Physiology

  1. A static contraction at a particular point in the range of motion is what type of ex?



    B) isometric
  2. An ex that occurs thoughout the ROM with the same resistance and variable speed of movement is which type of ex?



    C) isotonic
  3. An ex that occurs at a constant, preset speed in which the resistance is variable and accomodates at the force of contraction varies thoughout the range of motion is which type of ex?



    A) isokinetic
  4. This type of ex develops strength specifically to the position that the muscle contracts.



    B) isometric
  5. resistance is fixed at max load that allows completion of movement but no greater than that of the weakest jt position.



    B) isotonic
  6. allows for max tension at all points of ROM.



    B) isokinetic
  7. This ex is useful for limited jt motion due to pain, injury, or surgery:



    C) isometric
  8. this ex allows for both concentric and eccentric contractions however lacks aerobic conditioning, accommodation to fatigue or pain, and development of quickness.



    A) isotonic
  9. this type of training is safe. Strength gains occur at slow speeds while increased muscle endurance and hypertrophy occur at high speeds.



    A) isokinetic
  10. This muscle fiber type is red, slow to fatigue, are endurance type fibers, and are common in extensor muscles and active during aerobic activities:
    Slow twitch (type I)
  11. this muscle fiber type is white, fatigues rapidly, is found in sprinters, is common in flexor muscles, and is active during anaerobic ex's.:
    Fast twitch (type II)
  12. This type of ex is performed for at least 20 min and
    involves large muscle groups in rythmical movements
    aerobic ex
  13. cardiac training effects of aerobic ex:
    • -decreased resting and submax HR
    • -decreased systolic/diastolic BP @ rest and submax ex
    • -increased CO and SV
  14. Max HR=?
    220-age
  15. THR= ?
    HR max * 70%
  16. Karvonen's THR=?
    (HRmax - RHR) * % +RHR
  17. when can RPE be used?
    during submax ex
  18. aquatic ex:

    cooler temps for?
    warmer temps for?
    • -intense training
    • -rehab training
  19. what increases hydrostatic pressure on the body with aquatic ex?
    increased submersion
  20. what does decreasing the surface area do with aquatic ex?
    decreases turbulance and resistance
  21. what are the factors that affect training? (hint: FITT)
    Frequency: 3-5/per week for aerobic and strength gains

    Intensity: changing this is most effective way to improve aerobic fitness

    Time: 15-60 min increase this when intensity is limited.

    Type: based on desired effects
  22. T/F multiple short duration sessions are indicated when intensity is limited by enviro conditions?
    True
  23. BMI norms
    • Lean 18.5 - 22
    • healthy 20 - 24.9
    • Overwt >25
    • Obese >30

    • Men waist >40
    • women waist > 30
