本研究的目的在比較有氧舞蹈低衝擊和兩種高衝擊前
舉膝動在動力學及運動學的變化情形。以十七位大學體育
系、所女學生為受試對象,平均身高為 163.5 ± 4.2 公
分,平均體重為 54.6 ± 6.2 公斤,平均年齡為24.2 ±
2.7 歲。運動學及動力學的資料使用一部 PEAK 高速攝影
機 (120Hz) 及 KISTLER 9287 型的測力板 (1200Hz) 同
步收集。統計的方法是使用重覆量數單因子變異數分析 (
α =.05),達到顯著差異後再使用杜凱氏法進行事後比較
。
結果指出在準備期中平均的垂直地面反作用的範圍為
體重的 1.63 到 2.71 倍,平均撞擊衝量為0.177到0.268
體重×秒。著地期中平均的被動作用力範圍為體重的0.44
到 1.57 倍,平均被動衝量為 0.019 到 0.033 倍體重×
秒, 而平均的第一垂直地面反作用的範圍為體重的 1.08
到 3.06 倍,平均第一撞擊衝量為 0.134 到 0.153 倍體
重×秒。 而平均的第二垂直地面反作用的範圍為體重的
1.08 到 1.16 倍,平均第二撞擊衝量為 0.417 到 0.512
倍體重×秒。在增加落下的高度時,髖、膝、踝關節彎曲
的角度會逐漸增加。
結果指出,兩種高衝擊所承受的負荷顯著大於低衝擊
。因此建議當做高衝擊動作時利用下肢關節做較大的彎曲
,以延長作用力的時間來減少負荷。
The purpose of this stydy is to analysis the
kinematic and kinetic differences of drop landing
from low impact front knee lift and two of high
impact(F.K.L)aerobic dance movements.Ten under-
graduateand seven graduade female students seve-
red as the subjects for this study.There mean hei-
ght,weight, and age were 163.5 ± 4.2cm,54.6 ±
6.2kg, and 24.2 ± 2.7 years espectively.Kinematic
and Kinetic data were acquired stimultaneously by
using a PEAK high speed camera(125Hz)anda KISTLER
force plate (1200Hz).The variables were tested by
one-way repeated ANOVA ( α =.05) and the tukey m-
ethod posterior comparisions.
The results indiated the range of the propuls-
ion plase of peak ver- tical ground reaction force
were 1.63 to 2.71 BW(Body Weight), peak impact
impulse were 0.177 to 0.268 BW × s(Body Weight ×
second).
The range of the landing phase of passivefor-
ce were 0.44 to 1.57 BW,passive impulse were 0.019
to 0.033 BW × s.First peak vertical ground
reaction force were 1.08 to 3.06BW,first peak
impact impulse were 0.134 to 0.153 BW × s.Second
peak vertical ground reaction force were 1.08 to
1.16 BW,second peak impact impulse were 0.417 to
0.512 BW × s.Significant increase were found in
hip, knee, and ankle joint flexion as drop heiht
increased.
The results indiated that the load of the two
high impact(F.K.L)was significantly higher than
the low impact(F.K.L).It is suggested that the
aerobic dancers should use joints flexion and
longer action time to reduce the load.
The purpose of this stydy is to analysis the
