Week 5 Flashcards
Lecture 5:
Define flexibility
The ability to move a joint through its complete, pain-free range of motion
Lecture 5:
What is Static Flexibility?
Full range of motion of the joint & is dependent on the musculotendinous unit too
Lecture 5:
What is Dynamic Flexibility?
Rate of torque or resistance developed during stretching throughout range of motion
Lecture 5:
What is the difference between Active & Passive movement & flexibility?
Active = opposing muscles contract
Passive = no contraction of opposing muscles (using other body part to push for stretch or external forces)
Lecture 5:
What are 4 determinants of flexibility limitations?
1.) Joint capsule type
2.) Adequate warm-up - combine dynamic & static stretching
3.) Muscle viscosity - very limiting part of flexibility
4.) Compliance/tightness of other tissues - can increase or decrease flexibility
Lecture 5:
Does age affect flexibility?
Yes, when you get older you’re typically more sedentary & PA decreases while chronic diseases increases
- not as much the actual number, moreso the trends of aging
Lecture 5:
Does body type affect flexibility?
Moreso dependent on the individual, but possibly can be an influence
- muscle mass vs fat mass etc
Lecture 5:
Does gender/sex affect flexibility?
Yes
- women more flexible due to hormone levels & pelvis structure (allowing larger joint angles)
Lecture 5:
Does physical activity & inactivity affect flexibility?
Yes, less active usually less flexible
- injuries cause less activity & less flexibility
Lecture 5:
Dies warming up affect flexibility?
Yes, but dependent on type of warmup
- so if proper with stretching, than yes flexibility will increase for short time
Lecture 5:
Does previous injury affect flexibility?
Yes
- eg; sprain over stretches so may mean more flexible
Lecture 5:
Wheat are a few reasons why flexibility is so important?
- decrease risk of injury
- increase quality of life & daily living
- increase overall range of motion
- reduce pain
- increase sport performance/outcomes
lecture 5:
What is Hypermobility?
- what can it cause?
Increased range of motion beyond the normal limit/acceptable value
- can cause instability & increase risk of injury
Lecture 5:
What is the Direct type/style of assessing flexibility?
Quantitive style Measuring amount of joint rotation in degrees using a goniometer (or flexometer/inclinometer)
- high agreement between ROM measured by goniometers
Lecture 5:
What is required for the Direct style of assessing flexibility?
Thorough knowledge & understanding of anatomy, axes of rotation, bony landmarks, & standardized testing procedures
Lecture 5:
What is the Indirect type/style of assessing flexibility?
Linear measurement of distances between body segments
- eg; sit & reach or back-scratch
Lecture 5:
What is the definition of balance?
Ability to keep the body’s center of gravity within the base of support when one is maintaining a static position, performing voluntary movements, or reacting to external disturbances
Lecture 5:
What are the 4 types of balance?
1.) Static
2.) Dynamic
3.) Reactive
4.) Functional
*various types of balance often work together
Lecture 5:
What is Static Balance?
Maintaining center of gravity in base of support while sitting or standing
Eg; standing on 1 foot
Lecture 5:
What is Dynamic Balance?
Maintaining upright position or balanced position while in motion
- eg; hopping on 1 foot
Lecture 5:
What is Reactive balance?
Compensating or recovering from other disturbances
- eg; standing on one foot & catching ball
Lecture 5:
What is Functional Balance?
The ability to perform activities of daily living (ADL’s) that involve balance
- eg; walking
Lecture 5:
What are 3 key systems that interact to maintain balance?
1.) visual system
2.) somatosensory (proprioception) system
3.) vestibular (inner ear) system
