Q

how do you measure grip endurance ?

A

using hand dynamometer, record initial force and final force at end of 1 minute
- final force/initial force x 100 = % decline in force production

Q

5 points about variale resistance machines (pros and cons)

A
  • difficult to match strength curves of difference muscle groups
  • difficult to assess clients actual strength because force is altered throughout ROM
  • no spotter required
  • dont fit everyone
  • more beneficial for training than testing

Q

how do you admin the cunnginham test

- what is its reliability

A

treadmill 20% grade, 8mph

  • measured by seconds to volitional fatigue
  • 0.79-0.91 (low is not doing it properly, also a learning effect and comfort effect)
23
Q

wingate test measures what?

  • what is its reliability ?
  • what do you set resistance to?
A
  • measures leg power
  • 0.89-0.98
  • 7.5-10% BW for resistance
  • peak (5s and mean (30s) power output
24
Q

the margaria-kalamen stair sprint test predicts what from what?
- what 3 things are sued to estimate ?

A

power from amount of time individual sprints up a set of stairs (3 at a time)
- vertical distance travelled, subjects mass, and time

25
what is the equation for power for the margaria kalamen test
(mass x 9.81 x distance)/time
26
the vertical jump test can be scored as? (3)
height jumped power force
27
the ability to perform a movement within a short period of time
speed
28
the ability to rapidly change the position of the entire body in space, with speed and accuracy
agility | - involves braking, changing direction and accelerating again
29
what do you want sprint tests to be short
so energy system does not get involved
30
5 things to consider when testing speed and agility
- proper footwear - non slip surface - timing is everything - proper warm up and submaximal practical trials - start smart and finish strong
31
how do you administer the 40 yard sprint
- cones on flat surface (deceleration zone as well) - sprint included warm up and 2 practice trials, sub max intensity - start behind line, start stop watch on first movement - 2 trials with 3 mins in between - compare to norms
32
what can you calculate from the 40 yd sprint test
power, velocity, or acceleration
33
T test and illinois are what ?
agility test
34
4 types of flexibility
static (still), dynamic (moving), passive (someone holding or moving your limb), active (you are moving or holding limb)
35
4 purposes of flexibility testing
1. ensure participant can perform activities with minimal on muscle tendon tissues 2. monitor improvements and declines of training 3. identify problem areas that may be associated with poor performance or possible risk of injury 4. assess the rehab procedure following injury and assist in the suitability of an individual to participate in certain activities
36
5 general guidelines for flexibility testing
1. have client perform general warm up and static stretching 2. avoid fast jerky movement and stretching to pain 3. administer 3 trials 4. compare best score to available norms 5. use test results to identify and muscle groups in need of improvement
37
3 limiting factors affecting flexibility
1. there are no valid tests of general flexibility 2. flexibility is highly specific to the joint and surrounding tissue 3. what structures are most important in reducing resistance ? (i didn't write this answer)
38
other limiting factors to flexibility
- warm up - age - gender - inactivity - body type - size and strength of opposing muscle group
39
goniometer takes a ____ measure of flexibility
direct
40
goniometry can be very reliable and valid if?
proper protocol is followed (technician skill)
41
intratester and intertester reliability of goniometric measurements affected by?
identification of axis of rotation and palpating bony landmarks
42
high agreement between ROM measured by ________ and universal ________
radiographs, goniometers
43
how do you measure with the goniometer
1. place the center of the instruments so it coincides with the fulcrum, or axis of rotation, of the joint 2. align the arms of the gonioemeter with bony landmarks along the longitudinal axis of each moving body segment 3. measure the ROM as the difference between the joint angles and at the extremes of the movement
44
2 examples linear measurements of flexibility
1. sit and reach | 2. back scratch test
45
2 types of indirect measurement of flexibility
visual estimation and linear measurements
46
the sit and reach test is moderately related to ______ flexibility and poorly related to _______ flexibility - poor _____ _____ validity and unrelated to self reported _____
hamstring, low back | criterion related , back pain
47
sit and reach test is to evaluate?
the static flexibility of the lower back and hamstring muscles
48
the ability to keep the body's center of gravity within the base of support when maintaining a static posture, performing voluntary movements, or reacting to external disturbances
balance
49
4 principles of balance
1. balance training is emerging ad one of the top 10 exercise trends 2. gaining recognition of component of functional fitness 3. for seniors, extremely important to maintain independent living status and successful completion of ADLs 4. helps prevent falls
50
______ training is emerging ad one of the top 10 exercise trends
balance
51
what is a direct measure of balance
force plate | - anterolateral and mediolateral coordinates of the center of pressure are derived
52
the force plates provides data about ? (3)
1. postural sway 2. steadiness, 3. weight distribution
53
con of the force plate
Expensive!
54
what is an indirect measure of balance
1 leg stance
