary Saves glycogen store pre-exercise loss of fluid • Limited evidence of increasing Can directly affect temp regulation • Neuromuscular function – favourable Impact on D.M / R.T

  4. Bicarbonate of Soda • White soluble compound (NaHCO3) used in evervescent drinks and as an antacid. • “Soda loading” to delay the onset of fatigue during prolonged anaerobic exercise. • Body has a “buffering system”. The ability of the blood to compensate for additions of lactic acid/hydrogen ions and maintain pH level. • Blood increases in acidity, caused by the diffusing of lactate and Hions from the muscle cells • Naturally occurring bicarbonate makes up part of the buffering system • Increasing amount of bicarbonate in the system = delays fatigue during anaerobic exercise

  5. Increased amounts of bicarbonate, will allow H ions to leave the muscle cells at a faster rate – allowing anaerobic energy systems to be used for longer. • Benefits: • Soda loading can be of benefit during near maximum intensity – for 1-7 mins, or sports where repeated anaerobic bursts are required. • Can also help high intensity aerobic exercise but NOT LOW INTENSITY • 5 equal doses should be taken at 30 min intervals starting 3 hrs before competitIon • Stomach cramps/diarrhoea only known side effects
