  1. How long does it take the body to replace Glycogen?
    Glycogen replaced within days
  2. How long does it take the body to remove lactic acid?
    Lactic acid removal within ~ 1 hour
  3. How long does it typically take a muscle to recover? To what extent?
    Force producing capacity returns to 90-95% within 3-4 minutes
  4. How does strength/training/tissue physiology attribute to the Children (pre-puberty) age group? (3)
    • I. Well supervised, sub maximal resistance with use of non ballistic, slow, controlled motions in preadolescent and adolescent children
    • II. Strength gains attributed to neural adaptation, insignificant increase in muscle mass
    • III. Injuries can include disruption of the primary and secondary growth centers of ossification
  5. How does strength/training/tissue physiology attribute to the Adolescence age group? (3)
    • I. Marked difference in gender due to hormonal changes
    • II. Muscle mass increases 5 fold in males and 3.5 fold in females
    • III. Strength increases 30% from age 10-16
  6. How does strength/training/tissue physiology attribute to the Adult age group? (2)
    • I. Strength declines 1% per year or 8% per decade after age 30
    • II. Faster rate for sedentary adults
  7. How does strength/training/tissue physiology attribute to the Late Adult age group? (4)
    • I. Strength declines 15-20% per decade in 60’s and 70’s; 30% per decade thereafter
    • II. Focus: Function, delaying muscle atrophy, and improving endurance and strength
    • III. PT for strengthening is appropriate but documentation must show functional progress
    • IV. Modification of traditional resistance program to accommodate multiple conditions and degenerative joint disease
  8. What initial gains in strength attributed to neurological response? (3)
    • I. Motor learning
    • II. Improved coordination
    • III. Increased recruitment of motor units firing
  9. ______ __________  a change over time in the responsiveness of the sensory system to a constant stimulus.
    Neural Adaptation
  10. ___________ is an increase in muscle size due to increased size of myofilaments.
    Hypertrophy
  11. Length in time/intensity to train for muscle hypertrophy?
    Requires 4-8 weeks of moderate to high intensity activity
  12. Length in time/intensity to train for muscle hyperplasia?
    Current research does not support the theory of increasing number of muscle fibers
  13. Adaptation of other tissues with resistance exercises (3)
    • I. Capillary density decreases with muscle hypertrophy
    • II. Tendon and ligament believed to increase in tensile strength
    • III. Bone Density- evidence is mixed but resistance training is often prescribed
  14. _________ __________ is thought to speed development of noncontractile soft tissues
    Eccentric resistance
  15. Pertaining to determinants of resistance exercise, define alignment.
    direction of movement replicates the action of the muscle group
  16. Pertaining to determinants of resistance exercise, explain stabilization
    external and internal tensile forces that maintain the structure
