65
among the elderly, increased gait speed= lower risk for
falling/fractures
66
balance

67
high balance translates to more
efficient movement, posture and bodily control
68
balance is needed for
sport participation, activities of daily living, reduce the risk for injury/falls
69
balance improvements are neural based via the development of
adequate strength balance, optimal force coupling and proprioceptor education
70
