Balance exercises used for introducing balance training should initially involve little joint motion and improve what type of contractions?
Preplanned voluntary contractions
Reflexive (automatic) joint-stabilization contractions
Voluntary contractions
No muscle contractions are involved in balance training.
Reflexive (automatic) joint-stabilization contractions
Not Voluntary contractions because Voluntary contractions may occur too slowly for early balance training contractions.
T/F
Single-leg squat training uses dynamic, eccentric, and concentric movement of the balance leg
True
From this question
Which balance training exercise is part of the second stage of balance training that uses dynamic, eccentric, and concentric movement of the balance leg through a full range of motion?
Single-leg balance
Single-leg squat
Single-leg lift and chop
Multiplanar hop with stabilization
Not quite!
You answered incorrectly.
The multiplanar hop with stabilization is a task that is developed to cause proper deceleration to move the body from a dynamic state to a controlled stationary position. This task is in the third stage of balance training.
Stage 3 balance exercise should include what types of motion?
Moving only the balance leg through a full range of motion
Hopping motions with a single-leg stance landing
No motion
Little motion
Hopping motions with a single-leg stance landing
Not Moving only the balance leg through a full range of motion
Moving only the balance leg through a full range of motion is found in stage 2 balance exercises.
For balance training, a postural disturbance being added to a task in order to make the task more difficult
Perturbation
A perturbation is a mechanism where a postural disturbance is added to a task, which causes the client to learn to maintain or recover balance. An example would be lightly pushing on a client’s shoulders when they are balancing on one foot.
Which sense provides information about changes in pressure on the skin, muscle length, and joint angles?
Somatosensory system
Feedback to the body through the somatosensory system incorporates information about pressure to the body, change in body segment position, or change in muscle length.
T/F
the Somatosensory system tells about changes in muscle length and joint angles?
True
It does pressure, muscle length angles
When performing high-velocity movements with medicine balls, the ball weight should be no more than what percentage of the user’s body weight, according to current recommendations?
20%
40%
30%
10%
That’s the current recommendation apparently
T/F
Systolic pressure is the maximum blood pressure during contraction of the ventricles; diastolic pressure is the minimum pressure recorded just prior to the next contraction.
True
Both are true
T/F
Systolic pressure is the maximum blood pressure during CONTRACTION OF the ventricles
