peak
genera test termination criteria for all v02 max protocals
Moderate to severe angina
- Excessive (>10mmHg) ↑ in BP (especially systolic)
- Shortness of breath, wheezing, leg cramps
- Signs of poor perfusion (light-headed, confusion, nausea, cold/clammy skin)
- Failure of HR to ↑ with exercise
- Noticeable change in heart rhythm
- Physical or verbal manifestations of severe fatigue
- Equipment failure
- Subject asks to stop
Oxygen consumption (VO2)
The volume of O 2 used by the body under given conditions
- Can be measured at rest, during submax exercise, or during max exercise
v02 mac
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
absolute v02
TOTAL volume of o2 taken into the body
relative vo2
volume of o2 taken into the body RELATIVE TO BODY WEIGHT
static flexibility
measure of the total ROM at a joint
dynamic flexibility
measure of the resistance developed during stretching throughout ROM
unlike static
dynamic flexibility requires active force production
(your own muscles contracting).
- Because it is difficult to quantify “stiffness”, dynamic is
measured more subjectively
Individuals with good flex have:
- 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
is too much flexibility a problem
YES
- May result in hypermobility
- increased ROM of joints beyond normal, acceptable
values
hypermobility leads to…
joint laxity
- increase risk of MSK injuries
- Shoulder dislocations occur because
of joint lax & hypermobility
(gymnasts & swimmers)
- very difficult to have too much flex
Decreased ROM is a deficit under the following conditions
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)
muscle spindles
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
golgi tendon organ
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
DIRECT Assessments of flexibility
- Goniometer
- Inclinometer
- Leighton flexometer
INDIRECT Assessments of flexibility
-Sit n reach
- Sit n reach variants
pros and cons to goniometer
- 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
