    2. Ergogenic aids fall into two categories: Physical cheering, music, altitude training, sauna and massage, psychology etc. Chemical and pharmacological anabolic steroids, stimulants, narcotic analgesics, beta blockers, diuretics, amino acids, vitamins etc.

    3. Ergogenic Aids: History of Use Ancient Greek Olympians ate mushrooms; As long ago as the third century BC, there were reports of Olympians taking potions of go-faster "ground-up hooves of ass boiled in oil and rose-hips" Aztec athletes ate human hearts In late 1800s, European cyclists took heroin, cocaine "speedballs," and ether-soaked sugar tabletsfirst drug-related fatality in 1886 Winner of 1904 Olympic marathon took strychnine and brandy during race Winner of 1920 Olympic 100-m dash drank sherry with raw egg before race Development and use of anabolic steroids in 1950s In 1960 Olympics, Danish cyclist died in road race from amphetamine overuse In 1967 Tour de France, famed British cyclist, Tim Simpson, also died from amphetamine overuse Olympic testing began in 1968 for stimulants Victor Conte, Jr., BALCO founder, convicted in 2004 of providing designer steroids/supplements for numerous athletes in professional football, baseball, and track and field

    4. Ergogenic Aids: History of Use Development of Dianabol East German female swimmers of 1970s-1980s Cyclists deaths (1987-1990) Chinese female swimmers (1992-1994) 1998 Tour de France John Ziegler, US team physician developed Dianabol after viewing Russian steroid use at 1956 World Championships in Moscow Picture of Yuan Yuan, a Chinese swimmer, being removed after bringing 13 packets of banned substance (somatotropin) to 1997 World ChampionshipsJohn Ziegler, US team physician developed Dianabol after viewing Russian steroid use at 1956 World Championships in Moscow Picture of Yuan Yuan, a Chinese swimmer, being removed after bringing 13 packets of banned substance (somatotropin) to 1997 World Championships

    5. 27 Chinese athletes removed from team Bulgarian and Romanian weightlifting teams expelled USATF relinquished drug testing alleged >12 positive tests not reported previous 2 years Picture of Andreea Ruducan, Romanian gymnast who won gold medal in Sydney Olympics only to be stripped of medal after testing positive for ephedrinePicture of Andreea Ruducan, Romanian gymnast who won gold medal in Sydney Olympics only to be stripped of medal after testing positive for ephedrine

    6. Desire to Win by Elite Athletes: Fear of disgrace and loss of personal income is greater than fear of harm 195 of 198 athletes would take illegal drug if assured of not being caught 50% would take illegal drug even if side effects were lethal in 5 years

    7. Ergogenic aids: placebo effect Left graph2% strength increase of 6 male trained weightlifters after 7 weeks; those who made the greatest gain would be accepted into the anabolic steroid study. Right graph10% strength increase of 6 trained weightlifters after being told they were taking Dianabol but were actually given a placebo.Left graph2% strength increase of 6 male trained weightlifters after 7 weeks; those who made the greatest gain would be accepted into the anabolic steroid study.

    8. Increasing Muscle Mass Anabolic steroids Growth hormone Protein supplements Picture of Ben Johnson, Canadian sprinter who won 100-m gold medal in Barcelona Olympics in 9.79 s in WR time, but was later disqualified for testing positive for stanazololPicture of Ben Johnson, Canadian sprinter who won 100-m gold medal in Barcelona Olympics in 9.79 s in WR time, but was later disqualified for testing positive for stanazolol

    9. Protein Supplementation Research suggests that athletes have 2-3X RDA higher protein needs Typical American athletes already consume this amount Increased carbohydrate intake likely more important to increasing muscle mass Currently, the RDA for protein is 0.8 g/kg/day. Thus, an 80 kg person would require a daily protein intake of 64 grams. The RDA does not recognize any additional protein need for individuals who participate in a regular daily exercise program. Furthermore, this value has not been updated since 1989, despite research suggesting that athletes require higher protein needs. Currently, the RDA for protein is 0.8 g/kg/day.

    10. Anabolic Steroids Male hormones have anabolic effects accelerated growth of muscle, bone, and red blood cells Anabolic steroids are synthetic relatives to testosterone high-volume training needed for beneficial effects inhibit protein breakdown

    11. Anabolic Steroids: Secondary Effects Androgenic effects males: testicular atrophy, breast development, ? sperm count, acne females: masculinization, facial & chest hair growth, deepening of voice, acne Additional effects aggressiveness, mood swings, altered glucose metabolism, thyroid, lipid profiles

    12. Commonly Used Anabolic Steroids Testosterone Stanazolol Nandrolone DHEA Androstenedione C.J. Hunter, American shot putter, who testing positive 4X during summer of 2000 for nandrolone.C.J. Hunter, American shot putter, who testing positive 4X during summer of 2000 for nandrolone.

