Ch 17 Warm up

Match each term with correct definition

• Dynamic balance

• The ability to maintain the center of mass within the base of support in a stationary position, meaning no linear or angular movement.

• Semi-dynamic balance

• The ability to maintain the center of mass with a stationary base of support yet allowing movement for the base supporting the body.

• Static balance

• The ability to maintain a center of mass over an ever-changing base of support.

Categorize is method of challenging balance into the system is affects

Groups:

(a) Visual

,

(b) Vestibular

,

(c) Somatosensory

• turning head side to side

• looking ahead while rotating the body

• shoes vs barefoot

• eyes closed

• light to dark environment

• change the balance surface

Organize these options into the right categories based on the progression phase of balance

Groups:

(a) Progression 1

,

(b) Progression 2

,

(c) Progression 3

• single leg catch and throw

• Improve reflexive muscle contractions (stretch reflex) and increase joint stability

• single leg box jump with stabilization

• Lateral hop with stabilization

• single leg balance reach

• single leg squat

• Hopping motions with single leg landing holds

• Develop proper deceleration ability from moving to stationary position

• Balance leg can move through a range of motion with a stabilization

• • mprove dynamic eccentric and concentric movement of the balance leg through full ROM 

• No joint movement of balance leg

• side step up to balance
