    (this multiple choice question has been scrambled)
  6. What are the three recommended times of the year to test a sports team?
    End of pre-season, end of season, end of post-season
  7. Name 3 careers in the field of exercise science and give a short description of what they do and what background you need in terms of education and certification.
    • Physical Therapist: a therapist that helps get people back on their feet if they have been injured or have had to have surgery. They work on strengthening muscles which can sometimes be painful but it is very beneficial for the patient in order to get back to health. Most physical therapists now are required to obtain a doctorate degree.
    • Strength and Conditioning Coach: works for sports teams at the high school, collegiate and professional level. Main job is to strengthen and condition athletes using specificity according to what sport they coach. Most strength and conditioning coaches must be certified through NCSSA and have at least a bachelor's degree.
    • Personal Trainer: designs workout plans for different individuals based on goals and
    • needs. They must also have a great understanding of how to do specific
    • exercises correct so their clients are not injured. A degree is not
    • required but can be obtained; many become personal trainers through
    • certification.
  8. Name the three energy systems.
    Phosphagen, Glycolytic, Oxidative
  9. During the first several seconds of Tug-o-war, which energy system provides the bulk of the energy?
    Phosphagen
  10. During the last few miles of a mini-marathon, which energy system is providing the majority of the energy?
    Oxidative
  11. What very popular supplement helps improve the phosphagen system? How does it do so?
    Creatine, it improves the phosphagen system by adding more phosphates to the blood for ATP production
  12. Lactic acid causes a burning sensation and will cause an exerciser to stop; it is mainly the result of which energy system?
    Glycolytic
  13. Write the predominant energy system for each activity.
    Marathon: _________ Football _________ Wrestling _________
    Pole Vault _________ Tennis _________
    Write the predominant energy system for each activity.

    Marathon Oxidative Football Phosphagen Wrestling Glycolytic

    Pole Vault Phosphagen Tennis Phosphagen
  14. All three energy systems rely heavily on oxygen. (True/False)
    False
  15. After 15 or so seconds of Tug-Of-War, which energy system takes over?
    Glycolytic
  16. List 3 physiological reasons why one's cardiovascular conditioning improves with regular cardiovascular endurace training. Also, list whether they are central or peripheral components.
    • 1. The heart will get bigger: central
    • 2. Increased capillaries (mostly in legs): peripheral
    • 3. The stroke volume increases: central
  17. List 2 physiological reasons why muscular strength increases with regular resistance training. Also, list whether they are central or peripheral components.
    • 1. Muscle fibers hypertrophy and get bigger: peripheral
    • 2. The Nervous System learns to recruit muscle fibers better over time: central
  18. The Principle of ________ explains why a great sprinter may not be a great distance runner.
    Specificity
  19. What are the 4 components of the FITT principle and how can you use each of them to improve John's bench press.He is currently bench pressing 3 times per week with 6 sets of 10 reps and 100# for each set for a 15 min workout.
    • Frequency (how often)- up bench pressing to 4 times per week
    • Intensity (how hard you work)- add 5lb= 105#
    • Time (how long you workout)- add one more set to increase the time
    • Type (what exercise you are doing)- change to a decline press
  20. A sprinter has a greater percentage of _____-twitch MM fibers compared to a marathon runner. What are 3 other adjectives for that muscle fiber?
    • Fast
    • White, large, type II
  21. A marathoner has a greater percentage of ____-twitch MM fibers compared to a sprinter. What are 3 other adjectives for that MM fiber?
    • Slow
    • Red, small, type I
  22. The repetition zone for hypertrophy is:
    6-15 zone
  23. What is the importance of the "intermediate muscle fibers," why should they be considered when designing a training program for an athlete?
    Intermediate fibers can be trained either to be Type I (slow-twitch) or Type II (fast-twitch). Depending on your sport, you should take this into consideration and work on exercises specific to your sport and what type of MM fiber would be most beneficial.
  24. The training intensity (the % of 1-Rep Max) for "power" training is (greater than/less than) the training intensity for hypertrophy training.
    Greater than
  25. To increase maximal power, your repitions should be in the:
    1-5 zone
  26. When training to increase "power" the athlete will spend the majority of the time using what energy system?
    Phosphagen
  27. What historic event sparked the government's interest in physical fitness and the need for science-based exercise and fitness programs?
    World War I and II
  28. List the 4 former exercise "myths" that have been proved wrong by science.
    • 1. Athlete's heart is dangerous in cardio training because enlarged hearts aren't good.
    • 2. "No pain, No gain" was a popular motto because light workouts didn't produce results.
    • 3. People over the age of 40 cannot benefit from exercise.
    • 4. Muscles slow you down
  29. What university created the Fatique Laboratory that greatly expanded the study of exercise science in the U.S.?
    Harvard University
  30. What are the 2 primary areas of study or inquiry for exercise science?
    Health-related and sports-related

    60

    eccentric contraction
  33. What are the definitions for gross anatomy, histology, and comparitive anatomy?
    • Gross anatomy: the study of cadavers where anatomy can be seen without the use of a microscope
    • Histology: the study of muscles and tissues viewed microscopically
    • Comparative anatomy: relating the anatomy of animals to humans: For example, a birds wing to a human's arm
  34. Which of the following cardio training methods would you recommend for a football lineman?
    A. 1 mile run
    B. 3-min hill runs
    C. 400 yard sprints (1 min+)
    D. 10 sec hill sprints
    D.
    (this multiple choice question has been scrambled)
  35. Who is Milo of Crotona and what Fitness principle does his story represent?
    Milo of Crotona was an Olympian that carried a baby calf on his back until it grew up. He won the Olympics because of his principle of overload. Which states that in order to make gains, you must modify your workouts to see improvements.
  36. What type of cardio is best for fat loss: steady-state heart rate or high-intensity intervals? Why?
    High Intensity Intercals keeps your body alert and keeps it from adapting to the same steady workout. It also works your body after you workout and because of you will feel afterburn.