    13. DHEA and Androstenedione: Precursors of Testosterone DHEA and androstenedione are androgenic hormones that are precursors to testosterone. Because of this, supplementation is thought to increase the bodys production of testosterone through natural means.

    14. In addition to being converted into testosterone, androstenedione is a precursor for estrogen. Studies suggest that, at least in college-aged men with normal testosterone levels, the body favors conversion of exogenous androstenedione into estrogens.

    15. Effects of DHEA and androstenedione after 12 weeks of training

    17. Increasing Energy Supply Carbohydrate availability feeding before/during competition enhancing fat use ? fat utilization Creatine PCr vital for ATP production during power/speed events

    18. Sport Nutrition: Carbohydrate

    19. Effect of Dietary CHO on Muscle Glycogen Repletion

    20. Effect of CHO feeding during prolonged exercise to exhaustion

    21. Sport Nutrition: Sport Drinks [CHO] affects fluid absorption rate in gut Gatorade 6% Exceed 7.2% Coca-Cola ~11% Sprite 10.2% cranberry juice 15% orange juice 11.8%

    22. Sport Nutrition: Carbohydrate Before exercise CHO intake top off liver glycogen stores During prolonged exercise CHO intake helps maintain blood glucose and spares liver glycogen After exercise high CHO intake increases rate of glycogen storage protein (~6 g) ingestion will stimulate protein synthesis

    23. Sport NutritionMinerals & Vitamins B vitamins used to make mitochondrial enzymes Vitamin D aids in skeletal Ca2+ absorption Vitamin K aids in ETC calcium used in contraction and skeletal system iron is essential component of hemoglobin

    24. Increasing Fat Availability High fat intake ? intramuscular fat stores, but doesnt benefit performance Caffeine ? fat availability and ? carbohydrate use? spares carbohydrate stores? Other nutritional products

    25. Creatine Supplementation Cr essential to maintain ATP at exercise onset effects of supplementation on performance no benefit to single-bout exercise diminishes fatigue during multiple-bout exercise allows for increased training volume

    26. Greenhaff has reported that following creatine supplementation, the rate of PCr resynthesis is faster than prior to supplementation. The greater PCr concentration at the start of the next bout should increase performance.

    31. Other Banned Substances Stimulants masks fatigue ephedrine, cocaine, amphetamines Painkillers narcotics Diuretics rapid weight loss masks steroid use Picture of Andreea Rudacan, Romanian gymnast who won gold medal in 2000 Olympics, but afterwards was later stripped of medal after testing positive for ephedrine.Picture of Andreea Rudacan, Romanian gymnast who won gold medal in 2000 Olympics, but afterwards was later stripped of medal after testing positive for ephedrine.

    32. Dehydration and Performance

    33. Buffering Acid Accumulation sodium bicarbonate buffers acid, improves high-intensity exercise (1-10 min) ? rate of lactic acid transport out of muscle

    34. Effect of Bicarbonate Loading

    35. Ergogenic Aids for Improving Athletic Performance Summary Use of banned substances is widespread at all levels Detecting banned substances doesnt keep up with continual modification of banned drugs Many claims of OTC substances as ergogenic aids are unfounded Future of performance enhancement will be alternation of genetic coding

    36. Design an ergogenic aid for a(n) endurance athlete speed athlete power athlete

    37. Research supports the benefits of ____ for enhancing performance of elite endurance athletes. a high-CHO diet during training consuming CHO during prolonged exercise consuming amino acids during prolonged exercise ingesting bicarbonate all of the above are beneficial only a and b are beneficial

    38. Which of the following statements is true? Breathing 100% O2 during exercise will increase the amount of O2 available to working muscle. Increasing the number of RBCs will increase the amount of O2 available to working muscle. Live high and train low is more beneficial to performance than live high and train high as training volume is greater when training low. all of the above are true only b and c are true none of the above are true

    39. Taking bicarbonate prior to competition will cause GI distress will not benefit performance for a 5-km race (15-20 min) may increase H+ transport from muscle all of the above are correct only a and c are correct
