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
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
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).
Individuals with good flex have:
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
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
-Increase tension/contraction (detect
by GTOs) will cause RELAXATION
