等速肌力測試

1、等速肌力測試主要指標(biāo)1PEAK TORQUE峰力矩：即在肌肉收縮時產(chǎn)生的最大力量輸出，反映肌肉收縮最大力量的能力，是肌肉絕對力量；Highest muscular force output at any moment during a repetition. This can be determined within each rep for the entire set. Peak Torque indicates the muscles maximum strength capability. This is also the equivalent to a 1-repetition ma

2、ximum (RM) isotonic strength test.Peak Torque can also be evaluated specific to time (Torque .20sec) or to ROM (Torque 30).2隨年齡增大而呈直線下降趨勢，同名肌運動速度相同時男性的峰力矩大于女性；體重越重，身高越高時峰力矩越大；可測試任一角度及時間點的峰力矩。3PEAK TQ/BW相對峰力矩，即相對于體重的峰力矩，更好地用來描述功能性活動，可以用來個體間比較。Peak Torque is represented as a percentage normalized to b

3、odyweight and compared to an estimated goal. This value is more relative and pertinent to functional activity.4ANGLE OF PEAK TORQUE峰力矩產(chǎn)生的角度，相同速度及相同活動產(chǎn)生峰力矩角度相同，一般出現(xiàn)在中間ROM，最大的長度-張力關(guān)系點。Defined as the point in the ROM where peak torque is produced. It usually occurs at the same range in the ROM for simi

4、lar movements and speeds. Angle of peak torque typically occurs in the mid range of a motion.5TIME TO PEAK TORQUE到達(dá)峰力矩的時間，即肌肉從開始收縮到產(chǎn)生最大力矩所需時間，反映肌肉快速產(chǎn)生力矩的能力。A measure of time from the start of a muscular contraction to the point of the highest torque development (Peak TQ). This value is an indicator

6、t bout.9AVG.POWERPower represents how quickly a muscle can produce force. An important value to evaluate as power development is important for injury prevention.平均功率向心收縮時當(dāng)運動速度達(dá)到一定時平均功率不再增加反而下降；離心收縮時隨運動速度加快而增加。10AGON/ANTAG RATIOImbalance may predispose a joint to injury as opposing muscle groups provide dynamic joint stability.屈伸比61.4%74.4%比值隨速度加快而增大11Following concentric exercise, CK activity reached a peak value of 1150 364 IU/l after 24 h recovery. Eccentric mode was followed by a significantly gre
