1 A nine year study of the effects of drugs on high level athletic performance

2 John Underwood has conducted nearly 14,000 physiological tests over the past 20 years on elite athletes. The following slides reflect his efforts to deter drug use by athletes.

3 We lose more people to fatal accidents during this time than during all other ages.


5 Athletes remain one of the highest "at risk" groups for drug use and abuse.

11 Pot use is increasing in many populations. Athletes are using pot at alarming levels.

12 Today’s Pot Marijuana THC content 1960-70’s 1-4% THC Marijuana THC content today 40+% THC

13 Detection Times Marijuana/Cannabinoids (THC, Marijuana) Detection Time: 1 time use only 5-8 days 2-4x per month 11-18 days 2-4x per week 23-35 days 5-6x per week 33-48 days Daily 49-63 days Most State Drug Courts have used 30 days as the cleanout rate for Cannabinoids /THC

14 Think about what you are doing off the field… That will ruin what you do on the field… American Athletic Institute Underwood


16 Don’t mess with it.

17 Master Control The human brain is made up about 100,000,000,000 information processing cells, called neurons. The neurons are connected by 'wires' that carry electrical signals, rather like the wires in a computer do. The total length of these 'wires' in a human brain is about 100,000 miles! That's half the distance between the earth and the moon.



20 The morning after heavy drinking, the body sends a desperate message to replenish its water supply -- usually manifested in the form of an extremely dry mouth. Headaches result from dehydration because the body's organs try to make up for their own water loss by stealing water from the brain, causing the brain to decrease in size and pull on the membranes that connect the brain to the skull, resulting in pain.

22 Blood flow in brain No sleep



25 A Stanford University study may help persuade at least student athletes to make more time for sleep. Cheri Mah, a researcher at Stanford, worked with basketball players, who all ran faster and made more shots over a period in which they slept at least 10 hours a night. "Athletes who get an extra amount of sleep are more likely to improve their performance in a game," says Mah, who released results from an ongoing study in June. "It's not common knowledge, because if people understood how much of a difference (getting more sleep) could make athletically," they'd incorporate it more into their lives and not focus solely on nutrition and exercise.

26 The CNS can only be at maximal intensive level for physical activity and function for 2-3 hours during a 24 hour period Over stimulation of the Central Nervous System eventually results in chronic fatigue and breakdown. ENERGY DRINKS ACTUALLY LIMIT THE ABILITY TO MAINTAIN HIGH LEVEL MENTAL OR PHYSICAL PERFORMANCE RATHER THAN INCREASE IT.

55 ENDURANCE REDUCED American Athletic Institute Oxygen consumption was reduced by 4.9 ml/kg/min…



58 Hypoglycemia is defined as a blood sugar < 50 mg/dl the body has trouble making more glucose because it is expending its energy metabolizing the alcohol. Both of these effects of alcohol can cause severe hypoglycemia 6 to 36 hours after a heavy drinking episode.


60 LOST PERFORMANCE POTENTIAL The residual effect of alcohol or a hangover has been shown to reduce performance by an average of 11.4% in elite athlete populations.

61 LOST PERFORMANCE POTENTIAL American Athletic Institute Elite level athletes lost an average of 11.4% from their median performance level as a result of the residual effect of alcohol…

62 Alcohol suppresses testosterone production in all humans.


64 Some teen males who drink heavily & regularly have testosterone levels similar to female levels.

65 American Athletic Institute has studied the impact of alcohol on condition in elite athletes. Impact has shown significant projections in lost physiological condition that correlates to as much as 14 days of lost training effect…for each time drunk… AMERICAN ATHLETIC INSTITUTE 2005
