Angle of inclination
Edit
The angle is widest in infancy, and becomes lessened during growth, so that at p
uberty it forms a gentle curve from the axis of the body of the bone. In the adu
lt, the neck forms an angle of about 125° with the body, but this varies in i
nve
rse proportion to the development of the pelvis and the stature. The angle decre
ases during the period of growth, but after full growth has been attained it doe
s not usually undergo any change, even in old age
幫維基百科補充:
其他部位的活動度也有變化~
eg 胸椎: 上學年齡以後活動度通常都會減少, 而且幾乎所有人胸椎都會變得比較前彎
然後韌帶也是有==
陳述恐怕要寫太長了
大人能不能練起來呢?
可以, 而且通常能達到業餘運動員不錯的水準
不過這邊應該沒人想知道==
你想知道的話我有空在寫
