CHAPTER 16

QuestionAnswer
What are ergogenic aids? work producing
What are ergolytic aids? work breaking - not a beneficial effect; such as caffeine - - too much makes you shaky; negative effects
What are amphetamines? & what do they affect? influence heart, blood, circulation, & aerobic endurance; counteract or delay or onset sensation of fatigue; counteract central nervous system inhibition
What are b-blockers? & what do they affect? influence heart, blood, circulation, & aerobic endurance; aid in relaxation & stress reduction
What is caffeine? & what does it affect? influence heart, blood, circulation, & aerobic endurance; supply fuel for muscle and general muscle function; counteract or delay or onset sensation of fatigue;
What are diuretics? & what do they affect? influence heart, blood, circulation, & aerobic endurance; result in weight loss or weight gain
What are anabolic steroids? & what do they affect? acts on muscle mass & strength; result in weight loss or weight gain
What is human growth hormone? & what does it affect? supply fuel for muscle & general muscle function; acts on muscle mass & strength; result in weight loss or weight gain
What are sympathomimetic amines? Amphetamines (ephedrine, pseudoephredrine); the benefits are weight loss, better concentration & focus, more competitiveness, enhanced performance
How do sympathomimetics work? They increase dopamine & norepinephrine, making the brain more active
What are the risk of amphetamines, ephendrine? cardiovascular stress & disease, heat stroke (because it acts like a diuretic, shuts off hypothalamus & POAH), addiction,
What is the risk of heat stroke with amphetamines? High performance leads to immediate heat stroke & sometimes immediate death - you bypass all the signs & symptoms of heat cramps
What are B-blockers? Reduce sympathetic effects - depressants; used for high blood pressure - - reduce heart rate
How does a B-blocker work? Blocks stress signals; vasodilation of blood vessels
Risk of a B-Blocker? Asthmatic person should not take b-blocker; cardiac failure because of low blood pressure; fatigue & impaired performance
What does caffeine do? alertness, feel more competitive; more energy reduces fatigue; enhanced mobilization of free fatty acids; glycogen sparing
What are caffeine's effects? Blocks adenosine receptors - - blocking the fatigue mechanism. IT blocks a depressant so that you don't feel fatigued.
What do diuretics do? Help drop weight fast if in need of it (wrestling); it can also dilute other banned substances in urine samples; increase urine output by inhibiting sodium & water reabsorption
What risk do diuretics have? Put you at more risk for heat illness
What do recreational drugs do? alcohol - mood enhancer wether good or bad; cocaine - like amphetamine; marijuana - parasympathetic effector; nicotine - depressor & stimulant
What are anabolic steroids used for? They are androgenic; they enhance anabolic function (so build bone & muscle)
What are the proposed benefits for anabolic steroids? reduced fat mass; facilitate recovery faster after exercise; increased fat-free mass & strength. -- trying to gain muscle mass; more protein synthesis; anti-catabolic effects because they inhibit cortisol
Anablic steroid risks with men? early growth stoppage due to the growth plates closing; suppression of normal hormones (cells become insensitive to testosterone or growth hormone) & excess estrogen.
Anablic steroid risks with women? disrupted menstruation/ovulation, development of masculine characteristics
General anabolic steroid risks? cancer risks; cardiovascular risks (cardiac hypertrophy, heart attack, cardiomyopathy); emotional risks (aggression & violence increase); increased incidence of birth defects
What are the benefits of human growth hormone? stimulates protein & bone growth; increased free fatty acid mobilization & decreased fat mass
What are the risks of too much human growth hormone? diabetes; acromegaly (keep growing but lifespan is short)
what are physiological agents? what your body normally produces
What is blood doping? drawing your blood out, spin it, freeze it & reinject it later after 5-6 weeks ago. so now you have more red blood cells - better oxygen carrying capacity
How to test blood doping? hematocrit. there is a level that you need to be at, if you are higher than you are out.
What is bicarbonate loading & why would you do it? increase in all out performance for 1-7 minutes
