Chapter 12: Flexibility, Body Weight, and Stability Ball Exercises Flashcards
T/F: Flexibility training is most important in reducing chance of injury
F
The ability to move a joint freely through its full ROM
flexibility
What is the main purpose of a warm up
elevate core temperature
When should flexibility training be included before a workout
when the workout includes dynamic activity such as basketball
when should flexibility training be included after a workout
when a workout includes less dyanmic activity such as a stationary bike, or stair climber
T/F: some evidence shows that increased flexibility may also provide increased resistance to muscle injury
T
The ability to move effectively depends on this
strength with coordination
A common problem with low back pain is this condition resulting from tightness, or weakness in certain muscle groups
anterior tilt
These factors are controllable by the client to enhance flexibility 4
muscle and connective tissue elasticity
core temperature
activity level
training program
These factors are uncontrollable by the client in regards to flexibility 3
joint structure
age
sex
T/F: flexibility is joint specific
T
This is the major limiting factor to ROM under normal circumstances
muscles and connective tissue
most of the difference between individuals in static ROM is do this this
elastic properties of the muscles and tendons attached to the joint
This property of muscle and connective tissues is altered as a result of stretching exercises
elasticity
When a muscle is held for a period of time under tension in a static stretch, the passive tension in the muscles declines, the muscle ‘gives’ a little or relaxes
viscoelastic stretch relaxation response
the amount of external force required to lengthen the relaxed muscle
passive tension
How long can the increased pliability of a muscle/tendon be sustained after the stretch
90 minutes
The muscle crossing over or adjacent to a joint will also effect this
flexibility
The more easily this yields, the less energy is spent overcoming their resistance
antagonistic muscles
Excessive ROM in the joint, just as in the case of this can increase the opportuinity for injury
Hyperlaxity
this condition allows the joints to achieve a ROM that exceeds what is considered normal
hyperlaxity
The best time to start a flexibility training program
young children, before puberty
The low point in flexiblity (age) occurs at this point in development
between the ages of 10-12
Differences in the structure of the trunk, hips, and ankles are reasons why this sex is more flexible
females
Increases in muscle size, stature, and muscle strength are reasons why this sex is less flexible
males
ROM is positively affected by this type of change in core temperature
increase
The decrease in flexibility in inactive people primarily occurs because this
connective tissue becomes less pliable when exposed to only limited ROM
T/F: resistance training can increase flexibility
T, if well-designed, properly executed, and performed through the entire ROM
T/F: resistance training can decrease flexibility
T, if the program emphasizes high loads performed through less than a full ROM
What is the reason why flexibility can be impaired from resistance exercise
improper development of a muscle or group of muscles around a joint
Two different tissue adaptations targeted by flexibility training
elasticity
plasticity
the ability to return to original resting length after a passive stretch
elasticity
the tendency to assume a new and greater length after a passive stretch
plasticity
