Q

Factors affecting flexibility (6)

Body type
age
gender (Sex)
physical activity level
warm-up
amount of stretching & flexibility training
22
Q

Name the 2 body types that will score poorly on ROM tests

A

Bodybuilders

Obese individuals

23
Q

T or F: age decreases muscle stiffness, higher stretch tolerance

A

False

increase, lower

24
Q

Generally, ___ are more flexible than ____ at all ages

A

Females, males

25
This gender-related flexibility difference is attributed to (2):
Gender differences in pelvis structure & hormones that may affect connective tissue laxity
26
What may restrict ROM because of the tightening & shortening of muscle tissue?
Habitual movement pattern
27
T or F: lack of physical flexibility is a major cause of inflexibility
TRUE
28
What is disuse
Due to lack of PA or immobilization, produces shortening of the muscles & connective tissues
29
Warm up alone ____ increase ROM
does not | * active warm up + static or dynamic stretching is more effective
30
Often observed in certain athletes (gymnasts), leads to joint laxity or instability, may increase the risk of musculoskeletal injuries
Hypermobility
31
Name the 2 methods of measuring static flexibility
Direct | Indirect
32
Examples of direct methods (see p.24-30)
Goniometer Electrogoniometer Flexometer Inclinometer
33
Examples of indirect methods
Sit-and-reach tests Modified Schober Skin distraction test
34
T or F: Flexometer is easier to use than the inclinometer & universal goniometer
False, inclinometer is easier | Because held by hand + doesn't have to be aligned with specific bony landmarks
35
The validity & reliability of devices such as goniometers & inclinometers that measure ROM directly are highly dependent on: (2)
the joint being measured | technician skill
36
What is considered the best reference method for establishing the validity of goniometric measurements?
Radiography
37
The intratester and intertester reliabilities of goniometric measurements are affected by: (2)
Difficulty in identifying the axis of rotation | Palpating bony landmarks
38
Measurements of upper extremity joints is generally __ reliable than ROM measurements of lower extremity joints
More
39
Intertester reliability of inclinometer measurements is variable & joint specific to: (2)
Lumbar extension | Subtalar joint
40
Knowledge & skills required to obtain accurate & reliable ROM measurements (3)
Knowledge of anatomy Knowledge of standardized testing procedures Training & practice
41
T or F: There is a belief that lack of flexibility is associated with low back pain & musculoskeletal injuries
True
42
Sit-and-reach test
read p.36-48
43
Name the 2 measures of flexibility for older adults
Chair Sit-and-reach test | Back Scratch test
44
Assesses lower body (hamstring) flexibility
Chair Sit-and-reach test
45
Assesses upper body (shoulder joint) flexibility
Back scratch test
46
Increases the risk of developing low back pain
Lumbar instability
47
Name the primary muscle groups responsible for stabilizing the lumbar spine (3)
``` Trunk extensors (erector spinae) Trunk flexors (abs) Lateral flexors (quadratus lumborum) ```
48
Measures isometric endurance of trunk extensors
Sorensen Test
49
Measures isometric endurance of trunk flexors
V-sit Test
50
Measures isometric endurance of lateral flexors
Side bridge test
