A study on Isokinetic muscular strength of knee joint - concentric contraction and eccentric contraction -

&nbsp;&nbsp;Seoul, Korea In compensation for the number of 14 male students in physical education major, the study abtained the fellowing conclusion that the result of measuring Isokinetic Strength was showed by the muscle measurement of muscle strength fellowing muscle contraction of knee joints eccentric and concentric contraction though Cybex Norm&lt;SUP&gt;TM&lt;/SUP&gt;.<BR>&nbsp;&nbsp;1. Peak torque and % peak torque decreased in according to the increase from 60°/sec to 180°/sec at the angle of flexion and extension when having the eccentric and concentric contraction, and have also higher eccentric contraction than the concentric contraction when having the flexion and extension and have higher extension and the flexion.<BR>&nbsp;&nbsp;2. In H/Q ratio, the angle&quot;s velocity increased in according to the addition from 60°/sec to 180°/sec when having the concentric contraction and had the similar tendency when having the eccentric cotraction. In H/Q ratio has a higher average eccentric contraction at the 60°/sec of the angle&quot;s velocity and have also higher concentric contraction at the 180°/sec of the angle&quot;s velocity.<BR>&nbsp;&nbsp;3. The average power and % average power increased in according to the addition from 60°/sec to 180°/sec at the angle&quot;s velocity of flexion and extension when having the concentric and eccentric contraction, and have also higher extension than flexion.<BR>&nbsp;&nbsp;In 60°/sec of the angle&quot;s velocity, the average power and % average power have higher eccentric contraction than the concentric contraction. when having the flexion and have also higher concentric contraction when having the extension.<BR>&nbsp;&nbsp;In 180°/sec of the angle&quot;s velocity, the average power and % average power have higher eccentric contraction than the concentric contraction and have also higher eccentric contraction when having the extension.<BR>&nbsp;&nbsp;4. The total work and % total work decreased in according to the increase from 60°/sec to 180°/sec at the angle&quot;s velocity and concentric contraction. and have higher extension than the flexion.<BR>&nbsp;&nbsp;In 60°/sec of the angle&quot;s velocity, total work and % total work have higher eccentric contraction than the concentric contraction when having the flexion, and have also higher eccentric contraction when having the flexion.<BR>&nbsp;&nbsp;In 180°/sec of the angle&quot;s velocity, total work and %total work have higher eccentric contraction than the concentric contraction when having the flexion. and have also higher eccentric contraction when having the extension.
