Q

reliability vs validity

A
  • reliability is the consistency or repeatability of test scores, data, or observation
  • validity is the degree of truthfulness of a test score, referring to the extent to which a test measures what it proposes to measure

17
Q

relationship b/w strength and endurance

A

-not good

18
Q

origin

A
  • for skeletal muscles
  • where the attachment to the bone is
  • does not move
  • closer to body
19
Q

insertion

A
  • for skeletal muscles

- further from body

20
Q

origin

A
  • for skeletal muscles
  • where the attachment to the bone is
  • does not move
  • closer to body
21
Q

insertion

A
  • for skeletal muscles
  • further from body
  • attachment of the muscle on the bone that moves
22
Q

afferent

A

-transmission into brain

23
Q

efferent

A

-transmission away from brain

24
Q

intermuscular coordination

A

between muscles

25
Q

intramuscular coordination

A

within muscles

26
Q

intermuscular coordination

A

between muscles

-interplay between muscles that generate movement through contraction

27
Q

distal

A

farther from the trunk

28
Q

absolute strength

A
  • the greater the active body mass, the greater the absolute strength
  • tested with one rep
29
Q

relative body strength

A

-maximum strength / body mass

30
Q

relationship b/w strength and power

A

-strong relationship

31
Q

relationship b/w strength and endurance

A

-not good

32
Q

relationship b/w strength and muscular endurance

A
  • downward slope

- as strength increases, body mass decreases

33
Q

cortical bone

A
  • low porosity
  • less flexible
  • can resist great stress
  • long bones
  • gravity supporting bones
34
Q

intramuscular coordination

A

within muscles

-capacity to activate motor units simultaneously

35
Q

tendon makeup in skeletal muscles

A

from big to small:

  • tendon
  • muscle belly
  • muscle fiber bundle
  • muscle fiber
  • sarcolemma
  • myofibril
  • sarcomeres
36
Q

sarcomere

A
  • made up of actin filaments

- h zones inside of actin filaments

37
Q

static/isometric contraction

A

-no visible change in muscle length

38
Q

dynamic contractions

A
  • involves movement

- concentric, eccentric, isokinetic, plyometric

39
Q

plyometric contraction

A

-sudden eccentric loading & stretching followed by a concentric contraction

40
Q

eccentric contraction

A

-muscle cannot develop sufficient tension, overcome by load, lengthens during movement

41
Q

isokinetic contraction

A

-neuromuscular system works at constant speed during each phase of movement against a preset high resistance
