Abstract:

BACKGROUND: Aging in human beings is correlated with a decline in neuromuscular function and performance. It directly results in alterations of force-velocity relationship in muscles. The alterations above have direct functional implications which causes the loss of activities of daily living and self-care ability.
OBJECTIVE: To review the changes of the force-velocity relationship with age and the functional implications caused by these changes.
METHODS: Databases of CNKI, Duxiu, Elsevier SD, and Springer Link were searched. Documents related to changes laws of force-velocity relationship with age and the functional implications caused by these changes were included. Repetitive research or Meta analysis was excluded.
RESULTS AND CONCLUSION: Totally 46 literatures were included in this review. The findings demonstrated that: Strength of muscles, especially power and contraction velocity, are declined with aging. It is directly associated with loss of daily living and self-care abilities. The decline of power is highly related to functional ability. Thus, amelioration of muscle power can effective improve the functional ability and elevate life quality of aging people.
