A tennis shop sells five different brands of rackets, each of which comes in either a midsize version or an oversize version. Consider the chance experiment in which brand and size are noted for the next racket purchased. One possible outcome is Head midsize, and another is Prince oversize. Possible outcomes correspond to cells in the following table: a. Let A denote the event that an oversize racket is purchased. List the outcomes in A. b. Let B denote the event that the name of the brand purchased begins with a W. List the outcomes in B. c. List the outcomes in the event not B. d. Head, Prince, and Wilson are U.S. companies. Let C denote the event that the racket purchased is made by aU.S. company. List the outcomes in the event B or C.e. List outcomes in B and C.f. Display the possible outcomes on a tree diagram, witha first-generation branch for each brand.

Continuous Set (drop set) dropping weight until you cannot do the exercise anymore Connective Tissue Epimycium connective tissue that surrounds the entire muscle Perimycium surrounds each fasciculi Endomycium surrounds each individual muscle fiber Sarcomere smallest contractile unit of the muscle o Contractile Proteins Actin (thin filament) and Myosin (thick filament) ATP (adenosine triphosphate) kicks off the last P group and uses that energy for muscle contraction, this leaves us with ADP + Pi + energy ATPPC system (phosphagen) ADP+PC yields ATP o Anaerobic system does not need oxygen o 315 seconds of production glycolytic anaerobic does not require oxygen o carbs 23 minutes of production o lactic acid is byproduct through fermentation Oxidative system aerobic requires oxygen o Carbs + fats, unlimited production Carbs 4 cal/g (carbs are more efficient because you break them down without oxygen) Fats 9 cal/g (less efficient because it requires oxygen) Motor Unit 1 motor neuron and all the muscle fibers it controls Allornone Principle if the signal coming down the motor neuron is strong enough to reach the threshold then all the muscle fibers will contract maximally Slow Twitch fibers have very high Oxidative capacity, low motor unit force Fast Twitch fibers have very high glycolytic capacity, high motor unit force o Genetics, Training, and Age play roles in fast twitch vs. slow twitch o We recruit slow twitch first, recruit motor units synchronously o 3 Factors: Age, Training, and Genetics Increase Strength with Training Hypertrophy (fact) Recruitment of motor units to act synchronously (neural) Decrease Autogenic inhibition (neural) Nutrition 6 sources for our bodies to function 1. Carbs 4cal/g most efficient energy source a. Simple Sugars, b. Complex c. Blood glucose up, insulin up, blood glucose down 2. Fats 9cal/g most concentrated energy source a. Unsaturated b. Saturated 3. Proteins 4cal/g last resort energy source (AMINO ACIDS) a. Essential b. Nonessential 4. Vitamins a. Fat soluble ADEK b. Water soluble BC 5. Minerals mostly need them in small amounts 6. Water Caloric Intake vs. Caloric expenditure Intake diet Expenditure exercise (cardio), BMR (basal metabolic rate) (weight training), physical activity Steroids used to increase muscle mass Anabolic o Anabolism building up of tissue o Catabolismtearing down of tissue 4 factors o type o dosage o individuality o duration of use Side Effects o Increase cholesterol o Potential to increase risk for heart disease o Depression o Aggression o Acne o Increase triglycerides o Liver dysfunction o Increase risk of cancer o Increase risk of osteoporosis Men vs. Women o Men: Shrinkage of testes (not penis) Decreased sperm count Gynocomastia (BITCH TITS) Increased sex drive Increased erectile dysfunction o Women: Manlike voice Increased facial hair Hair loss Disruption in menstrual cycle or ovarian function Hypertrophy of the clitoris o Hormonally males drift towards females, vice versa o Withdrawal symptoms suicidal thoughts, depression 2 Types of Muscle Soreness 1. Acute immediately after workout, goes away generally 812 hours 2. DOMS (Delayed Onset Muscle Soreness) happens 1224 hours after workout a. Result of microscopic damage to muscle fibers involved in the exercise b. Lactic acid not a factor in this c. Severity of soreness depends on the types of forces placed on the muscle d. More likely to get sore going down stairs then upstairs e. Swelling of joints, stiffness joints, tenderness to touch, breakdown muscle f. Recovery is very important because you wont do your best while your sore g. Better to stretch after, rather than before working out
