Q

v02 mac

A

When VO2 is measured during max exercise

-Max volume of O 2 one can consume during exhausting exercise or
max rate of O 2 utilization of muscles during exercise

  • Aka….Maximum aerobic power (MAP)
  • Considered the BEST index of aerobic fitness

15
Q

unlike static

A

dynamic flexibility requires active force production
(your own muscles contracting).

  • Because it is difficult to quantify “stiffness”, dynamic is
    measured more subjectively

16
Q

Individuals with good flex have:

A
  • Greater ease of movement
  • Less stiffness of muscles
  • Enhancement of skill
  • Less chance of injury
  • Important in athletic performance
  • Important in ability to carry out ADL’s
17
Q

is too much flexibility a problem

A

YES
- May result in hypermobility
- increased ROM of joints beyond normal, acceptable
values

18
Q

hypermobility leads to…

A

joint laxity
- increase risk of MSK injuries
- Shoulder dislocations occur because
of joint lax & hypermobility
(gymnasts & swimmers)
- very difficult to have too much flex

19
Q

Decreased ROM is a deficit under the following conditions

A

decreased ROM alters the normal mechanics of a movement

  • joint ROM is not within normal limits for a sport or task
  • decreased ROM is the result of an injury & the ROM is not restored to
    preinjury levels
  • decreased ROM creates asymmetry bilaterally
  • Correct deficits with stretching (static/PNF)
20
Q

muscle spindles

A

Sensitive to the rate of change in muscle length
* Spindle activity is directly proportional to speed of movement
* Rapid stretch will cause a CONTRACTION
* Example: patellar reflex

21
Q

golgi tendon organ

A

Inverse stretch reflex

  • Lies within a tendon near its attachment to the muscle
  • Detects tension applied to the tendon as a result of muscle
    contraction

-Increase tension/contraction (detect
by GTOs) will cause RELAXATION

  • Example: Dropping a heavy deadli
22
Q

DIRECT Assessments of flexibility

A
  • Goniometer
  • Inclinometer
  • Leighton flexometer
23
Q

INDIRECT Assessments of flexibility

A

-Sit n reach
- Sit n reach variants

24
Q

pros and cons to goniometer

A
  • Cheap (~$40)
  • Direct measure
  • Difficult to find bony landmarks
  • Upper-extremity joints are generally more reliable than ROM of lower
    extremity
  • Cannot be used with spine…instead use inclinometer
25
Q

inclinometer pros/cons

A
  • Easier to use than the flexometer & goniometer
  • Held by hand on moving body segment during measurement
  • Does not have to be aligned with specific bony landmarks
  • Pricey (~$450
26
Q

leighton flexometer pros/cons

A
  • Quantifies ROM in degrees
  • Protocols are standardized
  • Does not require locating very specific joint axis of rotation or
    bone segments
  • There are ~24 standardized joint action protocols
  • Normative data available
  • Valid & reliable
27
Q

indirect

A

movement of joint is not measured in degrees;
measured in inches or centimeters

  • Does not provide an accurate measure of actual joint range of
    motion but is very practical
  • Can be very reliable as tests are easy to standardize but validity is
    questionable
28
Q

muscular strength

A

Ability of a muscle or muscle group to develop maximal contractile force
against a resistance in a single contraction with proper technique

29
Q

absolute strength

A

total amount of weight lifted without adjustment for the participant’s body mass;
for example 1RM weight

30
Q

relative strength

A

total amount of weight lifted with some type of adjustment for the participant’s
body mass;

ex: Divide the strength test outcome by body mass to give a strength:mass

31
Q

muscular endurance

A

The ability of the muscle to apply a submaximal force
for extended periods

  • Can be via repeated contractions (dynamic) against a load for an
    extended period or a sustained muscular contraction (isometric)
32
Q

Submaximal repeated contractions (Dynamic)

A
  • 1) Absolute submax load (%1RM)
  • 2) Relative submax repetitions (pushups, CSEP-CPT, curl-ups)
33
Q

Sustained Muscular Contraction (isometric)

A

1) Timed contractions to failure (back extension, plank CSEP-CPT, Wall sit)
